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 (2), said abutment forming a passage opening (5) for accommodating a head screw (4) that engages in a female thread (6) of the implant body (1) and supports a tooth structure (3) secured against twisting. In order to ensure simple constructional conditions it is proposed that the head (7) of the head screw (4) is connected in an interlocking manner to an anti-rotation device (9) which can only be twisted together with the head screw (4) and which is glued together with the tooth structure (3).
