A bridge is a fixed dental restoration used to replace one or several missing teeth, by joining an artificial tooth/teeth permanently to adjacent teeth or dental implants.
The design of the bridge can vary depending on how they are fabricated and they way the anchor to the adjacent teeth.
Like crowns, the bridges are done to measure by a dental laboratory and they can be built in different materials: metal alloys only, porcelain fused to metal or porcelain alone.
