Method, system, and composition for coloring dental ceramics

Abstract

A method for coloring a porous ceramic dental body that includes: applying at least one coating of a liquid coloring composition to at least a portion of a surface area of the porous ceramic dental body, the liquid coloring composition comprising: (a) at least one opaquing agent comprising a material comprising Zn, Al, Si, or a combination thereof; (b) at least one coloring agent comprising a material comprising Fe, Ni, Cu, Mn, Co, Cr, Mo, Pr, Nd, Er, Ce, Tb, or a combination thereof, (c) at least one wetting agent; and (d) at least one solvent; and sintering the coated porous ceramic dental body to obtain a fully sintered ceramic body having a density that is at least 98% of the theoretical density.
