Disclosed herein are methods for creating opalescence in dental materials and restorations, compositions used in such methods, and the resultant dental materials and restorations. More particularly, the opalescence may be created by directly embedding opalescent particles into a matrix material. In some embodiments, photonic crystals are embedded in the dental material to achieve the opalescent effect. Photonic crystal particles may be embedded in dental materials matrices such as ceramics, composites, and polymers, and can generate opalescence in the materials. Some embodiments disclose compositions for applying the opalescence to a dental restoration.

A dental polymerizable composition including a glass powder and a (meth)acrylate is provided. The glass powder includes zinc, silicon, and fluorine and is substantially free of aluminum.

Provided herein are novel compositions for the restoration of demineralized tissues, such as dentin which has been demineralized by tooth decay. The remineralization agent comprises a bioactive ceramic component and a polyanionic macromolecular component, which may be admixed and applied to the target tissue and which will subsequently set to produce a remineralizing solid. The remineralizing solid will produce nanodroplets of mineral precursor solution, which such nanodroplets can infiltrate demineralized collagen matrices and which will form hydroxyapatite crystals therein by polymer-induced liquid precursor processes. The scope of the invention encompasses novel compositions and methods of treating demineralized tissues.

The present invention relates to free-radically polymerizable compositions for 3D printing of dental crowns, bridges, prosthetic teeth or full prostheses which on account of their filler combination feature very good mechanical properties and optimal sedimentation stability.
