Abstract

The invention relates to a dental implant system comprising a dental implant (28), a dental restoration part (12), a connector (24) with a central through-hole (58) and a circumferential, radially outwardly projecting collar (30) and with a screw (52) passing through the through-hole (58) by means of which at least the connector (24) may be fixedly connected with the dental implant (28), wherein the collar (30) comprises a first stop surface (26) that interacts with the dental implant (28), and a second stop surface (32) that interacts with an abutment (16) or a dental restoration part (12). The color of the collar (30), in particular the color of the connector (24), at least corresponds to a tooth color or a gingival color. The connector (24) at least partially respectively extends into the dental implant (28) and/or into the abutment (16), and substantially consists of the same material as the abutment (16) or consists of zirconium oxide.

Claims

1. A dental implant system comprising;

a dental implant,

a dental restoration part,

a connector with a central through-hole or passage and with a circumferential, radially outwardly projecting collar and with a screw passing through the passage with the aid of which at least the connector may be fixedly connected to the dental implant,

wherein at least a color of the collar, at least corresponds to a tooth color or a gingival color, and

wherein a first portion of the connector that extends from the collar, extends into the dental implant, and a second portion of the connector that extends from the collar, extends into the dental restoration part.

2. The dental implant system of claim 1, wherein a color of the connector, at least corresponds to a tooth color or a gingival color.

3. The dental implant system as claimed in claim 1, wherein the connector is fabricated of the same material as the dental restoration part.

4. The dental implant system of claim 1, wherein the wherein the connector and the dental restoration part are fabricated of zirconium oxide, glass ceramics, titanium, a composite or plastic.

5. The dental implant system of claim 4 wherein the connector and the dental restoration part are free of metal and have substantially the same coefficient of thermal expansion.

6. The dental implant system as claimed in claim 1, wherein the second portion of the connector comprises an outer symmetry that deviates from a round shape or at least comprises a protrusion or a profiling that prevents the dental restoration part from twisting relative to the connector.

7. The dental implant system as claimed in claim 1, wherein the collar comprises a greatest height (H) that extends parallel to the longitudinal axis of the connector, of up to about 0.3 mm to about 10 mm.

8. The dental implant system as claimed in claim 7, wherein the greatest height (H) is from about 0.5 mm to about 4 mm.

9. The dental implant system as claimed in claim 1, wherein an outer diameter of the collar is conically shaped in a direction that runs in the same direction as the second portion of the connector.

10. The dental implant system as claimed in claim 1, wherein a transition area between the collar and the second portion is square shaped, or at least is formed having a radius of about 1 mm to about 5 mm and/or at least comprising a conical, circumferential surface.

11. The dental implant system as claimed in claim 1, wherein an outer surface of the second portion and/or at least one inner surface of the dental restoration part is provided with a surface profiling or pattern that comprises undercuts.

12. The dental implant system as claimed in claim 1, wherein the dental restoration part comprises an abutment and/or a crown.

13. The dental implant system as claimed in claim 1, wherein the mounting of the connector, or of the connector and the abutment, or of the connector, the abutment and the crown, on the dental implant comprises a screw, wherein the head of the screw is supported on the connector or the abutment or the crown.

14. The dental implant system as claimed in claim 1, wherein the connector and the abutment and/or the abutment and the crown are connected with one another by gluing or soldering.

15. The dental implant system as claimed in claim 1, wherein the abutment or the crown, or the abutment and the crown comprise a central pass-through recess or through-hole through which a tool for the screw may at least partially pass through.

16. The dental implant system as claimed in claim 1, wherein the abutment comprises zirconium oxide, glass ceramics, titanium, a composite or plastic, and wherein the second portion of the connector and the crown comprises glass ceramics, zirconium oxide, a composite or plastic.

17. The dental implant system as claimed in claim 1, wherein at least the collar of the connector has a thin coating of color or at least partially is dyed therethrough.

18. The dental implant system as claimed in claim 1, wherein an outer surface of the collar smoothly merges with the outer contour of the abutment or the crown.

19. The dental implant system as claimed in claim 4, wherein the zirconium oxide from which the connector is made, comprises a solubility of <

100 μ

g/cm2 and/or a biaxial bending strength of >

800 MPa and/or a fracture toughness of greater than or equal to about 5 MPa m^1/2.

20. A dental implant system comprising

a dental implant,

a dental restoration part, and

a connector comprising a circumferential, radially outwardly projecting collar,

wherein a color of the collar, at least corresponds to a tooth color or a gingival color, and

wherein at least one portion of the connector that extends from the collar extends into the dental restoration part, and

wherein the portion upon manufacture thereof comprises a length that is larger than the smallest height of the dental restoration part,

wherein the portion extends into the dental restoration part and wherein the portion may be shortened to the required length if applicable and necessary.

21. The dental implant system as claimed in claim 20, wherein a color of the connector, at least corresponds to a tooth color or a gingival color.
