Are combination dental crowns common?

A porcelain fused to metal crown, or composite bonded to metal, is very common. With the proper preparation, attention to the health of the gingiva, and care and skill in lab procedures, the veneered metal crown can be a fine restoration.

There are times, however, when it is not advisable to use a combination crown. Such a situation would be in the back of the mouth on a second molar, where fracture of the porcelain may more commonly occur. Also, in areas where the dentist can only prepare/shape the tooth minimally there may not be room for porcelain. In these cases a full cast all metal crown is indicated.
Combination dental crowns made of metal and porcelain are fairly common because they provide the look of a natural tooth, unlike metal crowns, without the higher price tag that comes with a crown made completely of porcelain. Since the porcelain on a combination dental crown is bonded to a metal support, it is also much stronger than a crown made only of porcelain. Given the use of metal, a combination dental crown may not be the best choice for people with known allergies to metal. Ask the dentist for information about what type of metal is used in the manufacturing of a combination dental crown to help decide whether it is the best option.
