Abstract

The present invention relates to a method of attaching a dental component having an angulated screw channel to a dental implant. The present invention also relates to a dental component having an angulated screw channel and a metal adapter.

Claims

1. A method of attaching a dental component to a dental implant,

the dental component comprising:

a component body, wherein the component body comprises a screw channel passing through the component body and forming a first opening at a first end and a second opening at an apical end, and a screw seat proximal to the apical end of the screw channel for seating the head of a screw for the fixation of the dental component to the dental implant, wherein the longitudinal axis of the screw channel at the first end does not match the longitudinal axis of the screw channel at the apical end; and

a metal adapter attachable to the component body, wherein the metal adapter comprises a bore passing through the metal adapter and forming a coronal opening and an apical opening,

which method comprises;

providing the component body without the metal adapter;

inserting the screw into the screw channel through the first opening, and passing the screw through the screw channel so that a portion of the screw opposite said head protrudes through the second opening at the apical end of the screw channel;

attaching the metal adapter to the component body as said portion of the screw protrudes through the second opening; and

attaching the component body with the attached metal adapter to the dental implant, and fixing the component body with the attached metal adapter to the dental implant using the screw.

2. The method according to claim 1, wherein the head of the screw is seated on the screw seat as said portion of the screw protrudes through the second opening.

3. The method according to claim 1, wherein the metal adapter is adapted to be attached to the apical end of the component body, and wherein the bore of the metal adapter is aligned with the screw channel at the second opening when the metal adapter is attached to the component body.

4. The method according to claim 1, wherein the metal adapter has a conical connection interface for attachment to the dental implant, and wherein the conical connection interface includes an external conical shape tapering towards the apical end of the metal adapter, and an external indexed portion provided apically of the conical shape adjacent to the apical end of the metal adapter.

5. The method according to claim 1, wherein the metal adapter includes at least one convex lobe adapted to abut against at least one corresponding concave recess in the component body for preventing rotation between the component body and the metal adapter, and wherein said at least one convex lobe extends apically of an apical end of the component body when the metal adapter is attached to the component body.

6. The method according to claim 1, wherein the metal adapter is removably attachable to the component body, for example by means of friction-fit and/or snap-locking.

7. The method according to claim 1, wherein the metal adapter comprises at least one flexible arm with a protrusion adapted to press against a side wall and/or snap into any corresponding undercut of the component body for securing the metal adapter to the component body in the coronal-apical direction.

8. The method according to claim 1, wherein the component body is adapted to support a dental restoration.

9. The method according to claim 1, wherein the component body is a full-contour part.

10. The method according to claim 1, wherein the component body is ceramic.

11. The method according to claim 1, wherein the dental implant is arranged in a physical model, and wherein the dental implant optionally is a replica.

12. The method according to claim 1, wherein the dental implant is anchored in a jaw bone of a patient.

13. A dental component for attachment to a dental implant, the dental component comprising:

a ceramic component body, wherein the component body comprises a screw channel passing through the component body and forming a first opening at a first end and a second opening at an apical end, and a screw seat proximal to the apical end of the screw channel for seating the head of a screw for the fixation of the dental component to the dental implant, wherein the longitudinal axis of the screw channel at the first end does not match the longitudinal axis of the screw channel at the apical end; and

a metal adapter removably attachable to the component body, wherein the metal adapter comprises a bore passing through the metal adapter and forming a coronal opening and an apical opening.

14. (canceled)

15. A dental system comprising:

a dental implant; and

a dental component comprising;

a ceramic component body, wherein the component body comprises a screw channel passing through the component body and forming a first opening at a first end and a second opening at an apical end, and a screw seat proximal to the apical end of the screw channel for seating the head of a screw for the fixation of the dental component to the dental implant, wherein the longitudinal axis of the screw channel at the first end does not match the longitudinal axis of the screw channel at the apical end, and

a metal adapter removably attachable to the component body, wherein the metal adapter comprises a bore passing through the metal adapter and forming a coronal opening and an apical opening.
