Improving the mechanical properties of fiber-reinforced acrylic denture-base resin

This study evaluated the effects of different oligomers and silane-treated filler on the bending strength, bending modulus, compressive strength and compressive modulus of a fiber-reinforced acrylic resin for use in denture bases. The results showed that the investigated oligomers only improved the bending modulus. Using an inorganic filler treated with two types of silanes – γ-methacryloxypropyltrimethoxy silane and triethoxyvinyl silane – considerably improved the mechanical properties of the fiber-reinforced acrylic resin except for the bending strength, with triethoxyvinyl silane being more effective than γ-methacryloxypropyltrimethoxy silane. The improvement of the mechanical properties of fiber-reinforced acrylic resin is the incorporation of triethoxyvinyl silane-treated filler.
