摘　　要：目的观察前方牵引器治疗骨性前牙反合的效果。方法选取我院2010年8月-2016年8月收治的45例骨性Ⅲ类前牙反合患者资料作为研究对象,其中男22例,女23例,年龄6-11岁,平均(9.23±2.31)岁,本组患者均行前方牵引器进行治疗,观察并对比治疗前后本组头颅定位侧位片测量结果。结果:本组SNA、SNB、NL-SBL、ML-SBL角及B-Ver T、Id-Ver T治疗前后对比均未显示高度差异(P>0.05);但治疗后ANB、NL-ML角及、Co-A、Pr-Ver T、Co-Goi、A-Ver T、CoGn、Goi-Gn均较治疗前显著提高(P<0.05)。结论骨性前牙反合行前方牵引治疗较明显改善患者的侧貌,并有效促进上颌骨的生长且促进下颌轻度向下向后旋转,进而显著提高矫治效果。Objective To observe the effect of the forward traction device in the treatment of bone anterior teeth. Methods The data of 45 patients with skeletal type Ⅲ anterior teeth were selected from August 2010 to August 2016. Among them,22 males and 23 females,aged 6-11 years,mean（9.23 ± 2.31） years old,this group of patients were treated in front of the traction,observation and comparison before and after treatment of this group of skull positioning lateral radiographs. Results： There were no significant differences in SNA,SNB,NL-SBL,ML-SBL and B-Ver T and Id-Ver T before and after treatment（P〉0.05）. However,after treatment,ANB,NL-ML and Co-A,Pr-Ver T,Co-Goi,A-Ver T,Co-Gn and Goi-Gn were significantly higher than those before treatment（P〈0.05）. Conclusion The anteroposterior traction of the anterior crossbite is more effective in improving the appearance of the patients,and effectively promoting the growth of the maxilla and promoting the downward rotation of the mandibular mild downward,and thus significantly improve the treatment effect.
