MIGUEL JUNIOR, Hid et al. Autogenous block bone graft in the upper jaw: report of case. Rev. Assoc. Paul. Cir. Dent. [online]. 2016, vol.70, n.2, pp. 198-203. ISSN 0004-5276.

The installation of implants in areas of bone loss may be associated with an unfavorable ratio crown-implant, unsatisfactory aesthetic result and cleaning difficulties, impairing treatment prognosis. The bone graft allows the installation of implants in a favorable three-dimensional position. Some methods have been studied and proposed for the reconstruction of lost alveolar bone: autogenous bone grafts, homogeneous bone, allogenic, xenogenous and alloplastic bone substitutes. There is still the guided bone regeneration, distraction osteogenesis, growth factors and combinations of these referred methodologies. Among the materials available, the autogenous bone is considered as the first option for bone reconstruction, considered the gold standard in bone grafting because it provides the most favorable conditions for post-surgical repair, presenting the properties of osteoconductive, osteoinductive and osteogenesis, helping the correction of the defects of thickness, since there is a good blood supply in the area. This work shows a bone grafting technique in autogenous block by performing a case for the reconstruction of atrophic maxilla, in order to increase bone volume available for the installation of dental implants.
