Abstract
Purpose: The purpose of this study was to investigate the effect of addition of fiber glass on the physical properties of silanized fiber mesh and non silanized mesh of denture base resins.
Methods:The denture base resins were used in this study heat curing acrylic resins(Vertex Rs, Lucitone 199, 20 80 ) and fiber glass(SES, Green B&D co., Ltd, 20 80 ) were used as reinforcement. The specimens were stored in distilled water at 37 2 for 72 hours before test. Bending strength and tensile strength were measured by an universal testing machine(Instron 4301, Instron Corp.). Penetration distribution on fiber was observed by scanning electron microscopy(JSM 840A, Jeol Ltd).
Results: The bending strength and modulus were increased by 30% after adding fiber glass on denture base resins. Tensile strength showed significant increasing by adding fiber glass on denture base resins.
Conclusion: In this study, Addition of silanized fiber in denture base resins were improved physical properties. we confirmed the fiber glass possibility of the replacement about conventional materials.
