Cercon® full-ceramic crowns
State-of-the-art non-metallic zirconium ceramic system based on CAD/CAM technology. The technology is based on computer scanning and preparation of material being a special composite of zirconium ceramic ZrO2, stabilised with Y2O3 oxide. This material allows for fillings in any part of the arc up to the size of a seven-point bridge. Note that the advantages and characteristics of work made with CERCON system are difficult to compare, as conventional materials used in laboratories are not even a close match to the possibilities offered by this technology.
