BACKGROUND
Severely resorbed ridges present a great challenge to prosthodontic rehabilitation. Available reconstructive options include autologous/alloplastic augmentation with questionable results, or regeneration of new bone under gradual and controlled tension using distraction osteogenesis. This study focused on use of distraction osteogenesis for the treatment of vertically deficient alveolar ridges to assess its feasibility and outcome.
MATERIALS AND METHODS
Alveolar distraction osteogenesis (ADO) was studied at 10 different intra-oral, partial or complete edentulous sites. After a latency period of 5 days, distraction was carried out for 6-7 days at the rate of 0.5 mm every 12 hours (1 mm/day). Distractor was removed after a consolidation period of 12 weeks.
RESULTS
The mean height gained at the 10 intra-oral sites was 4.8 mm with standard deviation of ± 0.056. The mean follow-up period was 2 years. Complications of therapy included hardware failure, wound gape and extra-oral scar. The overall complication rate was 10%.
CONCLUSION
Distraction osteogenesis is a promising option to aid uneventful prosthodontic rehabilitation of severe vertically resorbed alveolar ridges.
背景
严重吸收的牙槽嵴给口腔修复带来了巨大挑战。现有的重建方法包括自体/异体植入，但效果存疑，或者采用牵张成骨技术在逐渐控制的张力下再生新骨。本研究聚焦于使用牵张成骨技术治疗垂直高度不足的牙槽嵴，以评估其可行性和治疗效果。
材料与方法
在10个不同的口腔内部分或全口无牙颌部位进行牙槽嵴牵张成骨（ADO）研究。经过5天的延迟期后，以每12小时0.5毫米（1毫米/天）的速度进行6 - 7天的牵张。在12周的愈合期后取出牵张器。
结果
10个口腔内部位获得的平均高度为4.8毫米，标准差为±0.056。平均随访期为2年。治疗并发症包括器械故障、创口裂开和口外瘢痕。总体并发症发生率为10%。
结论
牵张成骨是一种有前景的方法，有助于严重垂直吸收的牙槽嵴顺利进行口腔修复。
