  • Patent number: 12180123
    Abstract: The present disclosure belongs to the field of biological materials, and particularly relates to a multilayer zirconia ceramic with uniform transition and a method for preparing the same. The specific technical solution of the present disclosure is as follows: a zirconia ceramic with a formula comprising, in percentage by mass, 0-3% of lanthana, 1.5-16% of yttria, 0-2.5% of silicon carbide nano-whiskers, and 0-1.5% of a coloring agent, the balance being zirconia. Correspondingly provided are a multi-layer zirconia ceramic with uniform transition prepared using the formula and a method for preparing the same. By using the method of the present disclosure, multilayer zirconia ceramics with good and uniformly transitioning core properties can be quickly and conveniently prepared, meeting the requirements of patients with dental disorders on the use and esthetics of dentures.

  • Patent number: 11858867
    Abstract: The present disclosure relates to the field of dental material treatment, and particularly to a dental zirconia treatment technology. The specific technical solution is as follows: a zirconia treatment method, mainly involving color masking the zirconia, surface roughening the zirconia, coloring the zirconia, surface protection treatment and additional protective film treatment. Based on this treatment method, a brand-new color masking liquid, coloring liquid and adhesive solution are proposed. The present zirconia treatment technology not only meets the individualized requirements of patients for teeth, but also meets the requirements of dentists for convenient operation, so that it is of great value in application and popularization on the market.

  • Publication number: 20230113425
    Abstract: The disclosure relates to the technical field of medical computer-aided designs, and particularly relates to an oral digital impression instrument that includes a set of computer-readable instructions configured to implement an intelligent design method of a digital model. The method includes the steps of data acquisition, data preprocessing, intelligent design, alternative dental crown matching, dental pattern adjustment and the like. A to-be-produced tooth is rapidly and accurately produced through extracting a distance between teeth adjacent to the to-be-produced tooth, buccal and lingual dental arch crown curves, an occlusal gum diameter height and cusp pit and fissure ridge shape features of opposite jaws, and performing intelligent matching and adjusting alternative dental crown models, so that the denture processing speed is increased and intermediate links in the processing are reduced.
