Abstract

A system that includes a gingiva former, a final abutment, and a final implant replacement. The gingiva former includes connecting geometry for attachment to an implant, a customized edge, a tapered bottom portion, and a tapered top portion that includes a circumferential surface. The customized edge and the tapered bottom portion have respective shapes that correspond to a 3D data set of a region of the final abutment that includes and is below an edge of the final abutment. The circumferential surface and a longitudinal axis of the connecting geometry form an angle of inclination. The customized edge of the gingiva former either (i) corresponds to a gingival line of the final implant replacement or (ii) is at a distance from the gingival line of the final implant replacement such that the gingival line of the final implant replacement is above the edge of the gingiva former.

First claim

The invention claimed is:

1. A dental system, comprising:
a gingiva former that includes a gingiva former edge, a top portion, and a bottom portion,
wherein the bottom portion of the gingiva former includes a connecting geometry configured to attach the gingiva former to an implant and a peripheral surface, and
wherein the top portion of the gingiva former includes a top surface and a peripheral surface that extends from the gingiva former edge to the top surface,
wherein at least a portion of the peripheral surface of the top portion is tapered towards the longitudinal axis of the connecting geometry at a tilt angle of 0.5° to 30°, with the taper starting at the gingiva former edge,
wherein at least a portion of the peripheral surface of the bottom portion of the gingiva former between an implant shoulder and the gingiva former edge is a concave surface such that, starting at the gingiva former edge and moving towards the implant shoulder, a distance from the peripheral surface of the bottom portion of the gingiva former to the longitudinal axis decreases; and

a final abutment that includes a final abutment edge and a region below the final abutment edge,
wherein a geometry of the gingiva former edge corresponds to a geometry of the final abutment edge, and
wherein a geometry of the region below the final abutment edge corresponds to a geometry of the bottom portion of the gingiva former.

2. The dental system according to claim 1 , wherein the portion of the peripheral surface of the top portion has a linear profile at a constant pitch.

3. The dental system according to claim 1 , wherein the gingiva former is formed from a plastics-based material.

4. A dental system, comprising:
a gingiva former that includes a gingiva former edge, a top portion, and a bottom portion,
wherein the bottom portion includes a connecting geometry configured to connect the gingiva former to an implant and a peripheral surface,
wherein a portion of the peripheral surface between an implant shoulder and the gingiva former edge is concave starting at the gingiva former edge and moving towards the implant shoulder, and
wherein the top portion includes a tapered peripheral surface, with the taper of the peripheral surface starting at the gingiva former edge; and

a final abutment that includes a final abutment edge and a region below the final abutment edge,
wherein a geometry of the final abutment edge corresponds to a geometry of the gingiva former edge, and
wherein a geometry of the region below the final abutment edge corresponds to a geometry of the bottom portion of the gingiva former.

5. The dental system according to claim 1 , further comprising:
a final implant replacement,
wherein the gingiva former edge either: (i) corresponds to a gingival line of the final implant replacement, or (ii) is at a distance from the gingival line of the final implant replacement such that the gingival line of the final implant replacement is relatively above the gingiva former edge.

6. The dental system according to claim 1 , further comprising:
a final implant replacement,
wherein a bottom portion of the final implant replacement has the geometry of the bottom portion of the gingiva former.

7. The dental system according to claim 6 , wherein the final implant replacement is a single piece entity.

8. The dental system according to claim 6 , wherein the final implant replacement is a multi-piece entity.

9. The dental system according to claim 1 , wherein the bottom portion of the gingiva former is a same size as the region below the final abutment edge of the final abutment.

10. The dental system according to claim 1 , further comprising:
a final implant replacement,
wherein a portion of the final implant replacement is shaped to produce a deviating emergence profile when the final implant replacement is attached to a dental implant.

11. The dental system according to claim 4 , further comprising:
a final implant replacement,
wherein the gingiva former edge either: (i) corresponds to a gingival line of the final implant replacement, or (ii) is at a distance from the gingival line of the final implant replacement such that the gingival line of the final implant replacement is relatively above the gingiva former edge.

12. The dental system according to claim 4 , further comprising:
a final implant replacement,
wherein a size and shape of a bottom portion of the final implant replacement is the same as the size and shape of the bottom portion of the gingiva former.

13. The dental system according to claim 12 , wherein the final implant replacement is a single piece entity.

14. The dental system according to claim 12 , wherein the final implant replacement is a multi-piece entity.

15. The dental system according to claim 4 , wherein the gingiva former is formed from a plastic based material.

16. The dental system according to claim 4 , further comprising:
a final implant replacement,
wherein a portion of the final implant replacement is shaped to produce a deviating emergence profile when the final implant replacement is attached to a dental implant.

17. A dental system, comprising:
a gingiva former that includes a gingiva former edge that divides the gingiva former into a top portion and a bottom portion, with the top portion including a peripheral surface that tapers towards a longitudinal axis of the gingiva former, with the taper of the peripheral surface starting at the gingiva former edge, and with the bottom portion including a peripheral surface that decreases in distance from the longitudinal axis starting at the gingiva former edge,
wherein the bottom portion of the gingiva former includes a connecting geometry; and
a final abutment that includes a final abutment edge and a region below the final abutment edge, wherein a geometry of the final abutment edge corresponds to a geometry of the gingiva former edge, and wherein a geometry of the region below the final abutment edge corresponds to a geometry of the bottom portion of the gingiva former.
