Metal ceramic crown

What is the Metal ceramic crown?

Metal ceramic crowns are a traditional type of crown often used in bridges plus crown and bridge cases.

They are often fitted onto back teeth and are considered a strong, robust type of crown. Another name for this is a porcelain fused to metal crown. They consist of a metal interior or base which is fused to porcelain crowns. The metal interior can be produced from a range of metals, e.g. alloy and this is what gives this crown its strength. When they are made the dental technician first makes a shell of metal that fits over the tooth.

A veneering of porcelain is then fused over this metal (in a high heat oven), giving the crown a white tooth-like appearance. Depending on the requirements of your situation, these crowns are sometimes made where the porcelain veneer only covers those aspects of the crown that is readily visible (meaning the other portions of the crown have a metal surface). In other cases these crowns are pretty much fully surfaced with porcelain.

Advantages and disadvantages of Metal ceramic crown

This type of crown is both robust and long lasting. It is considered a better fit than many other types of crowns and to have greater strength as well.

They are often cheaper than other types of crowns, for example all ceramic crowns.

A disadvantage with this crown is that there is often a structural weakness in the ceramic crown. The crown can be prone to chipping or a fracture.

Also, this is a thicker type of crown which can mean the dentist having to remove a larger portion of your affected tooth. Tooth reduction is a part of the preparation stage but the amount removed depends upon the state of the tooth and the type of crown being fitted.

Finally, there is an aesthetic issue with metal ceramic crowns. What tends to happen is that the metal base begins to appear around the gum line or darkens the porcelain crown. This is more likely to occur in people who have receding gums.
