Abstract
Denture bases made of commonly used acrylic polymers have weak mechanical qualities. This investigation sought to determine how adding titanium dioxide nanoparticles (TiO2) to acrylic denture base materials might affect their transverse strength (Poly Methyl Mehta Acrylate PMMA). A controlled group and experimental group of percentages and 2%wt of TiO2 powder was added to monomer and mixed by probe sonication appliance. SEM was performed for the Titanium Dioxide (TiO2) and the composite of (PMMA and TiO2 NPs) that showed diameter of TiO2 NPs (25.7 nm) and good distribution of NPs in PMMA. The outcomes demonstrated progress in the Transverse Strength of Heat Cured Acrylic Resin.
