The present invention relates to an abutment for a dental implant(50), with an apical end (4) and with a coronal end (6) arranged opposite theapicalend in the longitudinal direction. In the area of the apical end (4), theabutment hasan insert portion (8) which is designed to be received by an opening of thedentalimplant and which has an anti-rotation segment (10) comprising at least oneanti-rotationelement (27). The anti-rotation element (27) comprises a groove (18', 18' ')which, from the edge of the anti-rotation segment (10) directed toward theapicalend (4), extends in the coronal longitudinal direction along a groove portion(14)with a substantially constant groove width. The invention is characterized inthat thegroove (18', 18' ') is continuously widened in a transition portion (20)adjoining thegroove portion (14), in order to merge into a bevel (24', 24'') in a bevelportion (22)adjoining the transition portion (20).
