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 < 0.001), and the RB group demonstrated significantly lower resorption than the CB and IB groups (p = 0.011 and p < 0.001, respectively). The most common postoperative complications included neurosensory disturbance in the CB graft and gait disturbance in the IB graft. Out of the 92 implants inserted after augmentation, four implants were lost during the study period, resulting in an implant success rate of 95.65%.

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.

不同类型自体块骨移植后垂直骨吸收的比较。
背景:本研究旨在测量和比较使用不同类型的自体块骨垂直增强后垂直骨吸收的差异。方法:收集38例患者的数据,这些患者在植入前使用自体块骨进行了垂直嵴隆凸。根据供体部位将患者分为三组:支骨(RB)、下巴骨(CB)和髂嵴骨(IB)。结果:在长达60个月的随访期内评估了隆胸的手术结果。在38名患者中,垂直骨增加的平均量为8.36 ± IB组为1.51 mm,其次为RB组(4.17 ± 1.31mm)和CB组(3.44 ± 1.08mm)。两组之间的垂直骨吸收有显著差异(p 结论:RB移植物可能是保持术后垂直高度和降低发病率的最合适的垂直增强选择,尽管与其他块骨相比,IB移植物的初始增益更大。
