The specific aim of this study was to determine the response of alveolar bone after it was augmented vertically using distraction osteogenesis and subsequently loaded with implant restorations. Four dogs each had four implants placed horizontally into an edentulous mandibular quadrant and, after integration, a distraction osteogenesis device was fabricated in the laboratory. An osteotomy was ma...

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 betw...

discussion this segmental ridge-split procedure with gradual bone expansion provides a quicker method wherein an atrophic ridge can be predictably expanded and eliminating the need for a second surgical site. this technique also shows that immediate implantation in split ridge of mandible can be performed. introduction narrow alveolar ridges especially in posterior mandibular remains a serious ...

Background: Reconstruction of severely resorbed jaws requires different surgical procedures to restore the correct bone morphology. These procedures often involve the use of bone substitutes or the harvesting of autologous bone from a donor site. Autologous bone is still regarded as the “gold standard” for augmentation procedures because of its osteogenic potential, but this graft has limited a...

BACKGROUND Conventional dentoalveolar osseous reconstruction often involves the use of grafting materials with or without barrier membranes. The purpose of this study was to evaluate the efficacy of bone induction for the placement of dental implants by two concentrations of recombinant human bone morphogenetic protein-2 (rhBMP-2) delivered on a bioabsorbable collagen sponge (ACS) compared to p...

BACKGROUND The aim of the present study was to evaluate clinically and radiographically, the efficacy of immediate ridge augmentation to reconstruct the vertical and horizontal dimensions at extraction sites of periodontally hopeless tooth using an autogenous chin block graft. MATERIAL AND METHODS A total of 11 patients (7 male & 4 female) with localized advanced bone loss around single roote...

The aim was to present the successful esthetical and functional rehabilitation of partial anodontia in a case of severe ectodermal dysplasia with complete atrophy of the jaws. A 17-year-old male with Class III malocclusion with partial anodontia sought dental implant treatment. His expectation was that of Class I occlusion. The challenge in the case was to match the expectation, reality, and th...

In recent years, the delivery of osteoinductive factors such as bone morphogenic proteins (BMPs) has become an alternative approach to traditional bone grafting due to their capacity to produce bone healing and new bone formation. BMP-2 has proved to possess the highest osteoinductive potential among BMPs. The case reported the clinical use of recombinant human BMP-2 for bilateral vertical alve...

background: alveolar ridge preservation could be performed immediately following tooth extraction to limit dimensional changes of alveolar process due to bone resorption. the aim of this study was to compare the clinical and histologic outcomes of socket preservation using two different graft materials; deproteinized bovine bone mineral (dbbm) and demineralized freeze‑dried bone allograft (dfdb...
