[Single-stage implants in areas of maxillary sinuses that were augmented with allograft. Case reports]

Demineralized freezed dried bone allograft (DFDBA) is known as a bone inductive material, and used widely in periodontal and bone regeneration procedures. DFDBA can also be used for sinus floor augmentation prior or with implant placement. The present manuscript described cases of single-stage implants that were used successfully in areas where the maxillary sinus was augmented with DFDBA simultaneously with implant placement (Case 1) or in a second procedure, 18 months following grafting of the sinus (Case 2). These cases demonstrated the ability to use single-stage implants in the augmented maxillary sinus, in a separated or simultaneous procedure.
