What is a three unit provisional bridge?

A bridge is a dental prosthesis uses to close, or bridge, the gap of a missing tooth. It is the adjoinment of two or more teeth, with the abutments on the first and last teeth. To comfortably fit the bridge in the mouth, the enamel must be removed on the abutments. The artificial teeth that fill the space of the missing ones are called pontics. A three unit provisional, or temporary bridge, is a type of bridge with two abutments and a pontic between them that is made of composite materials rather than ceramic, feldspar, single or disilicates, or zirconium as is used in other types of bridges.

Although uncommon, it is only used when waiting for a permanent bridge to be made from the lab.
