Abstract

The invention relates to a hardenable dental resin composition provided as a kit of parts comprising a powder part and a liquid part, the powder part comprising acid-reactive glass filler A, non acid-reactive nanocluster filler B, the liquid part comprising polymerizable components with an acidic moiety, polymerizable components without an acidic moiety, the hardenable dental composition further comprising a dual-cure initiator system the components of which being distributed between the powder part and the liquid part, wherein the dual-cure initiator system comprises sensitizing agent(s), oxidizing component(s), (thio)barbituric acid component(s) and transition metal component(s). The composition can be used as a self-adhesive dental resin filling material, self-adhesive dental resin core build up material, self-adhesive dental resin cement material, self-adhesive fissure sealing material, a self-adhesive dental root channel material.
