  • Systems, methods, apparatuses, and computer-readable storage media for designing and manufacturing custom dental preparation guides
    Patent number: 8954181
    Abstract: A dental Computer-aided design (CAD)/Computer-aided manufacturing (CAM) system forms a custom dental preparation guide for guiding a dental tool that alters a shapes a tooth structure to which a custom prosthetic dental item is to be attached. The system acquires an optical measurement and an x-ray of at least one dental structure. The system correlates the acquired optical measurement and the x-ray to form a model of the at least one dental structure. The system generates a model of a reduced tooth structure based on the model of the at least one dental structure. The system also provides at least one dental preparation guide based on the model of the reduced tooth structure.

  • Method, system, and computer-readable medium for uncovering and planning an accurate dental preparation
    Patent number: 8897526
    Abstract: A procedure for creating a dental prosthetic includes registering three-dimensional (3D) dental impression image data of a tooth restoration site and 3D x-ray image data of the tooth restoration site, and removing image data corresponding to soft tissue in the tooth restoration site from the 3D dental impression image data. A system for producing a dental prosthetic includes at least one processor operable to register 3D dental impression image data of a tooth restoration site and 3D x-ray image data of the tooth restoration site and remove image data corresponding to soft tissue in the tooth restoration site from the 3D dental impression image data.
