This study examined the application of rubber metal to removable partial denture clasps. \n[Material and Method] Seven clasp arms (hereinafter referred to as “cast-GM”) made of cast rubber metal were fabricated as specimens for the constant displacement fatigue test. For the constant displacement fatigue test and the comparison of permanent deformation, rubber metal (hereinafter GM) were fabricated using a cold working press. 12% gold-palladium-silver alloy (hereinafter 12%Pd), and cobalt-chromium alloy (hereinafter Co-Cr) as comparison material were made by casting. In the constant displacement fatigue test, the length from the base of the hook arm to the tip of the hook was set to 12 mm, and a constant displacement (0.5 mm) corresponding to the amount of undercut was applied at a point 2 mm from the apex of the clasp arm. Repeated constant displacement was applied up to 25,000 times at a rate of 100 cycles / min. The surface of the clasp arm specimens was observed for cracks every 500 cycles for the cast-GM test, every 5,000 cycles up to 20,000 cycles for the comparison test of GM, 12%Pd and Co-Cr, and every 1,000 cycles after 20,000 cycles using an optical microscope. To measure the amount of permanent deformation, a universal tester was used to apply a constant displacement (0.25 mm) to the part 2 mm from the hook apex. The constant displacement was applied at 10 mm/min for up to 300 repetitions, and the distance after 300 repetitions was measured as the amount of permanent deformation. The mean values of the permanent deformation of each group were examined by one-way ANOVA, and the Dunnett test with a significance level of 5%. \n[Result] In the constant displacement fatigue test, cracks and fractures were found in 2 out of 7 cast-GM samples, and these cracks and fractures were found along the bubbles on the sample surface. After repeated loading of 25,000 times, cracks were found in samples of both 12%Pd and Co-Cr, apart from indentations due to fixation and loading, but cracks and fractures were not observed in GM. The mean value of the amount of permanent deformation under a 300-time repeated load was significantly smaller in GM than 12%Pd and Co-Cr.
