摘　　要：目的:研究自锁托槽与普通托槽对安氏I类重度拥挤患者牙根吸收的影响。方法:回顾性选择2006年6月-2012年10月在温州医科大学附属口腔医院正畸科完成治疗的患者70例,分为自锁托槽组(35例,Damon3 0.022"bracket)和普通托槽组(35例,0.022"3M bracket)。治疗前后由同一人、相同仪器、相同设置拍摄全景片。分别测量上下前牙的牙根吸收程度。采用SPSS11.0进行统计学分析。结果:自锁托槽和普通托槽对牙根吸收的影响差异无统计学意义(P>0.05)。但是自锁托槽组轻度牙根吸收的患者多于普通托槽组。结论 :自锁托槽与普通托槽对安氏I类牙列重度拥挤患者的牙根吸收没有差别。Objective： To investigate the effect of self-ligating and in the apical root conventional brackets on root resorption in severe anterior crowding Class I patients after orthodontic treatment. Methods： Seventy subjects who completed orthodontic treatment in Orthodontic of Hospital Stomatology, Wenzhou Medical Uni- versity from 2006 to 2012 were divided into two group： self-ligating group （35 subjects treated with the Damon3 0.022＂ bracket） and conventional group （35 subjects with the 0.022＂ 3M bracket）. Quantitative measurements of crown and root lengths for the maxillary and the mandibular central and lateral incisors in the same person were used with the same machine and similar set up. Means and standard deviations for the percentage root resorption per tooth group were calculated by SPSS11.0. Results： No statistically significant difference in root resorption between the two appliance systems was found. The less root resorption observed in self-ligating group was more than that in the conventional group. Conclusion： There is no significant difference in root resorption between self-ligating brackets and conventional brackets in severe crowding incisors subjects.
