Abstract (en)

[origin: WO2019068611A2] The invention relates to a polymerizable dental composite material which comprises (i) 70 to 85 wt.% of at least one inorganic filler component comprising at least one dental glass and optionally at least one amorphous metal oxide, (ii) 10 to 30 wt.% of a mixture of at least two different urethane (meth)acrylates, (iii) 0.01 to 5 wt.% of at least one di-, tri-, tetra- or multi-functional monomer different from urethane (meth)acrylate, and (iv) 0.01 to 10 wt.% of at least one initiator, initiator system and optionally at least one stabilizer and optionally at least one pigment, the total composition of the composite material adding up to 100 wt.%. The invention also relates to 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 the production of indirect dental prostheses.
