| Abstract |
An implant material for living body was developed using oxide stabilized zirconia, and as a result of studying process control, aesthetics, and mechanical characteristics, the following conclusions were obtained. Stabilized zirconia with 5% addition of Y2O3 was used as ZrO2 used in the study, 10% of PVA was added as a binder after 40 hours of First Ball Milling, and after adding a lubricant in consideration of the lubrication of the material, Second Ball Milling was performed for 4 hours. As a result of the light transmittance, 23 to 28%, and as a result of measuring hardness and destructive toughness, satisfactory results of 1240 to 1270HV and 6 to 8MPa·m1/2 were obtained, respectively. For production block production, 1 to 6% of oleic acid and diesel, which are secondary lubricants, were added to granule powder at a 1:1 ratio to obtain excellent moldability and physical properties from specimen samples added at 4% |
