Dental composite material with a balanced ratio of flexural strength and modulus of elasticity and milling blanks of this composite material

摘要

The invention relates to a polymerizable, dental composite material comprising (i) 60 to 85% by weight of at least one inorganic filler component comprising at least one framework silicate and optionally at least one dental glass and / or at least one amorphous metal oxide, (ii) 10 to 40% by weight. % of a mixture of at least two different urethane (meth) acrylates, (iii) from 0.01 to 5% by weight of at least one di, tri, tetra or multifunctional monomer which is not a urethane (meth) acrylate, ( iv) 0.01 to 10 wt .-% of at least one initiator, an initiator system and optionally at least one stabilizer and optionally at least one pigment, wherein the total composition of the composite material is 100 wt .-% and a polymerized composite material having a flexural strength greater than or equal to 240 MPa and a modulus of elasticity of 16 to 20 GPa for the production of indirect dentures.
