摘　　要：目的比较SanderⅡ和Forsus两种功能矫治器治疗生长发育期下颌后缩患者的临床疗效。方法选择生长发育期下颌后缩男女患者26例,随机分为SanderⅡ(S)和Forsus(F)两组,每组各13例患者(男6例和女7例)。测量治疗前、后摄X线头侧位片,并对相关的软硬组织指标进行统计学分析。结果硬组织测量指标中,两组矫治器治疗前、后,SNB、Y轴角、B-OLP距、Ii-OLP距显著增加。ANB角、覆盖显著减小。F组的LI-MP有显著增加。S组的SN-MP、Ans-Me(下面高)有显著增加。软组织测量指标中,两组治疗前后软组织面角,鼻唇角,颏厚有显著增加,H角、上唇-审美平面距、下唇-审美平面距显著减小。S组的治疗总疗程较F组长。结论两种矫治器对下颌后缩患者均有较好的矫治作用,SanderⅡ矫治器适于低角以及均角病例,Forsus矫治器更适于高角病例,易导致下前牙易唇倾,但治疗疗程相对较短。Objective To compare SanderⅡand Forsus appliance in mandible retrusion.Methods Twenty-six patients with mandible retrusion were recruited and randomly divided into two groups：SanderⅡ group（S） and Forsus group（F）,each group consisting of 6 boys and 7 girls.Cephamatric radiographs were taken before and after treatment in order to compare changes in the hard and soft tissue.Results SNB,Y axis angle,B-OLP,Ii-OLP,soft-tissue facial angle,Cm-Sn-Ls and the thickness of chin increased significantly in both groups.In contrast,ANB、overjet,H angle、Ls-E line、Li-E line decreased significantly.LI-MP increased significantly in F group,while SN-MP and Ans-Me increased significantly in S group.Course of treatment in S group were shorter than those of F group.Conclusions Both appliances could effectively correct mandible retrusion.SanderⅡwas more applicable to patients at low or normal facial angle,while Forsus was more applicable to patients at high angle.Mandible incisors were susceptible to labially movement with Forsus appliance,however,its course of treatment could be shortened.
