摘　　要：目的:探讨口唇肌训练配合FrankelⅢ型矫治器矫治替牙期Ⅲ类错[牙合]畸形的临床疗效。方法:选择杭州绿城口腔医院2018年6月-2022年12月收治的100例替牙期Ⅲ类错[牙合]畸形儿童,采用随机数字表法将患儿分为联合组(采用口唇肌训练配合FrankelⅢ型矫治器矫治)和对照组各50例(采用FrankelⅢ型矫治器矫治)。比较2组患儿治疗前后X线头影测量指标、颞下颌关节参数、上气道测量值参数及12个月后的随访情况。采用SPSS 21.0软件包对数据进行统计学分析。结果:治疗前,联合组和对照组SNA、SNB、ANB、U1-NA、L1-NB、ANS-Ptm、S-Ptm、Co-Po、CoS、MP-SN、MP-FH和NP-FH相比,差异无统计学意义(P>0.05);治疗后,联合组ANB、U1-NA、L1-NB和MP-SN大于对照组,NP-FH小于对照组,差异有统计学意义(P<0.05)。治疗前,联合组和对照组关节上间隙、前间隙和后间隙相比,差异无统计学意义(P>0.05);治疗后,联合组关节上间隙、后间隙大于对照组,差异有统计学意义(P<0.05)。治疗前,联合组和对照组Ba-PNS、Ad1-PNS、Ad2-PNS、Mc1-Mc2、SPP-SPPW、U-MPW、PAS和V-LPW相比,差异无统计学意义(P>0.05);治疗后,联合组Ad2-PNS大于对照组,差异有统计学意义(P<0.05)。随访12个月,联合组复发率为2.00%,显著低于对照组的16.00%(P<0.05)。结论:口唇肌训练配合FrankelⅢ型矫治器矫治替牙期Ⅲ类错[牙合]畸形,更有利于纠正畸形,改善上气道形态,降低治疗后复发率。PURPOSE:To exploring the clinical effect of lip muscle training combined with FrankelⅢorthodontic appliances in correcting ClassⅢmalocclusion during the mixed dentition period.METHODS:One hundred children with ClassⅢmalocclusion during the mixed dentition period admitted to Hangzhou Greentown Stomatological Hospital from June 2018 to December 2022 were selected.The children were randomly divided into a combination group(treated with lip muscle training and FrankelⅢorthodontic appliance)and a control group(treated with FrankelⅢorthodontic appliance),with 50 cases in each group.X-ray cephalometric indicators,temporomandibular joint parameters,upper airway measurement parameters and 12 month follow-up of the two groups of children were compared before and after treatment.SPSS 21.0 software package was used for statistical analysis.RESULTS:Before treatment,there was no significant difference of SNA,SNB,ANB,U1-NA,L1-NB,ANS-Ptm,S-Ptm,Co Po,Co-S,MP-SN,MP-FH and NP-FH between the combination group and the control group(P>0.05).After treatment,ANB,U1-NA,L1-NB and MP-SN in the combination group were significantly higher than those in the control group,while NP-FH were significantly lower than that in the control group(P<0.05).Before treatment,there was no significant difference of the joint space,anterior joint space and posterior joint space between the combination group and the control group patients(P>0.05);after treatment,the joint space and the joint space in the combination group were significantly higher than those in the control group(P<0.05).Before treatment,there was no significant difference of Ba PNS,Ad1 PNS,Ad2 PNS,Mc1 Mc2,SPP-SPPW,U-MPW,PAS and V-LPW between the combination group and the control group(P>0.05);after treatment,Ad2-PNS in the combination group was significantly higher than that in the control group(P<0.05).After 12 months of follow-up,the recurrence rate of the combination group was 2.00%,which was significantly lower than that(16.00%)of the control group(P<0.05).CONCLUSIONS:The combin
