  • All-ceramic Crowns
  • Metal ceramic Crowns

All-ceramic crowns:

Zirconium crown is a well-known type of all-ceramic crown which significantly improves the tooth esthetic. A zirconia crown is made of a strong, biocompatible material, zirconia, which has also got medical applications like artificial joints. Patients are least likely to develop an allergic reaction to this material and thus considered a safe option when compared to porcelain fused to metal crowns.

Zirconium also called Zirconia (Cercon) is rapidly becoming the preferred material for dental crowns. The aesthetic of Zirconium crowns is its biggest advantage. Zirconium crowns are translucent and resemble to a natural tooth and reflect light the same way. This is particularly important when it comes to using them for the front teeth. There is not metal used with Zirconium crowns therefore there is no black gum line that you can see around a porcelain fused metal crown.

Zirconium crown is extremely durable and long lasting material and withstands wear and tear in compare with other types of crown.It requires minimal tooth shaping and adjustments¬ therefore preserves most of the natural tooth, which is ideal while removing the crown. It requires minimal tooth shaping and adjustments¬ therefore preserves most of the natural tooth, which is ideal while removing the crown. Hence, zirconia crown is an ideal option to cover-up the damage including stains and to restore the tooth function.

Metal ceramic crowns:

Porcelain is the conventional material used for making crowns. Porcelain fused to metal crown is a full cast crown that is made by fusing the porcelain to the metal surfaces. The main advantage of Porcelain fused to metal crown is its strength that comes from the metal substructure. However; full porcelain can chip or break. With porcelain-fused-to-metal crowns the aesthetic of the tooth can be spoiled by the metal edge that shows right where the crown meets the gum.
