Antimicrobial polymer composite materials are disclosed that are suitable for making oral devices used in dental applications, such as denture bases. Acrylic resin composite materials comprising antimicrobial polymers and antimicrobial fillers provide reduction in common oral microorganisms after long-term aging, with reduced release rate of antimicrobial agents from the composite material. Antimicrobial polymers are prepared from compositions comprising acrylate and/or methacrylate monomers and polymerizable quaternary ammonium silicon-containing compounds.

The present disclosure relates to a plasma treatment apparatus and a method using the same, and more particularly, to a plasma treatment apparatus for applying, to a target object, such as a biomaterial, characteristics (e.g., removal of organic materials, crosslinking reaction, etching reaction, structural change by surface chemical reaction, sterilization effect, wettability, adhesiveness, bondability, color compatibility, surface reinforcement, modification of surface heat resistance, sterilization, removal of harmful proteins/bacteria, etc.) according to plasma treatment, and a method using the plasma treatment apparatus.

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 swivel shell surrounds the ball and may be fixed in position with 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 lock screw remains accessible through an aperture in the coping when the prosthesis is positioned on the implant abutments. Different embodiments are disclosed for capturing the swivel shell on the ball. Methods for improving passive alignment of the prosthesis to the implants are described.
