Multi-unit abutments aligning dental implants and a prosthesis with copings have a base for implant attachment with a ball and swivel shell at least partially surrounding the ball. The swivel shell is preferentially inelastically deformed to make contact at or above and below the equator of the ball. The forming process restricts motion to swiveling action when a predetermined torque threshold is exceeded. A tool passing through the lock screw may drive the post of the base into the implant with the multi-unit assembly in a linear configuration. The swivel shell is then positioned and fixed at desired tilt and azimuthal angles. In some embodiments, a lock screw remains accessible through an aperture in the prosthesis when positioned on the implant abutment. Copings may be attached with screws or snap-on features. Methods for improving passive alignment of the prosthesis and implants are described.
