Abstract: A method of making a dental crown or bridge restoration includes forming a precursor crown outside of a patient's mouth with a first restorative material, with a buccal contour on the buccal wall substantially the same as a buccal contour on a final crown restoration, and an open space on or around at least one of the mesial side wall or the distal side wall; and filling and securing a second material, different from the first restorative material, inside the open space or pocket of the precursor crown while outside the patient's mouth, and with the precursor crown having a strength substantially equivalent to the final crown restoration, and with the buccal contour being substantially the same as the buccal contour on the final crown, prior to filling and securing the second material.

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.
