3d-printable antimicrobial composite resins, methods for manufacturing the same

The invention relates to the fields of microbiology, dentistry and the manufacture of antibacterial products, more in particular to printable polymerizable composite resins that have antimicrobial properties. Provided is a photocurable antibacterial resin composition, comprising (i) a polymer matrix comprising at least one biocompatible polymerizable acrylic compound; (ii) a photoinitiator system; and (iii) a methacrylate-modified positively charged compound (PCC) having antibacterial properties, wherein the PCC is present in the composition as polymeric PCC (p PCC) obtained by polymerization of methacrylate-modified PCC monomers.
