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.
Claims12
A method of making an intraoral device that reduces bacterial growth and biofilm formation, comprising:
- a. providing a mixture of resin components comprising
- i. a plurality of polymerizable (meth)acrylate monomers;
- and
- ii. antimicrobial particles;
- and
- iii. an initiator;
- b. forming the mixture into the dimensions of the intraoral device using a three-dimensional printing method;
- and
- c. light curing the mixture using the three-dimensional printing method to obtain the intraoral device.
