摘　　要：目的探讨LF托槽和传统托槽临床矫治安氏Ⅰ类错畸形效率的差异。方法选取我院2013年5月至2014年5月期间收治的安氏Ⅰ类错患者40例,均为恒牙期病例,随机分为观察组和对照组各20例。观察组应用LF托槽-低摩擦轻力滑动托槽治疗,对照组应用直丝弓常规矫治技术的传统托槽治疗。分析和比较两组在排齐牙列阶段与关闭间隙阶段的总疗程时间、总复诊次数、托槽的总脱落率、复诊间隔时间和下切牙的牙龈指数,并观察记录两组在矫正过程的不良反应发生率。结果观察组患者在排齐牙列阶段与关闭间隙阶段的总疗程时间、总复诊次数、托槽的总脱落率和复诊间隔时间均显著少于对照组(P<0.05);观察组排齐牙列阶段与关闭间隙阶段下切牙的牙龈指数显著低于对照组(P<0.05);观察组的不良反应发生率为5.0%(1例),显著低于对照组的30.0%(6例),P<0.05。结论 LF托槽矫治安氏Ⅰ类错畸形可以有效缩短总疗程时间,提高矫正疗效,降低矫正过程的不良反应发生率,值得临床推广。Objective To explore the difference of clinical efficiency between LF-bracket and traditional bracket in the correction ofclass I malocclusion. Methods 40 cases of patients with class [ malocclusion admitted to our hospital from May 2013 to May 2014 wereselected and randomly divided into observation group and control group, with 20 cases in each group. All the cases were permanent teeth.The observation group was treated with LF-bracket with low friction and light force, while the control group was treated with traditionalbracket with straight wire. The total treatment time, total times of return visit, total shedding rate of bracket, interval of return visit andgingival index of lower incisors during the stage of teeth aligning and space closing were analyzed and compared between two groups. Theincidence of adverse reactions during the correction of two groups were observed and recorded. Results The total treatment time, total timesof return visit, total shedding rate of bracket and interval of return visit during the stage of teeth aligning and space closing of observationgroup were all significantly less than those of control group （P 〈0.05）. The gingival index of lower incisors during the stage of teeth aligningand space closing of observation group was significantly lower than that of control group （P〈0.05）. The incidence of adverse reactions ofobservation group was 5.0% （1 case）, significantly lower than 30.0% （6 cases） of control group （P〈0.05）. Conclusions LF-bracket in thecorrection of class I malocclusion can significantly reduce the total treatment time, improve the correction effect and reduce the incidenceof adverse reactions during the correction, which is worthy clinical promotion.
