摘　　要：目的:采用Enlow分析法评价肌激动器对安氏Ⅱ类1分类错牙合畸形矫治前后骨面型的变化,探讨肌激动器矫治安氏Ⅱ类1分类错牙合的机理。方法:选取在哈尔滨医科大学附属口腔医院就诊的安氏Ⅱ类1分类错牙合畸形患者35例(男16例,女19例),年龄10-12岁。由作者测量其SNA角、SNB角、ANB角、Y轴角、U1/PP角、L1/MP角、A-Ptm值、B1值、J-B值、LI-MP值、U1-PP值、Go-Cd值、A1值及A2值。每项指标测量3次取平均值,对测量结果采用配对t检验,对矫治前后的测量结果进行分析。结果:(1)矢状向上,SNA,U1/PP,A-Ptm矫治后均变小,差异有统计学意义(P<0.05),B1矫治后增大,但是与矫治前相比,差异无统计学意义(P>0.05),SNB、ANB、L1/MP、J-B均增大,差异有统计学意义(P<0.05),Y轴角矫治后增大,但是与矫治前相比,差异无统计学意义(P>0.05);(2)垂直方向上,U1-PP、L1-MP、Go-Cd、A1、A2均增大,差异有统计学意义(P<0.05)。结论:肌激动器可以改善安氏Ⅱ类1分类错牙合上下颌骨的矢状向以及垂直向的相互关系,从而有效改善患者面型。Objective Using the Enlow,s counterpart analysis to evaluate the changes before and after activator treatment of craniofacial deformity occurred on class II Division1malocclusion,and to analyse the mechanism of activator treatment of class II Division1malocclusion.Methods35patients with classⅡDivision1malocclusion deformity who were visited in the clinic of Stomatology hospital of Harbin Medical University were selected(male16cases,female19cases),aged10-12years old.The author measures its SNA angles,SNB angles,ANB angles,Y axis angles,U1/PP angles,L1/MP angles,A-Ptm values,B1values,J-B values,LI-MP values,U1-PP values,Go-Cd values,A1values,and A2values.Each index was measured3times and the average values were taked.The paired t test was used to analyze the measurement results before and after orthodontic treatment.Results①The sagittal direction,SNA,U1/PP,A-Ptm after treatment were reduced,the difference was statistically significant(P<0.05).B1after treatment increased,but compared with before treatment,the difference was not statistically significant(P>0.05).SNB,ANB,L1/MP,J-B are increased,the difference wasstatisticallysignificant(P<0.05),Y angle increased.But after treatment compared with before treatment,the difference was not statistically significant(P>0.05).②In vertical direction,U1-PP,L1-MP,Go-Cd,A1,A2increased,the difference was statistically significant(P<0.05).Conclusion Activator can improve class II Division1malocclusion,relationship between the upper and lower mandible,so as to effectively improve the patient's face.
