ORTEGA-LOPES, Rafael et al. Retrospective four year analysis in 199 bone grafts of the alveolar ridge. RGO, Rev. gaúch. odontol. (Online) [online]. 2012, vol.60, n.1, pp. 79-83. ISSN 1981-8637.

Objective To evaluate the factors that lead to complications in autogenous bone grafting. Methods Review of clinical records of the patients that were candidates for rehabilitation, between May 2004 and December 2008. With regard to the donor area, of the 199 reconstructions, 175 were autogenous bone graft procedures and 210 donor areas were acted upon. Results A total of 48 procedures (24.12%) were grafts using particulate bone while sinus lift grafts were performed on 28 patients (14.07%). Osteogenesis distraction and inferior alveolar nerve lateralization were performed in five (2.51%) and three (1.51%) procedures respectively. Eleven autogenous bone grafts were lost, of which 90.9% were onlay block. Conclusion The use of autogenous bone grafting in atrophic alveolar ridge reconstruction is a highly successful treatment, and the sinus lift procedure is the most predictable form of treatment.
