摘要/Abstract

摘要： 目的评价骨皮质切开辅助矫正舌倾磨牙的临床效果。方法选择单侧下颌第二恒磨牙舌倾的成人正锁牙合患者40例，分为两组，骨皮质切开组20例，用骨皮质切开术加交互牵引来矫正锁牙合。对照组20例，仅使用交互牵引来矫正锁牙合；观察两组患者锁牙合解除所用时间。两组患者分别在治疗前及治疗后拍摄CBCT，观察两组患者目标牙是否有牙根吸收情况。结果骨皮质切开组锁牙合解除的时间明显少于对照组；骨皮质切开组未发现明显的牙根吸收。结论采用骨皮质切开辅助矫正舌倾磨牙，能有效缩短矫治时间，同时也能减少牙根吸收等并发症。

Abstract: Objective To evaluate the effect of orthodontic treatment combined with the alveolar corticotomy surgery on the correction of lingual inclination of molars.Methods 40 patients with a unilateral scissors bite caused by lingual inclination of the second molar in mandible were divided into 2 groups （20 patients in each）.All of them were treated with intermaxillary elastics as to correct the scissors bite.20 patients were treated with the alveolar corticotomy surgery （Group 1）,and another 20 were in the control group without the alveolar corticotomy surgery （Group 2）.The treatment time of correcting the scissors bite in both groups was observed,and cone beam CT of root absorption before and after the treatment were compared.Results The treatment time was significantly shorter in G1 than in G2,and no obvious root absorption in G1 was detected.Conclusions Alveolar corticotomy surgery is effective in correcting the scissors bite in that it can shorten the treatment time and lower the occurrence of root absorption.
