A variety of biomaterials are used when performing sinus augmentation techniques. Bovine hydroxyapatite (BH) has already been demonstrated to present osteoconductive properties. The aim of this article is to provide a histologic and histomorphometric analysis, at 26 months, of a bone specimen extracted from a BH maxillary sinus graft. Histomorphometric results showed 64.4% bone density and 24.4% biomaterial density. Histologic analysis revealed marked bone formation and high osteoconductive properties in the BH particles, with no associated signs of inflammation. Resorption appeared minimal. BH seems to present high biocompatibility and osteoconductive properties.
