Background: To investigate the effect of zirconium dioxide nanoparticles (ZrONPs) on the shear bond strength (SBS) of hard denture lines bonded to different denture base resins.
Methods: Five different denture bases were used in this study: conventional heat-cured resin, IvoCad, AvaDent, NextDent, and FormLabs, in acrylic specimens of 10 × 10 × 2.5 mm (N = 150, n = 10).
