摘要：
The invention relates to a dental composition comprising filler (F1) comprising aggregated nano-sized particles in an amount of from about 30 to about 70 wt. %, filler (F2) comprising agglomerated nano-sized particles in an amount from about 1 to about 20 wt. %, hardenable component (A1) being an urethane(meth)acrylate with a functionality of at least 2 and having a molecular weight from about 400 to about 3,000 g/mol,-hardenable component (A2) being a radically polymerizable (meth)acrylate with a functionality of at least 2 being different from component (A1), redox curing initiator system, the dental composition not comprising non-agglomerated nano-sized filler in an amount above about 10 wt. %, wt. % with respect to the weight of the whole composition. The dental composition is in particular useful as or for production of permanent crown and bridges, inlays, onlays and veneers.
