This type of treatment require no/very little preparation of teeth and although it is not suitable in all cases could be a very good option to replace 1 missing tooth in the anterior area. 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. These type of bridges last up to 7 years if bonded on sound tooth structure.
These involve preparation ( reducing the size ) of the abutment teeth and the bridge would be conventionally cemented on in place. They can be made in metal-ceramic or all ceramic and they can replace 1 or more teeth.
