Abstract

Nanomaterials have unique physical and mechanical characteristics. The addition of nanoparticles advances the mechanical performance of polymers, because the ratio of surface area-to-volume is high. Nanoparticles are utilised to produce materials with different behaviour because of interfacial reactions. The current review compiles and discusses the available literature on the positive impact of nanoparticles on the mechanical behaviour of resin-based dental composites, in addition to the recent advancements. The effects of different types of fillers in nano-ranged size have been studied. It also presents appropriate filler quantity for the enhancement of some mechanical properties. Finally, the important role of energy dissipation mechanisms in dental composites has been emphasised. 

Keywords: Dental composites, nanoparticles, nanocomposites, mechanical properties, energy dissipation mechanisms
