Process for Treating a Porous Dental Zirconia Block with Coloring Solutions
Process for treating a porous dental zirconia block with a coloring solution, the process comprising the steps of providing a porous dental zirconia block having two opposing surfaces, surface U and surface L, treating the upper surface U of the porous dental zirconia block with a coloring solution A1, wherein the coloring solution is provided with a volume VA1, turning the porous dental zirconia block around, treating the lower surface L with a coloring solution A2 which is provided with a volume VA2. wherein the coloring solutions A1 and A2 comprise a solvent and coloring ions, wherein the volume of at least one of the coloring solutions A1 or A2 is applied in portions, wherein the following condition is met: Vo=ΣVAX, with x≥2, with Vo being the overall amount of coloring solution used to infiltrate the porous dental zirconia block.
