摘要: 目的:探讨口唇肌训练配合Frankel Ⅲ型矫治器矫治替牙期Ⅲ类错𬌗畸形的临床疗效。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类错𬌗畸形儿童,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Frankel Ⅲ型矫治器矫治)和对照组各50例(采用Frankel Ⅲ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、Co-S、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Frankel Ⅲ型矫治器矫治替牙期Ⅲ类错𬌗畸形,更有利于纠正畸形,改善上气道形态,降低治疗后复发率。

Abstract: PURPOSE: To exploring the clinical effect of lip muscle training combined with Frankel Ⅲ orthodontic appliances in correcting Class Ⅲ malocclusion during the mixed dentition period. METHODS: One hundred children with Class Ⅲ malocclusion 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 Frankel Ⅲ orthodontic appliance) and a control group (treated with Frankel Ⅲ orthodontic 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 combination of lip muscle training and Frankel III orthodontic appliances is more conducive to correcting Class III malocclusion during the replacement period, improving upper airway morphology, and reducing the recurrence rate after treatment.
