[摘要]目的：研究乌鲁木齐市维吾尔族青少年安氏Ⅱ1类错牙合的骨型和牙性矢状向特征，比较乌鲁木齐市维吾尔族青少年与汉族青少年安氏Ⅱ1类错牙合的差异性。方法：通过测量100例维吾尔族青少年与100例汉族青少年安氏Ⅱ1类错牙合的头颅侧位片，应用NEMO CEPH NX头影测量系统统计分析各项测量的均值和标准差，分别比较维吾尔族安氏Ⅱ1类错牙合与汉族安氏Ⅱ1类错牙合的骨型和牙性矢状向特征的差异性。结果：①维吾尔族和汉族青少年安氏Ⅱ1类错牙合在构成类型上都以上颌骨正常，下颌骨后缩最多见，这种类型在维吾尔族占71%，在汉族64%。②维吾尔族和汉族青少年安氏Ⅱ1类错牙合在上颌骨正常，下颌骨后缩的类型中的比较， U1/NA、U1/L1、L1/NB、U1-NA、L1-NB、Po-NB这6项测量值和汉族青少年有显著统计学差异，其它测量值无统计学差异。结论：维吾尔族和汉族青少年安氏Ⅱ1类错牙合比较分析，维吾尔族上前牙较汉族唇倾，且下前牙较舌倾，颏部发育较好。

Abstract： Objective To investigate in ClassⅡ1 malocclusion for the Uygur adolescents and Hans adolescents， contrast the difference of Uygur adolescents and Hans adolescents in ClassⅡ1 malocclusion. Methods 100 Uygur adolescents and 100 Hans adolescents with classⅡ1 occlusion were selected. The lateral cephalograms of each one were taken and measured by NEMO CEPH NX cephalometric measurement software （provided by Bei Jing medical university）， all of the data were statistically analyzed with statistic methods， contrast the difference of Uygur adolescents and Hans adolescents in ClassⅡ1 malocclusion. Results Study indicates that there are significant differences on U1/NA， U1/L1，L1/NB，L1-NB，U1-NA，Po-NB（P<0.01）. Conclusion The Uygur adolescents have normal maxilla and retrusive mandibular， also possessed more protrusive upper incisors，possessed mental development.The Hans adolescents have protrusive maxilla and retrusive mandibular and mental dificency.

新疆维吾尔族患者占门诊就诊患者的10%左右，维吾尔族患者颅颌面特征与汉族有很大的差异。目前，国内文献关于维吾尔族青少年安氏Ⅱ1类错牙合颅面特征方面的报道较少，资料大多来自汉族。

不同地区和种族的人群具有特定的颅颌面特征，其错牙合畸形的特征也存在差异。维吾尔族青少年安氏Ⅱ1与汉族青少年安氏Ⅱ1类错牙合存在很大的差异。……
