Alveolar distraction osteogenesis versus autogenous onlay bone grafting for alveolar ridge augmentation: Technique, complications, and implant survival rates

The aim of this study was to define the techniques and compare the complications and implant survival rates in localized alveolar deficiencies reconstructed by alveolar distraction osteogenesis (ADO) or autogenous onlay bone grafting (ABG).

Description
Summary:The aim of this study was to define the techniques and compare the complications and implant survival rates in localized alveolar deficiencies reconstructed by alveolar distraction osteogenesis (ADO) or autogenous onlay bone grafting (ABG). Thirty-six patients were treated with ADO or ABG harvested from the mandibular ramus. Twenty-four distractions in 22 patients (ADO group) and 18 ramus grafts in 14 patients (ABG group) were performed. Complications and implant survival rates were evaluated. The overall complication rates were 66.8% and 38.8% in the ADO and the ABG groups, respectively. Implant survival rates were 91.4% and 93.7% in the ADO and the ABG groups, respectively. The complication rate was higher in the ADO group, but the complications were mainly minor, and management was easier in this group than in the ABG group. Although follow-up was shorter, the implant survival rate was slightly higher in the ABG group compared with ADO group.
