A clinical study of iliac bone graft using subperiosteal tunneling method for alveolar ridge augmentation

Purpose: The objective of this study was to evaluate the efficacy of the subperiosteal tunneling technique with iliac block bone graft for bone augmentation in an edentulous alveolar ridge. Patients and Methods: Total of 8 sites in 7 patients were included in this study. The bone height was evaluated by CBCT preoperatively and 4 months after operation. Total of 11 implants were inserted and evaluated clinically and radiographically. Results: Mean value of the increased bone height was 6.29 mm and no implant failure was observed. There were no complications such as soft tissue dehiscence, exposure of the grafted bone and infection. Conclusion: We have achieved excellent clinical outcomes by this technique, so we concluded that it is useful for augmentation of severely deficient alveolar ridge.
