More Information
Summary:An improved dental material based on a polymerisable, ethylenically unsaturated monomer as binder and on a catalyst for cold, hot and/or photopolymerisation contains as inorganic filler 20 to 90% by weight of a mixture of (A) amorphous spherical particles of silicon dioxide and up to 20 mol% of an oxide of at least one element of groups I, II, III and IV of the periodic table with a refractive index of 1.50 to 1.58 and with an average primary particle size of 0.1 to 1.0 mu m, and (B) quartz, glass ceramic or glass powder or mixtures thereof with a refractive index of 1.50 to 1.58 and with an average primary particle size of 0.5 to 5.0 mu m and, where appropriate, small amounts of other fillers to increase the opacity and adjust the viscosity.
