Abstract

This paper presents the experimental results on influence of nanoparticle size on the mechanical performance of dental nano-composites that comprised of a common dental acrylic resin matrix and different sized treated Titania nanoparticles. The experimental dental nano-composite as manufactured by incorporating treated Titania nanoparticles of size 100 nm as fillers into a common acrylic resin matrix (UDMA). To improve the dispersion ability, the Titania nanoparticles were treated before mixing via high-energy ball milling procedure. The nano-composite properties such as wear rate, modulus of rupture and surface hardness were measured and evaluated. The stability of nanoparticles in the solution was enhanced by adding three (3, 12 and 48 wt%) concentration of silane (A 174), i.e. 3-methacryloxypropyltrimithoxysilane. Dental nano-composite with 3 wt% shown better wear resistance, modulus of rupture and surface hardness as compared to other samples.
