Abstract

What is described is a dental light-curable composition for elective production of a visible restoration in the anterior region or for filling of a cavity in the posterior region, comprising a total amount (A) of free-radically polymerizable monomers, where this total amount (A) consists of one, two, three or more than three free-radically polymerizable monomers and has a refractive index nin the range from 1.470 to 1.560, a total amount (B1) of nonaggregated and nonagglomerated inorganic filler particles having a particle size in the range from 7 to 70 nm, where this total amount (B1) has a refractive index nin the range from 1.460 to 1.570 and where this total amount (B1) is in the range from 10 to 30 percent by volume, based on the overall dental light-curable composition, a total amount (B2) of inorganic filler particles having a particle size in the range from 0.12 μm to 10 μm, where this total amount (B2) has a refractive index nin the range from 1.450 to 1.560, and a total amount (C) of photoinitiators.
