Utilizing the optical properties of composite resins to improve esthetics: a layering technique for anterior...

A comprehensive knowledge of the optical properties of composite resins is essential to achieving optimal results in direct anterior restorations. This case report describes an anterior composite resin restoration fabricated with a layering technique and explains how to use a simple photographic method to verify that the desired optical effects are reproduced. A Class IV restoration was completed on a maxillary central incisor with the help of a silicone guide. An esthetic result was achieved through careful color examination as well as material selections that were based on knowledge of the translucency, opacity, and fluorescence of the chosen direct composite resins. The approach of combining a composite resin designed for bleached teeth with highly opalescent and translucent resins as well as matching the natural dental anatomy provided excellent esthetic results. The suitable reproduction of optical characteristics was confirmed by increasing the contrast of the final photograph, which highlighted the translucency achieved in the area of the mamelons.
