| 摘 要： | 目的 分析楔状缺损与He的关系。方法 选择125例患楔状缺损的中老年人，按楔状缺损的严重程度分为正常、轻、中、重四组。采用临床咬合诊断方法进行安氏咬合分类、颞下颌关节功能、He的分类、He功能情况的检查。结果 楔状缺损患者的安氏错He及偏侧咀嚼人数比例明显高于未患牙；楔状缺损的工作侧He干扰人数多于正常人，患牙的工作侧He干扰牙数也高于未患牙。结论 楔状缺损的发生与He力负担过重及异常He力有关。

| Abstract: | Objective To clinically investigate and identify the occlusal conditions as one of the factors related to formation of wedge-shaped defects.Methods Subjects of 125 were selected from a group of middle-aged and elderly people in an urban area.According to the depth of wedge-shaped defects,subjects were divided into four groups:control,light,middle and severe group.Angle's classification function of temporomandibular joint,occlusal pattern and occlusal function were examined by clinical diagnosis technique.Results The angle's malocclusion and unilateral mastication could be related to the formation of wedge-shaped defects.Significant relationship was found between the laterotrusive working interference and the formation of wedge-shaped defects.Conclusion Overload and dysfunction occlusal force could have relation to the progression of wedge-shaped defects. |
