目的：：探讨直丝弓矫正技术两种支抗方法矫治安氏I类双颌前突畸形的效果。方法：选取60例安氏Ⅰ类双颌前突畸形患者，均采用MBT直丝弓技术矫治，其中30例使用J钩支抗，标记为对照组，另外30例使用种植体支抗，标记为治疗组，对比两组矫治前后的X线投影情况和治疗时间。结果：对照组和治疗组的U6C-PP值比较结果具有统计学意义(P<0.01)，其他指标均无统计学意义(P>0.05)。对照组平均治疗时间为(26.2±3.6)个月，治疗组的平均治疗时间为(23.4±2.7)个月，对照组长于治疗组，结果具有统计学意义(P<0.05)。结论：种植体支抗操作简单有效，提升了患者的舒适度，在临床上有一定的指导意义。

Objective:To investigate the straight wire technique two anchorage method in the treatment of angle classⅠbimaxillary protrusion deformity.Methods:60 patients with angle class Ⅰ bimaxillary protrusion patients,were treated with MBT straight wire appliance,including 30 cases of the use of J hook anchorage,marked as control group,another 30 cases using implant anchorage,marked as treatment group,the X-ray projection and compared before and after treatment in two groups during treatment between.Results:The treatment group and the control group in the U6C-PP values comparison results with statistical significance (P<0.01),the other indexes had no statistical significance (P>0.05).Control group the average treatment time was (26.2±3.6) months,the average treatment time of treatment group was (23.4±2.7) months,the control group in the treatment group,the results were statistically significant (P<0.05). Conclusion:The implant anchorage operation is simple and effective,improve patient comfort,has a certain significance in clinical.
