| چکیده | ||
| Improving the quality of biomaterials and increasing their durability has always been one of the significant concerns in biomechanical studies. The use of nano-polymers may enhance the properties of implants and biomaterials. The purpose of this paper is to evaluate the influences of adding a different percentage of $Sio_2$ nanoparticles on wear resistance refinement. To measure the impacts of $ SiO_2$ nanoparticles on wear resistance, reinforced PMMA and UHWPE with Nano $SiO_2$ powders were produced. The effect of 0%,3%, and 5% Mass fraction of $SiO_2$ fillers on the wear rate of UHWPE as the artificial joint and 0%,3%, 5%, and 7% fraction of $SiO_2$ fillers on the wear rate of PMMA denture base, experimented by wear machine Tuber GT-7012-T according to ASTM 99g 2017. The experimental results demonstrate that at 5% mf of Nanoparticles, the wear rate reduces up to 40%. However, increasing the mf of Nanoparticles is improper and decreases the wear resistance. One-way ANOVA analysis was applied to determine significant differences between data. | ||
