A metal-free translucent ceramic crown, Cercon, remains unnoticeable even for an expert eye from 5-10 cm. Cercon has been developed by Dentist Swiss researchers. When preparing Cercon, the lab technicians use CAD/CAM tecnology to design the anatomical features, size and shape of a tooth restoration on a computer. The CAD/CAM computer screen displays a 3-D image of your teeth and gums. The Cercon system provides high stability. It is anti-allergic, translucent, biocompatible and has low thermal conductivity
