Treatment effects of reverse-headgear in correction of Angle Class III malocclusion

2010
目的　分析替牙期前方牽引器矯治安氏Ⅲ類錯前牙反中骨性和牙性變化。方法　選擇2 0例安氏Ⅲ類錯前牙反患者 ,在替牙早期使用前方牽引器 ,治療開始、治療結束及治療結束后一年拍攝頭頗側位片 ,并以Pancherz分析法進行頭影測量分析。結果　表明 ,在治療剛剛結束時 ,覆蓋增加 6 5毫米 ,其中 40 %為骨性變化 ,6 0 %為牙性代償。治療結束后一年發現覆蓋減少 1 2毫米 ,即骨性變化占 2 3% ,牙性代償 77%。覆蓋減少的原因為下頜向前生長和下切牙唇傾.
