摘要:
目的：探究在替牙列期，对深覆牙合的患儿行MRC（Myofunctional research company）早期矫治后，其软组织及硬组 织的变化，评价MRC肌功能训练器对于深覆牙合病例的早期治疗效果，以期为深覆牙合病例的早期矫治提供依据。方法：回顾性 分析2019年12月-2020年8月于苏州大学附属口腔医院就诊的50例替牙期中重度牙性深覆牙合患儿的临床资料，早期应用MRC肌 功能训练器，比较其矫治前后硬组织及软组织变化，分析其前后改变的相关性。结果：治疗前后软组织测量值Z角，上唇E线 距，下唇E线距差异无统计学意义（P＞0.05），治疗前后硬组织测量值SNA、ANB、NP-FH、NA-PA、MP-FH、Y轴角、U1-L1、 U1-NA 、U1-NA、L1-MP、Po-NB距、FMA（FH-MP）差异均无统计学意义（P＞0.05）；治疗后，SNB、L1-NB、L1-NB均大于治疗 前，而覆牙合小于治疗前，差异均有统计学意义（P＜0.05）。结论：MRC肌功能训练器可显著减小替牙期患儿的中重度前牙深 覆牙合，同时可以增加下前牙唇倾度，改善下颌后缩。
Abstract:
Objective To study the changes of soft tissue and hard tissue of children with deep overbite after early correction of MRC (Myofunctional research company) in mixed dentition stage, and to evaluate the early treatment eff ect of MRC muscle function trainer for deep overbite cases, which can provide basis for early correction of deep overbite cases. Methods The clinical data of 50 children with severe deep overbite during mixed dentition who were treated in the affi liated stomatological hospital of Soochow University from December 2019 to August 2020 were retrospectively analyzed and used MRC muscle functional trainer in early stage. The paper compares the changes of hard tissue and soft tissue before and after treatment, and analyzes the correlation between the changes before and after treatment. Results There were no signifi cant diff erences in soft tissue Z Angle, upper lip E line distance and lower lip E line distance before and after treatment (P ＞0.05).Hard tissue SNA, ANB, NP-FH, NA-Pa , MP-FH, Y-axis Angle, U1-l1, U1-NA, U1-NA, L1-MP, Po-Nb distance, FMA(FH-MP) had no statistical signifi cance (P ＞0.05).After treatment, SNB, L1-NB, L1-NB were higher than before treatment, while overlap was lower than before treatment, the diff erences were statistically signifi cant (P ＜0.05). Conclusion MRC muscle function trainer can signifi cantly reduce deep overbite in children with deep overbite during tooth replacement, increase lip inclination of lower front teeth and improve mandibular retraction.
