Abstract
The present invention relates to photopolymerizable resin compositions suitable for producing durable dental prosthetic and restorative articles. In particular, the invention relates to photopolymerizable resin compositions comprised of a specific combination of multiple polymerizable components, one or more resin-modifying particle components, and one or more photopolymerization initiator components. Compositions of the invention are especially well-suited to producing durable, stain-and wear-resistant dental prosthetic and restorative articles, such as artificial teeth, crowns, bridges, inlays, onlays, and veneers, in an efficient and reliable manner using additive manufacturing systems and methods (e.g., three-dimensional (3D) printing).
