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 porousdental 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 [mu]m 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. 本发明涉及一种制备牙科氧化锆修复体的方法，该牙科氧化锆修复体具有外表面和内表面，该方法包括焙烧多孔牙科氧化锆修复体和玻璃直至多孔牙科氧化锆修复体被烧结的步骤，玻璃在焙烧步骤期间位于多孔牙科氧化锆修复体的
