1、山東大學(xué)碩士學(xué)位論文及上唇一審美平面距UL．E(mm)明顯增加，上下唇交角A’UL—B’LL明顯減??；下唇基角SN’B'、下唇傾角B’LL．FH、下唇頦突角LL-N'-Pos及下唇一審美平面距LL．E均減??；3．前牙軸傾度：上前牙唇傾，下前牙舌傾，U1．SN角、Ul-NA角及Ul小jA距均明顯增大，L1-NB距減?。?．牙弓寬度：上頜慢速擴(kuò)弓后，恒牙晚期UCLP患者牙群模型三組樣本第一前磨牙間寬度4-4、第一前磨牙舌尖間距離4‘一4’及第二前磨牙間寬度5．5數(shù)值在治療前、擴(kuò)弓結(jié)束后及保持半年后的差異有統(tǒng)計(jì)學(xué)意義，而且保持效果差異有統(tǒng)計(jì)學(xué)意義，●第
2、一磨牙間寬度6．6三組樣本的差異無(wú)統(tǒng)計(jì)學(xué)意義，上頜尖牙間寬度3．3數(shù)值在擴(kuò)弓前后差異有統(tǒng)計(jì)學(xué)意義，但擴(kuò)弓后與保持半年后的差異無(wú)統(tǒng)計(jì)學(xué)意義。即正畸治療后，尖牙區(qū)和前磨牙區(qū)的牙弓寬度有明顯增加，前磨牙區(qū)擴(kuò)弓效果比較穩(wěn)定，但基骨弓與牙槽弓的寬度變化無(wú)統(tǒng)計(jì)學(xué)差異。結(jié)論：恒牙晚期UCLP術(shù)后患者經(jīng)正畸治療，骨骼、面部軟硬組織及咬合關(guān)系均有較理想的治療效果。通過(guò)上頜慢速擴(kuò)弓聯(lián)合固定矯治，上頜骨矢狀面發(fā)生前移，上頜牙弓寬度增加，下頜骨未見(jiàn)顯著的變化，咬合關(guān)系得到有效改善，同時(shí)患者軟組織側(cè)貌有明顯改善，表現(xiàn)為凹面型趨向于直面型，上唇凸度增加，上唇變飽滿(mǎn)，下唇外翻
