  • Patent number: 10390908
    Abstract: A system for dental implant restoration is provided. It includes universal aligning adaptors and prosthetic components having co-operable indices, which together form a translational, integrating system which aligns, synchronizes, and references the prosthetic components about an implant's central axis of rotation. Rotation of an adaptor about a prosthetic component, with its reference point becoming aligned to a predetermined reference point on the prosthetic component, followed by the rotation of the adaptor/prosthetic component assembly about the implant, situates the prosthetic component in a predetermined position such that all other prosthetic components become synchronized to the adaptor's reference point. The prosthetic component is mechanical for clinical or lab bench use, or is virtual for restoration design in a software program, prior to milling prosthetic abutments or devices.

  • Patent number: 10383708
    Abstract: Advantageous dental analogs for dental restorations and related methods of use are provided. The present disclosure provides improved analog members for use in fabricating dental implant-supported restorations, and related methods of use. More particularly, the present disclosure provides advantageous systems/methods for the design and use of protection analog members configured to protect cuff portions of coping members during the fabrication of dental restorations. The improved analog members include an added vertical rim or collar to contact and/or protect the cuff portion of coping members when an end of the analog member is screwed/mounted into place into an end of the coping member. This way, the resin added during fabrication will not contact/adhere to the cuff portion allowing a proper seating of the finished fixed implant-supported prosthesis. Use of the improved analog member also can eliminate scratches/damage to the cuff portion (e.g., during trimming and polishing).
