- 中文摘要: 在測顱分析時,一個參考平面是否適當,乃在於它是否能準確的描述出生長或治療過程的變化。利用四十個經過齒科矯正的患者及三十個經臨床上判斷為具有理想咬合的人的顱顏規格攝影片來作分析,我們發現在兩種用來定義咬合平面的方法裡,唐氏咬合平面(DOP)可能是個較好的參考平面,因為它較能精確的指出矯正治療過程所產生的變化。 在探討像“咬合平面”如此複雜的問題之前,吾人須對咬合平衡的定義有較好的認知。在所有有關於此種平衡的因子完全被澄清之前,很難精確評估咬合平面。至於目前在測顱分析時廣為矯正醫師所使用的功能性咬合平面(FOP),它和咬合功能之間的關係無法在這個研究中獲得支持。
- 英文摘要: In this study an effort was made to determine which of the two commonly used methods of occlusalplane determination more precisely depicts changes induced by treatment or growth. Longitudinal lateralcephalometric radiographs of 70 individuals, 40 orthodontically treated and 30 with clinically acceptableocclusion, were used. Following an analysis of outcomes obtained through the conventional application ofthe Downs occlusal plane method and the functional occlusal plane method, there are indications that: 1)the Downs method may provide a better description of what happens to the occlusion following treatment;2) the notion that the plane reconstructed using the functional method actually represents the location atwhich the occlusal function takes place is unsubstantiated; and 3) since it is possible that the results of thisstudy could be influenced by the types of malocclusion, skeletal patterns, and methods of orthodontic treat-ment, further analyses are called for in order to make more conclusive determinations about these methods.
