Monday, May 1st, 2017

6. A Custom Made Implant Supported Auricular Prosthesis Designed by Rapid Prototyping for Compromised Bone Support: A Case Report

Implant supported auricular prosthesis requires a minimum of 6mm bone depth in the temporal bone area behind external auditory meatus. Extra oral implants are available from 4mm to 7mm length with 5 to 6mm diameter flange. When the bone height is compromised and when only few regions have favorable positions which are not part of the slot area all the existing extra oral systems cannot be used. In cases with compromised bone condition, a custom made implant is the best choice that can offer good prognosis.

12. Guided Bone Regeneration in Peri-Implantitis Bone Defect After Free Gingival Graft: A Case Report

Peri-implantitis is among the most common pathological conditions encountered in the field of implant dentistry, where regenerative therapy, when possible to perform, is needed. One of the reasons why bone regeneration in peri-implantitis defects is difficult: due to prosthetic reasons, submerged healing is often not possible to perform. Another difficulty arises particularly in cases of insufficient attached keratinized mucosa (KM), where the mobility of alveolar mucosa can increase leakage of grafting materials from the treated defect.  After a healing period of 5 months, an implant was placed in position #30 with further bone augmentation.

20. Computer Based Textural Evaluation of Concentrated Growth Factors (CGF) in Osseointegration of Oral Implants in Dental Panoramic Radiography

Concentrated growth factors (CGF) have positive impact in the field of regenerative medicine. The osseointegration properties of CGF around loaded oral implants were evaluated in this study by means of computerized textural analysis in Panoramic Radiographs.  All selected features achieved Area- Under-Curve (AUC) values within 0.77–0.81 range in the group with CGF employment and manage to capture the significant temporal textural differentiation that can be attributed to CGF properties.

Sticky Bone Use in Implant Dentistry

Monday, December 21st, 2015

“Sticky Bone” Use in Implant Dentistry

 

11. Utilization of Autologous Concentrated Growth Factors (CGF) Enriched Bone Graft Matrix (Sticky Bone) and CGF-Enriched Fibrin Membrane in Implant Dentistry

Platelets are known to release several growth factors which stimulate tissue regeneration. Several techniques for platelet concentrates have been introduced in surgical field for the prevention of hemorrhage and acceleration of tissue regeneration. Platelet rich plasma (PRP) and plasma rich in growth factors (PRGF) belong to the first generation of platelet concentrates. PRP and PRGF require chemical additives such as anticoagulants and thrombin or calcium chloride to induce fibrin polymerization before applying to the surgical site. Platelet rich fibrin (PRF) and concentrated growth factors (CGF), as second generation of platelet concentrate, utilizes patient’s venous blood alone to trigger platelet activation and fibrin polymerization.  PRF and CGF can be used as alternative to traditional barrier membrane over bone graft, therefore acceleration of tissue regeneration is acquired.

31. A New Paradigm for Fixed Complete Dentures

The ever expanding role of Zirconia is applied to one piece full arch implant supported restorations that mirror their metal counterpart in strength and versatility and exceeds them in complete passivity at the implant interface. Their overall natural appearance and refined esthetic is limited only by the mastery of the dentist / technician team that applies this new technology. The clinical and laboratory sequence of the prosthesis creation is presented from start to completion.

41. Gingival Grafting: A Novel Approach to Single Stage Augmentation for Root Coverage

The existence and preservation of attached keratinized gingiva around natural teeth and dental implants plays an important role in periodontal and peri-implant health. This paper describes a novel surgical technique that addresses multiple adjacent Miller class II and III recession defects in a predictable one staged surgical procedure. The goal of treatment is to improve esthetic outcomes, gain clinical attachment and keratinized tissue
levels in addition to possible root coverage. A combination of traditional periodontal plastic procedures is utilized with sound evidence based techniques.

55. Solving the Problem of Misangulated Implant Retained Overdenture with Bar Attachment: A Case Report

Mis-angulated implant is one of the main causes of frequent ball attachment maintenance, as a result of accelerated rate of plastic component wear. In this case report a treatment approach with bar retained implant mandibular overdenture were described to patient with history of frequent loss of retention of ball attachment retained mandibular implant overdenture the require new O-ring replacement of ball attachments every 6 weeks, the patient asked for solution for this problem as he cannot afford high coast of frequent maintenance.

Lateral Sliding Flap to Assist with Anterior Maxillary Dental Implant Esthetics

 

11. Laterally Sliding Flap Surgical Approach for Soft Tissue Closure in Post-Extraction Alveolar Ridges: Technique
and Clinical Results Presented in a Case Series

Since the decade of the 1970s different techniques have been developed to achieve primary closure. An alternate lingual/palatal sliding flap surgical technique to obtain primary soft tissue closure in post extraction socket sites was present with followed during six months.  The laterally sliding flap variant presented is a simple, versatile, and predictable, technique to obtain primary wound closure of maxillary and mandibular anterior teeth, while preserving the position of the mucogingival junction.

23. Multidisciplinary Approach for Treatment of Severly Resorbed Maxillary Anterior Ridge Complicated by Cysts in a
Single Surgical Session

Severe defects of the alveolar ridge can have many causes including the loss of teeth due to caries, periodontal problems, trauma and in some cases the presence of cystic lesions, which can cause severe bone resorption, which represent a challenge for the surgeons.  This article aims to present a case report in which through a multidisciplinary approach is achieved rehabilitate a returning patient function and aesthetics in a single surgical session.

31. Management of Complex Deeply Positioned, Severely Mal-Aligned Dental Implant: A Case Report

Misaligned implant presents a prosthetic challenge especially when accompanied with malposition. Sometimes such complex cases remain without restoration even if they are properly Osseo integrated. The fixed prosthesis which is the most acceptable option by the patient can be achieved by appropriate procedure as explained in this report to achieve a fixed prosthesis for such complex cases.

37. Management of the Wide Space in the Anterior Maxilla with a Dental Implant Restoration: A Case Report

Complications could occur subsequent to the implant restoration (for wide space management) of the anterior maxillary region. Therefore, to minimize these complications, meticulous examination, diagnosis, temporalization and the patient awareness of the final results should be taken into consideration. Also, in order to achieve the best results reshaping of associated teeth may become necessary through the course of treatment. Establishing soft tissue around implant restoration, appropriate emergence profile creation prior to implant restoration and space division between anterior incisors are critical factors behind harmonic appearance. The purpose of this paper is to describe a case report in which the wide edentulous space closure was accomplished using implant restorations.

21. Mandibular Reconstruction and Full Arch Rehabilitation with Dental Implants Following a Gunshot Injury: A Clinical Report

Management of gunshot injuries to the face led in many ways to the development of modern maxillofacial surgery, and it remains a cornerstone of the specialty of oral and maxillofacial surgery. Bone grafts are frequently required in the management of Gunshot wounds to the face, whether for replacement of true loss of bone or in cases in which comminuted and misplaced fragments need to be replaced or reinforced. Insertion of osseointegrated dental implants several months after mandibular reconstruction using bone grafts has proved to be a successful method to achieve mastication and complete oral rehabilitation. The successful restoration of patients with dental implants can result in a change in dental function and health.

Mandibular Reconstruction and Oral Rehabilitation with Dental Implants by Sequel of Ossifying Fibroma with 8 Years of Evolution: A Clinical Report

 

11. Mandibular Reconstruction and Oral Rehabilitation with Dental Implants by Sequel of Ossifying Fibroma with 8 Years of Evolution: A Clinical Report

Ossifying fibroma (osteogenic fibroma, Cemento-ossifying fibroma) is a true neoplasm with significant growth potential.  When the lesion obtains a relevant scale, results in a substantial osteolytic reaction, being essential surgical resection followed by bone grafting for functional reconstruction.  The mandibular reconstruction in the head and neck surgery has been a topic discussed throughout history, especially in the last 50 years. The use of iliac crest grafts followed by osseointegrated dental implants provides a valuable technique for the oral rehabilitation
in patients with this type of defects.

33. Dentin Autografts Maintain Alveolar Width Following Tooth Extraction

The aim of this study was to preserve alveolus by maintaining natural PDL with a buccal dentin autograft.   In the dog study, new cementum was found over both the cut and preexisting
dentin. No inflammation was noted. Half of the human’s models dentin autografts showed less resorption. One patient had equal resorption. Two slivers sloughed. In the second human study, all sites showed excellent healing. New periodontal ligament formed with new cementum over all autografts.

45. Complex Full arch Implant Impressions Simplified: A Clinical Tip for Accurate Predictable Impressions

Treating full arch multiple implant supported complex cases is clinically and technically challenging. To obtain precise and accurate impressions is critical to minimize the laboratory errors and prevent prosthesis misfit. Splinting of implant impression copings has been recommended when fabricating prostheses supported by multiple implants.

51. Regeneration of the Deficient Alveolar Ridge with Utilization of “Tunnel Approach” to Guided Bone Regeneration. A Retrospective Study of the Outcomes

Horizontal Ridge Augmentation & “Slam-Dunk” Implants

 

11. Horizontal Ridge Augmentation Using Titanium Tenting Screws Followed by Implant Placement

Many bone grafting methods have been proposed to reconstruct maxillary or mandibular edentulous ridges. The amount of resorption influences the outcome of any regeneration technique. Siebert classified ridge defects according to their morphology and severity.1 The “Siebert classification” has helped standardize communication among clinicians
in the selection and sequencing of reconstructive procedures designed to eliminate the classified defects. In addition to this classification, other factors (Table 1) should be included in considering the appropriate surgical technique.

19.The “Slam-Dunk” Implant – How Common Is It? A Report of 200 Consecutive Implants in a Military Treatment Population

Background: A “Slam-Dunk Implant” implies an easy case in which no initial site preparation is needed, no factors complicate placement, and a flapless approach may be used. But how common are such easy cases? How predictable is this assessment? Methods: A consecutive series of 200 implants in 161 patients (27 female, 134 male) was reviewed in a young and healthy military treatment population. Various complicating factors were examined, including those known beforehand, and those encountered during surgery.

31. Clinical Performance of Implant Supported All-Ceramic Restorations Using Ceramic Abutments: A 1-3 Year Follow Up Study

Titanium has been considered traditionally as the material of choice for implant abutments because of its well documented biocompatibility and mechanical properties. One of the challenges in implant dentistry is creating a gingival margin that resembles the appearance of its counterpart of a natural tooth. This can be difficult as titanium used in implants and abutments has color characteristics and light reflection properties that can compromise the appearance of the peri-implant gingival tissues.1 Moreover, titanium abutments and dental porcelains have different rates of thermal expansion and contraction, which makes fusing porcelain to titanium difficult.

41. Immunohistochemical Evaluation of the Effects of Propolis on Osseointegration of Dental Implants in Rabbit Tibia

Background: Dental implant is an artificial tooth root fixed into the jaws to hold a replacement tooth or bridge. Functional surface modifications by organic material such as propolis coating seem to enhance early peri-implant bone formation, enhancing the initial cell attachment. The aim of the study was to study the expression of osteocalcin and collagen I as bone formation markers in propolis coated and uncoated implant in interval periods( 1, 2, 4 and 6 weeks). Materials and Methods: Commercially pure Titanium (cpTi) implants, coated with propolis
protein, were placed in the tibias of 40 New Zealand white rabbits, histological and immunohistochemical tests for detection of expression of osteocalcin and collagen I were performed on all the implants of both control and experimental groups for (1,2,4 and 6 weeks) healing intervals.

11. Immediate Placement of Mandibular Molar Dental Implants: Case Report By Dr. Mohit Zamad, Dr. Aakanksha Zamad, Dr. Akshay Daga, Dr. Pankaj Akhare

The Esthetics and functional integrity of the periodontal tissues may be compromised by dental loss. Implant has become a wide option to maintain periodontal architecture. Diagnosis and treatment planning is the key factors in achieving the successful outcomes after placing and restoring implants placed immediately after tooth extraction. This case report describes the procedure of placement of implant in the anterior teeth region after immediate extraction.

19. Treatment Planning Considerations for Cemented Versus Screw-Retained Single Tooth Dental Implant Restorations in the Aesthetic Zone – Advantages, Disadvantages and Maintenance Issues: A Literature Review By Kenneth K.H. Cheung

The use of a single implant retained crown to replace a missing tooth has gained popularity since 1990. There are two design options for the implant supported crown: the crown can be cemented onto an implant supported abutment (be it pre-fabricated or custom designed, as would be done if the crown were tooth supported) or the crown can be a screw-retained, direct-to-fixture crown (provided that the implant has been placed at the correct axial inclination). Different philosophies exist regarding the best type of implant restorations in the aesthetic zone. The literature details the advantages and disadvantages for both screw- and cement- retained implant prosthesis.

31. Ultraviolet Photofunctionalization of Dental Implant Surfaces: A Review By Dr. Suraj Khalap, Dr. Ajay Mootha, Dr. Ramandeep Dugal

Ultraviolet photofunctionalization of titanium implants has shown promising results for treatment outcomes. Photofunctionalized dental implants have shown promising findings in regards to bone implant contact, osteoblast response, and dental implant stability, hence opening up the avenue to be incorporated in daily implant practice. This article summarizes the findings of all the recent in vivo & in vitro research conducted regarding UV photofunctionalization of titanium implants.

41. A Report of Three Dental Implant Fractures with Literature Review By Dr. Ahmad Rohania, Dr. Abbas Taher, Dr. Ammar Albujeer Shawki, Dr. Salma Pirmoazzen

Dental implant fracture is one of the rare complications in implant dentistry. Such fractures pose important problems for both the patient and the dental surgeon. According to most literature sources, the prevalence of dental implant fractures is very low with approximately 2 fractures per 1000 implants placed. Considering that implant placement is becoming increasingly popular, an increase in the number of failures due to late fractures is to be expected. Clearly, careful treatment can contribute to reduce the incidence of fracture. An early diagnosis of the signs alerting to implant fatigue, such as loosening, torsion or fracture of the post screws and prosthetic ceramic fracture, can help prevent an undesirable outcome. Also it is important to know and apply the measures required to prevent implant fracture. This article presents three cases with fractured dental implants and discusses management options and possible causal mechanisms underlying such failures, as well as the factors believed to contribute to implant fracture with literature review.

Ameloblastoma Treatment and Reconstruction

11. Odontogenic Tumor: A Case Report of a multicystic ameloblastoma in mandible treated with intraoral bone graft surgery and osseointegrated implants By Luis Eduardo Benevides de Moraes, Eduardo Jose de Moraes, Nathalia Benevides de Moraes

The ameloblastoma is an invasive odontogenic tumor with benign character and might promote bony destruction. A large number of approaches are preconized such as aggressive resections with safety margin which lead to functional and esthetical sequelae. The present article consists in a case report of a 24 years old female patient presenting a multicystic ameloblastoma in the anterior region of the mandible. The patient was submitted to a conservative resection followed by bony reconstruction with autogenous bone graft taken from the retromolar region associated to PRP ( platelet-rich plasma). After satisfactory remodeling of the graft, osseointegrated implants were installed and the patient was rehabilitated with a fixed prosthesis. Patient was followed for a period of 5 years showing no signs of recurrence. It is possible to conclude that the treatment performed in this case provided lower morbidity and was able to satisfy patient’s expectations.

21. Improving Peri-implant Soft Tissue Profiles Using a Novel Immediate Provisionalization and Flapless Implant Placement Technique: Case Presentation By Mohamad Koutrach, Bassam M. Kinaia, Harold E. Goodis

Achieving predictable esthetic results in the anterior maxilla are a challenge for clinicians mainly due to lack of adequate soft and hard tissues volume. To predictably obtain pleasing results, early soft tissue management is necessary especially during implant temporization period.

41. Substance Abuse & Misuse of Prescription Drugs for Temporomandibular Disorders By Paul J. Flaer, Jai Parkash, Saif Algarugly, Seng Kyu Choi

Prescription drugs in the United States are often subject to abuse or misuse. Opioids are the most abused and misused analgesics of the narcotic drugs. The article deals with abuse and misuse problems associated with other groups of prescription drugs that are used in temporomandibular joint (TMJ) therapy, i.e., tranquilizers, muscle relaxants, and antidepressants. Therapy for Temporomandibular Disorder (TMD) often employs these drugs on an acute or chronic basis.
