Abstract
A dental block for producing a dental prosthesis comprises a green body including zirconia and having a chemical composition including increasing amounts of yttria through a thickness of the green body. The green body is substantially opaque with a substantially consistent optical characteristic of non-translucency with respect to visible light across the thickness, and is subsequently millable and sinterable to form the dental prosthesis with an optical characteristic of increasing translucency through a thickness of the dental prosthesis.
