Abrégé

A multi-unit abutment aligning a dental implant and a screw-attached prosthesis with copings is disclosed. The multi-unit abutment has a threaded base post for attachment to the implant and a ball portion. A one-piece swivel shell surrounds the ball and may be fixed in position without a lock screw. A drive feature on the ball allows a tool passing through the lock screw to drive the base post into the implant with the multi-unit assembly in a linear configuration. The swivel shell is then positioned and fixed at a desired tilt and azimuthal angle. The swivel shell has a mating surface for a coping. The multi-unit abutment can be used for full arch dental prosthesis. The multi-unit abutment can provide passive changes in alignment of the swivel shell relative to the ball in response to native forces or changes, over time.

Abrégé

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.

A mixing and dispensing syringe comprising a plunger, barrel and dispensing cap is disclosed. The barrel and plunger are assembled to form a shallow open container for adding reactive components and manually mixing them with a stirring paddle. The relatively wide-open top of the mixing container is proximate the dispensing end of the syringe. After mixing, the dispenser cap is attached to the open end of the barrel preferably with an interference fit. The barrel diameter is preferably comparable to the barrel length. A stop may be provided to prevent relative movement of the barrel and plunger in one or more directions. Although the syringe is designed for mixing reactive hardening components in the syringe, the ease of filling the syringe through the proximal orifice makes it useful for dispensing other materials.
