MRC用于早期错牙合畸形阻断性矫治的效果分析(1)
摘 要：目的 探究MRC用于早期错牙合畸形阻断性矫治的临床效果。方法 选取2016年3月～2017年3月国药东风花果医院口腔科收治的儿童错牙合畸形患者33例纳入研究对象，对患者病因诊断明确，选取合适MRC，设计肌功能训练操，行早期阻断矫治，观察患者覆牙合，覆盖，以及下颌相对位置的改变，测量SNA，SNB，等指标，评价矫治效果。结果 本研究中错牙合畸形患儿利用MRC肌功能矫治器进行相应治疗后，前牙覆牙合、覆盖都得到明显纠正，面型得到改善，SNA，SNB等指标都得到了有效改变，治疗后头颅定位测量指标均优于治疗前，差异均有统计学意义(P<0.05)。结论 佩戴MRC并配合肌功能训练矫治儿童早期错牙合畸形效果显著，预防了功能损害性咬合障碍的发生，阻断患儿骨骼畸形发育，改善了患儿的颅面牙合功能及美观。

Abstract：Objective To investigate the clinical effect of MRC in the treatment of early malocclusion of blocking correction.Methods 33 children with malocclusion malocclusion who were treated in the Department of Stomatology of Dongfang Huaguo Hospital from March 2016 to March 2017 were included in the study.The diagnosis of the patient's etiology was clear.The appropriate MRC was selected and muscle function training exercises were designed to perform early blocking correction.Treatments were taken to observe occlusal and covering occlusions，change the relative position of the mandible，measure SNA，SNB，etc.，and evaluate the effect of correction.Results In this study，patients with malocclusion deformity were treated with MRC muscle function appliance.The anterior teeth and occlusal coverage were significantly corrected.The facial shape was improved.SNA，SNB and other indicators were effectively changed after treatment.The cephalometric measurements were superior to those before treatment，and the differences were statistically significant(P<0.05).Conclusion The use of MRC combined with muscle function training to treat early malocclusion in children is effective，preventing the occurrence of dysfunctional occlusal disorders，blocking the development of skeletal malformations in children，and improving the craniofacial occlusal function and appearance of children.

目前我國早期错颌畸形的发病率高达60%，但是由于家长对替牙的错误认识，加上传统的早期矫治借助的方法和工具比较复杂，未被广泛接受，早期阻断性治疗开展率并不高，普遍治疗延迟，从效果和经济费用上都造成了极大损失。早期矫治主要就是针对错牙合畸形发生的病因，机制以及发生与发展的过程开展的对症预防性治疗。它主要分为三个阶段：①预防：主要指去除病因，包括孕期错牙合畸形预防，治疗龋齿，乳牙早失等影响建立咬合的疾病等；②诱导：创建儿童建立良好咬合关系的口腔环境，包括序列拔牙，牙诱导性萌出等；③矫治：主要是针对已经发生的早期错牙合畸形，改善不良颅面结构，纠正不良咬合关系[1]。肌功能矫治器质地柔软、佩戴舒适、治疗周期短，适用于3～15 岁肌功能异常的错牙合畸形患者， 尤其对于青春期生长高峰前的儿童，使用方便，早期干预效果较好，本文旨在进一步探究MRC肌功能矫治器对儿童错牙合畸形的早期矫治疗效，为临床开展早期预防性矫治提供新的方法。, 百拇医药(吕娟 高子龙 朱有家)
