Color stability, surface, and physicochemical properties of three-dimensional printed denture base resin reinforced with different nanofillers.

Various materials have been introduced for the three-dimensional (3D) printing of dentures. In this study, the color stability and surface and physicochemical properties of 3D-printed denture base resins with four types of nanofiller particles were evaluated. AlO, ZnO, CeZr, and SiO nanofillers were added to a 3D printable denture base-resin matrix and subjected to digital light processing.
