<p>The invention relates to a dental prosthesis, comprising an implant body (1) and an abutment (2) that can be inserted into a receptacle of the implant body (1), said abutment (2) forming a passage opening (4) for accommodating a cap screw (3) that engages in an internal thread (5) of the implant body (1), which screw is supported by means of a conical cap part (7) of the cap screw (3) on a conical shoulder (8) of the abutment (2). In order to provide advantageous constructional conditions it is proposed that the conical cap part (7) has at least two consecutive conical sections (9, 10) in the axial direction, which conical sections have an opening angle that differs from the opening angle of the conical shoulder (8), and when the one conical section (9) contacts the conical shoulder (8) without pressure the other conical section (10) engages in the shoulder cone (11) with play.</p> |
