INFANTE-COSSIO, P. et al. Bone cavity augmentation in maxillofacial surgery using autologous material. Rev Esp Cirug Oral y Maxilofac [online]. 2007, vol.29, n.1, pp.7-19. ISSN 2173-9161.

Although a large number of materials have been described for augmenting bone cavities, the best material is still autologous cortical-cancellous bone or bone chip, which can form new bone through osteogenesis, osteoinduction and osteoconduct ion mechanisms. The oral and maxillofacial surgeon needs to be familiar with the biological properties and the fundamental characteristics of autologous material, the different techniques for obtaining it and its clinical application. Donor sites should preferably be intraoral. Bone filters and scrapers should be used for small defects, and the iliac, tibial or calvaria bones [should be used] when more quantity is required. There are no conclusive studies with regard to combining bone grafts with membranes. The combination of autologous grafts with other augmentation material has led to multiple studies, although definitive conclusions cannot yet be established. Autologous bone should be chosen for augmenting bone cavities, as it is useful for solving a variety of clinical situations in a simple, fast and safe manner.
