摘要
目的 观察口面肌功能治疗对安氏Ⅱ1类错（牙合）畸形的早期治疗效果.方法 选取2011年1月至2014年1月,我院口腔门诊进行肌功能治疗的患者14例,年龄7～12岁,男孩3例,女孩11例.其中替牙列11例,恒牙列3例,均为安氏Ⅱ1类错（牙合）,覆盖5.0～11.0 mm,其中Ⅲ度深覆（牙合）3例,均表现为牙列拥挤.进行肌功能评估后,选用不同型号的I2N训练器（Myofunctional Research Co.Queensland,Australia）,进行肌功能训练.应用SPSS19.0软件对治疗前后测量数据进行配对t检验.结果 6～10个月后,患者口周肌肉功能改善,深覆（牙合）、深覆盖纠正,牙列拥挤改善,面型改善.治疗后前牙覆盖减小（4.82±1.92） mm、覆（牙合）减小（2.25±0.64） mm、上切牙唇倾度减小（2.75±2.36） mm,6.96°±6.14°差异有统计学意义（P＜0.001）,下前牙唇倾度增加（-2.10°±2.90°）、SNB增加（-2.04°±2.29°）、FMA增加（-1.46°±1.75°）差异有统计学意义（P＜0.05）.结论 口面肌功能治疗简便、无创,对安氏Ⅱ1类错（牙合）的早期治疗是有效的,肌功能评估和训练是关键,疗效依赖于患者的良好配合.
Objective To clarify the effect of orofacial myofunctional therapy on early treatment of class Ⅱ 1 malocclusion.Methods 14 patients were selected,aged from 7＋3 to 12-1,with 3 boys and 10 girls.11 of them were mixed dentition and 3 were permanent dentition.The patients showed crowding,and the overjet ranged from 5.0 mm to 11.0 mm.3 of them presented with 100% overbite.All patients underwent orofacial myofunctional therapy with myofunctional appliances I2N （Myofunctional Research Co.Queensland,Australia）after myofunctional evaluation.Statistic analysis was done with SPSS19.0 software and paired t test was used.Results After 6-10 months,myofunction were improved,teeth were aligned,deep overjet and deep overbite corrected,and facial profile improved.The overjet [（4.82±1.92） mm],overbite [（2.25±0.64） mm] and proclination of the upper incisor [（2.75±2.36） mm,6.96°±6.14°] decreased after treatment and showed statistical significance （P〈0.001）.The inclination of lower incisor （-2.10°±2.90°）,SNB （-2.04°±2.29°） and FMA （1.46°± 1.75°） increased and showed statistical significance （P〈0.05）.Conclusions Orofacial myofunctional therapy was a noninvasive and easy way to treat class Ⅱ 1 malocclusion early.Myofunctional evaluation and exercises are the key points.It is important to have patients＆#39; good compliance.
