A new class of sophisticated nanocomposites has been made possible by the integration of nanoparticles into three-dimensional (3D) printed denture bases, which brought about improvements in biological and physicomechanical properties. While additive manufacturing technology is a major advancement in prosthodontics, it is still difficult to achieve superior mechanics in 3D-printed denture resins, even though they have good biocompatibility and aesthetics. In order to assess the impact of adding barium titanate nanoparticles (BaTiO3NPs) to 3D-printed acrylic dentures in a weight percentage of (0.5 and 1) on certain mechanical properties, the current study was conducted. A sum of 90 specimens divided into three groups was built up for measurements per individual test. The flexural (bending) strength, surface hardness, impact strength, specimen microstructure, and elemental analysis for BaTiO3NPs were quantified utilizing a three-point bending test, Shore D hardness test machine, Izod's impact tester, field emission scanning electron microscope (FESEM), and energy dispersive spectroscopy (EDX), respectively. The outcomes of the investigation confirmed that, in comparison to unmodified resin, the inclusion of BaTiO3NPs within a 3D-printed resin notably ameliorates its flexural, impact, and surface hardness qualities (P value < 0.05). These results show promise for creating a new denture base made up of 3D-printed nanocomposites with improved material qualities.
