Abstract: The invention relates to a process of producing a dental zirconia restoration, the dental zirconia restoration having an outer and an inner surface, the process comprising the step of firing a porous dental zirconia restoration and a glass until the porous dental zirconia restoration is sintered, the glass being located during the firing step on at least a portion of the outer surface of the porous dental zirconia restoration, wherein the zirconia material of the porous dental zirconia restoration and the glass are selected such that during the firing step the glass infiltrates the pores of the porous dental zirconia restoration to an extent of not more than 5 μm in depth. The invention also relates to a sintered dental zirconia restoration obtainable by such a process and a kit of parts comprising a porous dental zirconia mill blank and a surface treating agent containing a glass for use in such a process.

Abstract: Metal-coated zirconia articles have at least one surface that is a surface-treated surface. The surface-treated surface is a phosphate-treated surface. At least a portion of the surface-treated surface is covered with a layer of metal. The metal covering adheres more strongly to the surface-treated surface than to an identical surface that is not surface-treated.

Abstract: The invention relates to a glazing composition suitable for glazing the surface a dental zirconia article. The glazing composition comprises a liquid, glass particles, and hydrophilic silica nano-particles. The invention also relates to a process for sintering a porous dental zirconia article with a glazing composition on its surface.
