Abstract: The present invention is directed to a process for producing a sintered lithium disilicate glass ceramic dental restoration out of a porous 3-dim article, the process comprising the step of sintering the porous 3-dim article having the shape of a dental restoration with an outer and inner surface to obtain a sintered lithium disilicate ceramic dental restoration, the sintered lithium disilicate glass ceramic dental restoration comprising Si oxide calculated as SiO2 from 55 to 80 wt.-%, Li oxide calculated as Li2O from 7 to 16 wt.-%, Al oxide calculated as Al2O3 from 1 to 5 wt.-%, and P oxide calculated as P2O5 from 1 to 5 wt.-%, wt.-% with respect to the weight of the dental restoration, the sintering being done under reduced atmospheric pressure conditions, the reduced atmospheric pressure conditions being applied at a temperature above 600° C. The present invention is also directed to a kit of parts comprising a porous 3-dim article having the shape of a dental milling block and a respective instruction of use.

Abstract: 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.
