The photopolymerizable cyanoacrylate-POSS nanocomposite adhesives are promising bio adhesives for dental and bio medicals applications. cyanoacrylate have been used as amatrix phase in dental resin composites and many bioengineering applications due to several advantages such asgood adherent to hard and soft tissues. polyhedral oligomeric silsesquioxane (POSS) which is used as a cross linking agent; affects some mechanical properties of cyanoacrylate bio adhesives[1, 2]. The aim of this study was to investigate the effect of the Acrylo-POSS nanostructure on themechanical properties of a photopolymerizaible cyanoacrylate bioadhesive.
