The present application provides dental fillers, and methods of making and using dental fillers that include a treated surface that includes a phosphate salt. Dental compositions including such dental fillers can be useful for delivering ions to the oral environment. Dental compositions, and methods of using dental compositions that include a phosphate salt and a hardenable resin or a water-dispersible, polymeric film former are also provided.

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.

Block for use in a CAD/CAM system for the manufacture of a dental restauration, said block consisting of a thermoplastic polymer comprising PEEK including radiopaque particles selected from the group comprising BaZrO.sub.3, YbF.sub.3, Yb.sub.2O.sub.3, SrO, SrZrO.sub.3, SiO.sub.2ZrO.sub.2, SiO.sub.2Yb.sub.2O.sub.3, Lu.sub.2O.sub.3, LuF.sub.3.

Disclosed is a material for a denture base containing a polymer component and containing an acrylic resin.

Provided herein is a self-etching dental adhesive that exhibits excellent adhesiveness not only to dentin untreated by phosphoric acid etching, but to dentin treated by phosphoric acid etching. The present invention relates to a dental adhesive containing a (meth)acrylamide compound (a), an asymmetric acrylamide-methacrylic acid ester compound (b), and an acid group-containing (meth)acrylic polymerizable monomer (c). The (meth)acrylamide compound (a) is at least one selected from the group consisting of compounds represented by general formula (1), and compounds represented by general formula (2). The asymmetric acrylamide-methacrylic acid ester compound (b) is a compound represented by general formula (3).
