Description

[0037] Further details, advantages and features of the present invention will be apparent from the following description of embodiments based on the drawing. Shown in:

[0038] FIG. 1 is a schematic, highly simplified schematic illustration of a possible embodiment of an anchoring device according to the invention,

[0039] FIG. 2 is an embodiment of the anchoring device according to the invention without a female anchoring part arranged on a male anchoring part, and

[0040] FIG. 3 is an illustration corresponding to FIG. 2 with mounted female anchoring part.

[0041] The general structure of an anchoring device 1 according to the invention, which is also referred to as an attachment system in dental terminology, can be seen from the schematic illustration in FIG. 1.

[0042] The anchoring device 1 is suitable for implant-supported, removable dental prostheses and for this purpose has a female anchoring part 2, which is arranged on the outside of a male anchoring part 3 and is plugged on, so that the female anchoring part 2 can advantageously be detached from the support of the dental prosthesis.

[0043] Furthermore, the anchoring device 1 has a base 4, which is provided with a connection geometry arrangement 4A, which is followed by an implant thread 4B, which is preferably integrally connected to the connection geometry arrangement 4A. Thus, the implant thread 4B serves to fix the anchoring device 1 in the implant.

[0044] According to the invention, the anchoring device 1 further comprises an elastic connection element 5, which is in particular wire-shaped with a diameter D and which elastically connects the male anchoring part 3 to the base 4, in particular to the connection geometry arrangement 4A of the base 4.

[0045] FIG. 2 shows a concretely realized anchoring device 1 with the components previously explained with reference to FIG. 1, so that in FIG. 2 all components corresponding to those of the schematic illustration of FIG. 1 are marked with the same reference numbers.

[0046] In particular, it is clear from FIG. 2 that the elastic connection element 5, which may be formed in particular from a shape memory alloy, for example nickel-titanium, has a diameter that is significantly smaller than the diameters of the male part 3 and the base 4, in particular the connection geometry arrangement 4A.

[0047] Furthermore, FIG. 2 shows an implant 6 connected to implant thread 4B (not visible in FIG. 2).

[0048] FIG. 3 illustrates the anchoring device 1 according to FIG. 2, with the female anchoring part 2 arranged on the male anchoring part 3.

[0049] In the embodiment according to FIGS. 1 and 2, the female anchoring part 2 and the male anchoring part 3 are each formed as a cone telescope, while the female anchoring part 2 of the schematic illustration of FIG. 1 is formed as a cylinder secondary telescope, which also applies to the male anchoring part 3 of the embodiment according to FIG. 1.

[0050] In addition to the foregoing written disclosure, explicit reference is hereby made to the graphic illustration in FIGS. 1 to 3 to supplement the disclosure.
