Abstract
Sinus augmentation is a preprosthetic technique for rehabilitating posterior sector of the atrophied maxilla with implant-supported prosthesis. We retrospectively analyzed 34 consecutive sinus augmentations performed using only bovine hydroxyapatite. The presurgical height in 92% of the cases was 4 mm or less. The success rate of the maxillary sinus augmentation was 100% for this technique. 13.4% of the implants were placed immediately with a success rate of implants placement of 93.9%. The non-osseointegrated implants were all successfully replaced. Follow-up period was 1268 days. The success rate obtained using bovine hydroxyapatite alone is similar to that using other types of materials, while avoids morbidity of the autologous bone donor area.
