Abstract
This study investigated the effects of surface treatment for filling resins on the surface texture of denture resin teeth by the use of scanning electron microscope. This study also evaluated the bond strength of filling resins to denture resin teeth. The denture resin teeth in this study was Endura Posterio(Shofu Co., Japan). The filling resins used were Coe-cure(Coe Co., USA), Vertex RS (Dentimax Ziest, Holland), and light cured resin Z-100(3M Co., USA). The test sample were divided into 3 parts. Group 1 : Sandblasted with 50micrometer Aluminum oxide. Group 2 : Treated with #60 silicone carbide paper. Group 3 : Treated with monomer brush application. Control Group : No Treatment. The results were as follows; 1.The bond strength of filling resins to denture resin teeth is increased by surface treatment. 2.Regardless of the filling resins, there was a significant difference with # 60silicone carbide paper treated group. 3.Regardless of each group, the bond strength according to the filling resins were decreased in the following order: Vertex RS, Coe-cure and Z-100.
