Abstract

The anchor for securing a tooth replacement comprises an anchoring part (1) which can be secured to an implant or jaw and which has a recess (2), and a pivoting part (10) to which the tooth replacement can be secured and which contains a pin (11). The pivoting part is pivotable with respect to the anchoring part when the pin is received in the recess. The anchor comprises means (15, 19) for applying a hardenable substance in the recess (2) of the anchoring part (1), in order to fix the pivoting part in a defined position of pivoting.

Claims

1. An anchor for securing a tooth replacement, comprising:

an anchoring part configured to secure to an implant or jaw and that includes a recess;

a pivoting part configured to secure to the tooth replacement the pivoting part including a pin and being

configured to be pivotable relative to the anchoring part when the pin is received in the recess; and

a fastening equipment configured to apply a hardenable substance in the recess such that the pivoting part is fastened in a pivoting position.

2. The anchor of claim 1, wherein the fastening equipment comprises at least one internal duct through which the hardenable substance can be introduced into the recess of the anchoring part from outside and that is formed in the pivoting part or the anchoring part.

3. The anchor of claim 1, wherein the recess comprises a neck, and wherein the neck includes at least one opening through which an end of the pin can be inserted.

4. The anchor of claim 1, wherein the pivoting part comprises a pretensioning mechanism configured to cause the end of the pin to press against the wall of the recess when the pivoting part has been fitted to the anchoring part.

5. The anchor of claim 1, wherein the end of the pin is slotted.

6. The anchor of claim 1, further comprising at least one ventilation duct, wherein the at least one ventilation duct leads into the recess and wherein the at least one ventilation duct is formed in the pivoting part.

7. The anchor of claim 1, wherein the fastening equipment comprises a substance, wherein the substance is located in the recess of the anchoring part, and wherein the substance can be activated to form the hardenable substance.

8. The anchor of claim 1, wherein, in order to form a pivot joint between the anchoring part and the pivoting part,

an upper side of the anchoring part comprises a first spherical face, the recess is delimited by a second spherical face, the underside of the pivoting part comprises a first spherical counter-face, and the pin comprises at least a second spherical counter-face, and wherein

when the pivoting part has been fitted to the anchoring part, the first counter-face is in contact with the first face and the second counter-face is in contact with the second face.

9. The anchor of claim 1 further comprising a female part used for the releasable securing of the tooth replacement to the pivoting part, wherein the female part and the pivoting part can be connected by means of a snap connection.

11. The anchor of claim 1, wherein the end of the pin comprises two wings.

12. The anchor of claim 1 further comprising a female part used for the releasable securing of the tooth replacement to the pivoting part, wherein the female part comprises an insert of plastic material or metal.

10. An auxiliary instrument for mounting an anchor configured to secure a tooth replacement, wherein the anchor includes an anchoring part, fastening equipment and a pivoting part, the auxiliary instrument comprising:

an introduction head,

wherein the introduction head comprises;

an introduction duct,

wherein the introduction duct can be placed on the pivoting part in order to introduce a hardenable substance through the introduction duct into a recess of the anchoring part.

13. An auxiliary instrument for mounting an anchor configured to secure a tooth replacement, wherein the anchor includes an anchoring part, and a pivoting part, the auxiliary instrument comprising:

a head configured to be placed on the pivoting part of the anchor, and

a straight end for determining the pivoting position of the pivoting part.

14. The auxiliary instrument of claim 13, wherein the length of the end is greater than 5 mm.
