摘要 目的:分析高转矩自锁托槽矫正治疗双颌前突患者的效果及对上颌切牙正畸性根尖外吸收的影响。方法:在2017年1月至2020年12月期间到武警河南总队医院口腔科开展矫正治疗的双颌前突患者中抽取60例纳入研究,根据矫治手段的不同将所有患者分为对照组和观察组,各30例。对照组利用传统直丝弓托槽进行治疗,观察组利用高转矩自锁托槽进行治疗,比较两组患者的正畸效果、治疗时间、上颌切牙的根尖外吸收量、矫治不良反应发生率。结果:两组患者接受矫正治疗的总有效率均较高且治疗期间均未发生严重的不良反应,组间比较,差异无统计学意义(P>0.05);观察组患者的治疗时间短于对照组患者,且上颌中切牙、上颌侧切牙的根尖外吸收量均显著更少,差异具有统计学意义(P<0.05)。结论:高转矩自锁托槽矫治双颌前突患者的临床效果突出,相对于传统直丝弓托槽治疗,能够进一步缩短矫正疗程、降低正畸性根尖外吸收的风险,生物相容性较高。
