An abutment is a tooth used to carry the false tooth. A pontic is the term given to the false tooth. There are two types of bridges commonly used in dentistry:
These require no/very little preparation of teeth. The bridge consists of a false porcelain tooth with a metal wing. The metal wing is bonded onto the tooth adjacent to the space with an adhesive dental cement. RBBs can last up to 7 years.
Traditionally bridges involved preparation of the abutment teeth (similar to crown preparations) and the bridge would be conventionally cemented on in place. They are good for replacing one or more teeth and this type of bridge has a long history of success. They can be made in metal-ceramic or all ceramic.
