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 has a substantially consistent optical characteristic of chroma and translucency across the thickness, and is subsequently millable and sinterable to form the dental prosthesis with an optical characteristic of decreasing chroma, increasing translucency, and decreasing strength, in one direction through a thickness of the dental prosthesis.
