An in vitro study was conducted to evaluate the abrasive wear resistance of high-strength denture teeth (HS teeth). Eight types of specimen were used in the experiments; 3 types of HS teeth, 3 types of conventional plastic denture teeth (PL teeth), porcelain teeth and metal teeth. Sliding-induced wear tests were conducted by sliding the samples on a metal plate. The abrasive wear resistance of the samples was evaluated in terms of wear depth, weight loss and SEM observation. Comparison of wear depth showed that abrasive wear resistance of HS teeth was 4.7 times that of PL teeth, 0.7 times that of porcelain teeth and 8.3 times that of metal teeth. In terms of weight loss, the corresponding values were 3.3-fold, 0.2-fold and 11.4-fold, respectively.
进行了一项体外研究，以评估高强度义齿牙齿（HS牙齿）的耐磨耗性。实验中使用了8种类型的样本；3种类型的HS牙齿、3种类型的传统塑料义齿牙齿（PL牙齿）、瓷牙和金属牙。通过在金属板上滑动样本进行滑动诱导磨损试验。根据磨损深度、重量损失和扫描电子显微镜观察来评估样本的耐磨耗性。磨损深度的比较表明，HS牙齿的耐磨耗性是PL牙齿的4.7倍、瓷牙的0.7倍和金属牙的8.3倍。就重量损失而言，相应的值分别为3.3倍、0.2倍和11.4倍。
