Ceramic Materials and Color in Dentistry

The aesthetics of a dental restoration depends on the chosen material, anatomical form, surface texture, translucency and color. This means that, to accurately reproduce the appearance of a natural tooth, considering the patterns of reflection and absorption of the light is not an easy task (Knispel, 1991; Chu et al., 2004). Ceramics have been widely used in dentistry because of their ability to provide excellent cosmetic results that mimic natural teeth. They are biocompatible, allow adequate reflection and transmission of light, and they exhibit good mechanical strength when subjected to masticatory efforts (Holloway & Miller, 1997). The rapid development of ceramic systems and processing enabled the treatment of teeth in both the anterior and posterior areas, with the primary objectives of properly restoring form, function and aesthetic excellence without the presence of metal.
