Abstract
Sinus augmentation with various bone graft materials may be required in the posterior maxilla. This study compared bone formation in a lateral window sinus augmentation with recombinant human bone morphogenetic protein 2/acellular collagen sponge (rhBMP-2/ACS) combined with Bio-Oss or Bio-Oss graft alone. Patients were assigned to treatment with either rhBMP-2/ACS + Bio-Oss or Bio-Oss alone. After a healing period, bone cores were harvested. Histologic specimens demonstrated that new bone formation was less in those who received rhBMP-2/ACS + Bio-Oss than those with Bio-Oss alone. This study indicated that the addition of rhBMP-2/ACS to Bio-Oss has a negative effect on bone formation.Entities:
