The aim of this study was to draw a comparison of wear resistance between heat-curing acrylic resin modified with silanized nanoalumina and commercially artificial tooth.Two-body wear of heat-curing acrylic resin modified with silanized nanoalumina 0.25, 0.5, 0.75, 1 wt% and 4 brands of commercially artificial teeth consisted of acrylic resin (Cosmo HXL and Yamahachi New Ace) and composite teeth (Endura and Yamahachi PX) were analyzed, contemplated using pin on disc tribometers stipulated with heat-curing acrylic resin without nanoalumina served as a control group. Volume losses were measured and statistically analyzed by using One-way analysis of variance (ANOVA) with a significance level 95%. Volume loss of acrylic resin modified with silanized nanoalumina 0.25 wt% and Endura composite teeth were the lowest, significantly different from control group and Yamahachi New Ace. In conclusion, property improvement by adding 0.25 wt% silanized nanoalumina can enhance wear resisteance of acrylic resin similar to composite teeth and significantly higher than conventional acrylic resin teeth. No significant difference was observed in wear resistance of 0.5, 0.75, 1 wt% groups, but wear resistance tended to decline when the number of nanoalumina increased.
