Abstract

The implant is intended for introduction into an alveolar space. It is configured as an absorbable composite body made of at least a first and a second part body. The first part body is configured as a cone, truncated cone or cylinder having a body base face. The second part body is configured as a cover membrane with a membrane face, which is larger than the body base face. The cover membrane is placed on the body base face, so it projects laterally everywhere over the body base face. The first and second part body are rigidly connected to one another in the region of the mutually adjacent body base face and membrane face.

Claims

1. An implant for introduction into an alveolar space, which is configured as an absorbable composite body made of at least a first and a second part body, wherein

the first part body is configured as one of a group of a cone, a truncated cone and a cylinder having a body base face,

the second part body is configured as a cover membrane with a membrane face, which is larger than the body base face,

the cover membrane is placed on the body base face, so it projects laterally everywhere over the body base face, and

the cover membrane is slit one of once and several times in an edge region projecting over the body base face, and

the first and second part body are rigidly connected to one another in the region of the mutually adjacent body base face and membrane face.

2. An implant according to claim 1, wherein the first part body consists at least partially of a porous collagen.

3. An implant according to claim 2, wherein the collagen of the first part body has a density of 1 to 25 mg/cm³.

4. An implant according to claim 1, wherein the first part body has a core of one of the group of native, prepared bone material and synthetic replacement bone material.

5. An implant according to claim 1, wherein the first part body consists of a mixed material with a collagen fraction and a bone fraction incorporated homogenously distributed in the collagen fraction, the bone fraction being formed by one of the group of replacement bone material and comminuted native, prepared bone material.

6. An implant according to claim 1, wherein the second part body consists of a compacted collagen.

7. An implant according to claim 6, wherein the compacted collagen of the second part body is a compacted lyophilisate made of reconstituted collagen.

8. An implant according to claim 1, wherein at least one of the two part bodies consists of a material, which contains at least one bioactive constituent which is one of the group of wound-healing and promotes bone growth.

9. An implant according to claim 1, wherein at least one of the two part bodies consists of a material which contains at least one of the group of antimicrobial and antibiotically acting constituent.

10. An implant according to claim 1, wherein the composite body at least partially consists of one of the group of a gelatin and an oxidized cellulose.

11. An according to claim 1, wherein an overall height of the composite body is at least 1.6 cm.

12. An implant according to claim 1, wherein in the first part body, the body base face has a diameter of 1 cm to 1.5 cm and a cone height is between 1 cm and 3 cm.

13. An implant according to claim 1, wherein the second part body has a membrane thickness of between 0.05 cm and 0.5 cm and a membrane diameter, which is larger by 0.2 cm to 2 cm than a diameter of the body base face.

14. An implant according to claim 1, wherein the cover membrane comprises an approximately circular center portion, on the outer periphery of which at least one elongate, laterally projecting membrane wing is attached in one piece.

15. An implant according to claim 1, wherein the first part body consists at least partially of a reconstituted collagen of type 1.

16. An implant according to claim 3, wherein the collagen of the first part body has a density of 5 to 12 mg/cm³.

17. An implant according to claim 1, wherein the second part body consists of a compacted collagen having a smaller pore size than that of the collagen of the first part body and forming one of the group of a film, a foil and a compacted sponge.

18. An implant according to claim 1, wherein in the first part body, the body base face has a diameter of 1 cm to 1.5 cm and a cone height is between 1.3 cm and 1.7 cm.

19. An implant according to claim 1, wherein in the first part body, the body base face has a diameter of 1.3 cm and a cone height is between 1 cm and 3 cm.

20. An implant according to claim 1, wherein in the first part body, the body base face has a diameter of 1.3 cm and a cone height is between 1.3 cm and 1.7 cm.

21. An implant according to claim 1, wherein the second part body has a membrane thickness of between 0.05 cm and 0.5 cm and a membrane diameter which is at least 1.4 cm.
