Abstract:
1. A hardenable dental composition comprising component (A) comprising a cationically hardenable compound, wherein component (A) has on average at least 2 aziridino groups or more and a molecular weight of at least about 500, component (B) comprising an initiator being able to initiate the hardening reaction of the cationically hardenable compound, and component (C) comprising a filler, wherein the filler comprises a filler body and a filler surface, the filler surface comprising side groups with polar moieties, the polar moieties being attached to the filler surface by a silane coupling agent being characterized by the following formula wherein A represents a polar moiety, B represents a spacer group, R R with m=1, 2, 3 or 4 and n=0, 1 or 2; wherein the polar moieties are selected from thioles, phosphines, amines, amide, urethanes, thiiranes and combinations thereof; and wherein the hardenable dental composition is characterized by the following parameter after hardening: Tensile Strength (according to DIN 53504): at least about 3.2 MPa.
