Abstract
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.
