An abutment (60) for securing a dental prosthesis to an implant fixture (10) is disclosed. The abutment (60) includes a base (62) and an attachable coping (64). The attachable coping (64) carries the dental prosthesis and is mounted on the base (62) of the abutment using a ball-and-socket joint, which permits the dental prosthesis to be easily and accurately aligned with adjacent teeth, implant fixtures or other prostheses. A connector (130) inserted through an aperture in the base (62) of the abutment secures the abutment (60) and the prosthesis to the implant fixture (10).
