Abstract: Disclosed herein a dental mill blank and a method of forming the dental mill blank. The dental mill blank includes a first layer of a first hard restorative material having a first translucency and a first shade, a second layer of a second hard restorative material having a second translucency and a second shade, where at least one of the following is true (1) the first translucency is different from the second translucency, (2) the first shade is different from the second shade. The first layer and the second layer form a first interface having a first curve across a first plane of symmetry of the dental mill blank, where the first curve has a different from zero curvature; and a first straight line along the entire length of a second plane of the dental mill blank, the second plane being orthogonal to the first plane of symmetry.

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.

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: The present disclosure provides for a dental mill blank and a method of forming the dental mill blank. The dental mill blank includes a first layer (102) of a first hard restorative material having a first translucency and a first shade, a second layer (104) of a second hard restorative material having a second translucency and a second shade, where at least one of the following is true: the first translucency is different from the second translucency, the first shade is different from the second shade. The first layer (102) and the second layer (104) form a first interface having a first curve (112) across a first plane of symmetry (114) of the dental mill blank, where the first curve (112) has a different from zero curvature; and a first straight line (122) along the entire length of a second plane (118) of the dental mill blank, the second plane (118) being orthogonal to the first plane of symmetry (114).
