description The invention relates to A curable composition for producing dental composite crowns, the composition comprising a resin matrix comprising polymerizable (meth)acrylate(s) not comprising a urethane moiety, polymerizable urethane(meth)acrylate(s), wherein the polymerizable (meth)acrylate(s) not comprising an urethane moiety are used in excess over the polymerizable urethane(meth)acrylate(s), a filler matrix comprising nanocluster(s), fumed silica in an amount below 8 wt. % with respect to the weight of the whole composition, an initiator system comprising photoinitiator(s), organic dye(s), the curable composition not comprising softener in an amount of more than 5 wt. % with respect to the weight of the whole composition, the curable composition having a viscosity below 150 Pa*s at 23° C. and a shear rate of 1 s−1.The invention also relates to a cured article obtained by radiation curing this curable composition by use of an additive-manufacturing method.
