Final answer:
The correct statement about a fixed bridge is that it consists of at least one abutment and one pontic. A fixed bridge replaces missing teeth and is anchored to abutment teeth while using pontics to fill the gap.
Step-by-step explanation:
The statement that is true of a fixed bridge is: C) A fixed bridge consists of at least one abutment and one pontic.
A fixed bridge is a type of dental restoration that replaces one or more missing teeth. It extends across an area that has no teeth and is typically anchored to one or more abutment teeth on each side of the gap. The bridge is a structure composed of several parts: the abutment teeth (which are prepared and serve as the supports for the bridge), the pontics (the artificial teeth that fill the gap and restore the dental arch), and the retainers (crowns fitted onto the abutments).
While statement B is also true, as the fixed bridge is described by the number of units involved, which includes the abutments and pontics, it is the combination of at least one abutment and one pontic that comprises the essential elements of a fixed bridge.
