摘要： A polymerizable dental composite material comprising (i) 70 to 85% by weight of an inorganic filler component comprising at least one dental glass and optionally at least one amorphous metal oxide, (ii) 10 to 30% by weight of a mixture of at least two different urethane (meth)acrylates, (iii) 0.01 to 5% by weight of at least one di-, tri-, tetra- or multi-functional monomer not being a urethane (meth)acrylate, (iv) 0.01 to 10% by weight of at least one initiator, of an initiator system as well as optionally of at least one stabilizer and optionally of at least one pigment, wherein the total composition of the composite material amounts to 100% by weight, as well as a polymerized composite material having a flexural strength of greater than or equal to 200 MPa and an elastic modulus of 15 to 20 GPa for producing indirect dentures.
