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.

Guided Bone Regeneration Using a Titanium Membrane at Implant Placement: A Case Report and Literature Discussion
Reconstruction of the oral supporting tissues lost by disease or trauma is essential to tooth replacement with dental implant therapy. This treatment requires evidence based augmentative procedures combined with up-to-date and current techniques. Guided bone regeneration (GBR) aims to initialize this process of alveolar ridge reconstruction by utilizing biologically active and supportive materials best coupled to the body’s healing processes. The use of nonresorbable, titanium membranes can achieve GBR by ensuring graft stability and space maintenance so as to ensure optimal neovascularization. Hereafter is a case report of a ridge defect reconstructed at implant placement, with the rationale and current, evidence-based literature discussed.

A Clinical Update in Bone Regeneration: Autogenous Bone vs. BMP-2
For historical and biological reasons autogenous bone has long been considered the gold standard of bone graft materials. For bone augmentation procedures autogenous grafts provided predictable volume gains, favorable bone quality with short healing periods. However, the need to harvest the graft and associated morbidity are inherent disadvantages. The choice of a technique for bone augmentation is dependent on a number of factors including the use of bone substitutes. More recently recombinant human bone morphogenetic protein (rhBMP-2) has been shown to be effective in repairing buccal wall defects from extractions and in sinus bone grafting. The use of rhBMP-2 is currently under clinical investigation as a replacement for autograft in ridge augmentation process.

Fibrin-Guided Bone Regeneration: Guidelines of a Simple, Predictable, & Low Risk Technique
This lecture is focused on an effective regenerative approach, but at low knowledge. The goal is to provide a new skill in favor of well-established techniques. The Fibrin Sealant (FS) is an additional clot of human origin. It has adhesive, sealant and inductive action stimulating hard and soft-tissue regeneration. The FS, mixed with bone chips and biomaterials, allows a better handling of the graft that, becoming plastic and moldable, adapts perfectly to bony defects without dispersion of granules. It’s effective also on wound protection achieving a faster healing of soft-tissue. This approach is excellent in the socket preservation and in the peri-implant regeneration on "closed" sites where the implants are inside the defects.

Complete Management of the Implant Site: From Simple Cases to Complex Situations Premium Member Content

Complete Management of the Implant Site: From Simple Cases to Complex Situations
The health and the structure of the peri-implant tissue is vital for a long term prognosis of aesthetic and functional dental treatments. The prevalence of peri-implant diseases and recessions is a problem that must be overcome by a perfect treatment planning, along with a step-by-step design of the future restorations. When the clinician places an implant, he must consider the 3D positioning regarding the hard and soft tissue. When one decide to restore an implant, he must be aware of the gingival volume and it’s position. In this presentation, we want to show fully documented cases, from bone grafting, soft tissue enhancement, to final restorations.
