Abstract: Base material arrangements having at least two layers can accommodate the addition of antifungal material (nanofiller), such as in denture base resin without significantly compromising the mechanical properties and/or translucency of the base material arrangements. Antifungal agents such as nanosilver and nanozirconia can be used to modify a surface layer of the material arrangements, such as the denture base, to overcome certain known shortcomings of the modified materials, e.g., typical acrylic resins containing nanosilver and nanozirconia.
