Abstract

The invention relates to a curable dental composition comprising a cationically hardenable compound (A) comprising at least two aziridine moieties, a starter (B) being suitable to cure the hardenable compound (A), polymeric particles as filler component (C), the polymeric particles having a maximum particle size of 150 μm or below and the component(s) the polymeric particles are made of being based on fluoropolymers comprising more than 99% monomer repeating units of tetra fluoro ethylene. The invention also relates to the use of such composition for producing a dental impression material or a dental retraction material.
