Abstract

A system for attaching a natural tooth to a dental implant includes a dental prosthesis and an elastomeric cushion. The elastomeric cushion is positioned in contact, either directly or indirectly, with at least a portion of the dental implant and at least a portion of the dental prosthesis such that the elastomeric cushion permits movement of the dental prosthesis relative to the dental implant in response to movement of the natural tooth transferred through the dental prosthesis.

Claims (36)

1. A dental bridge system for connecting a natural tooth to a dental implant, said system comprising:

a dental prosthesis having a natural tooth crown comprising a cap structure configured to be semi-permanently fixed to a natural tooth and having a key received within a portion of a dental implant; and

an elastomeric cushion positioned between the dental implant and said key, said elastomeric cushion configured and positioned such that said dental prosthesis and said dental implant do not directly contact one another and such that said elastomeric cushion permits a range of movement of said dental prosthesis relative to the dental implant in response to on-going movement of the natural tooth from time to time during use of the dental bridge system, wherein said range of movement corresponds with the anticipated range of movement of the natural tooth during use of the dental bridge system.

2. The system according to claim 1 wherein said elastomeric cushion is fixed to said key.

3. The system according to claim 1 wherein said elastomeric cushion is made from a material selected from the group consisting of rubber, silicone, nylon, polyethylene, copolymers, plastic, compolymers, elastomers, santoprene, high density polyethylene, cross-linked polyethylene, and polyoxymethelene.

4. The system according to claim 1 wherein said elastomeric cushion is made from more than one material.

5. The system according to claim 4 wherein said elastomeric cushion further comprises zones of said more than one material.

6. The system according to claim 1 wherein said elastomeric cushion is configured and positioned to permit said dental prosthesis to move about 0.1 mm to about 2.5 mm relative to the dental implant.

7. The system according to claim 1 wherein said key further comprises a horizontal extension and a vertical arm.

8. The system according to claim 1 wherein said key further comprises a bulbous distal end.

9. The system according to claim 1 wherein said dental prosthesis further comprises at least one pontic between said natural tooth crown and said key.

10. A dental bridge system comprising:

a dental prosthesis having a natural tooth crown comprising a cap structure configured to be semi-permanently fixed to a natural tooth and having a key;

a dental implant having a notch that receives said key; and

an elastomeric cushion positioned between said key and said dental implant, said elastomeric cushion configured and positioned such that said dental prosthesis and said dental implant do not directly contact one another and such that said elastomeric cushion permits a range of movement of said dental prosthesis relative to said dental implant in response to on-going movement of the natural tooth from time to time during use of the dental bridge system, wherein said range of movement corresponds with the anticipated range of movement of the natural tooth during use of the dental bridge system.

11. The system according to claim 10 wherein said dental implant further comprises an exposed portion and an implant crown, and wherein said notch extends into said implant crown and said exposed portion.

12. The system according to claim 10 wherein said elastomeric cushion is fixed in said notch.

13. The system according to claim 10 wherein said notch holds said elastomeric cushion in place by an interference fit.

14. The system according to claim 10 wherein said elastomeric cushion is fixed to said key.

15. The system according to claim 10 wherein said elastomeric cushion is made from a material selected from the group consisting of rubber, silicone, nylon, polyethylene, copolymers, plastic, compolymers, elastomers, santoprene, high density polyethylene, cross-linked polyethylene, and polyoxymethelene.

16. The system according to claim 10 wherein said elastomeric cushion is made from more than one material.

17. The system according to claim 16 wherein said elastomeric cushion further comprises zones of said more than one material.

18. The system according to claim 10 wherein said elastomeric cushion permits said dental prosthesis to move about 0.1 mm to about 2.5 mm relative to said dental implant.

19. The system according to claim 10 wherein said key further comprises a horizontal extension and a vertical arm.

20. The system according to claim 10 wherein said key further comprises a bulbous distal end.

21. The system according to claim 10 wherein said dental prosthesis further comprises at least one pontic between said natural tooth crown and said key.

22. A method of bridging a natural tooth to a dental implant, said method comprising:

providing a dental prosthesis, wherein said dental prosthesis has a natural tooth crown comprising a cap structure and said dental prosthesis has a key;

installing a dental implant, wherein said dental implant has a notch configured to receive said key;

providing an elastomeric cushion;

semi-permanently securing said natural tooth crown to a natural tooth;

positioning said elastomeric cushion between said key and said dental implant;

inserting said key into said notch; and

wherein said dental prosthesis and said dental implant do not directly contact one another and said elastomeric cushion permits a range of movement of said dental prosthesis relative to said dental implant in response to on-going movement of the natural tooth from time to time during use of the dental prosthesis, wherein said range of movement corresponds with the anticipated range of movement of the natural tooth during use of the dental prosthesis.

23. The method according to claim 22 further comprising securing said elastomeric cushion in said notch.

24. The method according to claim 22 further comprising securing said elastomeric cushion to said key.
