Aim and Objective : The aim of this study was to describe clinically the prevalence of postsurgical complications in a group of patients treated with autologous bone grafts obtained from the mandibular ramus. Materials and Methods: Data were obtained from a sample of 76 adults, who were subjected to a surgical procedure of horizontal bone augmentation through autologous onlay bone grafts obtained from the oblique line of mandible. A total of 113 onlay grafts were removed and placed in 152 recipients' area, previously fitted to the receptor site and stabilized through two fixation screws. All complications were recorded in relation to the recipient and donor sites, and the follow-up time of the sample was of 2 years. Results: Of the entire sample studied, 69.7% did not show any type of postsurgical complication; however, 30.3% of them exhibited a type of complication, with temporary paresthesia being the most prevalent (7.9%). Conclusion: More than 30% of the patients that received horizontal bone augmentation through autologous onlay bone grafts obtained from the oblique line according to the conventional technique showed some type of postsurgical complication.
