Abstract

Methods of taking an impression or scan of a patient'"'"'s oral cavity without requiring removal of a healing cap coupled within the implant in the subgingival void. The method may include providing an anatomical healing cap received within the subgingival void of a given tooth position, where the anatomical healing cap is coupled into an implant in the void. A scanning body or an impression post is inserted into an open end (e.g., the hollow core) of the anatomical healing cap, in-situ, with the anatomical healing cap positioned in the subgingival void, and the implant thereunder (or thereover for a maxillary tooth position). The scanning body or impression post is used as a reference in making the impression or scan. Because this is done without requiring removal of the healing cap, further collapse of the gingival tissue surrounding the void is prevented.

Claims

1. A method of taking an impression or scan of a patient'"'"'s oral cavity, the method comprising:

providing an anatomical healing abutment/cap received within a subgingival void of a given tooth position, the anatomical healing abutment/cap being threadably coupled into an implant disposed adjacent the anatomical healing abutment/cap; and

providing a scanning body or impression post that is initially separate from the anatomical healing abutment/cap, and inserting the scanning body or impression post into an open end of the anatomical healing abutment/cap with the anatomical healing abutment/cap positioned in the subgingival void, such that insertion of the scanning body or impression post occurs without requiring removal of the anatomical healing abutment/cap;

wherein the scanning body or the impression post is selectively removable from the open end of the anatomical healing abutment/cap, and a screw is not required to selectively secure the scanning body or the impression post to the open end of the anatomical healing abutment/cap, such that the scanning body or impression post is slidably received into the open end of the anatomical healing abutment/cap, and the anatomical healing abutment/cap is threadably coupled into the implant;

wherein the anatomical healing abutment/cap and the scanning body or impression post are keyed to one another;

wherein the anatomical healing abutment/cap comprises one or more vertical grooves formed into an interior surface of the anatomical healing abutment/cap;

wherein an exterior surface of the scanning body or impression post inserted into the anatomical healing abutment/cap includes one or more vertical protrusions which mate with the one or more vertical grooves of the anatomical healing abutment/cap; and

wherein;

the one or more vertical grooves comprise a plurality of vertical grooves which are of different lengths and/or widths relative to one another; and

the one or more vertical protrusions comprise a plurality of vertical protrusions which are of different lengths and/or widths relative to one another.

2. The method as recited in claim 1, wherein the one or more vertical grooves formed into an interior surface of the anatomical healing abutment/cap are formed into an interior surface of a hollow core about which the anatomical healing abutment/cap is formed.

3. The method as recited in claim 1, wherein the anatomical healing abutment/cap comprises one or more radiopaque markers.

4. The method as recited in claim 3, the method further comprising taking a scan of the patient'"'"'s oral cavity, using an imaging device.

5. The method as recited in claim 4, wherein the scan of the patient'"'"'s oral cavity is taken using CT scan.

6. The method as recited in claim 4, wherein the scan of the patient'"'"'s oral cavity is taken using x-ray.

7. The method as recited in claim 4, the method further comprising applying a radiopaque powder around a gingival cuff surrounding the anatomical healing abutment/cap so that the powdered surface better shows up on the scan.

8. The method as recited in claim 1, wherein inserting the scanning body or the impression post into the anatomical healing abutment/cap comprises inserting the impression post into the anatomical healing abutment/cap, the method further comprising taking an impression of the impression post, the anatomical healing abutment/cap, and surrounding surfaces.

9. The method as recited in claim 1, wherein the plurality of vertical grooves are of different lengths relative to one another;

and the plurality of vertical protrusions are of different lengths relative to one another.

10. The method as recited in claim 1, wherein the plurality of vertical grooves are of different widths relative to one another;

and the plurality of vertical protrusions are of different widths relative to one another.

11. A method of taking an impression or scan of a patient'"'"'s oral cavity, the method comprising:

providing an anatomical healing abutment/cap received within a subgingival void of a given tooth position, the anatomical healing abutment/cap being threadably coupled into an implant disposed adjacent the anatomical healing abutment/cap; and

providing a scanning body or impression post that is initially separate from the anatomical healing abutment/cap, and inserting the scanning body or impression post into an open end of the anatomical healing abutment/cap with the anatomical healing abutment/cap positioned in the subgingival void, such that insertion of the scanning body or impression post occurs without requiring removal of the anatomical healing abutment/cap;

wherein the scanning body or the impression post is selectively removable from the open end of the anatomical healing abutment/cap, and a screw is not required to selectively secure the scanning body or the impression post to the open end of the anatomical healing abutment/cap, such that the scanning body or impression post is slidably received into the open end of the anatomical healing abutment/cap, and the anatomical healing abutment/cap is threadably coupled into the implant;

wherein the anatomical healing abutment/cap and the scanning body or impression post are keyed to one another;

wherein the anatomical healing abutment/cap comprises one or more vertical protrusions formed into an interior surface of the anatomical healing abutment/cap;

wherein an exterior surface of the scanning body or impression post inserted into the anatomical healing abutment/cap includes one or more vertical grooves which mate with the one or more vertical protrusions of the anatomical healing abutment/cap; and

wherein;

the one or more vertical grooves comprise a plurality of vertical grooves which are of different lengths and/or widths relative to one another; and

the one or more vertical protrusions comprise a plurality of vertical protrusions which are of different lengths and/or widths relative to one another.

12. The method as recited in claim 11, wherein the anatomical healing abutment/cap comprises one or more radiopaque markers.

13. The method as recited in claim 12, the method further comprising taking a scan of the patient'"'"'s oral cavity, using an imaging device.

14. The method as recited in claim 13, wherein the scan of the patient'"'"'s oral cavity is taken using CT scan.

15. The method as recited in claim 13, wherein the scan of the patient'"'"'s oral cavity is taken using x-ray.

16. The method as recited in claim 13, the method further comprising applying a radiopaque powder around a gingival cuff surrounding the anatomical healing abutment/cap so that the powdered surface better shows up on the scan.

17. The method as recited in claim 11, wherein inserting the scanning body or the impression post into the anatomical healing abutment/cap comprises inserting the impression post into the anatomical healing abutment/cap, the method further comprising taking an impression of the impression post, the anatomical healing abutment/cap, and surrounding surfaces.

18. The method as recited in claim 11, wherein the plurality of vertical grooves are of different lengths relative to one another;

and the plurality of vertical protrusions are of different lengths relative to one another.

19. The method as recited in claim 11, wherein the plurality of vertical grooves are of different widths relative to one another;

and the plurality of vertical protrusions are of different widths relative to one another.
