Abstract
Background : This study aims to measure and compare the differences in vertical bone resorption after vertical augmentation using different types of autologous block bone.
Methods : Data were collected from 38 patients who had undergone vertical ridge augmentation using an autologous block bone before implant insertion. The patients were divided into three groups based on the donor sites: ramus bone (RB), chin bone (CB), and iliac crestal bone (IB).
Results : The surgical outcome of the augmentation was evaluated at the follow-up periods up to 60 months. In 38 patients, the mean amount of vertical bone gain was 8.36?±?1.51 mm in the IB group, followed by the RB group (4.17?±?1.31 mm) and the CB group (3.44?±?1.08 mm). There is a significant difference in vertical bone resorption between the groups (p?
Conclusions : The RB graft might be the most suitable option for vertical augmentation in terms of maintaining postoperative vertical height and reducing morbidity, although the initial gain was greater with the IB graft compared to other block bones.
