This invention relates to printable high strength/toughness polymerizable material systems for making dental products such as artificial teeth, dentures, splints, veneers, inlays, onlays, orthodontic appliances, aligners, copings, frame patterns, crowns and bridges and the like. A DLP, stereolithography, modified or their modification and combination based printer is used to cure polymerizable material in several different methods of this invention to build-up the object. The resulting three-dimensional object has good dimensional stability.

The present invention is related to a dental composition comprising at least one polymerizable monomer having at least one ethylenically unsaturated group; and a radical initiator system comprising a photosensitizer haying an absorption maximum ranging from 400 nm to 800 nm; and at least one CH-acidic compound as coinitiator.

The present invention is related to a dental resin modified glass-ionomer composition comprising (a) water; (b) at least one polycarboxylic acid; (c) at least one compound having at least one phosphorous atom; and (d) at least one bisacrylamide having formula (I). The present invention is further related to a kit comprising such a dental resin modified glass-ionomer composition.
