To evaluate and compare the tear strength, water absorption, percentage elongation of a maxillofacial silicone elastomer with and without incorporation of nanoparticles. Methods: 30 specimens each of circular, dumbbell and trouser shapes prepared out of maxillofacial silicone MDX- 2- 4210. Out of 30, 10 specimens were control, 10 specimens prepared with silver nanoparticles added to silicone elastomer and other 10 with titanium dioxide nanoparticles added to silicone elastomer. Circular specimens checked for water absorption by measuring the dry and wet weights. Dumbbell specimens measured for tear strength and other trouser shaped specimens checked for percentage elongation using universal testing machine. Conclusion: A marked decrease in water absorption was noticed for silver and titanium dioxide nanoparticle groups. There was an increase in mechanical properties for nanoparticle groups over control group.
