Mandibular Block Autografts for Alveolar Ridge Augmentation Mandibular Block Autografts for Alveolar Ridge Augmentation

Summary:

Reconstruction of alveolar ridge deficiencies requires bone augmentation before implant placement. Osseous defects occur as a result of trauma, prolonged edentulism, congenital anomalies, periodontal disease, and infection, and they often require hard and soft tissue reconstruction. Autogenous bone grafts have been used for many years for ridge augmentation and are still considered the gold standard for jaw reconstruction. The use of autogenous bone grafts with osseointegrated implants originally was discussed by Bra°nemark and colleagues, who often used the iliac crest as the donor site. Other external donor sites include calvarium, rib, and tibia. For repair of most localized alveolar defects, however, block bone grafts from the symphysis and ramus buccal shelf offer advantages over iliac crest grafts, including close proximity of donor and recipient sites, convenient surgical access, decreased donor site morbidity, and decreased cost.

This article reviews indications, limitations, presurgical evaluation, surgical protocol, and complications associated with mandibular block autografts harvested from the symphysis and ramus buccal shelf for alveolar ridge augmentation. The author draws from 14 years of experience with more than 500 mandibular block autografts.

Brånemarket al1 originally described autologous bone grafts used with dental implants,and they are now a well-accepted procedure in oral and maxillofacial rehabilitation. Placement of an end osseous implant requires sufficient bone volume for complete bone coverage.Further-more,the patter no fridge resorption ,which contributes to a nun favorable maxillo mandibular relationship,requires angulation of the implant and/or angled abutment,and affects the proximity of adjacent facial concavities (maxillary sinus,nasal cavity)and vital structures(mandibular nerve).

Use of Bone Grafts for the Enhancement of a GTR-Based Root Coverage Procedure: A Pilot Case Study
The use of guided tissue regeneration (GTR) procedures for the treatment of gingival recession has shown encouraging results and is gaining clinical acceptance. However, attaining space maintenance beneath the membrane remains a problem for clinicians. Hence, the purpose of this pilot case study was to evaluate the effect of adjunctive demineralized freeze-dried bone allograft (DFDBA) placement during collagen membrane GTR-based root coverage procedures. Five patients with Miller Class I or II defects…

BMP, PRP, PRGF and PRF; At the Edge of Regenerative Surgery
Biological modifiers and growth factors are substances that the body produces naturally in response to injury or disease. The use of these substances in regenerative procedures has made hard and soft tissue regeneration more predictable while accelerating healing and decreasing patient morbidity. This webinar will review the wound healing process and the role that growth factors play in regeneration. BMP, PRP, PRF and PRGF will be reviewed and their clinical applications will be demonstrated. At the end of this webinar the participant will have a good understanding of the differences between these biological modifiers and their benefits.

Managing Esthetic Implant Complications Premium Member Content

Managing Esthetic Implant Complications
Dental implant success today is judged not only by osseointegration but also by bone, tissue stability and of course long term esthetic results. Cosmetic predictability can often be difficult to attain, and esthetic implant failures can be multifactorial and patient management issues. Once esthetic implant failures occur, many cannot be fully corrected. Some complications must be addressed by an interdisciplinary dental team. In this summary of case reports, surgical considerations are provided, including cases of facial asymmetry/recession due to facial implant placement or bone loss resulting from technique/treatment failures, as well as papillary deficiencies. Restorative considerations for correcting failures are also discussed.
