  • Patent number: 10383709
    Abstract: An overdenture bar includes a U-shaped support beam configured to being coupled to a plurality of dental implants and extending generally above the mucus membrane of the gums. The U-shaped support beam has an anterior region and a pair of posterior extensions. At least one portion of the U-shaped support beam includes a plurality of retention elements extending generally normal to an outer surface of the U-shaped support beam in a plurality of directions. A method for producing a dental bar model on a CAD/CAM program to be fitted on a patient's upper or lower gingival surface includes the steps of selecting a longitudinal portion of the bar, adding protrusions to an upper portion of the bar and/or positioning a buccal finish line and a lingual finish between two boundary lines. The boundary lines illustrate the highest and lowest position of the finish lines.

  • Patent number: 9179988
    Abstract: Presented herein are methods, systems, devices, and computer-readable media for dental prosthesis connector design. Embodiments include providing a computer-based interface for manipulating a connector that connects a first dental restoration component and a second dental restoration component in a dental prosthesis; providing, via a cross-sectional representation of the connector, an acceptability design constraint for the connector, such as whether the connector meets production constraints and/or encompasses the intersection between neighboring teeth; modifying the connector based on operator input; determining whether the modified connector is acceptable with respect to the acceptability design constraint; and providing an acceptability indication for the modified connector, wherein said the acceptability indication is determined based at least in part on whether the modified connector is acceptable with respect to the acceptability design constraint.

  • Publication number: 20100267376
    Abstract: The invention provides methods and devices for configuring or displaying parameters of an accessory device at a connected device. A template file including parameters and associated user interface components is stored at the accessory and transmitted when required, and the receiving device may, based on this template file and current parameter values received in a separate message, create a user interface for display and/or configuration of parameters.
