Healing abutment and method for producing a design of a healing abutment

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.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT

(7) FIG. 1 shows a customized healing abutment 1 of the invention. It comprises a customized edge 2 that corresponds to the edge of a customized final abutment 3 indicated by dashed lines.

(8) A bottom portion 4 of the healing abutment located below the edge 2 possesses a connecting geometry 5 for attachment thereof to an implant 10 shown in FIG. 2, which connecting geometry 5 comprises a bottom attachment surface 6 and internal attachment surfaces. The bottom portion 4 further comprises a likewise customized external surface 7 that is disposed between the connecting geometry 5 and the customized edge 2 and that corresponds to the external surface of the customized final abutment 3 in the region below the edge 2.

(9) Thus the bottom portion of the healing abutment is exactly the same as the geometry of the final abutment 3.

(10) A top portion 8 of the healing abutment 1 that is located above the edge 2 is configured so as to be tapered such that a peripheral surface 9 of the top portion 8 and a longitudinal axis A of the connecting geometry 5 form a tilt angle ranging from 0.5 to 30 at all points. Thus the shape of the healing abutment 1 in the region above the edge 2 differs from that of the final abutment 3. While the final abutment 3 comprises a shoulder, more specifically a camber, directed toward the longitudinal axis A of the connecting geometry, the peripheral surface 9 of the gingival former 1 extends in the exemplary embodiment shown as a straight line in the direction of the longitudinal axis A and at a constant pitch.

(11) FIG. 2 shows the healing abutment 1 attached to the implant 10, which has been inserted into a jawbone 11 in a preparation area of an individual patient, as represented diagrammatically in the figure, and the connecting geometry 5 for attachment to the implant 10 protrudes above the jawbone 11 along the longitudinal axis A, in this exemplary embodiment. The bottom portion of the healing abutment 1 including the connecting geometry 5, the external surface 7, and the edge 2 is surrounded by gingival tissue 12. Following the insertion of the healing abutment 1, the gingival tissue 12 can thus assume a shape corresponding to that of the customized final abutment 3 to be subsequently inserted.

(12) Also, the emergence profile, namely the area between the implant shoulder 15 and the gingival line 16 of the final implant replacement, is formed such that it largely corresponds to the final emergence profile. Only in the region of the gingival line 16 is the emergence profile for the healing abutment caused to deviate somewhat from the final emergence profile by way of the tapered geometry of the top portion of the healing abutment 1. When the healing abutment is inserted, the gingival line 16 either corresponds precisely to the profile of the edge 2 of the healing abutment 1, as shown in FIG. 2, or it overlaps the edge 2 thereof, as shown in FIG. 3. The tapered geometry of the top portion 8 of the healing abutment 1 then enables the gingival tissue to grow laterally to above the edge 2 of the healing abutment 1 during the healing phase.

(13) Thus while the shape of the gingiva 12 in the region of the bottom portion 4 following the removal of the healing abutment 1 corresponds to the shape of the final abutment 3 to be inserted, the tapered top portion of the healing abutment above the edge 2 thereof causes the gingiva 12, on removal of the healing abutment 1 and the insertion of an implant replacement 13, to assume a shape that gives rise to a deviating emergence profile, namely, to a surplus 14 of gingiva 12 all around the implant replacement 13 above the edge 2.
