A metal free ceramic crown, Cercon, remains unnoticeable even for an expert eye from 5-10 cm. Cercon has been developed by Swiss researchers. When preparing Cercon, the lab technicians use CAD/CAM technology to design the anatomical features, size and shape of a tooth restoration on a computer. Single crowns for front teeth and molars, maximum two Pontiacs by bridges, all-porcelain crowns can be done with this. The Cercon is metal-free, so it is anti-allergic. It meets the strictest requirements of implantology. Since the reactions of the soft tissues to it are excellent, the gum remains healthy around the crowns and bridges with 5 years warranty.
