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。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.
