摘要: 目的 评价颊腭侧微种植钉压低上颌伸长磨牙的临床效果。  方法 选择25名需要压低伸长磨牙(后续进行种植修复)的患者,利用微种植钉分别粘结在过长的磨牙颊舌两侧辅助加力进行压低。治疗前后拍摄头颅侧位定位片,进行头影测量分析比较。  结果 25名患者的30枚伸长磨牙均获得良好的压低正畸治疗效果,平均压低(2.52±0.76)mm,压低治疗的平均时间为(5.7±2.8)个月。  结论 应用微种植钉压低伸长磨牙,为长期缺失牙获得种植修复提供位置,是一种简单有效的正畸手段。

Abstract: Objective    To investigate the clinical effects of orthodontic microimplant nail  to suppress maxillary supra-erupted molar.   Methods   Twenty-five patients needed to depress and elongate molar (subsequent implantation and restoration) were selected. Mirco-implant nails were used to bone the over-long molars on palatal and buccal sides. Lateral cephalograms were taken at the beginning and the end of the treatment for cephalometric analysis and comparison.   Results    The supra-erupted molars of 25 patients were all successfully intruded with the average suppression depth of (2.52±0.76) mm, and the average duration of treatment was (5.7±2.8) months.   Conclusions     It is a simple and effective orthodontic method to lower the supra-erupted molar with a micro-implant nail, which can provide a position for the implanted restoration of long-term missing teeth.
