Photopolymerizable composition based on an epoxyvinylester resin and on a urethane acrylate resin and use thereof for making dental prosthesis preforms and or models

摘要

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.
