项目摘要
To clarify the relation between the supporting load of the abutment teeth and the mobility of the removable partial denture,four studies were investigated on the relation between the denture stability and planning factors including occlusal factors, on the relation between the supporting load of periodontal tissues and aging of occlusal form, on the control ability of jaw position connecting with control system of the mastication and on the longitudinal change of periodontal tissues and residual ridge after denture insertion.1.The lateral displacement of the tissue-born denture showed 200-350um in the lateral gliding movement, and showed 350-500um in the lateral gliding movement interposing a rubber seat interocclsally.2.In the fact that the supporting load of the teeth is proportinal to the closely occlusal area, the supporting load increases with the development of attrition, however, the growthing ratio of supporting load may hardly change between the kind of tooth.3.When the lateral inclination of occlusal facet changed, the path way of final phase of chewing stroke adapted soon in the several strokes just after its change. And when the maximally intercuspidated position made about one mm far from correct position, the path way of final phase of chewing stroke changed after insertion of the denture, however, the differences of the path way remarkably decreased at seven days after insertion of it.4.The condition of gingivae of the abutment is good in buccal side, and worse in lingual and proximal side.
为阐明基牙的支持力与可摘局部义齿活动度的关系,对义齿稳定性与包括咬合因素在内的设计因素的关系、牙周组织的支持力与咬合形态老化的关系、结果:1.牙槽嵴的横向位移与牙槽嵴的纵向位移呈负相关,牙槽嵴的纵向位移与牙槽嵴的纵向位移呈负相关; 2.牙体的支持力与近牙合区成正比,随着磨耗的发展,支持力逐渐增大,但随着磨耗的增加,牙体的支持力逐渐增大,牙体的支持力逐渐减小,牙体的支持力逐渐增大,牙体的支持力逐渐减小,牙体的支持3.当牙合小平面侧向倾斜度发生变化时,咀嚼行程最后阶段的路径在其变化后的几个行程中很快就适应了。当牙尖最大接触位置偏离正确位置约1 mm时,义齿戴入后咀嚼行程最后阶段的路径发生改变,但在戴入后第7天,路径差异显著减小。4.基牙颊侧牙龈状况较好,舌侧和基牙近侧较差。
