目的：探讨自锁托槽矫治器在矫治错?畸形患者中的优缺点。方法对2010～2013年在广西壮族自治区人民医院口腔正畸科自愿选择自锁托槽进行矫治的10例（拔牙病例4例，不拔牙病例4例，推磨牙向远中1例，牙周病1例）错?畸形患者的治疗资料中有关治疗疗程、方法及疗效方面进行分析。结果10例患者矫治时间9～26（17±6.04）个月，矫治后上下?牙列排齐整平，磨牙关系及前牙覆?覆盖关系正常，牙尖窝及咬?关系良好。结论自锁托槽矫治器以其独特的结构降低了弓丝与托槽槽沟间的摩擦力，从而在轻力作用下使牙齿更为有效并迅速地排齐，缩短了矫治疗程，减轻患者疼痛感，是一种高效能的矫治器。

Objective To explore the advantages and disadvantages of self-ligating bracket appliance in the treatment of malocclusion patients .Methods The treatment information of 10 malocclusion patients had been treated voluntarily with self-ligating bracket appliance in department of orthodontics ,the People′s Hospital of Guangxi Zhuang Autonomous Region from 2010 to 2013 were collected and their treatment course ,method and effect were analyzed and summarised.Ten cases included 4 extracted cases,4 unextracted cases,one treated by moving molar distally and one having periodontopathy .Results The longest treatment course was 26 months,the shortest 9 months,average (17 ± 6.04)months.Dentitions were level and orderly.Overjet and overbite were normal range.Occlusion were compact. Conclusion Self-ligating bracket appliance has special structure and could reduce friction between arch and brack -et,so reduce drawing force .Teeth could be leveled fast .and orderly course of dentition was short .Pain during treat-ment was light .So self-ligating appliance was effective .
