Abstract
The purpose of this paper is to study the effect of methacrylated polyhedralsilsesquioxanes (POSS) on the fracture toughness of poly(methyl methacrylate) (PMMA) based denture‐based resins. POSS is a nanostructured material, that is, known to reinforce polymeric systems. Previous work has shown that POSS can improve the mechanical properties of dimethacrylate dental resin systems. Our work shows that there is no significant improvement and a significant drop in mechanical properties is accompanied by evidence of crystallization in the PMMA.
