Crowns consist of the metal carrier constituting the inner part and from laid on this carrier of a few thin layers of ceramics of different shades and translucency. The base of metal provides a very good mechanical strength, however porcelain which entirely is covering metal is guaranteeing the satisfying aesthetic effect.
This type of crowns is suitable perfectly for a reconstruction of teeth, even though the metal present beneath the crown doesn’t fully allow to obtain natural for front teeth effect of translucency.
In case of deeply sub-gingivally destroyed teeth porcelain crowns on the base of zirconium are a better solution. Using zirconium minimizes the risk of the appearance under the crown of the recurring tooth decay. It is also necessary to apply this type of crowns with individuals having an allergic reaction to a presence of some common metals, because allergies to zirconium isn’t possible.
We apply chromium cobalt metal in our institution thus minimizing the potential allergy to elements appearing in other metals.
The metal base is made in the technology of the CAD/CAM, which we are achieving the perfect accuracy of the crown and consequently thanks to certainty that the own tooth of the patient beneath the top won’t yield to the recurring tooth decay.
