A dental implant abutment arrangement for use with a dental implant has an abutment with a proximal retaining member and an axial bore. The retaining member is rotationally asymmetrical and has a transverse area that is large enough to resist rotation and axial motion of the abutment in a dental impression material. The axial bore has a tapered distal bore portion with an inner taper for matching an outer taper of an abutment receiving portion of an implant. An insertion tool is provided for pulling the abutment toward the implant to removably lock the inner taper to the matching the outer taper and a removal tool is provided for pushing the abutment away from the implant to disengage the lock between the inner taper and the outer taper.
