Abstract The main purpose of the present study is evaluate and compare the effect of aging on PMMA reinforced by 5wt.% nano-ZrO2 and 5wt.% AgNPs regading to flexural strength ,surface hardness and surface roughness. Also, forty five specimens were prepared for physicomechnical study. bars shaped specimens for flexural. The surface roughness and hardness were performed on the same specimens used for flexural strength. |
