METHOD FOR MANUFACTURING ZIRCONIA BLOCK FOR DENTAL PROSTHESIS HAVING LAYERED COLOR GRADIENT BY WATER ABSORPTION RATE
The present invention relates to a method for manufacturing a zirconia block for a dental prosthesis having a layered color gradient by a water absorption rate, in which the permeation degree of a coloring solution is controlled by setting a different particle size of powder for each layer of the zirconia block on the basis of the property that the amount of water absorption per hour is differentiated according to the particle size of powder, and as a result, the zirconia block is constituted so as to realize an esthetically excellent resultant product with the same color as natural teeth without carrying out the existing coloring liquid process for zirconia.
