The (PMMA-Ag) nano-composites films were prepared via photo polymerization method with different percentages (0.0%, 0.05%, 0.1%, 0.15% and 0.2%) of Ag. The structural, bacterial and mechanical properties of nano-composites were studied, FTIR spectra show a shift in peak position as well as a change in intensity. Scanning electron microscopy shows the surface morphology of the (PMM-Ag) nano-composites films. Three point bending testing, compressive strength, and impact strength were investigated and the results illustrate each mechanical property which improves the polymer characteristics. Then we reached that nano-composite materials are considered as the most important materials which are used as dental molds.
