Studies on mechanical properties of denture base material laminated with organic fiber reinforced plastics. Part I.
Abstract:
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.
