微型种植体支抗在口腔正畸治疗中的临床应用评价

目的探讨微型种植体支抗在口腔正畸治疗中的疗效。方法回顾性分析2008年3月－2011年10月我科收治的60例正畸治疗患者，实验组微型种植体支抗治疗（n=30），非对照组种植体支抗治疗（n＝30）。观察两组患者治疗后上中切牙倾角差、上中切牙凸距差及磨牙位移差异。结果较之对照组，实验组患者上中切牙倾角差和上中切牙凸距差明显较大（P〈0．01）；而磨牙位移明显较对照组磨牙异位小（P〈0．01），患者满意度高。结论微型种植体支抗操作简便，正畸治疗效果理想。

Evaluation on clinical application of micro-implant anchorage in orthodontic treatment

Objective To investigate the efficacy of micro-implant anchorage in orthodontic treatment. Methods 60 cases admitted from March 2008 to October 2011 orthodontic patients, were divided into experimental group （n=30） and control group （n=30）. Incisor inclination difference comparative analysis was observed between the upper central incisors protruding length difference and molar displacement. Results Compared with the control group, the experimental group patients in incisor inclination difference and the upper central incisors prodding length difference were significantly greater （P〈0.01）; molar displacement was smaller （P〈0.01）, with high satisfaction of patients. Conclusions The micro-implant anchorage is simple for operation, orthodontic treatment results are satisfactory.
