Novel dental restorative materials having low polymerization shrinkage stress via stress relaxation by addition-fragmentation chain transfer

Nov 28, 2017 by in Dental Materials Comments Off on Novel dental restorative materials having low polymerization shrinkage stress via stress relaxation by addition-fragmentation chain transfer

Abstract Objectives To produce a reduced stress dental restorative material while simultaneously maintaining excellent mechanical properties, we have incorporated an allyl sulfide functional group into norbornene–methacrylate comonomer resins. We hypothesize…
