Abstract
According to one aspect of the present invention, a dental filling material is manufactured by surface-treating an inorganic filling material with a silane coupling agent having an epoxy group and then by causing a ring-opening reaction with a composition containing an epoxide having a (meth)acryloyl group.
Claims7
A dental filling material that is manufactured by surface-treating an inorganic filling material with a silane coupling agent having an epoxy group and then by causing a ring-opening reaction with a composition containing a ring-opening reaction initiator and containing an epoxide having a (meth)acryloyl group, wherein the ring-opening reaction initiator includes at least one of N,N-diethyl-1,3-diaminopropane, 2,2′-diaminodiethylamine, bis(4-aminophenyl)sulfone or phthalic anhydride.
A dental filling material that is manufactured by causing a silane coupling agent having an epoxy group, a composition containing a ring-opening reaction initiator and containing an epoxide having a (meth)acryloyl group, and an inorganic filling material to react, wherein the ring-opening reaction initiator includes at least one of N,N-diethyl-1,3-diaminopropane, 2,2′-diaminodiethylamine, bis(4-aminophenyl)sulfone or phthalic anhydride.
