Which removable prosthesis replaces one or more teeth in the same arch?

• A. Fixed bridge
• B. Complete denture
• C. Removable partial denture
• D. Overdenture

Answer: (C)

Replacing one or more teeth in the same arch with a removable prosthesis is achieved by a removable partial denture. This type is designed to fill gaps while preserving the remaining natural teeth, and it can be removed for cleaning. It is supported by the existing teeth and the surrounding soft tissue, often using clasps or other connectors to grip the adjacent teeth.

This differs from a fixed bridge, which is cemented to adjacent teeth and cannot be removed. It also differs from a complete denture, which replaces all teeth in an arch rather than just some. An overdenture sits over retained tooth roots or implants and is typically used to support a denture when some roots remain, but it is not the option chosen when only a subset of teeth in the arch needs replacement.
