采用单次滑动法研究了全瓷义齿的表面磨损和摩擦性能。研究了环境、表面类型（牙釉质或牙本质）和重复次数对牙齿磨损特性的影响。牙齿的釉质表面比牙本质表面更能抵抗渗透和表面损伤。双道次滑动损伤比单道次滑动损伤严重。水和人唾液的液体环境对磨损特性的影响相似。定量差异的磨损参数调查发现两个品牌的瓷义齿之间。
Surface wear and frictional behavior of porcelain denture teeth were examined with a single-pass sliding technique. The influence of environment, type of surface (enamel or dentin) and repeated passes on the wear characteristics of the teeth were investigated. The enamel surface of the teeth was more resistant to penetration and to surface damage than the dentin surface was. Damage was more severe for double-pass than for single-pass sliding. The wear characteristics were affected similarly by the liquid environments of water and of human saliva. Quantitative differences in the wear parameters investigated were found between the two brands of porcelain denture teeth.
