Abstract: The invention relates to a polymerizable material for the production of a dental material for building up stumps, having the following characteristics: —the material comprises at least one polymerizable monomer, oligomer, and/or pre-polymer, —the total filler content of the material is 50 to 85% by weight, —the material comprises 5 to 25% by weight nano-filler, having a mean particle size d5o of 300 nm or less, wherein at least 50% by weight of said nano-filler has a particle size of 200 nm or less, —the material comprises 35 to 75% by weight micro-filler, having a mean particle size d50 of 0.3 to 10 ?m, —the ability to grind the cured material for building up stumps deviates from the ability to grind human dentin by 15% at the most. The invention further relates to a kit comprising at least two components for the production of such a polymerizable material.

Abstract: The invention relates to a filled polymerisable dental material comprising, in an organic binding agent, a partially aggregated nanometric filler and another inorganic and/or organic filler. The invention has the advantages of nanometric fillers in dental materials, based on economical aggregated fillers such as silicon dioxide obtained by pyrolysis.
