中文摘要 | 垂直向的生長變異,常造成矯正治療困難度的增加,尤其是常見的高下 顎平面角的骨骼型態。為瞭解高下顎平面角患者的骨骼特徵,本研究選取11-12 歲的廣角群患者78位與均角群患者114位做測顱x光片的骨骼特徵比較。研究結果 顯示:高下顎平面角患者其骨骼變異主要在下顏面部位,包括下顏面高度增加、 �Z平面-下顎平面角增加及角點角增加,而上下前牙區對於下顏面高度的增加均 有代償性生長。此外,高下顎平面角患者的後顏面高度雖有明顯減少,但個體間 變異較大。 |
英文摘要 | Vertical malocclusion, especially high angleskeletal pattern, usually increases the complexity oforthodontic analysis and treatment plan. The pur-pose of this study was to compare the vertical char-acteristics between high angle skeletal pattem(SN-MP>37.5)and normal. The results show that thebasic dentofacial deformity of high angle skeletalpattern is focused on the lower face, such as in- creased LAFH, increased PP-MP angle and increased gonial angle. There is equal dento-alveolarcompensatory eruption in upper and lower anteriorregion. The posterior facial height of high anglegroup is smaller than normal angle group, but largeindividual variations exist. |
