Method for manufacturing zirconia slurry for forming porous surface on abutment and crown of ceramic implant and method for manufacturing implant using the same

Abstract

The present invention relates to a method for manufacturing a zirconia slurry for forming porous surfaces on an abutment and a crown of a ceramic implant, the method including: the zirconia pulverization step (step S10) of putting zirconia powder, carbon powder as a foaming agent, and an organic binder in a ball mill and agitating and pulverizing the zirconia, carbon powder, and organic binder to allow the mixed zirconia powder to have nanoparticles; the carbon powder oxidization step (step S20) of heating the zirconia powder mixed with the carbon powder to a temperature of 1200 to 1800° C. and oxidizing the carbon powder to a concentration of 10 to 40 wt % to allow the porous surfaces to be formed on every particle of the zirconia powder; and the degreasing step (step S30) of putting a dispersing agent and a solvent in the zirconia powder whose particles have the porous surfaces to make a zirconia solution and removing the organic binder from the zirconia powder.
