High strength three dimensional fabricating material systems and methods for producing dental products

Abstract:

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.
