An artificial substitute for all of the natural teeth in one arch.

An artificial substitute for all of the natural teeth in one arch.

• A. Partial denture
• B. Implant
• C. Full denture
• D. Bridge

Answer: (C)

Replacing all natural teeth in one arch with an artificial substitute is called a full denture. This prosthesis restores function and appearance when every tooth in that arch is missing. It sits on the mucosa over the alveolar ridge and is typically removable, though there are implant-supported versions. In contrast, a partial denture replaces only some missing teeth and uses the remaining teeth or implants for support. An implant is a surgically placed fixture that can support crowns, bridges, or overdentures but doesn’t by itself replace all teeth in an arch. A bridge spans a gap by attaching to adjacent teeth. So the term that describes replacing all teeth in one arch is full denture.
