An abutment system, comprising:
- an abutment screw;
- a soft tissue level abutment part adapted to be attached to a bone level dental implant by the abutment screw;
- and
- a further screw adapted to attach a component to a coronal portion of the soft tissue level abutment part,
- wherein the abutment screw has an apical externally threaded portion configured to engage the bone level dental implant and a coronally internally threaded portion,
- wherein the soft tissue level abutment part comprises a soft tissue collar having a coronal flat circumferential platform, the coronal flat circumferential platform having an inner perimeter accommodating at least one indexing element configured to prevent rotation of the component attached to the coronal portion of the soft tissue level abutment part, and
- wherein the further screw has an apical externally threaded portion configured to engage with the coronally internally threaded portion of the abutment screw such that the apical externally threaded portion of the further screw sits at least partially within the soft tissue level abutment part.
