目的 Coben法分析女性恒牙初期安氏Ⅱ2类错畸形患者的颅颌特征,比较安氏Ⅱ2和Ⅱ1类女性患者及正常值间差异。方法 24名女性恒牙初期安氏Ⅱ2类错畸形患者,用Coben法分析其X线头颅侧位定位片,所得结果与安氏Ⅱ1类女性患者及哈尔滨地区正常女性间进行比较。结果恒牙初期女性安氏Ⅱ类错畸形2分类和1分类间的Coben分析法中很多测量项目间差异有统计学意义,且大部分测量结果明显偏离正常值。结论 Coben分析法反映了女性恒牙初期安氏Ⅱ2错畸形患者的颅颌特征。
Objective Coben method was used to analyze the craniofacial features of patients with Class Ⅱ division malocclusion in the early stage of female permanent dentition. The differences between normal women in Class Ⅱ2 and Ⅱ1 women were compared. Methods Twenty - four female patients with Class Ⅱ division malocclusion in the early stage of permanent dentition were analyzed by Coben ’s method. The results were compared with those in class Ⅱ 1 female and normal female in Harbin. Results In the early stage of permanent dentition, there were significant differences between the two items in Coben analysis method for Class Ⅱ malformations of Class Ⅱ malformations and most of the measurement items deviated from the normal values. Conclusion The Coben analysis reflects the craniofacial characteristics of patients with Angle Ⅱ 2 malformations in the early stage of female permanent dentition.
