  • Methods for fabricating dental restorations
    Patent number: 10716648
    Abstract: A method of fabricating a dental restoration is provided that includes the initial step of providing a powder of a dental material. An amount of a binder is then selectively deposited onto the powder of the dental material to produce an unfinished layer of the dental material. Multiple layers of the dental material are then produced by continually providing a powder of dental material and selectively depositing an amount of a binder until a three-dimensional unfinished model is produced. The unfinished model is then separated from an amount of unaffected powder, and is sintered to produce a three-dimensional dental restoration having a functionally-graded structure.
    Type: Grant
    Filed: April 30, 2015
    Date of Patent: July 21, 2020
    Assignee: University of Louisville Research Foundation, Inc.
    Inventors: Amirali Zandinejad, Wei-Shao Lin, Dean Morton
  • Methods for fabricating dental prostheses
    Patent number: 10045839
    Abstract: Methods of fabricating dental prostheses are provided that include the steps of providing a powder of a dental material, and then selectively melting the powder of the dental material to produce a functionally graded layer of the dental material. Additional layers of functionally graded dental material are then built on top of the initial layer of dental material to thereby produce a three-dimensional dental prosthesis having a functionally graded structure and a desired physical geometry. Dental prostheses produced by the foregoing methods are also provided.
