【摘要】Objective To evaluate the differences of Bolton’s anterior and overall ratios in Angle classⅢ malocclusion patients with different facial vertical skeletal patterns.Methods 150 skeletal classⅢ subjects were involved in this study. According to skeletal vertical type, the samples were assigned to 3 groups: average facial type, long facial type, short facial type. Each group consisted of 50 subjects. The mesio-distal width from left ifrst molar to right ifrst molar was measured.Bolton anterior and overall ratios were calculated, t test and ANOVA were performed for statistical analysis with SPSS17.0 software package. Results No statistically signiifcant sex difference was found in anterior or overall ratio in any group. No signiifcant difference in all ratios between average facial type and long facial type were noted. Signiifcant difference was found for all ratios between short facial type and average facial type, so with long facial type.Conclusion The mean anterior and overall ratios for short facial type are greater than those for average and long facial types.%目的：分析Bolton指数在安氏Ⅲ类错牙合不同垂直骨面型中的差异，为正畸诊断治疗提供依据。

方法：选择符合标准的150副骨性安氏Ⅲ类错牙合模型，按不同垂直骨型分为均角、高角、低角三组，每组各50副。

分别测量两侧第一恒磨牙间每颗牙的近
远中宽度，计算各组前牙比和全牙比。

采用SPSS17.0软件包对数据进行配对t检验和方差分析。

结果：各组男女前牙、全牙比无显著差异，均角组和高角组的前牙比和全牙比无显著差异，低角组的前牙比和全牙比与均角组和高角组有显著差异。

结论：低角型安氏Ⅲ类错牙合的前牙、全牙Bolton比较均角型和高角型大。
