A dental abutment for retrofit use to allow for repair of different types of existing root form implants after traumatic events, reduces or eliminates the need for further surgery. The abutment comprises a threaded spindle having an integrated taper, a plurality of segments secured around the axis of the spindle, and a tapered nut threaded on a distal end of the spindle. The threaded engagement of the tapered nut radially displaces the segments against the root form, fixing the abutment thereto.
