A three unit porcelain fused to metal bridge (PFM)

A bridge is a fixed dental restoration (a fixed dental prosthesis) used to replace a missing tooth (or several teeth) by joining an artificial tooth permanently to adjacent teeth or dental implants.

Conventionally, bridges are made using the indirect method of restoration.

A bridge is fabricated by reducing the teeth on either side of the missing tooth or teeth by a preparation pattern determined by the location of the teeth and by the material from which the bridge is fabricated. In other words, the abutment teeth are reduced in size to accommodate the material to be used to restore the size and shape of the original teeth in a correct alignment and contact with the opposing teeth.

The materials used for the bridges include gold, porcelain fused to metal, or porcelain alone. The amount and type of reduction done to the abutment teeth varies slightly with the different materials used. The recipient of such a bridge must be careful to clean well under this prosthesis.

When restoring an edentulous space with a fixed partial denture that will crown the teeth adjacent to the space and bridge the gap with a pontic, or “dummy tooth”, the restoration is referred to as a bridge.
