Publication number: 20230380943Abstract: Disclosed are example embodiments of a milling bur specifically designed to mill a dental prosthesis from a full-sintered zirconia blank. The milling bur comprises a milling tip configured to have a factor of safety of at least 2 by having a first coverage-percentage of grinding particles covering a surface area of the tip of the milling bur. The factor of safety is a number of times the milling bur can fully mill a dental prosthesis from a fully-sintered zirconia blank.Type: ApplicationFiled: August 3, 2023Publication date: November 30, 2023Applicant: James R. Glidewell Dental Ceramics, Inc.Inventors: Marco A. Jokada, Vaheh Golestanian Nemagrdi, Kenad Destanovic, Marshall L. Fernald, David C. Leeson

Publication number: 20210322139Abstract: A machinable preform for shaping into dental restorations is described that comprises material having suitable strength for use in dental applications without requiring further processing after shaping to strengthen the material (such as sintering). In one embodiment, a preform is comprised of a machinable dental material having a Vickers hardness value in the range of 4 HV GPa to 20 HV GPa, and comprises a body and a stem that extends from the outer surface of the body that supports the body during shaping. A method for making the machinable preform, and a kit comprising a machinable preform and a grinding tool, are also described.Type: ApplicationFiled: June 28, 2021Publication date: October 21, 2021Inventors: David C. Leeson, Marco A. Jokada, Vaheh Golestanian Nemagrdi, Hossein Madanipour
