In today's dental technology mostly ceramic crowns do not need to use metal framework for support and strength. They are prepared from special porcelain reinforced structure. Fabricated from high-strength ceramics, they are biocompatible, durable, and unmatched in esthetics. Since the core material of these crowns is the color of the tooth instead of the metal, the restoration has all the translucency, luster, and light reflection of a natural tooth; and there are no any dark metal bands around the neck of the crown to hide.
As result we come out with fabulous light transmission and imitate all super esthetic properties of the natural tooth.
