摘要

本篇研究探討下顎骨重建以單層腓骨游離皮瓣進行垂直牽引術配合人工植牙治療的臨床結果。於2003至2009年間，共10位患者，6位男性，4位女性，平均年齡為28歲，因不同原因造成下顎骨缺損而接受重建，經垂直骨牽引術後腓骨高度為22.9±4.56mm，平均增加10.7±3.19mm，所增加的骨高度比例為1.88。研究中使用植體數量為35支，平均牙冠與植體長度比為1.26，經過平均68.4個月追蹤評估植體周圍骨喪失的量，近心側平均喪失0.44±0.42mm，遠心側平均喪失0.48±0.52mm，兩者之間未達到統計學上差異（p=0.725）。所有患者最終都完成全口重建並達到良好的咬合功能，但過程中有80%病患發生程度不等的併發症仍是此方法有待克服之處。

The purpose of this study was to evaluate the outcome of dental implants placed on vertically distracted fibula osteoceptocutaneous free flaps for segmental mandibular defect reconstruction. Between 2003 and 2009, 10 patients (6 males, 4 females), aged from 20 years to 46 years (mean age 28 years) underwent segmental mandibular defect reconstruction using vertical distraction osteogenesis of single-barreled fibular with secondary dental implants. The mean post vertical distraction bone height was 22.9 ± 4.56 mm, representing a mean increase of 10.7 ± 3.19 mm and an increased bone height ratio of 1.88. Total 35 dental implants were used and the mean crown-implant fixture ratio was 1.26. After mean follow up 68.4 months, the mean marginal bone loss was 0.44 ± 0.42 mm at mesial side and 0.48 ± 0.52 mm at distal side, no significant difference noted between mesial and distal bone loss. All mandibular reconstructions in our patients were completed with successful occlusal function eventually, but a remarkable number of complication was encountered during the treatment course.
