Abstract: The invention relates to a process for selectively treating parts of the surface of a porous dental zirconia article, the process comprising the steps of providing a liquid composition and a porous 3-dimensional dental zirconia article having an outer and inner surface, applying the liquid composition to only a part the outer surface and/or inner surface of the porous dental zirconia article, the liquid composition comprising a whitening agent comprising a phosphorous containing component, the phosphorous containing component comprising a phosphate, phosphone or phosphine moiety, with the proviso that at least one P—O unit of the phosphate, phosphone or phosphine moiety is dissociable or able to otherwise interact with zirconia. The invention also relates to a dental zirconia article obtainable or obtained by such a process and a kit of parts comprising a container containing a certain liquid composition.

Abstract: A method of making a dental restoration has the step of providing a precursor of the dental restoration. The dental restoration has at least a first and a second surface portion which are delimited by a physical boundary structure. The method further has the steps of applying a first coloring solution associated with the first surface portion onto the first surface portion, sintering the dental restoration precursor, and removing the physical boundary structure.

Abstract: A dental coloring stamp has a transfer pad for transferring a dental coloring solution to a precursor of a dental restoration. The transfer pad is at least partially formed of an open-celled elastic sponge and has a free transfer surface. The cross-section of the transfer pad is greater than a circular area of 10 mm in diameter so that a side of a dental restoration precursor can be stamped and thus colored. The invention helps facilitating the coloring of dental restorations.
