  • Patent number: 11523888
    Abstract: An additively manufactured dental crown with a wall having a bottom edge and an occlusal portion joined with the wall opposite the bottom edge. The wall and occlusal portion form an interior surface and an opposing exterior surface. By using additive manufacturing and materials for such, the dental crown can have thin walls with a thickness of less than 300 microns at the thinnest portion of it and can include fine printed features such as identifiers, internal ribs, slots, porous meshes, and retention elements.

  • Patent number: 10820971
    Abstract: A method of making a dental restoration has the step of providing a precursor of the dental restoration. The dental restoration has at least a first and a second surface portion which are delimited by a physical boundary structure. The method further has the steps of applying a first coloring solution associated with the first surface portion onto the first surface portion, sintering the dental restoration precursor, and removing the physical boundary structure.

  • Publication number: 20180071062
    Abstract: A method of making a dental restoration has the steps of providing a three-dimensional model of a dental restoration, providing a three-dimensional virtual model (21) of an anterior incisal portion of a patient's tooth, superimposing the dental restoration model and the incisal portion model (21), and automatically recessing the dental restoration model, and thereby creating a reduced dental restoration model. The method helps combining the advantages of monolithic dental restorations and manual finishing.

  • Patent number: 9125712
    Abstract: One embodiment of the present disclosure is directed to a method used in the making of a dental restoration, which comprises the steps of determining a tooth flat at a patient's tooth, and evaluating the tooth flat to provide a geometric characteristic data of the first tooth flat. The characteristic data are used to provide a computer model of a jaw motion under occlusal contact between teeth in the patient's upper and lower jaws. In one embodiment, the method helps facilitating the preparation of dental restorations.

  • Patent number: 8770975
    Abstract: A method of making a dental restoration is provided. The dental restoration comprises a frame and a veneer. An inner veneer surface and an outer frame surface are adapted to be mated with one another to form the dental restoration. The method in particular comprises steps of (a) providing an outer veneer surface; (b) determining an outer frame surface, based on the outer veneer surface; (c) determining an inner veneer surface, based on the outer frame surface; and (d) providing an inner frame surface, based on a natural tooth surface. The method may be advantageous for rapid, precise and inexpensive manufacturing of a dental restoration.

  • Publication number: 20120296613
    Abstract: A method for designing a dental restoration of a type comprising a dental implant, a dental super structure, and a dental abutment for connecting the implant and the super structure. The method comprises the steps of retrieving a predetermined computer model of an abutment, using a user-created computer representation of a surface of the dental implant for providing a computer representation of an implant receiving surface, and for providing the predetermined abutment model with the implant receiving surface representation to provide a user-adapted abutment model. The method may help minimizing the time and costs in the preparation of a dental restoration.
