Abstract
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.
