Light-curing composition for the production of dental components with matt surfaces

A method for producing a light-curing composition for the production of dental components in a digital light processing (DLP) method or a stereolithography (SLA) method, comprising the steps of:

• A) producing or providing a liquid monomer composition comprising one or more radically polymerizable monomers,
• B) producing or providing solid polymer agglomerates comprising agglomerated solid polymer particles with a particle diameter in the range from 0.4 to 4 μm,
• C) mixing the components produced or provided in steps A and B in order to obtain a basic mixture, comprising on the basis of the total mass of the basic mixture:
• the liquid monomer composition with a mass fraction of 60% or more, and
• the solid polymer agglomerates with a combined mass fraction of 0.1 to 30%,
• E) mechanically treating the basic mixture to break down the solid polymer agglomerates and to disperse the polymer particles in the liquid monomer composition.
