Abstract

The effect of anatase TiO₂ nanoparticles on the flexural strength of PMMA resins, comparing conventional and injection molding techniques is of interest. A total of 120 acrylic specimens were prepared and divided into control, 0.5% TiO₂, and 1% TiO₂ groups. Flexural strength was measured using a three-point bend test and analyzed with ANOVA. The injection molded group showed superior flexural strength compared to the compression molded group, with control specimens exhibiting the highest values. Increasing TiO₂ concentration led to a significant reduction in flexural strength, indicating a negative correlation between nanoparticle content and mechanical performance.
