Metal-supported prostheses, which are widely used, create a chalky appearance when used in the anterior region due to their lack of light transmittance. In addition, greyish purple gingival edges can be observed with the reflection of the metal used as a substructure on the gingiva. Since this is not natural, it does not look pleasing to the eye.
When empress, which is a kind of reinforced porcelain, is used instead of metal substructure, a perfect tooth and gingival aesthetics can be achieved since its light transmittance is very similar to natural teeth and there is no metal in its structure. In other words, empress crowns are a kind of aesthetic coating that does not contain metal.
