Arginine-loaded mesoporous silica nanoparticles modified 3D-printed nanocomposite denture base resin with improved mechanical and antimicrobial properties

The addition of 1.0 wt% Arg@MSNs imparted synergistic enhancements in antimicrobial efficacy and mechanical properties to the 3D-printed nanocomposite, while maintaining clinically acceptable surface roughness and aesthetic performance. These findings demonstrated that Arg@MSNs modified 3D-printed nanocomposite denture base resin, by combining 3D-printed resin with nanotechnology, has promising potential for functionalized dental prostheses.
