Abstract
A multi-unit abutment apparatus for prosthetic teeth includes an implant screw having a first threaded portion for engaging and anchoring in the osseous bone. An elongated extension portion has a conical bottom portion for engaging the implant screw and having a socketed top. An abutment portion has an anti-rotation portion configured to engage the socketed top of the elongated extension portion in a non-rotational arrangement. The abutment portion has a body having a screw bore in axial parallel with the elongated extension portion and the implant screw and includes a mounting portion having a seat configured for seating the prosthetic tooth at between zero and sixty degrees.

A multi-unit abutment apparatus for placing a prosthetic tooth in the osseous bone of a dental implant patient remotely from an implant screw, the apparatus comprising:
- an implant screw having a first threaded portion configured for engaging and anchoring in the osseous bone;
- an elongated extension portion configured with a conical bottom portion for engaging the implant screw and having a socketed top;
- an abutment portion having an anti-rotation portion configured to engage the socketed top of the elongated extension portion in a non-rotational arrangement;
- the abutment portion further comprising a body portion having a screw bore in axial parallel with the elongated extension portion and the implant screw;
- the abutment portion further comprising a mounting portion having a seat configured for seating the prosthetic tooth, and a fifth threaded portion configured to accept a prosthetic screw for mounting the prosthetic tooth to the abutment portion;
- and
- wherein the fifth threaded portion is between zero and sixty degrees off-axis from the elongated extension portion.
An extension apparatus for spanning a dental implant screw and a multi-unit abutment for placing one or more prosthetic teeth in the osseous bone of a dental implant patient remotely from one or more implant screws, the apparatus comprising:
- an elongated extension member having a first end and a second end;
- the first end comprising a first threaded portion configured for engaging and anchoring in a second threaded portion of the dental implant screw;
- the first end further comprising a first conical portion adjacent the first threaded portion, wherein the first conical portion is configured such that it engages over its entirety a complimentary conical portion in the dental implant screw adjacent the second threaded portion;
- the second end comprising a socketed top portion with a third threaded portion configured to receive a fourth threaded portion of a multi-unit abutment anchoring screw;
- and
- the socketed top portion further comprising a polygonal configuration to prevent rotation of the multi-unit abutment relative to the elongated extension member.
A multi-unit abutment kit apparatus, the apparatus comprising:
- a plurality of implant screws, each having a first threaded portion;
- a plurality of elongated extension portions, each configured with a conical bottom portion for engaging one of the implant screws and having a socketed top;
- a plurality of abutment portions, each having an anti-rotation portion configured to engage the socketed top of the elongated extension portion in a non-rotational arrangement;
- each of the abutment portions further comprising a body portion having a screw bore in axial parallel with the elongated extension portion and the implant screw;
- each of the abutment portions further comprising a mounting portion having a seat configured for seating the prosthetic tooth, and a fifth threaded portion configured to accept a prosthetic screw for mounting the prosthetic tooth to the abutment portion;
- and
- wherein the fifth threaded portion is between zero and sixty degrees off-axis from the elongated extension portion.
