Permanent prosthesis

There are two types of permanent prostheses :

  • The crowns

A crown artificially reconstructs the crown of the damaged tooth. It can either be simple or combined with a fake-stump fixed into the tooth's root, with a tenon, now made of fiberglass instead of metal.

Advantages : it protects the tooth ; it is unnoticeable.
Drawbacks : the tooth must be trimmed.

  • Bridges

A bridge replaces a missing tooth, by anchering on adjacent teeth (one on each side). This is the same principle as the crown.
A bridge replaces one missing tooth, or two teeth. Beyond two teeth, the risk of breaking is too high.  But we can also put a larger bridge, tied up to many pillars. 

Advantages : it replaces a missing tooth, by using a permanent system (that we do not have to take off and clean everyday).
Drawbacks : mutilating of the pillar teeth, price.

A permanent prosthesis reconstructs a tooth with the most natural result.

Materials : Permanent prosthesis can either be made of : -metal –ceramics and metal - ceramics

  • Metal. Often a gold-based alliage
  • Ceramics. Ceramics are used more and more often. The mechanical characteristics keep improving.
