Wear characteristics of hybrid denture teeth, plastic denture teeth which were partially reinforced with metal, was evaluated. The plane specimens were made up with resin and metal. Light curing veneering resin, New metacolor, heat curing veneering resin, Mitel-OM and PMMA (Poly methyl methacrylate) were used for resin parts, while gallium containing filling alloy, silver alloy, palladium alloy and titanium containing chromium cobalt alloy were used for metal parts. The stecimens were abraded by the rod stecimens of palladium alloy with abrasion test machine. The wear depth and width were measured at 1, 5, 10 and 20×10^4 times of abrasion which stroke was 10 mm each. The srecimens of heat cured veneering resin reinforced with chromium cobalt alloy showed the least wear loss while the specimens of PMMA reinforced with silver alloy did the most. The difference of wear ratio between light cured and heat cured veneering resin was not statistically significant.
