The ceramic (porcelain) fused to metal crown is a relatively cheap, aesthetic and resilient type, therefore these types of crowns are used for crown preparations in the back region, on molar teeth. Although more and more patients opt for zirconium crowns, porcelain fused to metal crowns are still a very viable option. The picture shows the difference between a zirconium and a porcelain-fused-to-metal crown: metal-free zirconium crowns on the front teeth naturally transmit light through the crowns – this is no longer the case with the posterior ones, as there is a metal frame under the porcelain. We have eliminated the metal alloys containing nickel, and using cobalt-chrome alloys instead, eliminating possible allergic reactions that might occur with alloys containing nickel. For the maximal aesthetic effect, instead of the usual metal margin our technicians cover this part with special shoulder-ceramic, to prevent the appearance of the unpleasant “gray gingiva” effect.
