Implant-supported Overdenture

[Year:2017] [Month:January-April] [Volumn:8 ] [Number:1] [Pages:33] [Pages No:22-25][No of Hits : 1060]


ABSTRACT

Edentulous patients often experience problems with their mandibular complete dentures. Patients with the resorbed mandibular ridge often complain of lack of stability and retention of the mandibular denture, together with a decreased chewing ability. While implant-supported fixed prosthesis offers many advantages, they are very expensive and not indicated in many conditions. Implantsupported removable prosthesis can be a choice of treatment in such cases. This clinical report describes a method to rehabilitate a patient with resorbed mandibular ridge with implant-supported overdenture.

Keywords: Implant, Restoration, Tooth replacement.

Submerged Plateau Implants: A Practical Solution for Mandibular Posterior Region

[Year:2017] [Month:January-April] [Volumn:8 ] [Number:1] [Pages:33] [Pages No:5-11][No of Hits : 753]


ABSTRACT

Introduction: Placement of endosseous plateau implants represents a valid treatment in the setting of limited alveolar bone height. This study’s objectives were to evaluate the effect of submerging and platform switching on crestal bone loss and redistribution of occlusal forces, the advantage of plateau design in providing more surface area for osseointegration, and the outcome of autogenous bone grafting from the implant osteotomy site as an alternate to exogenous bone graft.

Materials and methods: A prospective study of 10 patients with mandibular posterior edentulism was selected. Preoperative alveolar bone height (mean 11.87 mm) and width (8.22 mm) were measured on cone beam computed tomography. Twostaged implants were placed with 2.0 mm of submergence, which remained below the alveolar crest. The distribution of site according to bone quality and implant dimension was D2. Patients were followed up after 7 days for pain, infection, soft tissue dehiscence, and paresthesia followed by an average period of 1 year and evaluated for bone gain over implant shoulder, crestal bone loss, and peri-implant radiolucency.

Results: One-year postloading survival rates for submerged plateau implants was 100.0% in D2 bone, with no peri-implant radiolucency and statistically insignificant (ç-0.8 mm) crestal bone loss.

Conclusion: Submerged plateau implants have excellent survival rates and crestal bone level maintenance. The results of this study support the hypothesis that plateau implants can be successfully used in mandibular areas with limited bone height.

Dimensional Changes in Periodontium with Immediate Replacement of Tooth by Socket Shield Technique: Two-year Follow-up

[Year:2017] [Month:January-April] [Volumn:8 ] [Number:1] [Pages:33] [Pages No:17-21][No of Hits : 725]


ABSTRACT

Extraction socket healing and osseous remodeling take 120 to 180 days. Healing results in 50% reduction in the buccolingual bone in 12 months. Buccal bone loss of the extraction socket exceeds more than two-thirds with reduction in apicocoronal height by approximately 0.8 mm within 3 months of healing. Bundle bone is the portion of alveolar bone where fibers from the periodontal ligament (PDL) insert. A clinical technique was developed to preserve the bundle bone and the surrounding PDL through retention of buccal tooth root portion. This clinical case describes about immediate tooth replacement with an implant by preserving the buccal root in the anterior maxillary region with a 2-year follow-up. The hard tissue comparative correlation pre- and postoperative was measured using multislice computed tomography scanner (MSCT) and soft tissue by pink esthetic score (PES). The result after 2 years of evaluation was promising with negligible changes in hard and soft tissues. The study predicts encouraging results for immediate replacement of hopeless tooth in anterior maxilla without the use of augmentation materials. The surgeon should be experienced as the skills require expertise and knowledge.

Mini-implant supported Orthodontic Molar Intrusion: An Unconventional Approach for Pre-implant Prosthetics

[Year:2017] [Month:January-April] [Volumn:8 ] [Number:1] [Pages:33] [Pages No:26-30][No of Hits : 637]


ABSTRACT

Aim: To demonstrate two cases in which mini-implant-supported orthodontic molar intrusion has been performed to regain ideal crown height space (CHS) for implant prosthesis.

Background: Tooth loss is associated with esthetic, functional, and psychological consequences on an individual. Replacement of missing teeth by dental implants has gained significant importance due to promising advantages of implants over conventional prosthesis. Edentulism often results in supra-eruption of antagonistic teeth into the edentulous site, resulting in reduced vertical dimension for tooth replacement, posing a restorative challenge for clinicians. Hence, it is necessary to regain the lost vertical dimension prior to the implant prosthesis, either conventionally by endodontic and prosthetic intervention or by orthodontic intrusion with the aid of temporary anchorage devices (TADs). Mini-implants are a category of TADs that provide a minimally invasive technique for molar intrusion.

Case report: Two patients with missing mandibular molars desiring tooth replacement presented with supra-eruption of antagonist teeth, posing a difficulty during prosthetic treatment. Orthodontic intrusion using mini-implants was performed to regain the lost vertical space simultaneously along with dental implant placement followed by prosthetic rehabilitation.

Conclusion: The present twin case report demonstrates the successful role of mini-implants in orthodontic molar intrusion for establishing an ideal CHS for implant prosthesis to reestablish masticatory function.

Clinical significance: The twin case report demonstrates miniimplant- supported orthodontic molar intrusion as a replacement for conventional gross tooth reduction, for regaining the lost vertical space in cases of supra-eruption of maxillary molar associated with edentulism.

Keywords: Implants, Intrusion, Mini-implant, Preprosthetic orthodontics, Temporary anchorage device.

Comparative Evaluation of Clinical and Radiological Outcomes of Immediate and Delayed Dental Implant Rehabilitation: A Prospective Study

[Year:2017] [Month:January-April] [Volumn:8 ] [Number:1] [Pages:33] [Pages No:12-16][No of Hits : 636]


ABSTRACT

Introduction: The original implant surgical protocol proposed by Bran Mark et al involves open flap access, stepwise osteotomy of the bony ridge, and implant placement followed by good primary closure.

Objectives: To compare the radiographic marginal bone loss, pocket depth, clinical outcome associated with immediate and delayed implants, and success rates 2 years after the placement of implants.

Materials and methods: Totally 62 dental implants were placed in 42 patients. They were randomly selected to the immediate or delayed group. Among those selected, 30 were immediate implants and 32 were delayed implants. The width and depth of marginal bone defects around the implants were measured clinically just after placement and 3 months later at the abutment surgery. Bone healing and marginal bone changes were evaluated radiographically and clinical parameters evaluated were pocket depth, local infection, altered sensation, soft tissue dehiscence, pus discharge, implant mobility, and patient’s satisfaction. All the collected data were subjected to statistical analysis using Statistical Package for the Social Sciences version 17 software. Statistical analysis was done using Z test.

Results: The results revealed that there was a significant difference in pocket depth and crestal bone loss in both groups. Mean pocket depth in immediate group was 3.285 mm and mean pocket depth in delayed group was 3.523 mm at 1 year. There were minimal crestal bone losses in the immediate group as compared with delayed implant group at 1-year follow-up. Also, there were reduced complications, such as local infection, altered sensation, soft tissue dehiscence, and pus discharge in immediate implant placement group and resulted in patient’s satisfaction.

Conclusion: We conclude that the immediate dental implant placement is signi.cantly superior over the delayed implant placement.

“HN Turn to Drive Osteotome”: A Customized Device for Preparation of Osteotomy for Implant Placement

[Year:2017] [Month:January-April] [Volumn:8 ] [Number:1] [Pages:33] [Pages No:1-4][No of Hits : 597]


ABSTRACT

The density of available bone in an edentulous site has a primary influence on the treatment planning and the surgical approach chosen for osteotomy. In situations of inadequate bone density, osteotomes are a special set of hand instruments developed to form and shape bone, in preparation to placement of dental implants. Conventional osteotomes are optimally used by pressing the instruments into the bone and malleting into place using a surgical mallet. This article describes a variant of the conventional osteotome, which was indigenously developed to use the handdriven force for implant placement and, henceforth, eliminate the drawbacks of malleting procedures. This would aid hassle-free implant placement in edentulous areas with compromised bone quality and quantity.

Keywords: Hand driven, Implant bed preparation, Osteotome.

Implant Design and Stress Distribution

[Year:2016] [Month:May-August] [Volumn:7 ] [Number:2] [Pages:22] [Pages No:34-39][No of Hits : 3929]


ABSTRACT

Implant design refers to the three-dimensional structure of the implant, with all the elements and characteristics that compose it. Dental implants are subjected to various force magnitudes and directions during function. Because implants function to transfer occlusal loads to the surrounding biologic tissues, functional design objectives should aim to manage biomechanical loads to optimize the implant-supported prosthesis function. Thus, the primary functional design objective is to manage biomechanical loads to optimize the implant-supported prosthesis function. An implant has a macroscopic body design and a microscopic component of implant design. The microscopic features are most important during initial implant healing and the initial loading period. The macroscopic implant body design is most important during early loading and mature loading periods. The product used by the implant team may increase or decrease the risk of screw loosening, crestal bone loss, implant body bone loss, peri-implantitis, esthetics of soft tissue drape, implant failure, and implant body fracture. This article shall help the learner in making a judicious informed decision regarding the different factors governing the reduction of overall stress in implant fixtures and, thus, providing a better treatment to their patients.

Search strategy: A literature search was conducted using MEDLINE from 1975 to 2014 to identify studies, from simulated laboratory models, animal, to human, related to this topic using the keywords of implant biomechanics, implant macrodesign, thread pitch, thread geometry, thread depth, thread width, and implant crestal module.

Contact Allergy to Denture Resins and Its Alternative Options

[Year:2016] [Month:May-August] [Volumn:7 ] [Number:2] [Pages:22] [Pages No:40-44][No of Hits : 3443]


ABSTRACT

Intolerance to dentures as a result of allergy is very rare. In such cases, the allergy is triggered not by the acrylic but mostly due to the unpolymerized precursors. Epicutaneous test reveals the allergy is due to the presence of benzoyl peroxide initiator and hydroquinone inhibitor. In contrast, the monomers methyl methacrylate (MMA) and triethylene glycol dimethacrylate are allergens that are primarily responsible and relevant for dental clinicians and technicians in their jobs. Latex and vinyl gloves are not adequate barriers for monomer and are generally unknown as clinicians still work with doughy acrylic mixtures without adequate precautions. Research papers were reviewed—many papers were studies for their cytotoxicity effects of Methyl Methacrylate. Various reports mentioned in the literature make the monomer as the main felon. Allergen-free dentures as an alternative to denture base resins and precautionary measures for dental professionals and technicians have also been mentioned.

Keywords: Allergen-free denture, Allergy, Monomer.

Full-mouth Rehabilitation with Implant-supported Fixed Prosthesis.

[Year:2016] [Month:September-December] [Volumn:7 ] [Number:3] [Pages:32] [Pages No:73-80][No of Hits : 2020]


ABSTRACT

The objective of a dental prosthesis is to replace the teeth and adjacent tissues to restore function, esthetics, and speech. Oral rehabilitation of an edentulous patient is a challenge to the prosthodontist. Few patients have life-long problems with their complete dentures, such as difficulties with speech and mastication. Implant-supported prosthesis gives an opportunity to such patients a normal healthy life for their functional and esthetic demands. Implants are the most preferred treatment option to support and retain the fixed or removable prosthesis. Successful osseointegration enables both dentist and the patient to accept full-arch implant-supported prosthesis.
Literature is available on the use of full-arch fixed and removable implant-retained prostheses for completely edentulous patients; however, few patients are not satisfied with removable prosthesis even when supported by implants. Full-arch rehabilitation, a term used by many practitioners, has become a popular restorative option in prosthodontics. Full-arch implant-supported fixed prosthesis is a well-established treatment modality for edentulous patients. Longterm clinical studies have shown that this type of restoration can be successful for many years as success rates are high.
The aim of this study is to present a case report on full-mouth rehabilitation with implant-supported fixed prosthesis for completely edentulous maxillary and mandibular arches.

A Comparative Evaluation of Immediate Implant Placement in Fresh Extraction Socket with and without the Use of Platelet-rich Fibrin: A Clinical and Radiographic Study

[Year:2016] [Month:September-December] [Volumn:7 ] [Number:3] [Pages:32] [Pages No:48-58][No of Hits : 1213]


ABSTRACT

Introduction: The goal of modern dentistry is to prevent tooth loss and provide a healthy dentition with optimal functional efficiency, structural balance, and esthetic harmony. With the increasing success rates of dental implants, clinicians and researchers have turned their approach toward making the duration of treatment shorter and more comfortable for the patient.

Materials and methods: A total of 20 sites were selected and randomly divided into two groups. Of these, 10 immediate implants were placed with platelet-rich fibrin (PRF), while the other 10 immediate implants were placed without any similar adjunct. The patients were prospectively evaluated clinically and radiographically using cone beam computed tomography.

Results: It was observed that the patients in test group are favored with rapid soft tissue regeneration, diminished vertical bone loss, and improve with early wound closure, which helps in achieving an esthetic outcome and better patient acceptance. It can be used to fill horizontal defect distance or jumping distance for complete resolution of the space.

Conclusion: Immediate implants with PRF lead to stimulation and acceleration of bone regeneration and show tendency toward rapid soft tissue regeneration and reduced peri-implant pain and inflammation. Overall, it is recommended to use PRF as a viable option in improving success and reducing the treatment duration in immediate implants.

[Year:2016] [Month:January-April] [Volumn:7 ] [Number:1] [Pages:24] [Pages No:1-6][No of Hits : 827]


Abstract

Objective: To use a systematic review to determine which all are the contributing factors that play role in success rate of orthodontic mini-implants.

Materials and methods: Different databases were searched without limitations up to July 2015. Additionally, the bibliographies of the finally selected articles were hand searched to identify any relevant publications that were not identified earlier. In vitro and in vivo articles were included. Both human and animal studies were included. Thirty five articles were initially selected, finally 28 articles were included in the study.

Conclusion: This review article conclude that success of orthodontic mini-implants depends on multiple factors which can be broadly classified under four headings- mechanical factors, biologic factors, placement technique, microbial factors. Mechanical factors included diameter of mini-implants, surface characteristics, load and its relation with implants, microgrooves, miniscrew versus manipulates, biologic factors included Inter-radicular space, skeletal growth pattern, placement site, racial factors, root proximity, placement techniques such as self-tapping and self-drilling placement, laser therapy, reinstalled mini-implants, pre drilling diameter play a vital role in success of implants. Microbial factors such as microbial floral changes after implant placement and inflammation surrounding the implants also have an important role in success and failure of implant.

An Introduction to the Longest Fixtures: Zygomatic Implants

[Year:2016] [Month:September-December] [Volumn:7 ] [Number:3] [Pages:32] [Pages No:59-63][No of Hits : 731]


ABSTRACT

Zygomatic implants have been used for dental reconstruction in patients with insufficient bone in the maxillary posterior region due to tumor resection, trauma, or atrophy. They are an alternative to bone grafting and distraction osteogenesis. Brånemark introduced these zygoma implants not only as a solution to obtain posterior maxillary anchorage but also to facilitate the rehabilitation process. The zygoma implant is a therapeutic option that deserves consideration in the treatment planning process and has become a rescue procedure that allows for continuity of care without resorting to a removable denture. The purpose of this study is to review the developments that have taken place in zygomatic implant placement over years, including anatomic information for installing the zygomatic implants, implant placement techniques, stabilization, and prosthodontic procedures.

Implant Supported Overdenture: A Step ahead from Edentulism

[Year:2015] [Month:September-December] [Volumn:6 ] [Number:3] [Pages:28] [Pages No:76-81][No of Hits : 2541]


ABSTRACT

Prosthetic rehabilitation of an edentulous patient with resorbed ridges involves various treatment approaches, such as complete dentures, implant supported fixed prostheses and implant supported overdenture. Complete denture in resorbed cases provides limited retention and stability hence ultimate acceptance by patient is reduced. Implant supported fixed prostheses gives a feel of natural teeth and a sense of satisfaction. But it is very costly, time consuming treatment requiring careful maintenance and in patients with inadequate lip support, it does not restore esthetics whereas implant-supported over denture provides excellent retention, stability, esthetics with cost-effective approach. It offers many practical advantages over conventional complete dentures and removable partial dentures. These include decreased bone resorption, reduced or eliminated prostheses movement, better esthetics, increased occlusal function and maintenance of the occlusal vertical dimension. In addition, implants supported over dentures also improve phonetics, the patient’s psychological outlook and quality of life.

This case report, intends to describe a patient with edentulous upper and lower arch. Because of resorbed lower arch the complete denture was not stable, so to meet the patient’s demands, implant supported over denture was planned. Treatment approach was modified at some steps to improve quality and longevity of restoration. The final restoration was stable, well retained and esthetically pleasing.

Immediate Implant Placement along with Bone Graft and Delayed Implants Placement in a Grafted Socket: A Comparative Study

[Year:2015] [Month:May-August] [Volumn:6 ] [Number:2] [Pages:28] [Pages No:40-47][No of Hits : 1914]


ABSTRACT

Purpose: A prospective study was performed to observe clinical outcomes of dental implants placed immediately after extraction with grafting of voids vs delayed implant placement in grafted socket after extraction of tooth/root.

Materials and methods: A total of 12 patients were enrolled in the study and randomly divided into two groups. In group I, implants were placed immediately with simultaneous bone grafting following the atraumatic extraction and osteotomy as required. In group II after extraction, socket preservation was done with alloplastic bone graft (synthetic tri-calcium phosphate and hydroxyapatite granules) on followed by implant placement after 3 months. The implant survival rates were assessed clinically and radiographically over a minimum of 3 months of follow-up.

Results: In the present study, with the help of the intraoral periapical radiograph, the distance from the marginal osseous level to the implant platform was measured in millimeters, on mesial and distal aspects of each implant for both the groups we found bone loss, invariably in both the groups, of which, bone loss was higher in group II than in group I at all the instances and was statistically significant. None of the other investigated factors (age, gender, pain, swelling, implant mobility, peri-implant mucosal inflammation and postoperative satisfaction) were statistically significant modifiers of success.

Conclusion: This study concludes that immediate implants with graft have less crestal bone loss and the graft within the socket consolidates more as compared to delayed implants with graft.

Keywords: Delayed implant, Hydroxyapatite bone graft, Immediate implant, Socket preservation.

Retrieval of Cold Welded Dental Implant Cover Screw using a New Technique

[Year:2015] [Month:September-December] [Volumn:6 ] [Number:3] [Pages:28] [Pages No:69-72][No of Hits : 1808]


ABSTRACT

Background: Cold welded cover screw is a rare mechanical complication. There is barely any literature on the etiology and removal techniques for the same. However, it can pose a serious problem and the screw needs to be removed, without damaging the internal threads of the implant, to initiate the prosthetic phase of implant therapy.

Aim: The aim of this paper is to report our experience with the retrieval of cold welded dental implant cover screw.

Case description: The present situation illustrates a new technique to retrieve a cold welded cover screw.

Conclusion: Removing a cold welded cover-screw from an implant can be difficult. There is no method of screw removal that can be universally applied. In this particular case, the screw was successfully removed using the prescribed technique. Therefore, this new technique may be used when removing a cold welded coverscrew from the implant.

Clinical significance: This technique is cost-effective, simple, and applicable to all available dental implant systems and can be effectively incorporated into the clinical situations in which the cold welded screws are not retrievable by conventional techniques.

[Year:2015] [Month:May-August] [Volumn:6 ] [Number:2] [Pages:28] [Pages No:35-39][No of Hits : 1182]


ABSTRACT

Background: The ancient ayurveda science of medicine describes various herbal preparations that achieve the hastening of bone healing and relieve from pain and swelling.

Aim: To evaluate the clinical efficacy of Cissus quadrangularis in pain management and bone healing after implant placement.

Objective: To evaluate the clinical and biochemical parameters using C. quadrangularis after implant placement in terms measurements of pain, swelling and serum alkaline phosphatase level.

Type of study: Prospective randomized control study.

Materials and methods: The patients were divided in two groups-study group and control group. Three patients in each group received implants either single implants or multiple implants. Study group was given C. quadrangularis without any additional medicine and control group was given routine antibiotics (amoxicillin 500 mg and diclofenac sodium). Pain was assessed using visual analog scale (VAS) at 3rd, 5th days and, after 1 week, swelling was checked in form of mild, moderate and severe. And, serum alkaline phosphatase was recorded preoperatively and 4th and 8th weeks of postoperative to evaluate bone healing.

Results: Pain and swelling are minimal, and bone healing is maximum in study and in control groups. There was an increase in serum alkaline phosphatase level at different follow-up in study groups compare to control group.

Conclusion: Use of C. quadrangularis after implant placement showed significant effect on pain and swelling management. Also rising level of serum alkaline phosphatase indicates new bone formation thus helps in osteointegration.

Rehabilitation of a Completely Edentulous Patient with a Mandibular Overdenture-supported by two Immediately Loaded Single Piece Implants

[Year:2015] [Month:May-August] [Volumn:6 ] [Number:2] [Pages:28] [Pages No:53-57][No of Hits : 1029]


ABSTRACT

For completely edentulous mandible, the rehabilitation modality of an implant retained overdenture on two implants placed in anterior mandible is a simple, acceptable and predictable treatment option. It contributes significantly to patients psychological and social well-being. Increased retention results in greater patient satisfaction than conventional removable complete denture. This case report describes the use of two single piece implants with ball attachments to retain an implant retained mandibular overdenture in order to rehabilitate a completely edentulous male patient. It also illustrates the approach of prosthetically driven implant placement.

A Comparison of Four Implant Abutment Connection Designs on the Stress Distribution Pattern using 3D Finite Element Analysis

[Year:2015] [Month:January-April] [Volumn:6 ] [Number:1] [Pages:34] [Pages No:1-8][No of Hits : 944]


ABSTRACT

The aim of this study was to evaluate the influence of four different implant abutment connection designs on the amount of stress dissipated on the implant, abutment screw, implant abutment interface and the bone when subjected to various loading conditions.
Computer aided design models of four different implant abutment connections, were constructed using Pro-Engineer 05. The 3D models were meshed using Hymermesh 11. Static load vertical loads 100 N were applied along the long axis of the implant at the central fossa and on the tip of buccal cusp. An oblique load was applied on the tip of the buccal cusp. This mesh was imported into ANSYS 13 to perform the numerical simulation.
The result showed that vertical loads closer to the implant long axis produced much lower Von Mises stresses than when loads applied away to the long axis of implant. The two types of conical connections dissipated the least amount of stress to the surrounding bone and most of the stresses were recorded at the implant abutment interface of these connections. The parallel hex connection showed a great amount of stress being dissipated to the abutment screw on vertical loading and most of these stresses were located at the 1st thread of the implant.

Conclusion: All the four implant abutment designs studied showed the least amount of stress on the various areas of the assembly and the surrounding bone, when the loads applied were close to the long axis of the implant. Both the conical connections proved to be the most favorable connections, and the parallel hex connection was the least favorable design. The tri-channel cylindrical connection design was stable on loads applied along and closer to the implant axis, but produced high amount of stress on the bone on oblique loads applied at a distance from the long axis of the implant.

Keywords: Conical connection, Implant abutment interface, Implant abutment screw, Internal hex connection, Stress distribution, Tri-channel connection.

Autotransplantation: Replacement to Restore Integrity

[Year:2015] [Month:May-August] [Volumn:6 ] [Number:2] [Pages:28] [Pages No:48-52][No of Hits : 693]


ABSTRACT

Autogenous tooth transplantation, or autotransplantation, is the surgical movement of a tooth from one location in the mouth to another in the same individual. Once thought to be experimental, autotransplantation has achieved high success rates and is an excellent option for tooth replacement. Although the indications for autotransplantation are narrow, careful patient selection coupled with an appropriate technique can lead to exceptional esthetic and functional results. This paper presents successful autotransplantation of a mature mandibular left third molar used to replace a mandibular left second molar. The mandibular second molar was nonrestorable due to vertical root fracture of distal root with furcation involvement and bony radiolucency. After extraction of mandibular second and third molars, the tooth was reimplanted into the extracted socket of second molar site. Six months of follow-up clinical and radiographic examination revealed satisfactory outcome with no signs or symptoms suggestive of pathology. In selected cases, autogenous tooth transplantation, even after complete root formation of the donor tooth, may be considered as a practical treatment alternative to conventional prosthetic rehabilitation or implant treatment.

An Insight into Different Innovative Techniques to Retrieve Cement-retained Implant Supported Prosthesis

[Year:2015] [Month:January-April] [Volumn:6 ] [Number:1] [Pages:34] [Pages No:9-16][No of Hits : 617]


ABSTRACT

Cement-retained restorations are the most commonly used restorations, though they can compensate for minor discrepancies in the fit of the prosthesis using cement and cement space but the major drawback is retrievability of such prosthesis. The increasing practice of permanently cementing the implant supported prosthesis is more likely to have biologic and technical failures.
This article describes various methods that simplify the retrievability of cement retained prosthesis. As the retrievability of the implant supported prosthesis is a basic consideration while delivering quality patient based treatment outcomes.

Replacement of Missing Maxillary Central Incisor with an Osseointegrated Implant-supported Prosthesis from an Orthodontic Perspective: A Multidisciplinary Approach

[Year:2015] [Month:May-August] [Volumn:6 ] [Number:2] [Pages:28] [Pages No:58-63][No of Hits : 591]


ABSTRACT

Over the last few decades, dentistry has brought in many new modalities of treatment for replacement of missing teeth. Treatment modalities for patients with missing teeth usually involve either space reopening and replacement or closure of the resultant space. The traditional option of using three-unit bridges for replacement of a single tooth involves loss of healthy tooth structure of two adjacent teeth and is a very aggressive treatment option. Osseointegrated implants have proven successful conservative alternatives to bridges for replacement of missing teeth without any loss of tooth structure. Optimal results can be achieved when an implant is placed between two natural teeth with healthy periodontium. This case report presents the management of a patient with missing maxillary right central incisor for whom the treatment of choice was placement of an osseointegrated implant supported prosthesis after regaining space to achieve a desirable esthetic result.

Keywords: Implant, Missing teeth, Space reopening.

Cone Beam Computed Tomography Evaluation of Postmenopausal Alveolar Bone Changes in Osteoporotic Women

[Year:2015] [Month:September-December] [Volumn:6 ] [Number:3] [Pages:28] [Pages No:65-68][No of Hits : 522]


ABSTRACT

Background: Osteoporosis is a metabolic bone disease commonly seen in elderly people and women. It is characterized by decreased bone mineral density leading to increased tendency to fracture. It has increased incidence in postmenopausal women. Dental radiographs can be used as a tool to identify the same. With the advancements in technology, cone beam computed tomography (CBCT) can be used for evaluation of alveolar bone changes and thus serve as a valuable predictor for osteoporosis.

Aim: To assess the alveolar bone changes in postmenopausal osteoporotic women using CBCT.

Objectives:

•   To assess pattern of bone loss as either horizontal or vertical in character.

•   To assess mandibular cortex index (MCI), mandibular cortex thickness (MCT), mental index (MI) and bone loss.

•   Thus to estimate the alveolar bone changes in postmenopausal osteoporotic women using CBCT.

Materials and methods: The present study was conducted in department of Oral Medicine and Radiology at Saveetha Dental College. Totally 91 women above 50 years of age were included in this study. Ethical committee clearance was obtained from the scientific committee of the university. Patients who were willing to replace their missing teeth by implant was evaluated by CBCT. Cone beam computed tomography used was ORTHOPHOS 3D, Sirona (Germany) at 90 Kvp, 14 mAS. MCI, MCT, MI and bone loss were assessed from the radiograph. The results obtained were subjected to statistical analysis using Statistical Package for Social Science (SPSS) software version 17.0 for Windows.

Results: In our present study, the mean age was 56 years. The endosteal margin was normal in 50%, mild in 19% and severe in 22% of the total subjects. There is no significant relationship in mental index between right and left side at the mental foramen region. The bone loss is angular in 46% of the subjects and horizontal in 45% of the subjects. There was a statistical significance between mental index and Mandibular cortical index which was done using one-way ANOVA (0.019). post hoc multiple comparison revealed statistical significance in MI’ of normal endosteal margin and MI’ of mild endosteal margin (0.021).

Conclusion: Thus to conclude, determining the rate of success in replacement of teeth especially using an implant, the density of bone is considered as an important factor. Further studies with larger samples will be helpful to establish a significant relationship between radiomorphometric indices and osteoporosis. Future studies comparing with gold standard dual energy X-ray absorptiometry (DEXA) can be done to standardise the correlation of radiomorphometric indices and osteoporosis.

Vascularized Interpositional Periosteal Connective Tissue Flap Technique to correct Soft Tissue Defect around Maxillary Anterior Implant

[Year:2014] [Month:January-April] [Volumn:5 ] [Number:1] [Pages:37] [Pages No:24-28][No of Hits : 3374]


ABSTRACT

The esthetic outcome of implant-supported restorations has become increasingly important, especially for single-tooth implants in the esthetic zone. Because of the morphologic alterations that occur following tooth extraction, augmentation procedures are often necessary before, during, or after implantation to achieve an esthetically pleasing result. There are many periodontal plastic surgery procedures available to esthetically reconstruct deficiencies in both hard and soft tissues; however each technique has its own limitation. A newer technique, vascularized interpositional periosteal connective tissue flap has been introduced as an alternative to these techniques which allows the clinician to perform large volume soft tissue augmentation in esthetic sites with a single procedure. In the present case report, long-term result of soft tissue augmentation with VIP-CT flap is presented were in peri-implant recession was noted as a complication.

Tilted Implant Concept for Full Mouth Immediate Loading Restoration

[Year:2014] [Month:January-April] [Volumn:5 ] [Number:1] [Pages:37] [Pages No:12-23][No of Hits : 3118]


ABSTRACT

Conventional techniques of full arch/full mouth implantation works on placement of implants and leaving them undisturbed for subgingival healing until they get osseointegrate into the jaw bone. These implants are uncovered after the subgingival healing of 3 to 6 months depending on various factors, such as bone density, implant dimensions, occlusal load, etc. and restored in function once the soft tissue has healed in next 3 to 4 weeks. The vertical ridge loss along with maxillary sinus pneumatization restrict the clinician to place adequately long implants into posterior maxilla without performing sinus augmentation procedures. Further, many patients who have the chronic sinus pathologies do not qualify to receive the sinus graft and refused by the dentists for the fixed implant prosthesis. Uncontrolled diabetics are also not good candidates for the sinus grafting. In the implant dentistry, such patients have simply been treated with the implant over dentures by avoiding posterior maxilla. In the similar fashion, the vertically resorbed posterior mandible has also been a big challenge for the implant dentists in the cases where the dentist find insufficient bone dimensions to place even shortest available implants above the mandibular canal. In implant dentistry, various procedures, such as onlay block grafting, nerve repositioning, etc. have been advocated to manage the resorbed posterior mandible. Such procedures are more invasive, require multiple surgical steps, elongate the treatment time and also cause the tissue morbidity to some extent. Moreover, the full mouth work is not very simple in most cases because most of edentulous patients do not step in with adequate bone dimensions in all four parts of the jaws to place implants with adequate dimensions. Conventional way of treating edentulous patients with full mouth implant supported fixed prosthesis may require placement of multiple number of implants, bone augmentation procedures, longer treatment span and multiple number of surgical steps. Thus, such techniques are not always comfortable and also affordable to the patients. In comparison to the posterior segments, anterior parts of the jaws offer the bone with larger volume and higher density which enables the dentist to place longer implants with higher initial stability by stabilising implant apices into the opposing cortices/ basal bone (nasal floor, mandibular symphysis).
In this tilted implant concept, the back implants are slanted distally to place the implant head at the second premolar or first molar position which enables to place longer implants, stabilizing their apices into the anterior higher density bone, and reduces the distal cantilever of the prosthesis. Total four implants are used in this technique where two straight implants are placed close to the midline and rest two implants are placed anterior to the maxillary sinus (in maxilla) or mental foramina (in mandible) which are slanted distally to reach the second premolar or first molar position. A 10 to 12 unit screw-retained metal to plastic (hybrid) splinted prosthesis is placed over these implants. Hence, it is a graft less implant placement procedure for restoring the edentulous jaws by tilting posterior implants for utilizing maximum amount of bone and stabilizing them into highest possible bone density. This facilitates an optimal support for an acrylic prosthesis that can be immediately fixed over the inserted implants to restore the esthetics and functions within few hours after the implant insertion surgery. This paper aims to explain the graft less approach for full arch immediate rehabilitation on 4 to 6 implants placed in one arch by smartly tilting the back implants to avoid vital structures, such as maxillary sinus and mandibular canal and stabilizing into the high density bone. This clinical study was done on total 80 implants to evaluate their success under the tilted positioning and immediate load conditions. The technique was performed on both diabetic and nondiabetic patients and no variation was found on the success rate between both the groups. None of the tilted implant got failed in 3 years follow-up but four implants got failed at anterior positions which immediately replaced with new implant placed at the adjacent position and restored in function. The mean values of bone loss relative to the implant platforms at 1 year follow-up were 0.8 mm for the maxilla and 0.5 mm for the mandible. The average bone loss for the maxilla and mandible respectively, at 3 years of follow-up were 1.3 mm. Thus, very promising results were found in this clinical study. Hence, the conclusion is that the tilted implant immediate function concept for completely edentulous patients has proven to be clinically effective technique, patient pleasing and applicable in various clinical situations where otherwise more invasive, complicated and expensive bone augmentation procedures would have been indicated.

Titanium Hypersensitivity: A Clinical Study

[Year:2014] [Month:January-April] [Volumn:5 ] [Number:1] [Pages:37] [Pages No:8-11][No of Hits : 2025]


ABSTRACT

Titanium implants are extensively used to replace the missing natural teeth in prosthodontics. However, allergic reactions to titanium in dentistry has not received its due attention. Literature reports sensitivity to titanium ranging from 0.6 to 5% of the general population. The allergic reactions in patients who are sensitive to titanium ranges from type I to IV with symptoms ranging from vague pain, skin rashes to implant failure. The aim of this study was to evaluate the presence of titanium allergy by anamnesis and examination of subjects using titanium dioxide 0.5% in patch test methodology. A sample size of four hundred healthy subjects with no previous history of immunosuppression were included. Titanium dioxide 0.5% concentration in petrolatum was used to conduct the patch test. A history of allergy to any other allergen was recorded as a part of the study. Under the limitations of this study, it was concluded that, titanium can induce hypersensitivity response in susceptible patients. From this study it was observed that the hypersensitivity reactions to titanium was 0.3% in all the subjects tested. It was also observed that the individuals with a prior history of allergy to other known allergens were more susceptible to allergic reactions to titanium. Limitations of the study was the absence of a wider age group of population for this study. Future research is recommended by considering a wider age group of population and a long-term follow-up of patients.

The Platform Switching Concept—A Myth or Fact: A Literature Review

[Year:2014] [Month:May-August] [Volumn:5 ] [Number:2] [Pages:48] [Pages No:55-59][No of Hits : 1763]


ABSTRACT

The peri-implant bone level has been used as one of the criteria to assess the success of dental implants. It is an important prerequisite for preserving the integrity of gingival margins and interdental papillae. Platform switching for maintaining periimplant bone levels has gained popularity among implant manufacturers over the last few years. Typically, crestal bone levels are situated 1.5 to 2 mm below the implant-abutment junction, dependent on various factors and there are several theories stating the reason for this phenomenon. Platform switching is a concept which aims at reduction of the crestal bone loss around the implants and involves the restoration of implants with smaller diameter abutments such that the implant abutment junction (IAJ) is horizontally repositioned inwardly and away from the outer edge of the implant platform. This review aims at summarizing the significance of platform switching.

Peri-implant Stress Analysis of Immediate Loading and Progressive Loading Implants in Different Bone Densities (D2 and D3): A Finite Element Study

[Year:2014] [Month:January-April] [Volumn:5 ] [Number:1] [Pages:37] [Pages No:1-7][No of Hits : 1538]


ABSTRACT

Aim: To analyze the peri-implant stress distribution in immediate loading and progressive loading implants in different bone densities (D2 and D3).

Materials and methods: A 3D finite element model of a mandibular section of the bone with a missing second premolar and a crown structure was used. Eighteen models were generated, eight were used for immediate loading and the remaining ten were of progressive loading. Of the eight models of immediate loading, four models each were used for D2 and D3 bone density types. Of the ten models used for progressive bone loading, five models each were used for D2 and D3 bone density types. A solid 4.2 × 10 mm screw type implant system (Replace Select RP, Nobel Biocare) was selected. The simulated crown consisted of metal coping of Nickel-Chromium alloy, porcelain and acrylic in few models. Axial and oblique loads were applied to the implant through the crown based on the loading protocols for immediate and progressive loading.

Results: Maximum stress was found in the cortical bone at the neck of the implant for both type of loading protocols except when there was no bone implant contact seen at initial stages of healing in immediate loading implants. Oblique occlusal forces show a significantly higher stress level as compared to axial loading forces.

Conclusion: Both loading conditions and bone density were found to be very important factor in the stress management in implant dentistry.

Natural Crown as Immediate implant Provisional Prosthesis

[Year:2014] [Month:January-April] [Volumn:5 ] [Number:1] [Pages:37] [Pages No:34-37][No of Hits : 1383]


ABSTRACT

Purpose: The purpose of this article is to describe a clinical case in which the patient’s failing tooth was extracted and with minute modifications the same crown was used as provisional’s after immediate implant placement. Esthetic single tooth implant placement using traditional two stage surgery or single stage in anterior maxilla is well-documented in literature. Several complications can occur in healing phase like loss of papilla, ridge resorption, tissue loss, etc. Patients own tooth with preserved crown architecture can be utilized as provisional as it may provide acceptable gingival esthetics, maintenance of interproximal contours , palatal adaptation, better tooth shape and preservation of both papilla.

Keywords: Immediate implants, Osseointegration, Socket, Esthetic outcomes, Single tooth replacement, Natural tooth.

Key Message: Preservation of hard and soft tissue architecture is very important during replacement of anterior single tooth especially in immediate implant restoration. Natural tooth can provide the best contours for preservation of tissue architecture. Thus a clinician should be careful during the surgery and can utilize patients natural tooth anatomy to preserve the papilla and interproximal height of bone which may be a better alternative to a fabricated plastic crown and better patient acceptance as temporary prosthesis.

Mandibular Implant-supported Overdenture as an Occlusion-guide for Maxillary Fixed Implant Prosthesis: A Clinical Report

[Year:2014] [Month:September-December] [Volumn:5 ] [Number:3] [Pages:31] [Pages No:109-113][No of Hits : 1307]


ABSTRACT

Unlike natural teeth, osseointegrated implants react biomechanically in a different fashion to occlusal load due to lack of the periodontal ligament. Hence, the dental implants may be more prone to occlusal overloading, which is often regarded as one of the potential causes for peri-implant bone loss and failure of the implant/implant prosthesis. Stability of the intercuspal position and reduction of lateral forces are important aspects when providing occlusal equilibration for implantsupported prosthesis. Multiple missing teeth in maxillary and mandibular arches with disturbed occlusal plane due to long-term edentulous condition and overeruption of remaining teeth into the edentulous spaces is the challenging clinical situation. This article describes the management of a patient with multiple missing teeth in both the arches with mandibular implant-supported overdenture and maxillary implant supported fixed prosthesis. The sequence of the treatment planning is highlighted to manage the complex situation to achieve the best predictable occlusion.

Temporary Anchorage Devices: Opening New Avenues in Orthodontics

[Year:2014] [Month:January-April] [Volumn:5 ] [Number:1] [Pages:37] [Pages No:v][No of Hits : 1101]


ABSTRACT

Temporary Anchorage Devices: Opening New Avenues in Orthodontics

Temporary anchorage devices (TADs) are the new rage in orthodontics today. All these years, orthodontists were accustomed to using teeth and auxiliary appliances, both intraoral and extraoral, to control anchorage. These methods are limited in that it is often difficult to achieve results commensurate with our idealistic goals. For more than 100 years, orthodontists have searched for ideal anchorage that fits two criteria: absolute resistance to unwanted tooth movement and independence from patient compliance. Conventional intra- and extraoral anchorage systems often fall short of providing absolute anchorage. This deficiency has spurred interest in skeletal anchorage systems, which appeal to practitioners because they have the potential to provide absolute anchorage and do not depend on patient compliance.

[Year:2014] [Month:May-August] [Volumn:5 ] [Number:2] [Pages:48] [Pages No:79-82][No of Hits : 1054]


ABSTRACT

Aim: To rehabilitate the patients with labially placed implants in maxillary anterior region to achieve optimal esthetics, emergence profile and function, along with the preservation of surrounding hard and soft tissue.

Background: Rehabilitation of a patient with maxillary anteriors with labially placed implant is always a challenge for a prosthodontist. If prefabricated abutments are used, labial contour would be too bulky that the implant-supported prosthesis would be out of arch.

Case description: This case series describes the use of patient specific abutments which are restored with zirconia prosthesis for optimal esthetics and function. This article also discusses the problems faced while rehabilitating such cases.

Conclusion: Unique surgical concepts are implemented for proper results to obtain ideal prosthetic restoration for missing teeth in esthetic regions. If surgical management is not chosen, prosthetically these cases can be managed by the use of customized abutments as described in this clinical report.

Clinical significance: Use of patient specific abutments as describe in this article resulted in satisfactory restoration in terms of function and esthetics in the critical maxillary anterior region.

[Year:2014] [Month:September-December] [Volumn:5 ] [Number:3] [Pages:31] [Pages No:99-104][No of Hits : 959]


ABSTRACT

Background: Periodontal pocket is a dynamic environment. Several interacting factors within this microenvironment play an important role in initiation and progression of periodontal diseases. Power of hydrogen (pH) is one of the important governing factor. Evidence suggests that pH of healthy gingival sulcus is between mildly acidic to neutral. A shift toward alkaline pH is observed in periodontal pocket which favors growth of gram-negative periopathogenic bacteria. Thus, the aim of the current study is to assess possible role of ascorbic acid in reversing subgingival alkaline pH and to determine optimum concentration of ascorbic acid for bacteriocidal effects.

Materials and methods: Subgingival plaque samples from 37 generalized chronic periodontitis patients were collected. Growth inhibition of periodontal pathogens with four different concentrations of ascorbic acid was examined anerobically after 48 hours. Photometric analysis and disk diffusion method were employed to quantify inhibitory effects.

Results: Evidence obtained by both the methods demonstrated possible bactericidal activity of ascorbic acid at 5 mg/ml. At this concentration, ascorbic acid showed stronger pH dependent inhibition toward gram-negative periopathogens.

Conclusion: Ascorbic acid can inhibit growth of periodontal pathogens at high concentration. Subgingival vitamin C administration could lead to prevention of plaque induced diseases. Due to its acidic nature, it should be used cautiously around teeth but recommended for maintenance of implants.

Keywords: Ascorbic acid, Chronic periodontitis, Antiplaque agent.

Comparative Evaluation of Dimensional Accuracy of Impression Techniques for Parallel Implants and Implants Placed with Angulation: An in vitro Study

[Year:2014] [Month:September-December] [Volumn:5 ] [Number:3] [Pages:31] [Pages No:92-98][No of Hits : 926]


ABSTRACT

Objective: This study aims to measure and compare the accuracy of various implant impression techniques in specimens with parallel implants placed at 90° to the horizontal plane and at 75°.

Materials and methods: Polyether medium body (3M ESPE Impregum) was selected as the material of choice. Two metal samples with three lab analogs placed in each were used as the master models. One had implants placed at 90° to the horizontal plane, and the other at 75°. Ten impressions were made each of stock metal tray, closed custom tray and open custom tray techniques. Photographs were taken and measurements were made using Adobe Photoshop software. Intragroup comparisons were done using the analysis of variance (ANOVA) and one way t-test. Intergroup comparison was done using two way t-test.

Results: All the techniques studied showed some distortion and the difference had no statistical significance. However, closed custom tray technique gave better results for the 90° specimen, and open custom tray technique gave better results for the 75° specimen.

Conclusion: Within the limitations of this study, it can be concluded that provided operator error is minimized and guidelines are followed, it may be possible to achieve impressions of similar accuracy regardless of technique used. However, it was impossible to achieve a level of exactness that would ensure a completely passive fitting prosthesis.

Comparison of Marginal Fit of Cast Implant Superstructure Pre- and Post-spark Erosion: An in vitro Pilot Study

[Year:2014] [Month:September-December] [Volumn:5 ] [Number:3] [Pages:31] [Pages No:105-108][No of Hits : 759]


ABSTRACT

Objective: To assess and compare the marginal fit of screw retained three unit implant superstructure, before and after spark erosion.

Methodology: An experimental model was prepared on which three unit screw retained implant superstructure on two implant analogs (cortex system) was fabricated which was then subjected to spark erosion. Sheffield test (one screw test) was carried out to determine the passivity. Assessment of vertical discrepancy was carried out using stereomicroscopic images of the superstructure and implant analog junction pre- and post-spark erosion with the help of image J analysis software.

Results: The implant superstructure fabricated with the conventional casting method were fitting actively on the implant analogs indicating a negative Sheffield test. However, following spark erosion passive fit was achieved. The marginal fit of the cast implant superstructure measured from a reference point on the superstructure to the implant analog margin was 4324.56 µm before spark erosion and 4046.57 µm after spark erosion.

Conclusion: Spark erosion technology with further research can be used to maximum efficiency to obtain passive fit of implant superstructure.

A Comparative Study to Assess the Quality of Bone following Ridge Augmentation with Autografts and Allografts: A Prospective Study

[Year:2014] [Month:September-December] [Volumn:5 ] [Number:3] [Pages:31] [Pages No:88-91][No of Hits : 745]


ABSTRACT

Aim: The aim of this study was to investigate the quality of bone at the augmented site in the anterior maxilla and mandible.

Materials and methods: Ten patients with inadequate bone for implant placement were included in this study. Of these 10 patients with inadequate bone volume, five were chosen to be treated with autogenous bone grafts (AT) and rest five patients were treated with freeze dried corticocancellous allografts (AL). Three months following grafting, biopsies of the grafted area were obtained using a 3 mm trephine bur and were histologically evaluated.

Results: Histological analysis revealed areas of new bone formation with thick trabeculae with lacunae containing osteocytes in the autogenous group, whereas the allograft group showed segments of necrotic bone with empty lacunae. Although, the AL group has an inherent advantage of avoidance of a secondary surgical site, showed decreased bone remodeling as compared to the autografts.

Conclusion: All the 10 patients underwent implant placement. The reports regarding the nature of bone obtained during implant placement clearly depicts a comparable histological variation at the grafted site.

Comparison of Micromotion around Basally Osseointegrated and Crestal Osseointegrated Implant in Mandibular First Molar Region: A Finite Element Analysis Study

[Year:2014] [Month:May-August] [Volumn:5 ] [Number:2] [Pages:48] [Pages No:39-42][No of Hits : 703]


ABSTRACT

Purpose of study: Crestal and basal implants are endosseous aids to create osseointegrated points of retention. These two types of implants are not only differentiated by the way they are inserted but also by the way the forces are transmitted. The purpose of this study is to compare the micromotion between two crestal and one basal implant-supported crown, when the mesiodistal space is 14 mm in mandibular 1st molar region.

Materials and methods: A three-dimensional finite element method was used to evaluate the micromotion in two osseointegrated crestal implants and one basally osseointegrated implant when the mesiodistal space is 14 mm in mandibular 1st molar region. The loads were applied according to cuspmarginal ridge relation. A total of 333 N and 645 N of load was applied to premolar and each molar respectively. The results were analyzed using Von Mises criteria.

Results: The results of the comparison of crestal and basal implant to replace mandibular first molar demonstrated that micromotion in crestal implant (14.545) was less than basal implant (36.031).

Conclusion: Thus, within the limitations of this study, it can be concluded that the use of two crestal implants to replace a missing mandibular first molar with mesiodistal edentulous space of 14 mm is a preferable option as compared to basal implant to replace a missing mandibular molar.

Keywords: Basal implant, Crestal implant, Micromotion.

Short Dental Implants: Its Rationale for Use

[Year:2014] [Month:May-August] [Volumn:5 ] [Number:2] [Pages:48] [Pages No:50-54][No of Hits : 698]


ABSTRACT

Atrophy of alveolar bone in the posterior part of the mouth is routinely encountered in clinical practice. The present treatment modality to replace the missing teeth with an implant-retained fixed partial denture includes sinus bone grafting in the maxilla and onlay bone graft in the mandible. This type of treatment is invasive and requires more time and cost. Short dental implants are used as an alternative treatment modality to bone grafting procedures. Short implants could provide equivalent results to those of longer implants if certain principles are followed. The present article reviews the current literature on the use of short implants and discusses the biomechanical considerations when using short implants.

Rehabilitation of a Patient with Screw-retained Milled Titanium Hybrid Prosthesis in the Mandibular Arch and Immediate Implant Placement in the Region of Maxillary Canine followed by Connective Tissue Graft and Immediate Provisionalization

[Year:2014] [Month:May-August] [Volumn:5 ] [Number:2] [Pages:48] [Pages No:83-87][No of Hits : 667]


ABSTRACT

The continuous resorption of the edentulous mandible is the most common cause for the patients not being satisfied with conventional dentures. With the advent of dental implants, various removable and fixed options can be provided to the patient for better function, retention, esthetics and phonetics. The mandibular implant-supported hybrid prosthesis ia a viable prosthetic option as it fixed for the patient and removable for the clinician. The passive fit of a hybrid prosthesis is a pre-requisite for a successful prognosis, which can be achieved using the newer technology like computer-aided design and computer-aided manufacturing (CAD-CAM) milled titanium frameworks. The use of connective tissue graft to enhance soft tissue bulk around implants helps the clinician provide esthetically appealing outcomes. Immediate loading of the implants is the most preferred option for patients who are esthetically very conscious. Its provisionalization using screw-retained prosthesis ensures a stable peri-implant health as the extruded cement can be eliminated extraorally. This article presents the fabrication of mandibular implant-supported hybrid prosthesis with CAD-CAM milled titanium framework and connective tissue around immediately placed implant with screwretained provisional prosthesis.

Immediate Implant Placement and Provisionalization: Optimizing Esthetics and Function

[Year:2014] [Month:May-August] [Volumn:5 ] [Number:2] [Pages:48] [Pages No:72-78][No of Hits : 587]


ABSTRACT

Esthetic replacement of tooth in the anterior maxilla is one of the most critical demands of any patient seeking tooth replacement. One of the major current challenges is oral rehabilitation after tooth loss, due to fracture. Esthetic and functional results, together with periodontal health, predict success and prognosis. Implant dentistry provides the solutions for the placement of osseointegrated screw-retained implants or cemented prostheses to replace missing teeth. Careful use of provisional prostheses preserves the harmonious architecture of gingival tissues and affects final treatment results positively. This study describes series of three clinical cases of root fracture of maxillary anterior teeth, which had been previously endodontically treated. The teeth were extracted, immediate implants were placed and the provisional prostheses were fabricated and immediately loaded. The use of an immediate provisional restoration is a viable technique that has good esthetic and functional results and preserves gingival architecture and provides excellent esthetic result for the patient.

Esthetic Rehabilitation with Immediate Implants in a Compromised Situation

[Year:2014] [Month:May-August] [Volumn:5 ] [Number:2] [Pages:48] [Pages No:60-62][No of Hits : 549]


ABSTRACT

The end goal of prosthetic replacement of teeth following tooth loss is to provide a functional restoration that is harmonious with the remaining natural dentition. To achieve this goal, hard and soft tissues need to be present in adequate volume and quality. An increasingly common strategy to preserve bone and reduce treatment times includes the placement of dental implant into a fresh extraction site. Resorption of the alveolar bone is common after the extraction and presents a clinical challenge to ideal implant placement, especially in the esthetic zone. In order to preserve the extraction socket dimension, immediate implant placement at the time of extraction has been proposed. The technique involves atraumatic extraction of the tooth followed by implant placement. Voids between the implant and the socket walls are filled with a particulate bone graft material. This article describes one such case of immediate implant placement and prosthodontic rehabilitation of a young patient following traumatic loss of natural teeth.

ABSTRACT

‘This is no longer Your Father’s Implant Dentistry!’

The axiom ‘I placed the implant where the bone was’ is a dated concept in implant dentistry today, and no longer accepted as the ‘norm’. Osseous grafting has become an integral part of implant treatment, allowing ideal implant placement without the compromises we accepted in the past related to where the residual bone remained.

Implants in Diabetic Patients

[Year:2013] [Month:January-April] [Volumn:4 ] [Number:1] [Pages:53] [Pages No:30-35][No of Hits : 6404]


ABSTRACT

Diabetes mellitus has become a public health problem because of its increased prevalence all over the world. Diabetes is associated with altered glucose homeostasis. Diabetics have impaired wound healing and impaired bone metabolism. Safely managing the patient with diabetes requires effective communication among multiple health care providers. Although implants are increasingly used in healthy patients, their appropriateness in diabetic patients is less equivocal. Perhaps surprisingly, the evidence of their efficacy in these groups of patients is quite sparse. It is known to impair healing which increases the risk of tissue necrosis and infection. Improvement in glycemia levels in previous studies are well suited to dental implant surgery with acceptable degree of predictability. This article review the implications of diabetes and glycemic control for the prognosis and evolution of dental implants.

A Minimally Invasive Sinus Augmentation Technique using a Novel Bone Graft Delivery System

[Year:2013] [Month:May-August] [Volumn:4 ] [Number:2] [Pages:40] [Pages No:78-82][No of Hits : 6067]


ABSTRACT

A variety of surgical techniques and materials have been developed to increase the vertical bone height in the posterior maxilla. Minimally invasive crestal approaches for the elevation of the floor of the sinus using a crestal approach have been recently reported to minimize adverse events associated with the use of the osteotome technique for indirect sinus lift. The aim of this study is to report a surgical improvisation that minimizes risks associated with sinus floor elevation using a crestal approach and simplifies the clinical procedure. The technique is based on the use of a viscoelastic calcium phosphosilicate alloplastic putty (CPS putty) bone substitute that can be delivered utilizing a unique cartridge delivery system.
CPS putty not only acts as a 'protective cushion' thanks to its physical properties, but also provides hydraulic pressure to lift the Schneiderian membrane when used in conjunction with the cartridge system. This approach minimizes risks of benign paroxysmal positional vertigo or mechanical perforations of the Schneiderian membrane associated with the traditional osteotome technique.

Immediate Placement Implant in Fresh Extraction Socket: A Clinical Study of Seven Cases

[Year:2013] [Month:January-April] [Volumn:4 ] [Number:1] [Pages:53] [Pages No:7-15][No of Hits : 5755]


ABSTRACT

Aims and objectives: To reduce the prolonged waiting period post tooth extraction for rehabilitation with implants. This study was carried out to determine the outcome of implants placed into fresh extraction sockets with the simultaneous use of particulate bone graft. Patient response to rehabilitation with immediate placement single tooth implants was monitored clinically and radiographically.

Materials and methods:Among seven patients, with the average age of 28 years were treated for single tooth replacement in fresh extraction sockets in the esthetic zone by means of 2 stage immediate placement of implant. Bioactive glass particulate bone graft was used as bone graft material. Reason for teeth loss was caries, trauma and internal resorption. All patients were followed clinically and radiographically for 1 year after loading of implant.

Results: Follow-up was done after stage I surgery (placement of implant) for pain, soft tissue dehiscence, inflammation, altered sensation at site of implant placement monthly for 4 to 6 months. After giving final prosthesis, patients were evaluated for bleeding index (Muhlemann and Son), plaque index (Turesky- Gilmore- Glickman) gingival index (Loe and Silness), marginal bone loss (parallel cone technique using IOPA) with follow-up at 6th and 12th months. All the implants were osseointegrated at the time of abutment placement. Radiographic examination showed only slight marginal bone around the implants.

Conclusion:Hence, implants can be placed successfully in fresh extraction socket using bioactive glass (perioglass) particulate bone graft material to fill gap between implant and bone through a submerged (2 stage) surgical technique.

Osseointegration of Zirconia (Y-TZP) Dental Implants: A Histologic, Histomorphometric and Removal Torque Study in the Hip of Sheep

[Year:2013] [Month:May-August] [Volumn:4 ] [Number:2] [Pages:40] [Pages No:55-62][No of Hits : 3943]


ABSTRACT

Objectives: The purpose of the present study was to demonstrate the biocompatibility and rigid osseointegration of a zirconia (Y-TZP) dental implant with acid-etched surface.

Materials and methods: Eight zirconia (Y-TZP) implants (CeraRoot, Barcelona) were inserted in the hip of an adult sheep. The animal was sacrificed after 2 months. Four implants were used for histology and histomorphometric analysis, and the other four implants were used for removal torque test (RTQ).

Results: The histological evaluation showed a direct bone to implant contact (BIC) with no signs of inflammatory or foreign body reaction. The histomorphometric analysis values ranged from 79.5 to 79.9% of BIC. The RTQ showed values ranging from 75 to 83 Ncm.

Discussion: In this animal study, the biocompatibility of CeraRoot zirconia (Y-TZP) implants was demonstrated with the histologic observations of healthy bone tissue in direct contact with the zirconia (Y-TZP) implant surface. Moreover, the histomorphometric analysis and the RTQ confirmed a rigid fixation of the implant within the bone. Comparative studies with acid-etched titanium implants are needed to further evaluate the characteristics of CeraRoot zirconia dental implants.

Influence of Occlusal Forces on Stress Distribution on Preloaded Dental Implant Abutment Screws: A Finite Element Analysis Study

[Year:2013] [Month:January-April] [Volumn:4 ] [Number:1] [Pages:53] [Pages No:16-23][No of Hits : 3593]


ABSTRACT

Purpose:The aim of the study is to determine stress distribution on preloaded implant-abutment screws in three different implant systems under simulated occlusal loads.

Materials and methods:Three abutments to implant internal hex joint systems were simulated by using the 3-dimensional finite element analysis; (1) Nobel Biocare replace tapered (2) Uniti (3) Lifecare self-threaded tapered cement retained abutments. Thermal load and contact analysis were used to simulate preload resulting from the torque in implant screw joint assemblies. The simulated preload implants were then loaded with three static occlusal loads (10N horizontal; 35N vertical; 70N oblique) onto the crown into the implant complex.

Results: Under preload and static occlusal forces, maximum Von-Mises stresses were concentrated at the lower portion of abutment for all systems. Maximum stresses were concentrated at lower threaded portion of abutment screw in Nobel Biocare, Uniti but in Lifecare system, stresses were concentrated at the middle threaded portion. Maximum stresses were concentrated at middle threaded portion of implant in Nobel Biocare, Uniti but at the upper threaded portion in Lifecare. Stresses increased under static occlusal forces in abutment screw in Nobel Biocare and Uniti but were more under oblique forces. In Lifecare stresses decreased under horizontal forces and increased in vertical and oblique forces.

Conclusion:Although, an increase or decrease was demonstrated for the maximum calculated stress values in preloaded screws. After occlusal loads, these maximum stress values were well below the yield stress of abutment screw systems tested.

Keywords: AStress distribution, Static occlusal loads, Von-Mises stresses.

Edlan-Mejchar Vestibular Deeping in a Failing Implant Case

[Year:2013] [Month:September-December] [Volumn:4 ] [Number:3] [Pages:34] [Pages No:108-111][No of Hits : 3403]


ABSTRACT

Necessity of the width of keratinized mucosa around implants has been a topic of much controversy. There have been reports both supporting and against the idea. This is a case report describing an EdlanMejchar vestibular deepening procedure done with respect to a mandibular anterior failing implant. The procedure helped in increasing the keratinized mucosa around the implant thus rendering a harmonious soft tissue for healing of the peri-implant mucosa. Based on the findings of the present case it can be concluded that keratinized mucosa around the implant is detrimental in the success of the implant.

ABSTRACT

Purpose:The phenomenon of developing a certain tactile sensibility through osseointegrated dental implants is called osseoperception. Active tactile sensibility can be tested by having the subject bite on test bodies. The aim of the study was to assess the active tactile sensibility of osseointegrated single tooth dental implants according to psychophysical method of constant stimuli.

Materials and methods:Twenty subjects (10 male and 10 female) with single tooth implants located in the posterior region with natural, healthy antagonistic teeth were included in the study. Ten implants were located in the maxilla and 10 in the mandible. The subjects were also divided into two age groups 30 to 40 years and 40 to 50 years, and the active tactile perception was studied according to the psychophysical method of constant stimuli.

Results: The active tactile perception of osseointegrated single tooth dental implants with natural healthy antagonist revealed a threshold ranging between 24 ± 8 µ. The active tactile perception of healthy natural tooth with natural healthy antagonist revealed a threshold ranging between 12 ± 4 µ. No statistically significant results were found between different age groups (30-40 years age group and 40-50 years age group). The threshold for tactile perception was found to be similar in both male and female subjects. No statistical significance was found in the threshold between different implant locations (maxilla and mandible).

Conclusion:Active tactile sensibility of implants with natural antagonistic teeth is similar to that of teeth. Implant-supported prosthesis restores jaw function more appropriately, with improved psychophysiological discriminatory ability.

Tooth Implant Connection

[Year:2013] [Month:September-December] [Volumn:4 ] [Number:3] [Pages:34] [Pages No:95-98][No of Hits : 2401]


ABSTRACT

The aim of this study was to carry out a review of all available literature addressing the tooth-implant connection and evidencebased understanding of the management of tooth-implantretained restorations.
Connecting teeth to osseointegrated implants presents a biomechanical challenge. This is due to the implant being rigidly fixed to the bone and the tooth being attached to the bone with a periodontal ligament. This ligament acts as a shock absorber and allows teeth to take less stresses than implants. This leads to biomechanical failure of implants over a period of time.
In order to overcome this problem, various connection types such as rigid and nonrigid have been proposed. However, the mechanism of attachment and the perceived problem of the differential support provided by the implant and the tooth have been discussed by many authors, and the ideal connection type is still controversial.
Literature published was searched through science direct, Google and PubMed. The most relevant articles were evaluated, selected and systematically analyzed.

Keywords: Dental implants, Fixed partial denture, Intrusion, Tooth and implant connection.

ABSTRACT

Background: According to previous studies, persons wearing implant-retained prostheses may create bite forces comparable to those possessing natural dentition and it has been suggested that the risk for combination syndrome increases in persons wearing mandibular implant-retained prostheses opposed to maxillary complete dentures.

Aim: This article presents the fabrication of a maxillary conventional complete denture opposing a mandibular implant retained fixed prosthesis and evaluates the changes in the edentulous maxilla and prostheses over a period of 2 years.

Case description: A comprehensive treatment included a conventional removable complete denture for the upper arch and a six implant supported fixed prosthesis for the lower arch.

Conclusion: This article reports on the fabrication of a maxillary conventional complete denture opposing a mandibular implantretained full fixed prosthesis. Occlusion and articulation were found to be good over a period of 2 years. Retention and stability were found to be good uptill the 18 months review and moderate at the 24 months review.

Clinical significance: To preserve anterior maxillary bone, a balanced occlusal concept has been recommended for implantretained mandibular prostheses opposing a tissue supported conventional maxillary complete denture. In this case, the patient was rehabilitated with a balanced occlusion without anterior tooth contact in maximal intercuspation.

[Year:2013] [Month:January-April] [Volumn:4 ] [Number:1] [Pages:53] [Pages No:44-46][No of Hits : 2312]


ABSTRACT

Implants are fast becoming an integral part of modern dentistry. It is the only treatment modality where additional abutments can be created for improving the esthetics and function. When diagnostic protocol involves both the surgeon and the prosthodontist, the biomechanical, technical and esthetic compromises are circumvented. Careful planning, evaluation of all the diagnostic aids, mock wax up and using a surgical guide helps to accurately locate the implant fixture regarding the depth and angulation which is critical to the esthetic and biomechanical success of the prosthesis.The clinical case depicted here is an illustration of how difficult it becomes to restore the case when the fixtures are placed in incorrect location and/or angulation.

ABSTRACT

Implant retained over denture (IRO) is a satisfactory treatment modality for edentulous patient with problems with their lower denture. There are good reasons why this treatment should be selected in preferences to using tissue supported dentures. There are certain rules that provide a method to control the mechanical environment, addressing factors effecting implant and prosthesis longevity, including magnitude of forces, resistance of prosthesis against theses forces, and the biology of bone and its ability to respond to loading environments.

Materials and methods: Ten edentulous patients were selected for implant retained prosthesis for the mandible, with minimum four implants in parasymphysis region and prosthesis were delivered after period of 3 months.

Conclusion: Certain important points needs consideration for successful prosthesis and its longevity.

Keywords: Implant, Overdenture, Mandible, Planning, Edentulism.

Key message: The report provides simple rules for treatment planning in implant therapy in edentulous mandible with minimum of four implants that both acknowledge and control the mechanical environment. This influences the success of both the end osseous dental implants and the prosthesis and can offer lasting success for treatment of edentulous mandible.

Synergy between 3D Models and Tissue Engineering to Optimize Sinus Lift, Implant Placement and Immediate Loading in Partially Edentulous Patients

[Year:2013] [Month:January-April] [Volumn:4 ] [Number:1] [Pages:53] [Pages No:36-43][No of Hits : 2014]


ABSTRACT

Tissue engineering is a clinical approach toward the development of dynamic molecular delivery that can restore and improve regeneration. The 3D models and regenerative principles applied during implant guided dental surgery open new approaches for tissue constructs favoring sinus lift and implant placement.

Purpose: The aim of the present clinical study was to determine evidence that synergy between 3D models and bone regeneration utilizing autologous fibroblast growth factor (FGF) and growth factors matrices mixed with demineralized freezedried bone allograft (DFDBA) particles optimize tissue engineering for immediate dental implant placement and loading during sinus lift procedure.

Materials and methods: Twelve endo-osseous implants were placed into residual crestal bone (5.0 ± 0.15 mm). A minimal invasive osteotome Summer's technique was performed in combination with autologous FGF matrices mixed with FDBA particles. Soft tissue height and width were measured at baseline, 1, 3 and 6 months. Engineered bone surrounding implants was analyzed through 3D metric models for volume and contact interface from baseline to 6 months.

Results: Healing was uneventful. The surgical guide and the osteotome technique significantly contribute to the initial implant stability. Gingival soft tissue improves in color and contour. Soft tissue height and width both increased from baseline to 6 months. At 1 month, soft tissue height (STH) increase was 2.55 ± 0.30 mm (CI 95%—p = 0.001), and soft tissue width (STW) gain was 1.50 ± 0.50 mm (p = 0.001—CI 95%). At 3 months, STH increased to 3.12 ± 0.50 mm and STW gain was 2.40 ± 0.40 mm (p = 0.001—CI 95%). At 6 months, these values remained stable. Implant sites receiving autologous FGF matrices mixed with DFDBA exhibited a BV gain of 0.47 ± 0.10 cm3—bone fill averaging 100% at 6 months (p = 0.001).

Conclusion: The osteotome Summer`s technique was a predictable technique to increase bone volume. Autologous FGF matrices mixed with DFDBA favors 3D scaffold enhancing bioguided soft tissue gain and bone engineering at implant interface. Sinus membrane perforations were favorable controlled. Guided dental surgery and three-dimensional metric applications improve surgical placement, mechanical support, clinical performance and patient cost/benefit satisfaction. Further studies with a larger sample are needed to enhance the statistical significance of our clinical findings.

Lateral Sinus Augmentation: A Simplified Safer Approach

[Year:2013] [Month:May-August] [Volumn:4 ] [Number:2] [Pages:40] [Pages No:83-89][No of Hits : 1816]


ABSTRACT

Enlargement of the maxillary sinus often precludes implant placement in the posterior quadrant without augmentation to create increased bone height to stabilize the implant fixtures and provide load handling following restoration. Maxillary sinus augmentation has been a technical challenge due to the potential for tearing of the Schneiderian membrane during lateral window formation. This article will discuss and review unique instrumentation for a safer simpler approach to lateral window maxillary sinus augmentation.

Sinus Augmentation Utilizing Calcium Phosphosilicate Biomaterial Followed by Delayed Implant Rehabilitation: Radiological and Clinical Analyses

[Year:2013] [Month:September-December] [Volumn:4 ] [Number:3] [Pages:34] [Pages No:102-107][No of Hits : 1787]


ABSTRACT

The direct sinus lift approach is a well-established technique for implant placement in the deficient maxilla. The need to provide efficacious treatment to patients while minimizing procedure-associated morbidity lead to the introduction to bone substitutes as alternative to autogenous bone grafting for bone augmentation in the sinus.
Calcium phosphosilicate biomaterial is the form of morsels that have been recently introduced for use in oral surgery. The osteostimulative properties of this biomaterial makes it an excellent bone substitute for indications that have been traditionally treated with autogenous bone graft.
A case is presented where implant rehabilitation was planned in left maxillary posterior region with pre-existent significant pneumatization of the sinus. Under local anesthesia direct sinus lift technique was employed. The results were highly satisfactory showing regeneration up to approximately 13 mm of bone height that allowed successful implant placement of appropriately sized implant fixtures.
The present case-study is a proof-of-principle study of the efficacy of morsels in direct sinus lift. Use of morsels for sinus augmentation provides successful outcomes with minimal morbidity for the patient and significant decrease in chair-side time that would be required for harvest of an autograft.

Mesiodistal Bone Loss of Fresh Socket Placed Implants and Delay Placed Implants at the Anterior of the Maxilla

[Year:2013] [Month:May-August] [Volumn:4 ] [Number:2] [Pages:40] [Pages No:63-67][No of Hits : 1700]


ABSTRACT

Introduction: Immediate implant placement in fresh extraction sockets provides the advantage of shorter treatment time along with minimizing the number of surgical interventions.

Materials and methods: Subjects were studied in two groups: in group 1, subjects received a fresh socket placed implant at the anterior of the maxilla and in group 2, a delay placed implant was inserted at the same site. The mesial and distal marginal bone level was measured using parallel technique radiography in time 0, 12, 24 and 36 months after loading.

Results: Seventy subjects were studied in two groups. Analysis of the data using a repeat measure test demonstrated the similar bone loss patterns between two groups. Time has a significant effect on bone loss in time 1, 2, 3. The amount of bone loss increased as time passed after loading time. Comparison of bone loss in both groups demonstrated that the amount of bone loss in the central site was more than the lateral site in three measurement times for the group 2 but in the group 1, a significant difference was not observed.

Conclusion: Comparison of marginal bone loss in fresh socket placed implants and delay implants did not show a significant difference. Also a continuous bone resorption was observed over the time in the both groups. It may be needed to investigate other success criteria in fresh socket placed implants for making an appropriate treatment plane.

Lateral Sinus Augmentation: A Safer Technique

[Year:2013] [Month:September-December] [Volumn:4 ] [Number:3] [Pages:34] [Pages No:122-128][No of Hits : 1596]


ABSTRACT

The posterior maxilla presents with a common problem clinically following tooth extraction or crestal bone loss resulting in loss of osseous height sufficient to place implants. Resorptive patterns in some patients along with sinus enlargement result in minimal bone that can accommodate implant placement. Maxillary sinus augmentation over the past 18 years with various bone graft materials has become routine treatment. Numerous studies have reported highly successful implant survival rates when placed into the augmented sinus. The most common complication of the lateral sinus elevation approach is typically tearing of the Schneiderian membrane which could allow for bacterial contamination or loose particles to gain access to the sinus cavity. A safer lateral window approach sinus augmentation procedure will be discussed using specialized safe cutting end drills with vertical stoppers for osseous window formation and subsequent membrane elevation.

[Year:2013] [Month:September-December] [Volumn:4 ] [Number:3] [Pages:34] [Pages No:118-121][No of Hits : 1313]


ABSTRACT

Background: Augmentation of the bone is done to create the sufficient bone volume for ideal implant placement. This case report presents the effective augmentation of the socket using corticocancellous graft and AlloDerm.

Methods: Failing 47 was extracted. Socket had a severe buccal dehiscence extending and a thin keratinized mucosa around. After through debridement, socket walls were decorticated and corticocancellous graft and allograft GBR was tacked over the socket. Mucoperiosteal flap was sutured with 5-0 nylon sutures (Ethicon) Bone core biopsy was done for histologic assessment and site was restored with screw-retained implant prosthesis.

Results: Histologic assessment revealed ingrowth of new bone around the bone graft. Stable soft and hard tissue results have been seen with 2 years follow-up of the case.

Conclusion: Results indicated that ridge preservation using corticocancellous graft and AlloDerm prevented the ridge resorption and helped in enhancement of bone fill and soft tissue volume.

Quo Vadis—Implant Dentistry?

Quo Vadis is a term that gained popularity with the 1951 film of the same name starring Robert Taylor and Deborah Kerr and, in the 1980s, inspired a line of footwear by Bata. The term literally means 'Where are you going' and, at this point in time, it seems pertinent to ask this of the science of implant dentistry.

Evolution of External and Internal Implant to Abutment Connection

[Year:2012] [Month:September-December] [Volumn:3 ] [Number:3] [Pages:48] [Pages No:122-129][No of Hits : 18577]


ABSTRACT

A study of the implant to abutment connection is of paramount importance as it is the primary determinant of the strength and stability of the implant supported restoration, which in turn determines the restoration’s prosthetic stability. Traditionally, the Branemark's external hexagon has been widely used but its significant complications like abutment screw loosening, rotational misfit at implant-abutment interface and microbial penetration have led to modification of the external hexagon and the development of the internal implant-abutment connections. This review describes the various implantabutment connections that have evolved overtime from the traditional external hexagon.

Surface Modifications for Endosseous Dental Implants

[Year:2012] [Month:September-December] [Volumn:3 ] [Number:3] [Pages:48] [Pages No:116-121][No of Hits : 16909]


ABSTRACT

Since, the inception of the vast field of implantology in 1969, this method still remains a popular and reliable one for the replacement of missing teeth. Over the years designs by various researchers have been introduced as well as modifications to the surface of the titanium being used. Characteristics of titanium implant surfaces have been modified by additive methods (e.g. titanium plasma spray) to increase the surface area and provide a more complex surface macrotopography. Subtractive methods (e.g. blasting, acid etching) have also been used to increase the surface area and to alter its microtopography or texture.
The field of surface modifications is vast and constantly evolving to keep up with technology, incorporation of biologically active substances, drugs and growth factors is an area of ongoing research. This review article entails the various surface modifications and the latest surface treatments that the world of oral implantology has to offer.

Mind the Gap: The Platform Switching Concept

[Year:2012] [Month:September-December] [Volumn:3 ] [Number:3] [Pages:48] [Pages No:130-132][No of Hits : 10052]


ABSTRACT

After exposing a submerged implant to the oral environment, bone loss occurs downwards along the implant body and stops at some predefined position. A current area of hot debate is the significance of the implant abutment interface and its influence on crestal bone level in relation to the first thread. In recent years, the microgap which exists at the connection between the implant body and the restorative abutment has been implicated. Recently, it has been suggested that the presence and position of the microgap may not be the principal cause of bone resorption phenomenon, but instead that it is due to the relative diameters of the abutment and the implant platform. It appears desirable to incorporate features into implant design which reduce microleakage or limit its effects. A tapered implant abutment creates a microseal and the hermetic seal produced eliminates the microgap preventing the passage of bacteria. Hence platform switching may limit or confine the effect.

Maxillary Sinus Lift Up: An Indirect Approach for Implant Placement in Posterior Maxilla

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:101-104][No of Hits : 9541]


ABSTRACT

The posterior maxilla presents several challenges to the implantologist. Implant dentistry has become an excellent treatment modality since its inception into the modern era of dentistry. When patients present with deficient alveolar ridges, it could jeopardize the application of implant dentistry. This problem is especially magnified in the posterior maxilla where ridge resorption and sinus pneumatization are often encountered. The procedure of choice to restore this anatomic deficiency is maxillary sinus floor lift up. The purpose of this case report is to bring forward such technique which prevents perforation of sinus lining during implant placement by doing the sinus lifting with indirect approach through alveolar crest. The indirect approach for sinus lift is less invasive and less complex and therefore a better alternative for such cases.

Alveolar Ridge Preservation Utilizing the 'Socket-Plug' Technique

[Year:2012] [Month:January-April] [Volumn:3 ] [Number:1] [Pages:61] [Pages No:24-30][No of Hits : 8789]


ABSTRACT

It is proven that after every extraction of one or more teeth the alveolar bone of the respective region undergoes resorption and atrophy. Therefore ridge preservation techniques are often employed after tooth extraction to limit the volume of the alveolar bone that is going to be resorbed. There are many benefits in employing a flapless ridge preservation procedure. The purpose of this article is to present the literature concerning flapless ridge preservation techniques with collagen plugs for occlusion of the socket. The term ‘socket-plug technique’ is introduced to include these techniques. The basic steps of the ‘socket-plug technique’ are:

  • Atraumatic tooth extraction
  • Preservation of soft tissue architecture with the flapless technique
  • Placement of the appropriate biomaterials in the extraction site
  • Collagen plug stabilization
  • A case is presented to illustrate the steps used in this technique.

Immediate Implant Placement in Maxillary Molars using Septa Dilatation with Threaded Expanders: 3 Years Follow-up and use of the Technique in Complex Cases

[Year:2012] [Month:September-December] [Volumn:3 ] [Number:3] [Pages:48] [Pages No:138-145][No of Hits : 5921]


ABSTRACT

Challenges often confront the surgeon when placing implants into the maxillary arch due to lower bone density. This can be further complicated due to the proximetry of the maxillary sinus especially when immediate implant placement is contemplated at time of extraction. This article will review the use of rotary osteotomes for improvement of bone site density and quality to allow implant placement in the maxillary posterior.

Zirconia Abutments in Implant Dentistry

[Year:2012] [Month:January-April] [Volumn:3 ] [Number:1] [Pages:61] [Pages No:39-42][No of Hits : 5200]


ABSTRACT

Esthetic parameters have become integral aspects in defining success and failure of an implant. All-ceramic abutments have started to play a major role in achieving an esthetically successful result. The material itself, however, is not the exclusive determinant for esthetic success. It is the appropriate design and proper handling of the material and the abutment that enables the clinician to achieve esthetic outcomes that were not possible with traditional metal alloys. The focus of this systematic review was to assess the published data on the zirconia dental implant abutment.

Piezosurgical Mandibular Ridge Expansion for Immediate Implant Placement

[Year:2012] [Month:January-April] [Volumn:3 ] [Number:1] [Pages:61] [Pages No:47-50][No of Hits : 4898]


ABSTRACT

Edentulism of a long standing nature leading to severe alveolar ridge atrophy with a resultant thin ridge often pose a great challenge to the clinicians for rendering implant supported prosthesis in that region. The ideal treatment in such a scenario will be the ridge expansion procedure for achieving an increase in the available bone volume at the implantation site. The space thus created between the bony walls renders an ideal regenerative and implant-integrating condition. The use of a piezosurgical device for performing a piezoelectric alveolar ridge expansion procedure permits a precise and tactile controlled osteotomy facilitating implant placement in anatomic situations previously impossible in a single stage surgical procedure. This case report demonstrates the ease of mandibular ridge splitting with the use of piezosurgical principle facilitating immediate implant placement in a severely resorbed thin edentulous alveolar ridge.

Alveolar Ridge Preservation with β-TCP Graft and Platelet-Rich Fibrin

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:96-100][No of Hits : 4784]


ABSTRACT

Guided bone regeneration (GBR) procedures, employing nonvital bone grafting materials and membranes, were developed to counteract the significant resorption of alveolar bone following tooth extraction. Alloplastic graft material, consisting of pure phase of β-tricalcium phosphate (β-TCP) in the preservation of ridge volume after tooth extraction and before dental implant placement, is a well-accepted procedure. The healing potential of platelet growth factors has generated interest in using plateletrich fibrin (PRF) in ridge preservation procedures. In the present case report, β-TCP bone graft was combined with PRF utilizing the principles of guided bone regeneration to build the damaged edentulous ridge to receive dental implant.

Periimplantitis

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:71-76][No of Hits : 4510]


ABSTRACT

Periimplantitis is an inflammatory process that affects both the hard and soft tissues around a functional implant and results in marginal bone loss, which may eventually lead to loss of osseointegration. Bacterial infection is known to play a major role in the etiology of this disease although there remains some debate as to whether this is a host susceptibility related or implant surface phenomenon or both. Prevention of these infections is a major factor when treating patients with implants, particularly, if they present with a periodontal disease. This article presents the etiology, pathogenesis and treatment of periimplantitis that has been seen to yield favorable results.

Ridge Preservation done Immediately following Extraction using Bovine Bone Graft Collagen Plug and Collagen Membrane

[Year:2012] [Month:January-April] [Volumn:3 ] [Number:1] [Pages:61] [Pages No:8-16][No of Hits : 4284]


ABSTRACT

Background and objectives: Socket augmentation at the time of extraction is an attempt to reduce crestal bone loss, encourage socket fill, minimize horizontal ridge resorption, and ultimately reduce or eliminate the need for further ridge augmentation. The aim of this study is to evaluate the efficacy of naturally derived bovine hydroxyapatite, resorbable collagen membrane and collagen plug in ridge preservation as compared to an unassisted naturally healing extraction site.

Methods: Twenty-two systemically healthy patients participated in the study. Seventeen completed the study and were included for analysis. One site in each patient was treated as control site and only received an atraumatic extraction procedure while the other site was subjected to a ridge preservation procedure following atraumatic extraction. Parameters, such as loss of ridge width, loss of ridge height were measured clinically, with the help of occlusal stents on pre- and postoperative models and radiographically with the help of AutoCAD software. These measurements were made at baseline as well as 6 months post-operative.

Results:The treatment modality resulted in significant reduction in the amount of loss of ridge width and loss of ridge height in the test sites when compared to the control sites. The mean loss of ridge width was found to be 1.68 mm at the control sites and 1.07 mm at the test sites. The mean loss of ridge height was found to be 2.43 mm at the control sites and 1.45 mm at the test sites. All these differences were found to be statistically significant.

Interpretation and conclusion: The results of this study suggest that a ridge preservation procedure carried out at the time of extraction is a reliable and predictable method to minimize the resorption of the alveolar bone that takes place postextraction and offers the patients a relatively easy, cost effective method that spares them the discomfort of further ridge augmentation procedures that might be necessary for an esthetic rehabilitation or implant placement.

Zirconia Abutments: A Quintessence of Modern Day Implantology

[Year:2012] [Month:September-December] [Volumn:3 ] [Number:3] [Pages:48] [Pages No:133-137][No of Hits : 4178]


ABSTRACT

Dental implants are considered an essential treatment modality for replacement of both single and multiple teeth. Titanium abutments which have been used as gold standard exhibit a dull grayish hue and give an unnatural appearance. The mechanical advantage together with esthetic gain over the conventional abutments has made zirconia abutments the stateof- the-art option available for use in the present day. This article intends to review these zirconia abutments for its property and its clinical implication in the modern day practice.

Correlation between Gingival Phenotype, Residual Ridge Height and the Schneiderian Membrane

[Year:2012] [Month:September-December] [Volumn:3 ] [Number:3] [Pages:48] [Pages No:111-115][No of Hits : 4083]


ABSTRACT

Purpose: Sinus perforations are one of the most common complications during sinus augmentation procedures. Preoperative prediction of the antral membrane thickness would be of practical importance and serves as an additional information for surgical planning. The purpose of this study was to analyze a possible correlation and comparison between gingival phenotype and the residual ridge height on the dentulous and the edentulous side to the thickness of the healthy sinus mucosa.

Materials and methods:Twenty-five consecutive patients were included in the study; preoperative cone beam computed tomography (CBCT) scanning was performed to radiographically evaluate the gingival phenotype (GP), the height of the residual ridge (RRH) at the edentulous side and the dentulous side and thickness of the schneiderian membrane (SMT). The smallest RRH, highest SM and gingival thickness values were recorded. These values were classified as follows: RRH < or >3.5 mm; SM < or >1 mm; and GP < 1.5 or >2 mm.

Results: On the edentulous side, Strong correlations of GP with SM (r = 0.833, p < 0.001) and moderate between RRH with SM (r = 0.620, p = 0.001) and RRH with GP (r = 0.596, p = 0.001) were noted. On the dentulous side, strong correlations of GP with SM (r = 0.832, p < 0.001) and moderate between RRH with SM (r = 0.643, p = 0.001) and RRH with GP (r = 0.601, p = 0.001) were noted.

Conclusion: Within the limitations of the study, the gingival phenotype (GP) presents to be a reliable measure to predict the thickness of the SM and suggested that the GP, SM, RRH may be important factors for sinus perforation.

Implant-retained Mandibular Overdentures: A Comparative Study of Immediate Loading vs Delayed Loading after One Year

[Year:2012] [Month:September-December] [Volumn:3 ] [Number:3] [Pages:48] [Pages No:105-110][No of Hits : 3459]


ABSTRACT

Purpose: The aim of this study was to compare the clinical and radiographical outcomes of two loading protocols of mandibular overdentures supported by two unsplinted implants.

Materials and methods: Twenty completely edentulous patients were included in the study. Patients were categorized in two groups each containing 10 patients. In group A, patients received at least two implants in symphysis areas inserted after a minimal flap reflection, and 2 months after implant placement, a mandibular complete denture was connected to the implants using ball attachments. In second group, prosthesis was loaded immediately after placing the implants in symphysis areas without any flap reflection. Patients were examined at 1, 12, 24 and 48 weeks after loading. At postoperative visits, occlusion was checked and the need for any prosthesis maintenance was recorded. Mobility of the implants, radiolucency around the implant and amount of crestal bone loss was checked and measured for both groups during the checkup sessions. Also any prosthetic problems were recorded.

Results: After 12 months of loading, in both group no implant failure was reported and the survival rate was 100% in immediate and delay loading groups. Average of bone resorption in control group at the end of study was 0.84 ±0.05 mm and in the test group was 0.84 ±0.03 mm. In all patients after every 6 months the plastic O-rings were changed due to frictional wearing. In test group, in three patients the mandibular denture fractured, while, in control group it happened in two patients. In the test group, two patients experienced unbearable pain, while, in the control group seven patients experienced unbearable pain and they needed analgesics. None of the patients in test group experienced edema, swelling and discomfort after surgery due to flapless surgery, while in the control group four patients experienced edema and swelling after surgery.

Conclusion: The results of this study suggest that immediate loading of two implants supporting mandibular overdenture has outcomes comparable with conventional loading protocols. This clinical approach offers good stability and comfort while keeping high implant success rate.

Rehabilitation of a Patient using a Twin-Stage Technique to achieve Balanced Occlusion in Implant-Supported Overdenture: A Clinical Report

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:92-95][No of Hits : 3402]


ABSTRACT

Ideal occlusion on an osseointegrated implant has not been investigated with 6° of freedom biomechanically. The current accepted tenet is to avoid horizontal forces on fixtures and for edentulous cases, a balanced articulation must be created. Hobo and Takayama proposed a twin stage procedure to develop disocclusion and anterior guidance more precisely and scientifically. They concluded that effective cusp angle is the most reliable among all the factors effecting occlusion. They proposed a two stage procedure to develop effective cusp angle of 25º in order to achieve balanced occlusion in complete denture prosthesis. This clinical report describes a step-by-step procedure involved in developing balanced occlusion using twin stage technique in implant supported overdenture.

ABSTRACT

Root form dental implants have a high success rate and are commonly used for replacement of missing teeth, however failures occasionally occur, such implants must be removed. Like teeth, dental implants also establish microflora soon after placement and stable implants showed no significant shifts in the composition, whereas failing implants showed presence of Gram-negative anaerobic bacteria. This article reviews the microflora associated with dental implants.

[Year:2012] [Month:September-December] [Volumn:3 ] [Number:3] [Pages:48] [Pages No:150-153][No of Hits : 3031]


ABSTRACT

The posterior maxilla is a challenging site for dental implant rehabilitation. Anatomic limitations in this region provide challenges that may affect successful osseointegration and the fabrication of a functional and esthetic implant-supported prosthesis. The technique of sinus floor elevation has expanded prosthetic options by enabling the placement of additional implant support in maxillary segments with atrophic ridges and pneumatized sinuses.
