通过100颗人尸颌骨上牙齿拔除的过程,测得牙脱位的外拉力及拉力与牙位移的关系,同时仿临床拔牙术,应用水平作用力使牙齿摆动,颌骨产生可塑性变型后,造成牙脱位的外力关系。本文提出了不同类别的牙齿,其单纯脱位与水平摆动后脱位外拉力的降低百分比。同时就脱位运动的牙长轴圆心作用点进行了讨论。对牙脱化实验装置进行了研究,初步进行设计,为进一步进行相类似的研究提出了建议。
Through the process of tooth extraction on 100 human corpse, the relationship between external force and pulling force of tooth dislocation and the displacement of tooth was measured. At the same time, it imitated the clinical extraction of tooth, the horizontal force was applied to swing the tooth and the plastic deformation of the mandible resulted External relations of tooth dislocation. This paper presents the different types of teeth, the simple dislocation and horizontal swing after the dislocation of the reduction in the percentage of external tension. At the same time, the central axis of the long axis of dislocation movement was discussed. The experimental equipment of tooth decalcification was studied, and the preliminary design was carried out. Some suggestions for further researches were put forward.
