A dental implant connection arrangement, comprising:
- a screw,
- an abutment provided with a first coronal opening and a second apical opening, the first coronal opening being sized to allow insertion of the screw through the first coronal opening into the interior of the abutment, and
- a circular ring, wherein the ring retains the screw inserted in the abutment,
- wherein the ring is fixed fully within the first coronal opening of the abutment after insertion of the screw, at a location coronally above and remote from the screw with a non-positive or a positive fit or a material joint, such that a cavity is formed in the interior of the abutment, which allows play of the screw prior to attachment to a dental implant.
