    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.

    Abstract: A dental zirconia system to produce translucent zirconia sintered bodies comprises at least two separate zirconia green bodies. At least one zirconia green body comprises zirconium oxide and a lower content of at least one other oxide summing to between 6.5 wt % to 20 wt % based on a total weight percent of the zirconia green body. At least another zirconia green body comprises zirconium oxide and a higher content of at least one other oxide summing to between 7.5 wt % to 20 wt % based on a total weight percent of the zirconia green body. The at least two zirconia green bodies each have at least some particles with a diameter of 100 nanometers to 1000 nanometers. The at least two zirconia green bodies have different amounts of the at least one other oxide with respect to one another.

    Abstract: A method of making a translucent colored zirconia dental restoration comprises obtaining a zirconia green body, forming a dental restoration precursor from the zirconia green body, applying a color liquid to the precursor, and sintering the restoration precursor with regular sintering in air without post HIP processing. The zirconia green body comprises between 7 wt % to 20 wt % of stabilizer based on a total weight percent, and an L* value between 10 and 20 for a sample thickness of 1 to 1.3 mm. The zirconia green body is subsequently finally sinterable with regular sintering in air without post HIP processing to produce a translucent zirconia sintered body having a total light transmittance of at least 36% and less than 50% to light with a wavelength of 400 nm, and less than 55% to light with a wavelength of 600 nm, at a thickness of 0.6 mm.

    Abstract: A method for creating a substantially accurate dental restoration from scanning a negative dental impression of a patient's teeth or a positive dental stone model of the patient's teeth includes applying a compensation rate to compensate for the shrunk or enlarged scan of the patients teeth, to the scan of the patient's teeth using the scanner to create a true dimension working file; the scan of the patient's teeth using a computer system to create a true dimension working file; or a shrunk restoration file of the restoration using a restoration fabricator. A restoration can be designed based on the scan of the patient's teeth and creating a restoration file. The restoration can be fabricated using a restoration fabricator.

    Abstract: A zirconia ceramic body for use with dental prosthetics has an L* value between 10 and 20 for a sample thickness 011 to 1.3 mm in accordance with CIE L*a*b* colorimetric system. The zirconia ceramic body can have between 6-20 wt % or 7.20 wt % of yttria based on total weight percent of the zirconia ceramic body. The zirconia ceramic body is subsequently finally sinterable to produce a translucent zirconia sintered body. In one aspect, the sintered body has a total light transmittance of at least 36% and less than 50% to light with a wavelength of 400 nm, and less than 55% to light with a wavelength of 600 nm, at a thickness of 0.6 mm, measured using a LAMBDA 35 UV/VIS Spectrophotometer manufactured by Perkin Elmer.
