摘要

本研究針對80位安格氏二級第一分類合併深咬患者，以及80位一級咬合具正常覆咬者為對照組來進行顱顏齒顎形態分析。研究方法使用其側面測顱X光片，進行測量項目的Student's t-test，另外以2-wsy ANOVA來探討上下顎交角角度次分組之間是否存在顯著差異。結果發現安格氏二級第一分類異常咬合合併深咬成年男性的角點角與下角點角顯著較小，成年女性的上角點角顯著較小，前顏面高度與前下顏面高度均較大；上下顎交角角度越大，則角點角、上角點角與下角點角就有顯著越大的情形；上顎前牙齒槽高度與下顎前牙齒槽高度均較大。

Lateral cephalograms of eighty adults of Angle Class Ⅱ division 1 malocclusion with deep overbite compared with eighty adult with normal occlusion. Before the undergoing of the Student's t-test and 2-way ANOVA of the measurements of dentofacial morphology, the depth of the vertical overbite between Class Ⅱ division 1 with deepbite malocclusion and normal occlusion were compared firstly to confirm that there is significant difference in the depth of the anterior overbite. There is some significant difference in the dentofacial morphology between the adult of Class Ⅱ division 1 with deep-bite malocclusion and the adult of normal occlusion. Smaller gonial angle and lower gonial angle in male, smaller upper gonial angle, larger anterior facial height and lower anterior facial height in female. Due to supra-eruption of the anterior teeth, larger upper anterior dentoalveolar height and lower anterior dentoalveolar height were found.
