摘　　要：目的分析微创骨皮质切开术应用于成人患者拔牙正畸治疗的效果。方法前瞻性随机选取2021年9月—2022年8月福建医科大学附属泉州第一医院收治的80例拔牙正畸患者为研究对象,根据治疗方式的差异分组,每组40例。观察组接受微创骨皮质切开术辅助正畸治疗,对照组接受常规拔牙正畸治疗,对比两组患者牙列排齐整平时间、间隙关闭时间、上颌第二磨牙向中间位置移动的距离、牙根吸收量。结果观察组的牙列排齐整平时间及间隙关闭时间均短于对照组,差异有统计学意义(P均<0.05)。治疗后1个月、2个月、3个月观察组的上颌第二磨牙向中间位置的移动距离优于对照组,差异有统计学意义(P均<0.05)。治疗前,两组牙根吸收量比较,差异无统计学意义(P>0.05)。治疗3个月后,观察组的牙根吸收量为(0.48±0.07)mm,低于对照组的(1.02±0.13)mm,差异有统计学意义(t=23.131,P<0.05)。结论微创骨皮质切开术应用于成人拔牙正畸治疗时,患者牙列排齐整平时间及间隙关闭时间均更短,治疗后上颌第二磨牙向中间位置移动的距离更长,牙根吸收量更低。Objective To analyze the effect of minimally invasive corticotomy-assisted orthodontic treatment of adult patients with tooth extraction.Methods From September 2021 to August 2022,80 orthodontic patients with tooth extraction admitted to Quanzhou First Hospital Affiliated to Fujian Medical University were prospective randomly selected as the research objects.According to the difference of treatment methods,they were divided into groups,with 40 cases in each group.The observation group received minimally invasive corticotomy-assisted orthodontic treatment,and the control group received conventional tooth extraction orthodontic treatment.The time of dentition alignment and leveling,the time of gap closure,the distance of maxillary second molar moving to the middle position,and the amount of root resorption were compared between the two groups.Results The time of dentition alignment and clearance closure in the observation group were shorter than those in the control group,and the differences were statistically significant(both P<0.05).The movement distance of the maxillary second molar to the middle position in the observation group was better than that in the control group at 1 month,2 months and 3 months after treatment,and the differences were statistically significant(all P<0.05).Before treatment,there was no significant difference in root resorption between the two groups(P>0.05).After 3 months of treatment,the root resorption of the observation group was(0.48±0.07)mm,which was lower than that of the control group(1.02±0.13)mm,and the difference was statisti cally significant(t=23.131,P<0.05).Conclusion When minimally invasive corticotomy is applied to orthodontic treat ment of adult tooth extraction,the time of dentition alignment and clearance closure is shorter,and the distance of maxillary second molar moving to the middle position is longer after treatment,and the root resorption was lower.
