微種植體支抗輔助透明矯治器遠(yuǎn)移下頜磨牙的三維測量分析微種植體支抗輔助透明矯治器遠(yuǎn)移下頜磨牙的三維測量分析

摘要：背景：在正畸治療中，遠(yuǎn)距離移動(dòng)下頜磨牙是一項(xiàng)有挑戰(zhàn)性的任務(wù)。微種植體支抗輔助透明矯治器已經(jīng)在遠(yuǎn)距離移動(dòng)下頜磨牙方面取得了良好的療效。本文的目的是通過三維測量分析評(píng)估微種植體支抗輔助透明矯治器遠(yuǎn)移下頜磨牙的療效。

方法：本研究共納入20名患者，采用微種植體支抗輔助透明矯治器治療下頜磨牙遠(yuǎn)移。在治療前后采用三維測量儀器對(duì)下頜磨牙進(jìn)行測量，包括三維坐標(biāo)、角度和距離等指標(biāo)。通過統(tǒng)計(jì)分析這些指標(biāo)的變化情況，評(píng)估微種植體支抗輔助透明矯治器遠(yuǎn)移下頜磨牙的療效。

結(jié)果：研究結(jié)果顯示，經(jīng)過微種植體支抗輔助透明矯治器治療后，下頜磨牙的位置和姿態(tài)均有明顯變化。其中，磨牙的遠(yuǎn)中移動(dòng)距離約為2.64mm，磨牙的垂直移動(dòng)距離約為1.22mm。此外，磨牙的傾斜角度也有顯著減小。

結(jié)論：微種植體支抗輔助透明矯治器可以有效地促進(jìn)下頜磨牙的遠(yuǎn)移。通過三維測量分析，我們能夠客觀地評(píng)估微種植體支抗輔助透明矯治器治療下頜磨牙遠(yuǎn)移的療效。這項(xiàng)研究為尋求更加有效的下頜磨牙遠(yuǎn)移正畸治療方法提供了一定的理論支持。
