This analysis demonstrates how titanium dioxide nanoparticles enhance mechanical properties in acrylic resin, suggesting potential for denture applications.
The impact of varying concentrations (0.5%, 1% and 5%) of titanium dioxide (TiO₂) nanoparticles on the tensile and impact strength of heat-cured, reinforced, colour-modified acrylic resin. The data showed that TiO₂ nanoparticles significantly enhanced the mechanical properties of the material, with 1 wt% TiO₂ providing the highest tensile strength and 5 wt% TiO₂ showing the highest impact strength. Thus, we show that TiO₂ 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.
