The acrylic resin denture base is used more than the metal denture base, but especially upper complete denture base, it has the following week points : The patients feel the sense of incompatibility due to a thick palatal area of denture base, and the acrylic resin denture base fails in a few years because the acrylic resin has low fatigue strength.Methods to thin the palatal area of acrylic resin denture base by reinforcement such as Carbon Fiber (CF) and Aramid Fiber (AF) cloths were developed and the static and fatigue properties of the reinforced denturc bases were examined.The palatal area of CF and AF-cloth reinforced denture bases became 50% and 40% thinner, respectively.In static property, the stiffness and strength of both reinforced denture bases somewhat improved compared to those of acrylic resin denture base alone.In fatigue property, the CF and AF-cloth reinforced denture bases were, respectively, 1.86 and 1.76 times stronger at N=10^5 cycles.

丙烯酸树脂义齿基托比金属义齿基托使用得多，但尤其是上颌全口义齿基托，它有以下几个星期的要点：患者因基托腭部较厚而有不相容感，本文介绍了采用树脂基托加固的方法，对树脂基托的腭部进行减薄，本文研究了碳纤维布和芳纶纤维布增强基托的静态和疲劳性能。碳纤维布和芳纶纤维布增强基托的腭部厚度分别比纯丙烯酸树脂基托薄50%和40%。在静态性能方面，两种纤维布增强基托的刚度和强度均有所提高。在疲劳性能方面，在N=10^5次循环时，CF和AF布增强的义齿基托的强度分别为1.86和1.76倍。
