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.

Polymeric dispersants are disclosed that include an acrylic backbone at least one pendantly attached imide group, wherein the carbonyl of the imide are chemically bonded to a fused aromatic ring. The aromatic ring can be substituted with various electron withdrawing or releasing groups. Desirably dispersant also includes solvent-solubilising chains of polyether, polyester, polyacrylate, and or polyolefin.
