What term describes dentures that replace all teeth in an arch?

• A. Complete dentures
• B. Partial dentures
• C. Fixed bridges
• D. Implants

Answer: (A)

The concept being tested is how dentures are classified by coverage of the dental arch. When every tooth in an arch is missing and a removable prosthesis is designed to replace the entire set, this is called complete dentures. They provide a full arch solution and are worn in the mouth to restore function and aesthetics. This differs from partial dentures, which replace only some teeth and rely on remaining teeth for support; fixed bridges, which are cemented and non-removable; and implants, which are root-like fixtures used to support various prostheses rather than by themselves describing a denture that covers all teeth in an arch. So, dentures that replace all teeth in an arch are complete dentures (also referred to as full dentures).
