自攻种植钉垂直支抗矫治前牙开的临床分析

Clinical analysis on correcting anterior open(occlusion) with self-tapping screw planting vertical anchorage

目的临床分析自攻种植钉垂直支抗矫治前牙开的治疗效果。方法选择2007年3月至2011年1月在我院接受前牙开正畸治疗的患者15例,对其进行自攻种植微钛钉垂直支抗治疗,观察效果。结果所有患者治疗后的各个角度测量值更接近恒牙期正常值,60颗微钛钉种植体中有55颗稳固,成功率为91.67%。结论自攻微型钛钉种植体能作为稳定的骨性正畸支抗,值得在临床上推广。

Objective To analyze the effect of correcting anterior open （occlusion） with self - tapping screw planting vertical anchorage. Methods Fifteen cases suffered with anterior erossbite （occlusion） in this hospital during March 2007 to January 2011 were treated by self - tapping screw planting vertical anchorage, and their effectiveness was observed. Results After treatment, measurement of their teeth from various angle in all pateints was more close to normal permanent teeth, 55 of 60 micro -titanium screws were firmed, and the successful rate was 91.67%. Conclusion Titanium micro - implant self - tapping screw can stably anchor in orthodontic bone, and it is worthy to be recommended for clinical practice.
