Acrylic resin is widely used as a denture base material, but the upper complete denture fails often during use. Therefore, the denture base made from acrylic resin should be reinforced in some way. Therefore, as a new method of reinforcement on the denture base, the authors devised a method to improve the strength and rigidity by laminating the palatal surface of the denture base with an organic fiber reinforced plastic, the so-called canapé construction. In this paper, as the basic experiment, the flexural strength, fatigue strength and the modulus of elasticity in bending of reinforced acrylic resin by the canapé construction were investigated. As the results, the flexural and fatigue strength are improved respectively 160% and 130% compared to the denture base acrylic resin. And the modulus of elasticity in bending is improved 80%. Therefore, it is considered that this new combination of materials using the canapé construction might be sufficiently applied to the denture base.
丙烯酸树脂作为义齿基托材料被广泛使用，但上颌全口义齿在使用过程中经常失败。因此，由丙烯酸树脂制成的义齿基托应以某种方式进行加固。因此，作为义齿基托加固的一种新方法，作者设计了一种通过在义齿基托的腭面用有机纤维增强塑料进行层压来提高强度和刚度的方法，即所谓的覆盖义齿结构。在本文中，作为基础实验，研究了采用覆盖义齿结构的增强丙烯酸树脂的弯曲强度、疲劳强度和弯曲弹性模量。结果表明，与义齿基托丙烯酸树脂相比，弯曲强度和疲劳强度分别提高了160%和130%。弯曲弹性模量提高了80%。因此，认为这种采用覆盖义齿结构的新材料组合可能足以应用于义齿基托。
