摘　　要：目的 :揭示各类错发病率及其与偏颌畸形发病率的关系。方法 :以个别正常为标准 ,按安氏分类法 ,检查各类错及偏颌畸形的发病率 ,数据经SPSS统计软件分析处理。结果 :1 错发病率为 77 4% ,其中Ⅰ类错 5 5 4% ,Ⅱ类错 13 4% ,Ⅲ类错 8 6 %。 2 偏颌畸形的发病率在Ⅲ类错中最高 ,Ⅰ类错最少。 3 偏颌畸形在错中的发病率显著高于正常咬合者 ,下颌左偏者大于右偏者。结论 :安氏Ⅲ类错中偏颌畸形的发病率较高 ,Ⅱ类次之 ,Ⅰ类最少。Objective:To investigate the frequency of malocclusion and reveal the correlation of malocclusions and mandibular deviations.Methods:The criteria were individual normal occluision and Angles classification.All data were analyzed by SPSS statistical software.Results:①The prevalence of malocclusions was 77.4%(Class Ⅰ is 55.4%,Class Ⅱ is 13.4%,and Class Ⅲ is 8.6%).②The frequency of mandibular deviation was highest in Class Ⅲ and lowest in Class Ⅰ.③The prevalence of mandibular deviation in malocclusions was significantly higher than in normal occlusions.In the individuals with mandibular deviation,the lower jaws were more frequently shifting to the left side than to the right side.Conclusion:Mandibular deviations are more often demonstrating in Class Ⅲ.
