All-ceramics crowns and bridges represent absolute leading edge of modern dental medicine. They present fixed dentures without metal construction. That is made by CAD/CAM technology from Zirconium oxide. Construction from Zirconium oxide is perfectly precise thanks to computer manufacture. On this construction is burnt layer of ceramics. Due to this manufacturing process we are able to achieve engraining and transparentness of tooth from depth, better permeability and reflection. In a high quality aesthetically made all-ceramics tooth cannot be sometimes recognized from real one even from specialist. All-ceramics teeth are suitable, after indication from dentist, for anybody who does not wish to have any metal in mouth, which causes unwanted dark edges necks of teeth, colouring gums by oxidation, allergies. Zircon crowns and bridges, how they are sometimes also called, are not only the most solid ceramics dentures nowadays but also they have similar physical qualities (they extend by heat, contract by cold) for which they are indicatively more suitable than metal-ceramics dentures.
