Abstract

The invention relates to an implant ( 1 ) comprising a support structure ( 5 ) which is prepared for anchoring, following the contours of the bone, in a jaw- and/or cranial bone ( 2 ), wherein at least one integrally attached post ( 7 ) protrudes from the support structure ( 5 ), said post being designed to have a finished denture anchored thereto and the post ( 7 ) having a base ( 9 ) that is formed out of the support structure ( 5 ) and is completed by a distal end region ( 10 ) with the interposition of a radially enlarged region ( 11 ). The invention also relates to a soft tissue displacement system ( 19 ) comprising an implant ( 1 ), a manufacturing process for a soft tissue displacement system ( 19 ) and a planning process for manufacturing an implant ( 1 ).

First claim

The invention claimed is:

1. An implant comprising a support structure which is prepared for anchoring, following the contours of the bone, at a jaw and/or cranial bone, wherein a plurality of integrally attached posts project from the support structure, said plurality of posts being configured for anchoring a final denture thereto, wherein each post of the plurality of posts has a base formed from the support structure, which is completed by a conical or pyramidal tapered distal end region with the interposition of a radially enlarged region, wherein the distal end region has a rotation prevention flat portion, which is arranged in a plane, for preventing a relative rotation between the support structure and the final denture which can be anchored to the posts of the plurality of posts, and wherein the planes, in which a respective rotation prevention flat portion is arranged, are oriented parallel to each other.

2. The implant according to claim 1 , wherein the distal end region is prepared for anchoring a soft tissue holding-down device and/or for anchoring a final denture.

3. The implant, as recited in claim 2 , wherein each post of the plurality of posts is adapted to be inserted into a holding down device wherein the holding down device receives each post of the plurality of posts.

4. The implant, as recited in claim 2 , further comprising an anchoring sleeve between a post of the plurality of posts and the holding down device wherein a post of the plurality of posts is inserted in the anchoring sleeve.

5. The implant according to claim 1 , wherein the distal end region has a retention form.

6. The implant according to claim 1 , wherein the radially enlarged region is formed as a collar surrounding each post.

7. The implant according to claim 6 , wherein the collar is received in a plane through which a center axis of each post runs perpendicular.

8. The implant according to claim 1 , wherein several posts protrude from the support structure, wherein the radially enlarged regions of the several posts are arranged in a common plane.

9. A soft tissue displacement system having an implant which has a support structure which is prepared for anchoring, following the contours of the bone, in a jaw and/or cranial bone, wherein a plurality of posts protrude from the support structure, said plurality of posts being configured for anchoring a final denture thereto, wherein the soft tissue displacement system has a holding-down device which can be anchored to the posts of the plurality of posts and which is essentially plate-shaped, has at least one indentation for receiving a distal end region of the posts of the plurality of posts and is anchored to the posts of the plurality of posts, wherein the distal end region of each post of the plurality of posts has a rotation prevention flat portion, which is arranged in a plane, for preventing a relative rotation between the support structure and the holding-down device anchored to the posts of the plurality of posts and wherein the several planes are oriented parallel to each other.

10. The soft tissue displacement system according to claim 9 , wherein the holding-down device is optically and functionally adapted to adjacent teeth and adjacent soft tissue.

11. The soft tissue displacement system according to claim 9 , wherein each post of the plurality of posts is adapted to be inserted into a holding down device wherein the holding down device receives each post of the plurality of posts.

12. The soft tissue displacement system, as recited in claim 9 , further comprising an anchoring sleeve between a post of the plurality of posts and the holding down device wherein a post of the plurality of posts is inserted in the anchoring sleeve.

13. A method of manufacturing a soft tissue displacement system according to claim 9 , wherein, in a preparatory step, information on an individual dental arch shape acquired by standard measuring devices is used in order to select a specific one from a set of prefabricated standard holding-down devices, wherein an adjustment of an overall extension is subsequently made depending on patient-specific conditions.

14. A method of preparing for the manufacture of an implant that includes a support structure and a plurality of integrally attached posts which project from the support structure, each post of the plurality of posts being configured for anchoring a final denture thereto and the support structure being configured to follow contours of a jaw bone and/or cranial bone, wherein each post has a base formed from the support structure, which is completed by a distal end region with the interposition of a radially enlarged region, and wherein the distal end region has a rotation prevention flat portion, which is arranged in a plane, for preventing a relative rotation between the support structure and the final denture which can be anchored to the post, the method comprising designing each post to receive the final denture after removal of a soft tissue hold down device that is essentially plate-shaped, has at least one indentation for receiving the distal end region of each post and is anchored to each post.

15. The method, as recited in claim 14 , wherein each post of the plurality of posts is adapted to be inserted into a holding down device wherein the holding down device receives each post of the plurality of posts.

16. The method, as recited in claim 15 , further comprising placing an anchoring sleeve over a post of the plurality of posts and placing the holding down device over the anchoring sleeve.
