摘　　要：目的对比Pass矫治器与Twin-block功能矫治器联合自锁托槽在安氏Ⅱ类1分类错[牙合]畸形中的矫正效果。方法选取2020年2月—2022年5月在彭州市中医医院就诊的安氏Ⅱ类1分类错[牙合]畸形患者72例,采用随机数字表法将其分成研究组和对照组,每组36例。对照组接受Twin-block功能矫治器联合自锁托槽治疗,研究组接受Pass矫治器治疗。对比两组临床疗效、颌牙排齐时间、硬组织头影测量指标[上中切牙轴与蝶鞍中心-鼻根点平面夹角(U1-SN)、下中切牙轴与鼻根点-上齿槽座点连接角(U1-NA)、上齿槽座点、鼻根点及下次槽座点连接角(ANB)、蝶鞍中心、鼻根点及上齿槽座点连接角(SNA)]、软组织头影测量目标[上唇到审美平面距离(TUL-FP)、下唇H线距、下唇到审美平面距离(TLL-FP)、鼻唇角]、矫治效果及患者满意度。结果研究组总有效率高于对照组(P<0.05)。研究组上颌牙排齐时间和下颌牙排齐时间均短于对照组(P<0.05)。两组治疗前后U1-SN、ANB、SNA、SNB的差值比较,差异无统计学意义(P>0.05)。研究组治疗前后U1-NA的差值高于对照组(P<0.05)。研究组治疗前后下唇H线距、TUL-FP、鼻唇角、TLL-FP的差值高于对照组(P<0.05)。研究组治疗前后同行评估等级指数(PAR)评分的差值高于对照组(P<0.05)。研究组满意度高于对照组(P<0.05)。结论相比于Twin-block功能矫治器联合自锁托槽,Pass矫治器治疗安氏Ⅱ类1分类错[牙合]畸形患者效果确切,可提高矫治效果,改善面部侧貌美学,缩短颌牙排齐时间,且患者满意度较高。Objective To compare the correction effect of the PASS appliance and the Twin-block functional appliance combined with self-ligating bracket for Angle Class II,Division 1 malocclusions.Methods From February 2020 to May 2022,a total of 72 patients with Angle Class II,Division 1 malocclusions in our hospital were selected.They were divided into the study group(n=36)and the control group(n=36)by the random number table method.The control group received treatment with Twin-block functional appliance combined with self-ligating bracket,and the study group was treated with the PASS appliance.The clinical efficacy,teeth alignment time,hard tissue cephalometric measurements[Upper Incisor to Sella-Nasion angle(U1-SN),Upper Incisor to Nasion-A point angle(U1-NA),A point-nasion-B point angle(ANB),Sella-Nasion to A point angle(SNA)],soft tissue cephalometric measurements[upper lip to esthetic plane distance(TUL-FP),lower lip H-line distance,lower lip to esthetic plane distance(TLL-FP),nasolabial angle],correction effect and patient satisfaction were compared between the two groups.Results The overall effective rate of the study group was higher than that of the control group(P<0.05).The maxillary and mandibular teeth alignment time in the study group were shorter than those in the control group(P<0.05).The differences of U1-SN,ANB,SNA and SNB before and after treatment were not different between the two groups(P>0.05).The difference of U1-NA before and after treatment in the study group was higher than that in the control group(P<0.05).The differences of lower lip H-line distance,TUL-FP,nasolabial angle and TLL-FP before and after treatment in the study group were higher than those in the control group(P<0.05).The difference of peer assessment rating(PAR)index before and after treatment was higher in the study group than in the control group(P<0.05).The satisfaction of the study group was higher than that of the control group(P<0.05).Conclusions Compared with the Twin-block functional appliance combined with self-ligating br
