Abstract

See full text

Polymerizable material for producing a dental stump construction material, comprises: at least one polymerizable monomer, an oligomer and/or a prepolymer; 5-25 wt.% of a nano-filler with an average particle size of = 300 nm; and 35-75 wt.% of a microfiller with an average particle size of 0.3-10 mu m, where: at least 50 wt.% of the nano-filler exhibits a particle size of = 200 nm; the total content of the filler is 50-80 wt.%; and the grinding ability of the hardened stump construction material is at most 15% of the grinding ability of human dentin. Independent claims are included for: (1) kit for the preparing the polymerizable material comprising at least two components, which are mixed to obtain the polymerizable material; and (2) dental stump construction material obtained by hardening the polymerizable material.
