摘要

本篇報告在探討於台北長庚醫院口腔外科從2000至2004年內進行上顎齒槽骨牽引術，其中使用骨內或骨膜外牽引來完成牙骨嵴增高手術共七例，並探討其治療效果與治療過程中所引發的併發症及處理方式。齒槽骨牽引術，在人工植牙的領域確實有其效用，尤其是應用於齒槽骨高度不足的情形，比傳統誘導骨生長術在更短時間就可達到效果。在完成牽引的病例中，增高幅度由6 mm到12 mm，平均達9.6mm，這七病例中也發現了一些缺失，所有的移動骨塊(Transport segment)都向腭側傾斜，因此在人工植體準備區都必須予以進行第II階段的頰側面缺損補骨手術。在牽引過程中皆無骨塊斷裂的現象。

Alveolar distraction osteogenesis is a relatively novel procedure by which alveolar bone and underlying mucosa are regenerated. It is now being widely used for treating severe alveolar ridge atrophy, especially before the placement of dental implants. The purpose of this retrospective study was to evaluate the clinical outcomes and complications of alveolar distraction osteogenesis in anterior maxilla. From 2000 to 2004, 7 patients with alveolar ridge deficiency of anterior maxilla were treated with distraction devices, including intraosseous or subperiosteal type, at the department of oral surgery, Chang-Gung memorial hospital, Taipei. After distraction, the distracted height was increased from 6 to 12 mm, the average was 9.6 mm. However, a minor complication was found in all cases that the segment moved toward to palatal, which resulted in the necessity of secondary bone grafting procedure before dental implant placement. No complication of transport segment fracture was observed in any case.
