摘要： Abutment for a dental implant (50), with an apical end (4) and with a coronal end (6) arranged opposite the apical end in the longitudinal direction. In the area of the apical end (4), the abutment has an insert portion (8) which is designed to be received by an opening of the dental implant and which has an anti-rotation segment (10) with at least one anti-rotation element (27) which is designed to cooperate with a corresponding mating anti-rotation element (53) of the dental implant (50). The anti-rotation element (27) has a groove (18′, 18″) which, from the edge of the anti-rotation segment (10) directed toward the apical end (4), extends in the coronal longitudinal direction along a groove portion (14) with a substantially constant groove width. The groove (18′, 18″) is continuously widened in a transition portion (20) adjoining the groove portion (14), in order to merge into a bevel (24′, 24″) in a bevel portion (22) adjoining the transition portion (20).
