  • Patent number: 10219876
    Abstract: A method of making a customized orthodontic bracket includes steps of providing a pre-manufactured physical bracket body, providing a physical bracket base having a tooth facing side shaped according to of at least part of a patient's tooth, and joining the bracket body and at least a portion of the bracket base. The bracket base is provided using a material build-up process. The invention helps facilitating manufacturing of customized orthodontic brackets.

  • Patent number: 10136965
    Abstract: A customized orthodontic bracket system is provided. The system can include a bracket having a customized bracket bonding pad for bonding the bracket to a tooth of a patient and a bracket slot adapted to receive a customized archwire. The customized archwire is adapted to be positioned in the bracket slot to form a precise bracket slot-archwire interface. The bracket slot and the archwire when positioned in the bracket slot can be positioned substantially adjacent the tooth surface to reduce induced vertical error in tooth positioning. The bracket slot can be configured to have a bracket slot width substantially matching a cross-section of the archwire to reduce torque rotation around an axis of the archwire when positioned therein to further enhance end-of-treatment tooth positioning and reduce overall treatment time.

The system can include a bracket having a customized bracket bonding pad for bonding the bracket to a tooth of a patient and a bracket slot adapted to receive a customized archwire. The customized archwire is adapted to be positioned in the bracket slot to form a precise bracket slot-archwire interface. The bracket slot and the archwire when positioned in the bracket slot can be positioned substantially adjacent the tooth surface to reduce induced vertical error when the tooth is in a finished position and substantially parallel to the directly adjacent portion of the tooth surface to reduce bracket thickness. The bracket slot can also be configured to have a bracket slot width substantially matching a dimension of a cross-section of the archwire to reduce torque rotation around an axis of the archwire when positioned therein to further enhance end-of-treatment tooth positioning and reduce overall treatment time.

  • Patent number: 7850451
    Abstract: A set of customized orthodontic brackets are provided with slots that are arranged substantially parallel to the tooth surface. The archwire, in an as-manufactured condition, has a portion of substantial arcuate extent, which is canted relative to the occlusal plane. The brackets are designed on a computer as a combination of three-dimensional virtual objects comprising the virtual bracket bonding pad and a separate virtual bracket body retrieved from a library of virtual bracket bodies. The virtual brackets can be represented as a file containing digital shape data and exported to a rapid prototype fabrication device for fabrication of the bracket in wax or other material and casting the wax prototype in a suitable alloy. Other manufacturing techniques are also contemplated, including milling and laser sintering.
