摘　　要：目的探讨矫治对咀嚼效率的影响。方法采用重量法测出包括上颌前突,前牙反,拥挤在内的26例错矫治前及矫治结束时的咀嚼效能。其中上颌前突8例,前牙反7例,拥挤11例。采用SPSS10.0统计软件中配对t检验程序对错矫治前后错咀嚼效率值进行配对t检验。结果上颌前突矫治前后咀嚼效率的配对t检验P=0.006,有高度显著性差别。前牙反矫治前后咀嚼效率的配对t检验P=0.200,有显著性差别。拥挤矫治前后咀嚼效率的配对t检验P=0.513,无显著性差别。结论咀嚼功能及咀嚼效率不仅受牙齿排列、关系的影响,很重要的还要受牙齿稳固程度的影响。Objective To investigate the effect of masticatory efficicency before and after orthodontic. Methods Weight method was used to measured masticatory efficicency in 26 patients with difference malocclusion （8 cases with maxillary protrusion, 7 cases with anterior crossbite and 11 cases with crowding） bdfore and after orthodontic. The differences were analyed with paired T test. Results The masticatory efficicency had high statistically significant difference in patients with maxillary protrusion between pretreatment and posttreatment in maxillary protrusion （ P = 0.006）, The masticatory efficicency had statistically significant difference in patients with anterior crossbite between pretreatment and posttreatment （ P = 0. 200）. The masticatory efficicency had not statistically significant difference in patients with crowding between pretreatment and posttreatment （ P = 0.513）. Conclusion The masticatory function and efficiency was effected not only by teeth arrangement and relatiolmhip of occlusion but also by the degree of teeth stability that is very important.
