Abstract
The invention concerns a photopolymerizable composition comprising: at least one epoxyvinylester resin, at least one urethane acrylate resin, at least one organic silicon-free particulate filler having an average particle size less than 10 μm and a specific surface more than 10 m2/g, at least one photoinidator. Said composition is in particular useful for making dental prosthesis preforms and models.
