Abstract
A multi-piece dental prosthesis system is provided. The system includes an implant which can be implanted into a bone of the patient, an abutment removably connected to the implant by a prosthetic screw, and a ti-base removably connected to the abutment. The system may be used to hold a crown, denture, or partial denture in place.
Claims16
A multi-piece dental prosthesis comprising:
- a unitary implant operable to be implanted into a bone of a patient, wherein the implant comprises threads on a portion of its outer surface;
- an abutment removably engaged with the implant via a prosthetic screw engaged with both the implant and the abutment, the abutment having threads on an outer portion at a rear of the abutment, the prosthetic screw removable from the implant by being unscrewed and passing through a central opening of the abutment;
- wherein a front portion of an exterior surface of the abutment defines a cross-sectional shape, and wherein the central opening of the abutment further defines a second cross sectional shape to receive a bit to axially rotate the abutment, and the central opening defining a more narrow passage from the second cross sectional shape for a threaded end of the prosthetic screw to pass through and engage directly with the interior threads of the implant;
- wherein the implant defines an opening having a matching cross-sectional shape to the abutment front portion at its top, the abutment shape and matching opening shapes engaged together, preventing axial rotation of the abutment relative to the implant;
- wherein the implant further defines a threaded opening on its interior beyond the opening having the matching cross section, the threaded opening sized to receive the prosthetic screw;
- a ti-base defining a central opening, the ti-base having threads extending into the central opening sized to engage with the threads of the abutment;
- further comprising a crown attached to the ti-base, wherein the crown defines an opening through its height in communication with the central opening of the ti-base;
- wherein a cross-section of the opening through the crown is larger than a cross section of the implant, so as to guide the implant when passed through the opening.

- and
- a ti-base defining a central opening, the ti-base having threads extending into the central opening sized to engage with the threads on the outer portion at the rear of the abutment;
- wherein the ti-base comprises a plurality of ridges on an outer surface of the ti- base;
- wherein one of the crown, the denture, or the partial denture is removably attached to the dental implant and the abutment;
- and wherein the one of the crown, denture, or partial denture defines an opening through its height in communication with the central opening of the ti-base, wherein a cross-section of the opening is larger than a cross section of the implant, so as to guide the implant when passed through the opening.
