摘要

目的：以三維模擬分析研究正顎手術之術前與術後，骨塊間的相關解剖位置的變化。方法：本研究使用電腦輔助設計／電腦輔助，以分析15位接受正顎手術病患手術前與手術後骨塊間的關係。結果：本研究使用電腦輔助設計／電腦輔助製造手術導板規劃切線及切割完成勒佛氏I型截骨術所花費的平均時間為48分鐘；右上門齒切緣之中點偏移量平均為1.46 mm，右上第一大臼齒的近心頰側尖端偏移量平均為1.76 mm。結論：本研究設計的正顎手術導板套組，能減少人為測量的誤差，縮短勒佛氏I型截骨術的操作時間及增加骨塊垂直和前後向定位的精準度。

Objective: To investigate the changes of the anatomical position of the bone Segments by three-dimensional simulation before and after the orthognathic surgery. Methods: In this study, CAD/CAM systems were used to analysis the relationship between preoperative and postoperative bony positions in 15 patients undergoing orthognathic surgery. Results: This study used CAD/CAM system surgical guides to plan the cutting lines. The average time to complete the Le Fort I osteotomy was 48 minutes. The average amount of bone segment deviation was 1.46 mm, and the average amount of deviation on the mesial buccal cusp tip of right upper first molar was 1.76mm. Conclusions: The surgical guide designed in this study can reduce the error resulted from manual measurement. Therefore, by using CAD/CAM system surgical guide technique, we can shorten the operation time of Le Fort I osteotomy and increase the accuracy of positioning of bone fragments.
