OBJECTIVE
The aim of this study was to evaluate alveolar distraction osteogenesis (ADO) and autogenous onlay bone graft (AOBG) procedures by comparing their long-term results and their ability to correct severe vertical alveolar defects for further rehabilitation.
STUDY DESIGN
Fourteen patients treated with ADO and 28 patients treated with AOBG were included in this study. Radiographic measurements of alveolar bone heights over time and the implant survival and success were compared for the 2 groups.
RESULTS
The vertical bone gain was 8.4 ± 2.6 mm for ADO and 6.5 ± 2.3 mm for AOBG. After a mean follow-up period of 7.1 years, there was no significant difference between the 2 groups regarding alveolar bone heights over time and implant survival and success (P > .05). The cumulative survival and success rates were 97.3%, 92.7% in the ADO group and 94.1%, 90.2% in the AOBG group, respectively.
CONCLUSION
Both ADO and AOBG may be reliable and effective for ridge augmentation procedures of severe vertical alveolar bone defects and subsequent dental rehabilitation using implants.
目的
本研究旨在通过比较肺泡牵张成骨术（ADO）和自体骨移植（AOBG）的长期效果及其纠正严重垂直牙槽骨缺损以进行进一步修复的能力，来评估这两种方法。
研究设计
本研究纳入了 14 例接受 ADO 治疗的患者和 28 例接受 AOBG 治疗的患者。比较了两组患者的牙槽骨高度随时间的放射学测量值以及种植体的存活率和成功率。
结果
ADO 的垂直骨增量为 8.4 ± 2.6mm，AOBG 的垂直骨增量为 6.5 ± 2.3mm。在平均 7.1 年的随访期后，两组患者的牙槽骨高度随时间的变化、种植体的存活率和成功率均无显著差异（P＞.05）。ADO 组的累积存活率和成功率分别为 97.3%和 92.7%，AOBG 组分别为 94.1%和 90.2%。
结论
ADO 和 AOBG 均可用于严重垂直牙槽骨缺损的牙槽嵴增量术以及随后使用种植体进行的牙齿修复，是可靠且有效的方法。
