摘要
The present invention relates to a method of manufacturing a matte-finish reinforced zirconia abutment suitable for digital scanning, which uses zirconia powder corresponding to standard colors on a shade guide, and thereby can conveniently provide a quality abutment that is similar to natural teeth and completely overcome the problem of titanium abutments being difficult to apply to digital scanning due to reflection of light caused by gloss, and which also greatly improves the durability of abutments by improving an overall processing method. The method consists of: a main ingredient preparation step (S10) for pulverizing zirconia into nano-sized particles; a main ingredient coloring step (S20) for preparing a main ingredient for different colors by agitating a resin color solution formed of a mixture of a coloring pigment and a compound in which at least one chemical material is mixed with the main ingredient; a molded body formation step (S30) for acquiring a molded body by introducing the main ingredient into a molding device; a first heat-treatment step (S40) for performing a first calcination on the molded body and subjecting same to furnace cooling for 3-4 hours; a second heat-treatment step (S50) for forming a composite molded body by having glass powder for impregnation and distilled water melt-infiltrated into parts partly sintered in the first calcination process; and a fitting hole formation step (S60) for punching, on top of the composite molded body, a fitting hole into which a fastening bolt to be fitted with a fixture is inserted.
