Thermoactive dental composite composition

A dental, light-curable, one-component composite composition, comprising:

• (A) monomers,
• (B) fillers, and
• (C) initiators,
• wherein:
• the viscosity η20 of the composite composition at 20° C. is greater than 400 Pa*s
• and
• the viscosity η50 of the composite composition at 50° C. is less than 150 Pa*s
• and
• the quotient η50/η20 of the viscosity of the composite composition at 50° C. and the viscosity of the composite composition at 20° C. is less than 0.125,
• wherein
• the fillers (B) are producible by mixing filler constituents
• (B1) 2% to 25% by weight of inorganic filler having a D50 of 1 nm to 200 nm,
• (B2) 40% to 90% by weight of inorganic filler having a D50 of greater than 1 μm to 10 μm,
• (B3) 8% to 50% by weight of inorganic filler in a size having a D50 of 0.4 μm to 1.0 μm, and
• (B4) 0% to 25% by weight of further fillers that cannot be assigned to (B1), (B2) or (B3),
• wherein the percentages by weight of (B1), (B2), (B3) and (B4) are based on the total mass of the fillers (B), and
• wherein components (B1) and/or (B2) and/or (B3) and/or (B4) have been silanized with a compound of the formula (1) or (2)
• wherein R1 denotes a C1- to C4-alkyl group, and
• R2 denotes a C1- to C8-alkyl group, and
• R3 denotes a hydrogen atom or a methyl group, and
• a=1, 2 or 3, and
• b=3−a, and
• n=1 to 8, and
• m=1 to 8.
