    [0032] FIG. 1 is a longitudinal section through an implant;

    [0033] FIG. 2 is a frontal view of an implant;

    [0034] FIG. 3 is a side view of an abutment;

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

    [0037] In FIG. 1, an implant 10 is shown extending along a longitudinal direction L. In its outer area, the implant 10 has an implantation area 24 in the form of a thread. This implantation area 24 is designed to be arranged in a jaw of a patient. In other words, the implant 10 shown in FIG. 1 is therefore a dental implant. The implant-sided arrangement area 12 is arranged internally in the implant 10. This interior implant-sided arrangement area 12 has an implant-sided conical section 14, which has a basic conical configuration. This basic conical configuration of the implant-sided conical section 14 is thereby achieved by the fact that the perfectly conical configuration of the implant-sided conical section 14 is destroyed or broken through by the anti-rotation structures 16 present there. This implant-sided conical section 14 forms an implant-sided cone angle W2 with the longitudinal direction L, in particular as shown in a transition region to the cylindrical section 18. In the implant-sided conical section 14, the anti-rotation structures 16 are present in the form of contact surfaces 22. These contact surfaces 22 have a normal N, which lies in a plane formed by the longitudinal direction L and the radial direction R. The contact surfaces 22 thereby form a first implant-sided taper angle W1 with the longitudinal direction L. In the embodiment shown in FIG. 1, the implant-sided conical section 14 forms a distal end of the implant-sided arrangement area 12 in the direction of the longitudinal direction L. The implant-sided conical section 14 forms the implant-sided arrangement area 12. The implant-sided arrangement area 12 also has a cylindrical section 18, the cylindrical section 18 joining the implant-sided conical section 14 in the longitudinal direction L. In addition, the implant side arrangement area 12 also has a threaded section 20 which joins the cylindrical section 18 in the longitudinal direction L.

    [0038] FIG. 2 shows a frontal view in longitudinal direction L of the implant 10 or of the implant-sided arrangement area 12. The embodiment of the implant 10 shown in FIG. 2 can in principle match the embodiment shown in FIG. 1. The implant-sided arrangement area 12 has a polygon in a plane perpendicular to the longitudinal direction L, which is formed by the contact surfaces 22 or by the implant-sided anti-rotation structures 16. The implant-sided anti-rotation structures 16 are designed to taper in the direction of the longitudinal direction L. The contact surfaces 22 have a normal N, which lies in a plane formed by the longitudinal direction L and the radial direction R.

    [0039] FIG. 3 shows an abutment 50 which is designed as a dental implant abutment. The abutment 50 has an external connection area 52, wherein this connection area 52 is designed to make contact with an implant 10, in particular with an implant-sided arrangement area 12 of an implant 10. The connection area 52 has a body-sided conical section 54, wherein body-sided anti-rotation structures 56 are arranged in the body-sided conical section 54. In the embodiment disclosed, these body-side anti-rotation structures 56 are formed as planar transmission areas 60. Adjacent to the body-sided conical section 54 is a body-sided cylindrical section 58 in the longitudinal extension direction L2. The transmission areas 60 or the anti-rotation structures 56 on the body side are formed tapering in the direction of the longitudinal extension direction L2 and form a second taper angle Wi1 with the longitudinal extension direction L2.

    [0040] FIG. 4 shows a partial sectional view through an abutment 50. A clamping area 62 is arranged inside the abutment 50, which—as shown—can be at least partially conical and serves to clamp the abutment 50 to an implant 10 with the aid of a threaded connecting pin 80.

    [0041] In FIG. 5, a frontal view in the longitudinal extension direction L2 of the abutment 50 is shown. The abutment 50 shown in FIG. 5 can thereby match the embodiment shown in FIG. 3 and/or the embodiment shown in FIG. 4. The structure 50 has a plurality of transmission surfaces 60, each of which has a normal N. This normal N lies in a plane which is spanned by the radial direction R1 and by the longitudinal extension direction L2. As can be seen from FIG. 50, the transmission surfaces 60 form a polygon in the form of a hexagon with one another in a plane which is perpendicular to the longitudinal extension direction L2.
