These are porcelain crowns that no substructure materials have been used and strength have been improved through the machining of the ceramic with compression. The full porcelain structure without any metal within the substructure increases its transparency. Therefore, they look very natural by imitating the transparency of natural teeth, light permeability and reflection characteristics.
They are preferred for anterior teeth where the chewing forces are smaller and in single lacking teeth. They cannot be used in bridges. Zircon crowns can be used in lateral and posterior teeth where the chewing forces increase.
