Sinus floor augmentation using a composite graft of bone morphogenic protein-2 and allogenic cancellous bone (Puros):...

Reconstruction of the atrophic maxilla is a difficult task. The gold standard for such reconstruction is autogenous bone. Presently, many excellent products are available to the dental surgeon to facilitate alveolar reconstruction in the absence of autogenous bone. This study describes the use of bone morphogenic protein in combination with allogenic bone substitute (Puros) to reconstruct the maxilla in preparation for dental implant placement.
