The purpose of this study was to evaluate the titanium castability with a spin typecasting machine(TiCast, Super R, Selec, Osaka. Japan). We tested phosphate bondedinvestment “Rematitan�Plus(Dentaurum, Inc., Pforzheim, Germany)”of mesh grid patternand plate pattern. Four different mold temperatures(room temperature, 200℃, 400℃and600℃) were prepared for the present study. In mesh grid pattern with spruing of φ0.88㎜dimeter, when the mold temperature increased, high percentage of castability was gained.Mold temperature showed a highly significant(p<0.05) correlation on the castability, Inplate pattern, the higher the mold temperature during casting, the greater the adhesivephenomenon between Ti surface and the investment.
