There is considerable debate as to the effects of using bridges which are supported simultaneously by teeth and implants, due to the marked differences in their displaceability. This in-vivo experiment was carried out on three subjects, and measured the vertical and horizontal movement of implants and teeth, linked with a fixed superstructure, when this was loaded. The results suggest that natural abutment teeth may contribute significantly to bridge support in these circumstances.
关于使用同时由牙齿和种植体支撑的桥体的效果存在相当大的争议，因为它们的可位移性存在显著差异。这项体内实验在三名受试者身上进行，测量了与固定上部结构相连的种植体和牙齿在加载时的垂直和水平移动。结果表明，在这些情况下，天然基牙可能对桥体支撑有显著贡献。
