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。
