Described herein are thermoplastic denture frames having significantly improved lifetimes as well as comfort. The denture frames include a polymer composition including at least one poly(ether ether ketone) (PEEK) polymer and at least one polyphenylsulfone (PPSU) polymer. It was surprisingly discovered that the polymer compositions have significantly improved color stability, relative to corresponding polymer compositions including PEEK polymer as the only polymeric component of the polymer composition. Additionally, the polymer compositions have significantly improved toughness, flexibility and dimensional stability. The combination of the aesthetic characteristics and mechanical characteristics of the polymer compositions allows for denture frames having improved lifetimes and comfort.

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).
