  • Patent number: 11957524
    Abstract: A dental prosthetic positioning assembly comprises an occlusal assembly and a maxillary arch subassembly. The occlusal assembly includes a maxillary tray configured to be formed in a patient's maxillary alveolar ridge, wherein the maxillary tray comprises a occlusal rim component. The occlusal assembly further includes a carriage frame component composed of biocompatible magnetic metal material anchored to the maxillary tray. The maxillary arch subassembly comprises a plurality of prosthetic maxillary teeth components magnetically anchored to the occlusal rim component. The carriage frame component is moveable with respect to the maxillary tray. The prosthetic maxillary teeth components are individually moveable with respect to each other to achieve a desired dental positioning.

  • Publication number: 20170020638
    Abstract: A collaborative approach, incorporating a server for data transmission, security verification, and authentication verification, is implemented between a dental office and a dental laboratory to fabricate a designed dental restoration. A scanner is used in a dental office to take a scan of a patient's mouth. The dental laboratory designs the dental restoration with specialized design software taking into account the scan of the mouth as well as a prescription from the dental office. The parameters defining the designed dental restoration are contained in a design file. The design file is used to create milling specifications defining instructions for milling the designed dental restoration. The materials for the dental restoration are loaded into a mill, where the dental restoration is fabricated in accordance with the milling specifications. Security verification ensures authorized materials are used, and authentication verification ensures authorized materials and processes are used.
