Abstract
The purpose of this study was to evaluate clinical and histological outcomes using a freeze-dried bone allograft (FDBA) combined with recombinant human bone morphogenetic protein-2 (rhBMP-2) in sinus floor augmentation. Sinus floor augmentation was performed in three patients using the FDBA and rhBMP-2. After a 5-month healing period, biopsies were performed simultaneously with implant surgery. It was possible to obtain enough bone to place implants quantitatively and to obtain excellent initial fixation of implants qualitatively. In this case series, the results showed that rhBMP-2 encourages bone formation and enough bone can be made to place implants when performing sinus floor augmentation with FDBA.
