摘要： A polymerisable 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 at least one monomer comprising 1,3-bis(5′-alkyl-3′,8′-dioxo-2′-aza-4′,7′-dioxa-decyl-9′-en)phenyl and/or 1,3-bis(5′,9′-dialkyl-3′,8′-dioxo-2′-aza-4′,7′-dioxa-decyl-9′-en)phenyl, (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 and 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, and a polymerized composite material having a flexural strength of greater than or equal to 190 MPa and an elastic modulus of 12 to 21 GPa for the production of indirect dentures.

摘要： A polymerisable dental composite material comprising (i) 60 to 85% by weight of an 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% 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, an initiator system and optionally at least one stabiliser and optionally at least one pigment, wherein the total composition of the composite material amounts to 100% by weight, and a polymerised composite material having a flexural strength of greater than or equal to 240 MPa and an elastic modulus of 16 to 20 GPa for the production of indirect dentures.
