LOPEZ LOPEZ, Ana María et al. Maxillary sinus augmentation with bovine hydroxyapatite alone: a safe technique with predictable outcomes in patients with severe maxillary atrophy. Rev Esp Cirug Oral y Maxilofac [online]. 2015, vol.37, n.2, pp.87-92. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2014.07.010.

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.
