DENTAL COMPOSITE MATERIAL WITH ADAPTED RATIO OF FLEXURAL STRENGTH TO ELASTIC MODULUS, AND MILL BLANKS MADE OF SAID COMPOSITE MATERIAL

摘要

The invention relates to a polymerizable dental composite material comprising (i) 60 to 85 wt.% of at least one inorganic filler component comprising at least one tectosilicate and optionally at least one dental glass and/or at least one amorphous metal oxide, (ii) 10 to 40 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 multifunctional monomer which is not urethane(meth)acrylate, and (iv) 0.01 to 10 wt.% of at least one initiator, an initiator system, optionally at least one stabilizer, and optionally at least one pigment, wherein the total composition of the composite material is 100 wt.%. The invention also relates to a polymerized composite material with a flexural strength of more than or equal to 240 MPa and an elastic modulus of 16 to 20 GPa for producing an indirect dental prosthesis.
