The use of cancellous block allograft for sinus floor augmentation with simultaneous implant placement in the posterior atrophic maxilla.
BACKGROUND The simultaneous placement of dental implants during sinus augmentation is advocated in cases in which >or=4 to 5 mm of alveolar bone exists coronally to the sinus floor. The aim of the present study was to assess the survival rate of dental implants placed during sinus augmentation and stabilized by the use of cancellous freeze-dried block allograft. Residual alveolar ridge height <...
متن کاملSinus augmentation using rhBMP-2-loaded synthetic bone substitute with simultaneous implant placement in rabbits
PURPOSE The aim of this study was to determine the effect of recombinant human bone morphogenetic protein-2 (rhBMP-2)-loaded synthetic bone substitute on implants that were simultaneously placed with sinus augmentation in rabbits. METHODS In this study, a circular access window was prepared in the maxillary sinus of rabbits (n=5) for a bone graft around an implant (Ø 3×6 mm) that was simultan...
متن کاملEfficacy of cancellous block allograft augmentation prior to implant placement in the posterior atrophic mandible.
BACKGROUND The present study evaluated the outcome of ridge augmentation with cancellous freeze-dried block bone allografts in the posterior atrophic mandible followed by placement of dental implants. MATERIALS AND METHODS A bony deficiency of at least 3 mm, horizontally, vertically, or both, according to computerized tomography (CT) para-axial reconstruction served as inclusion criteria. Imp...
متن کاملLocalized maxillary ridge augmentation with a block allograft for dental implant placement: case reports.
Autogenous block bone grafts have been highly successful in treating human periodontal defects, restoring esthetics, and developing adequate bone volume for dental implant placement. Limitations in available donor bone, the need for an added surgical procedure, and other potential complications have made the use of allogenic bone graft materials an important alternative. One patient described i...
متن کاملRabbit maxillary sinus augmentation model with simultaneous implant placement: differential responses to the graft materials
PURPOSE This study was performed to establish an experimental rabbit model for single-stage maxillary sinus augmentation with simultaneous implant placement. METHODS Twelve mature New Zealand white rabbits were used for the experiments. The rabbit maxillary sinuses were divided into 3 groups according to sinus augmentation materials: blood clot (BC), autogenous bone (AB), and bovine-derived h...
