Metal-free crowns are a type of highly aesthetic restorations entirely made of ceramic. They can imitate natural characteristics of teeth, transmitting light like natural teeth. They fit in alignment much better, particularly if only some teeth are restored, rather than all of them. In such cases it is impossible to make a difference between Metal-free crowns and natural teeth. Their interior is made of materials described as biocompatible, which means that they do not cause any reaction of the surrounding tissue, enabling the gingiva to shape around them as if they were natural teeth. Metal-free crowns are a combination of supreme quality and durability.
In most cases, Metal-free crowns are made of zirconium or lithium-disilicate ceramic. In such a way the produced crown is made of a material similar to glass; it is light and transparent, and at the same time as resistant as natural teeth.
