Despite its fragility, poor thermal properties, and high water sorption rates, polymethyl methacrylate (PMMA) is commonly used in denture fabrication. This study aimed to examine how the addition of Aluminum oxide nanoparticles affected the properties of PMMA. A thermal constant analyzer measured the thermal properties of the Al2O3 nanoparticles using the transient plane source (TPS) method. Results showed that the thermal conductivity and thermal diffusivity of acrylic resin improved ...
