Abstract
The impact of varying concentrations (0.5%, 1% and 5%) of titanium dioxide (TiO(2)) nanoparticles on the tensile and impact strength of heat-cured, reinforced, colour-modified acrylic resin. The data showed that TiO(2) nanoparticles significantly enhanced the mechanical properties of the material, with 1 wt% TiO(2) providing the highest tensile strength and 5 wt% TiO(2) showing the highest impact strength. Thus, we show that TiO(2) nanoparticles are promising for improving the durability of acrylic resins in denture applications. However, nanoparticle agglomeration at higher concentrations may reduce mechanical performance, warranting further research on dispersion methods.
