The potential correlation of the force versus time behavior of four resilient lining materials and their acceptance by patients was investigated. Two modified acrylic resins and two silicone denture lining materials were tested. The response of the soft lining materials to a programmed indentation test was used to define a parameter for each denture liner product. A parameter defined as the "Rebound Index," using force-time data obtained from the indentation measurements, was significantly different for the modified acrylic resins compared to the silicone materials. Improved patient acceptance was correlated with higher values of this index.
研究了四种弹性衬里材料的力随时间变化行为与其被患者接受程度之间的潜在相关性。测试了两种改性丙烯酸树脂和两种硅树脂义齿衬里材料。通过软衬里材料对程序控制压痕试验的响应来为每种义齿衬里产品定义一个参数。利用从压痕测量中获得的力-时间数据定义的一个参数“回弹指数”，改性丙烯酸树脂与硅树脂材料相比有显著差异。患者接受度的提高与该指数的较高值相关。
