In the present work, mechanical properties of polymethyl methacrylate (PMMA) polymer that is used for denture materials are studied and developed, the study done by preparing composite materials consists of resin matrix material (PMMA) which reinforced by two types of nano fillers (zirconia and silica) in (1%, 2%, and 3%) weight fractions. Some mechanical tests, like (tensile, impact, flexural, and hardness) are included in this work. The results of this work showed that using the reinforcing nanofillers have a good effect on the performance of composite materials that prepared for using as acrylic denture material so that all values of the studied properties increased with increasing of the concentration of nanofillers in these composite materials, except the elongation property, the values of these properties showed the maximum rates at 3 % ratio of nano fillers. Also, all obtained results showed the silica-PMMA composites exhibited higher mechanical properties compared to zirconia-PMMA composites.
