摘　　要：目的:比较无托槽隐形矫治器与Twin-Block矫治器治疗骨性安氏Ⅱ类1分类错牙合畸形患儿的效果。方法:选取2020年5月至2022年12月该院收治的80例骨性安氏Ⅱ类1分类错牙合畸形患儿进行前瞻性研究,按照随机数字表法将其分为观察组和对照组各40例。对照组采用Twin-Block矫治器治疗,观察组采用无托槽隐形矫治器治疗。比较两组临床疗效,治疗前后头影测量指标[上下齿槽座角(ANB)、下齿槽座角(SNB)、上齿槽座角(SNA)]水平、错牙合畸形严重程度[同行评估等级指数(PAR)]评分和口腔功能评分。结果:观察组治疗总有效率为92.50%(37/40),高于对照组的75.00%(30/40),差异有统计学意义(P<0.05);治疗后,两组ANB、SNA均小于治疗前,且观察组小于对照组,两组SNB均大于治疗前,且观察组大于对照组,差异有统计学意义(P<0.05);治疗后,两组PAR评分均低于治疗前,且观察组低于对照组,差异有统计学意义(P<0.05);治疗后,两组咀嚼功能、美观度等口腔功能评分均高于治疗前,且观察组高于对照组,差异有统计学意义(P<0.05)。结论:无托槽隐形矫治器治疗骨性安氏Ⅱ类1分类错牙合畸形患儿可提高治疗总有效率和口腔功能评分,改善头影测量指标水平,降低错牙合畸形严重程度评分,效果优于Twin-Block矫治器治疗。Objective:To compare effects of bracketless invisible appliance and Twin-Block appliance in treatment of children with skeletal Angle’s Class II Division 1 malocclusion.Methods:A prospective study was conducted on 80 children with skeletal Angle’s Class II Division 1 malocclusion admitted to this hospital from May 2020 to December 2022.According to the random number table method,they were divided into observation group and control group,40 cases in each group.The control group was treated with Twin-Block appliance,while the observation group was treated with bracketless invisible appliance.The clinical efficacy,the levels of cephalometric indexes[angle between A point and B point(ANB),sella nasion B point angle(SNB),sella-nasion-A point angle(SNA)],the malocclusion severity[peer assessment rating index(PAR)]scores,and the oral function scores were compared between the two groups before and after the treatment.Results:The total effective rate of the observation group was 92.50%(37/40),which was higher than 75.00%(30/40)of the control group,and the difference was statistically significant(P<0.05).After the treatment,the ANB and SNA levels of the two groups were smaller than those before the treatment,and those in the observation group were smaller than those in the control group;the SNB levels of the two groups were greater than those before the treatment,and that in the observation group was greater than that in the control group;and the differences were statistically significant(P<0.05).After the treatment,the PAR scores of the two groups were lower than those before the treatment,that in the observation group was lower than that in the control group,and the differences were statistically significant(P<0.05).Further,after the treatment,the scores of oral function such as chewing function and aesthetics in the two groups were higher than those before the treatment,those in the observation group were higher than those in the control group,and the differences were statistically significant(P<0.05).Conclusions:Br
