摘要/Abstract

摘要：

目的比较不同面部生长型正常的前牙倾斜度，以及安氏Ⅱ类1分类错的前牙代偿特征，为临床治疗提供参考。方法在X线头颅定位侧位片上对158例正常及246例安氏Ⅱ类1分类错的前牙倾斜度相关的测量指标进行分析，并研究其代偿特征。结果1）正常垂直生长型中上下颌前牙相对舌倾，水平生长型中上下颌前牙相对唇倾。2）与正常不同生长型均值比较，安氏Ⅱ类1分类错上颌前牙在不同生长型中相对于正常均唇倾，下颌前牙在垂直生长型和平均生长型中相对于正常唇倾，在水平生长型中没有变化。结论在临床矫治安氏Ⅱ类1分类错患者时，应根据患者的生长型及牙代偿特征，选择相应的矫治方法和控制重点。

Abstract:

Objective To investigate characteristics of incisors inclination and dental compensation in normal occlusion and Angle’s Class Ⅱ division 1 malocclusion with different growth patterns. Methods 158 cephalometric films of normal occlusion and 246 cephalometric films of Angle’s Class Ⅱ division 1 malocclusion were selected and the data of relevant variables were compiled to analyze the inclination of incisors. Results The upper and lower incisors were lingually inclined in normal occlusion with vertical growth pattern while labially inclined in horizontal growth pattern. Compared with the average value of normal occlusion with different growth patterns, the upper incisors of Class Ⅱ division 1 malocclusion were relatively labially inclined in different growth patterns and the lower incisors were labially inclined in vertical and average growth patterns, while there were no obvious changes in horizontal growth pattern. Conclusion When treating patients with Angle’s Class Ⅱ division 1 malocclusion, we should choose a specific method according to patients’growth patterns and characteristics of dental compensation.
