A plug-in connection for releasably mounting a prosthesis or the like on the fixing head of a dowel crown post (10) or the like, having a plug part which is provided on the fixing head and has a circumferential constriction (12) in a plane lying substantially perpendicular to the longitudinal axis of symmetry of the fixing head, a base part (17) which carries the prosthesis, and a resilient clamping ring (20) engaging behind the constriction of the plug part and producing a positive connection between the latter and the base part, the base part being resiliently mounted in relation to the plug part in respect of impact stresses occurring substantially in the direction of the longitudinal axis of symmetry of the fixing head. The plug part has a cylindrical under-part (12) adjoining the dowel crown post and a mushroom-shaped upper part (14) adjacent thereto whose external diameter is largest close to the end of the under-part which is remote from the dowel crown post, where it exceeds the external diameter of the under-part and its generated surface extends substantially conically from the region of maximum diameter to a flattened point (16) of the upper part; the base part has in the region of the constriction an annular recess (18) which partially receives the resilient clamping ring (20); and a mounting ring (22) of resilient plastic and/or rubber material is arranged between the conical generated surface of the upper part and the base part. |
