1、兩種正頜手術(shù)方法治療骨性安氏III類錯(cuò)牙合穩(wěn)定性探究[摘要]目的:應(yīng)用計(jì)算機(jī)及WINCEPH軟件測(cè)量X線頭顱定位側(cè)位片,探討不同術(shù)式治療骨性安氏III類錯(cuò)牙合效果的穩(wěn)定性。方法:62例骨性安氏III類錯(cuò)牙合患者36例接受下頜升支矢狀劈開術(shù)(sagittalsplitramusosteotomy,SSRO),26例接受下頜升支垂直骨切開術(shù)(intraoralverticalramusosteotomy,IVRO),分別在手術(shù)前(T0)、手術(shù)后1個(gè)月(T1)、手術(shù)后6個(gè)月(T2)、手術(shù)后18個(gè)月以上(T3)拍攝頭顱定位側(cè)位片
