    • The present application discloses a dental filling material comprising fillers and a polymerizable resin base, the fillers comprising metastable zirconia particles in the tetragonal and/or cubic crystalline phase with less than 30 % (v/v) in the monoclinic phase, and having surface functionalities of the formula: -Zr-O-Zr-O-C(=O)-X-C(R1)(R2)(R3), wherein X = -O-, -NH-, -S-; R1 / R2 = hydrogen, opt.subst. C1-30-alkyl, a (meth)acrylate moiety moiety, a (meth)acrylate-C1-12-alkyl moiety, opt.subst. C2-30-alkenyl, opt.subst. C5-30-alkadienyl, opt.subst. C8-30-alkatrienyl, or when X = -NH-, R1 / R2 = =O; R3 = hydrogen, C1-6-alkyl, hydroxy, halogen. A method of controlling the volumetric shrinkage of a dental filling material upon curing, and the dental filling material for use in medicine, in particular in dentistry, are also disclosed.
