  • Patent number: 10813847
    Abstract: Dental prosthetic restoration coatings made of dielectric materials, methods of fabricating the same, as well as methods of testing dental prosthetic restorations are provided. A prosthetic restoration coating can include dielectric materials such as Al2O3, ZrO2, SiNx, SiC, and SiO2. Application can take place using plasma enhanced chemical vapor deposition (PECVD) methods, and alternating materials can be used to achieve desired anticorrosive, structural integrity, hardness, adhesion, and color characteristics. A testing method can include immersing a test device in solutions of differing pH, with or without abrasive steps. The cycling can include an acidic solution and a basic solution, with an optional neutral solution. As the abrasive step, a chewing simulator can be utilized.

  • Patent number: 10758326
    Abstract: A zirconia sintered body is provided in which the strength between layers of powders is improved. A flexural strength of a test sample of the zirconia sintered body, measured pursuant to JISR1601, is not less than 1100 MPa. The test sample is formed by preparing a plurality of zirconia powders, each containing zirconia and a stabilizer that suppresses phase transition of zirconia, the zirconia powders differing in a composition, layering the zirconia powders to form a zirconia composition, and sintering the zirconia composition to form a zirconia sintered body. The flexural strength is measured such that a load point is positioned at a boundary of the zirconia powders, the boundary traversing the test sample of the sintered body along a direction of load application.
