摘　　要：目的:比较Twin-block矫治器与无托槽隐形矫治器治疗安氏Ⅱ类1分类错[牙合]下颌后缩患者的疗效。方法:选取2018年1月-2022年12月笔者科室就诊的100例安氏Ⅱ类1分类错[牙合]下颌后缩患者,采用随机数字表法分为隐形组与Twin-block组,每组50例。隐形组采用无托槽隐形矫治器治疗,Twin-block组采用Twin-block矫治器治疗,比较两组矫治效果。结果:Twin-block组矫治时间为(8.95±1.48)个月,长于隐形组的(7.15±2.55)个月(P<0.05)。治疗后,两组SNA、ANB、U1-NA角、U1-SN角、U1-NA距均小于治疗前,SNB、L1-NB距、Go-Gn、Ar-Go大于治疗前,且治疗后Twin-block组的Go-Gn、Ar-Go大于隐形组(P<0.05)。治疗后,两组H-NP、H-CVP、H-PP、H-Or、H-MP、H-PNS、H-FH测量数值均大于治疗前(P<0.05),且Twin-block组的H-FH大于隐形组(P<0.05)。治疗后,两组SPP-SPPW、PNS-Ba、Mc1-Mc2、U-MPW、V-LPW测量数值均大于治疗前(P<0.05),且Twin-block组的PNS-Ba大于隐形组(P<0.05)。治疗前,两组覆盖、覆[牙合]、颏沟倾角、鼻唇角、颏软组织厚度比较,差异无统计学意义(P>0.05);治疗后,两组覆盖、覆[牙合]均小于治疗前,颏沟倾角、鼻唇角、颏软组织厚度均大于治疗前(P<0.05),且Twin-block组的覆盖、覆[牙合]小于隐形组,颏沟倾角、鼻唇角、颏软组织厚度大于隐形组(P<0.05)。结论:安氏Ⅱ类1分类错[牙合]下颌后缩采用Twin-block矫治器与无托槽隐形矫治器治疗均有一定效果,Twin-block矫治器在改善舌骨位置及上气道矢状径、面容美观性方面前置效果更明显,但所需矫治时间相对稍长。Objective To compared treatment efficacy between Twin Twin-block appliance and Non-bracket invisible orthodontic appliance without bracket for patients with angle classⅡmalocclusion mandibular retraction.Methods 100 cases patients with angle classⅡ^(1) malocclusion mandibular retraction in the hospital from January 2018 to December 2022,according to the random number table method,they were divided into invisible group and Twin-block group,with 50 cases in each group.The invisible group was treated with non-bracket invisible orthodontic appliance,and the Twin-block group was treated with Twin-block appliance.The treatment efficacy were compared before and after treatment.Results The treatment time in the Twin-block group was(8.95±1.48)months,which was longer than that in the invisible group(7.15±2.55)months,the difference was statistically significant(P<0.05).There was no statistically significant difference in SNB,SNA,ANB,U1-NA angle,U1-SN angle,L1-NB distance,U1-NA distance,Go-Gn,A-Go between the two groups before treatment(P>0.05),after treatment,the SNA,ANB,U1-NA angle,U1-SN angle,and U1-NA distance of the two groups were all smaller than before treatment,while the SNB,L1-NB distance,Go-Gn,and Ar-Go were larger than before treatment,the Go-Gn and Ar-Go levels in the Twin-block group were higher than those in the invisible group,the difference was statistically significant(P<0.05).There was no statistically significant difference in H-NP,H-CVP,H-PP,H-Or,H-MP,H-PNS,and H-FH between the two groups before treatment(P>0.05),the measured values after treatment in both groups were greater than before treatment,H-FH in the Twin-block group were higher than those in the invisible group,the difference was statistically significant(P<0.05).There was no statistically significant difference in SPP-SPPW,PNS-Ba,Mc1-Mc2,U-MPW,and V-LPW between the two groups before treatment(P>0.05),the measured values after treatment in both groups were greater than before treatment,PNS-Ba in the Twin-block group were higher than those
