微型种植钉支抗在口腔正畸中的应用研究

Research on Application of Mini-implant Anchorage in Orthodontics

目的探讨分析在口腔正畸中采用微型种植钉支抗的临床效果。方法方便选取该院2010年1月—2017年1月收治的80例口腔正畸患者,随机分为两组,即对照组和实验组,对照组采取口外弓强支抗治疗,而实验组采取微型种植钉支抗治疗,观察并分析两组口腔正畸患者的临床效果和不良状况。结果经治疗,实验组患者的磨牙位移为(0.74±0.68)mm,小于对照组(3.72±0.63)mm,另外,实验组的上中切牙倾角减小量为(29.67±6.89)°,凸距减小量为(4.62±0.87)°,均高于对照组,实验组无种植体松动现象,而对照组有2例种植体松动现象,两组数据差异有统计学意义(P<0.05)。结论在口腔正畸中采用微型种植钉支抗具有很好的临床效果,矫正效果明显,安全性高,无明显的不良反应。

Objective To study and analyze the clinical effect of mini-implant anchorage in orthodontics.Methods 80 cases of patients with orthodontics in our hospital from January 2010 to January 2017 were randomly selected and randomly divided into two groups,the control group were treated with facebow anchorage,while the experimental group were treated with mini-implant anchorage,and the clinical effect and adverse state were compared and analyzed.Results After treatment,the molar displacement in the experimental group was less than that in the control group,[(0.74±0.68)mm vs(3.72±0.63)mm],besides,the decrease of obliquity of upper and medial incisors and convex distance in the experimental group were respectively(29.67±6.89)°and(4.62±0.87)°,which were higher than those in the control group,and no case had implant loose in the experimental group and 2 cases had implant loose in the control group,and the differences between groups were statistically significant(P<0.05).Conclusion The clinical effect of mini-implant anchorage in orthodontics is good with obvious correction effect and high safety,but without obvious adverse reactions.
