Abstract
The experimental fiber-reinforced resin splint materials were prepared, and their mechanical properties (transverse strength and elastic modulus) were investigated. These resin splints were based on urethane dimethacrylate-based monomer, silica filler, and polymethylmethacryalte polymer beads. To improve the mechanical properties of the resin splints, glass cloth and glass fiber were incorporated into the splints. The results of this study revealed that the incorporation of glass fiber was effective in improving the mechanical properties. The mechanical properties of glass fiber-filled splints were significantly improved by increasing the ratio of glass fiber. The glass cloth-filled splints showed lower mechanical properties than the glass fiber-filled splints. The mechanical properties of the glass fiberfilled splints were not affected by immersion in water. These results suggested that glass fiber reinforcement would be an effective method for improvement of the mechanical properties of the experimental resin splint materials.
