Abstract

The present invention relates to a placement device for a dental component, a method for handling a dental component with a placement device, a dental component for placement with a placement device and a set comprising a placement device and a dental component. The placement device (1) for a dental component (2) is preferably an implant and comprises a proximal end (11), a distal end (12) and a coupling mechanism (20) for coupling the distal end (12) to the dental component. The coupling mechanism includes at least one movable pin (21) having a longitudinal axis (A1) and being movable along its longitudinal axis (A1) relative to the placement device (1) for engaging the dental component. It also includes at least one engagement part (28) at the distal end of the placement device (1) for engaging the dental component, the engagement part having a longitudinal axis (A2). A secure interlock between the dental component and the placement device is achieved by arranging the longitudinal axis (A2) of the engagement part (28) at an angle (α) relative to the longitudinal axis (A1) of the movable pin (21).

First claim

The invention claimed is:

1. A placement device for a dental component, the placement device comprising a proximal end, a distal end and a coupling mechanism for coupling the distal end to the dental component in order to allow the application of force and torque, wherein the coupling mechanism includes:
at least one movable pin having a longitudinal axis and being movable along its longitudinal axis relative to the placement device for engaging a proximal end of the dental component;
at least one engagement part at the distal end of the placement device for engaging the proximal end of the dental component, the engagement part having a longitudinal axis, wherein
the longitudinal axis of the engagement part is arranged at an angle relative to the longitudinal axis of the movable pin.

2. The placement device according to claim 1 , wherein the engagement part is aligned along a longitudinal axis of the placement device.

3. The placement device according to claim 1 , wherein the coupling mechanism further comprises an actuation member for moving said movable pin between a retracted position and an engaged position.

4. The placement device according to claim 3 , wherein the actuation member is adapted to apply a rotation to the movable pin.

5. The placement device according to claim 3 , wherein the actuation member further comprises a drive mechanism for at least assisting in an extension and/or retraction of said movable pin.

6. The placement device according to claim 1 , wherein the angle between the longitudinal axis of said movable pin and the longitudinal axis of said engagement part is between 3° to 80°.

7. The placement device according to claim 1 , further comprising a locking mechanism arranged to lock the position of the movable pin in at least one of its retracted position and engaged position.

8. A dental component for coupling to a placement device according to claim 1 , the dental component comprising a proximal end and a distal end, the proximal end constituting an interface for the placement device, wherein the interface comprises:
at least one first engagement section having a first longitudinal axis defined therethrough, the first engagement section being for interacting with a movable pin of the placement device, and
at least one second engagement section having a second longitudinal axis defined therethrough, the second engagement section for interacting with an engagement part of the placement device,
wherein the first longitudinal axis is arranged at an angle relative to the second longitudinal axis.

9. The dental component according to claim 8 , wherein the first engagement section is arranged within the second engagement section.

10. An implantation set comprising a placement device according to claim 1 and a dental component comprising a proximal end and a distal end, the proximal end constituting an interface for the placement device, wherein the interface comprises:
at least one first engagement section having a first longitudinal axis defined therethrough, the first engagement section being for interacting with a movable pin of the placement device, and
at least one second engagement section having a second longitudinal axis defined therethrough, the second engagement section for interacting with an engagement part of the placement device,
wherein the first longitudinal axis is arranged at an angle relative to the second longitudinal axis.

11. A method for handling a dental component with a placement device, according to claim 1 , comprising the steps:
moving the placement device along or about a first axis for engaging at least one engagement part situated at a distal end of the placement device with a second engagement section of the dental component,
inserting at least one movable pin of the placement device into a first engagement section of the dental component along or about a second axis,
wherein an orientation of a longitudinal axis of the engagement part differs from the orientation of a longitudinal axis of the movable pin.

12. The method according to claim 11 , wherein the engagement of the engagement part releases a locking mechanism of the placement device for enabling a movement of the movable pin.

13. The method according to claim 11 , wherein at least one of the insertion and the retraction of the movable pin is at least assisted by a drive mechanism.

14. The method according to claim 13 , wherein the insertion of the movable pin into the first engagement section biases the drive mechanism for retracting the movable pin.

15. The method according to claim 13 , wherein the drive mechanism is activated by an actuation member.
