The aim of this study was to prepare materials that use to manufacture a denture by using a composite material, also studying their properties. Poly methyl methacrylate (PMMA) resin is widely utilized in dental applications. Two types of additives (Nano zinc oxide and Nano zirconium oxide) with different weight percentages (1%, 2%, 3%, 4% and 5%) were added to PMMA resin to improve its properties. The mixture was chosen experimentally to obtain the optimum properties also to avoid cracks formation. The ratio of PMMA and dichloromethane were (20% wt) and (80% wt) respectively for pure specimens. The result showed that there was an increasing in thermal conductivity, completion strength and a decreasing in roughness.
