During open/close movement, the distance of condylar movement is smaller than normal occlusion(P.05). During protrusion/retrusion movement, protrusion extent increase,the distance of condylar movement is bigger than normal occlusion(P.05). During lateral excursion, the trace in sagittal plane of the non-working side condyle is more incline than protrusion movement trace and the distance of the left non-working side condylar movement is larger than the right. During mediotrusion/right movement, the left biggest space distance is larger than normal occlusion and the transversal condylar inclination is smallar than normal occlusion when the distance of condylar movement is 5mm, the difference is statistically significant.

在开闭口运动时，双侧髁突运动幅度减小、位移量小于正常牙合者(P.05)；前伸后退运动时，前伸幅度增加，位移量大于正常牙合者(P.05)；侧方运动时，非工作侧髁突在矢状面上的轨迹较前伸轨迹向前下方倾斜度增加，非工作侧髁突空间位移左侧大于右侧，向右侧方运动中，左侧髁突空间位移大于正常牙合者，髁突位移5mm时水平面髁突倾斜度小于正常牙合者，差异有统计学意义。

According to experts' advice, more than 90% of adults suffer from periodontal disease of different degrees, especially those often smoking tobacco and drinking coffee, they have dental plaques on their teeth, and their gums are apt to bleed; people with a peculiar smell in their mouth cavity had better do toothwash regularly; everyone should develop a habit of toothwash once every half year or once every year according to their different conditions of the teeth; in the week after the toothwash, they are advised to avoid eating too cold or too hot food.

Place short and long food chips in posterior occlusion of unilateral left side. When the masticated load was 3、5、7 kg, the displacement of abutments was measured by a LB-high sensitive laser transferring detector to calculate displacement, inclination and torsion of the abutment in mesial-distal, labial lingual and vertical and horizontal directions.

分别在左侧后牙区放置长、短食物片的咬合状态下，负载3 kg、5 kg、7 kg咬合力时，用高精度半导体激光位移测量仪测量并计算出同侧基牙在近远中向、颊舌向的水平位移和倾斜、垂直向的位移和水平旋转，统计分析不同牙尖斜度对基牙位移的影响。
