Summary: | Dental articles including at least one optical surface formed of a multilayer optical film including layers of at least one strain-induced birefringent material are disclosed. The multilayer optical films included in the dental articles is preferably post-formed into desired non-planar shapes in manners that result in some deformation of the optical stack of the multilayer optical films. A variety of dental implements can be constructed with multilayer optical film including dental mirrors, light guides for use in connection with photo-curing dental materials, and matrix bands for use in molding photo-curing dental restoratives. |
