摘要
目的探讨下颌前倾、水平阻生磨牙的正畸治疗方法，评估其效果。方法采用固定矫治器结合磨牙带环焊多曲推簧，推14颗水平阻生或前倾阻生的下颌磨牙远中向、[牙合]向移动，引导其竖直、萌出。结果前倾、水平阻生的下磨牙全部竖直萌出到正常的[牙合]平面并有良好的[牙合]接触关系。X线片显示原阻生牙牙冠所占位置被正常牙槽骨组织所代替。竖直治疗时间为6～12个月，平均7．4个月。结论带环焊多曲推簧的磨牙竖直技术能有效地使前倾、水平阻生的下颌磨牙产生快速的远中向、[牙合]向旋转运动，具有创伤小、操作简单、患者易适应等优点。
Objective To assess the treatment method and outcome of mesially or horizontally impacted mandibular molars. Methods Eleven patients with mandibular impacted molars, including 9 horizontally impacted molars and 5 mesially impacted molars were treated with fixed appliance in conjunction with molar band soldered with pushing spring. Crowns of impacted molars were moved occlusally and distally. Results All mesially or horizontally mandibular impacted molars were uprighted and brought into occlusion. Mean treatment period was 7, 4 months （6 to 12 months）. Conclusions This orthodontic molar uprighting technique was effective in uprighting and distalizing the impacted molars.
