目的：探讨山东地区青少年 AngleⅡ1错牙合患者的错牙合机制、颅面形态特征及发育规律。方法：随机抽取在潍坊牙科医院就诊的青少年 AngleⅡ1错牙合患者82例为研究对象，对每位患者拍摄头颅定位侧位 X 线片，使用 Steiner 分析法对颅面部的相关点、线、角进行测量，并将所得的各项测量数据与正常值进行比较。结果：山东地区青少年AngleⅡ1错牙合患者 SNB、ANB、SND、1-NA（mm）、1-NA、1-1（-）、GoGn -SN、SL（mm）的8项测量值与正常值比较差异有统计学意义（P ＜0．05）。结论：山东地区青少年 An-gleⅡ1错牙合患者上颌基本正常，下颌相对上颌明显后缩，上切牙明显唇倾。

Objective To analyze hard tissues of young adults with Angle’s class Ⅱ division 1 malocclusion by cephalometrics,and separately to investigate in contrast with the standard of normal occlusion in the native area.Methods Selected 82 patients suf ering form young adults with Angle’s class Ⅱ division 1 malocclusion who visited in the stomatological Hospital of Weifang. For each subject,cephalo -metrics radiographs were taken before treatment.The lateral cephalograms of each one were taken and measured by the same orthodontics doctors based on applica-tion of Steiner methods.Results There were dif erence in measurements of SNB、ANB、SND、1 -NA(mm)、1 -NA、1 -1(-)、GoGn -SN、SL(mm)between young adults with Angle’s class Ⅱdivision 1 malocclusion in Shandong Province and normal people(P <0.05).Conclusion The maxil y of young adults with Angle’s class Ⅱ division 1 malocclusion in Shandong Province is nor-mal,and the mandibular is retruded,which makes a distal malocclusion.
