HOSA Dental Terminology Practice

Which part of the removable prosthesis serves as a base for the artificial teeth?

1. Framework

2. Connector

3. Saddle

4. Denture base

The correct answer is: Denture base

The term that refers to the part of a removable prosthesis serving as a base for artificial teeth is the denture base. The denture base provides a stable platform upon which the artificial teeth are mounted. It is typically made from a material that mimics the appearance of gum tissue and is designed to fit snugly against the dental arch. The denture base plays a crucial role in the overall functionality of the prosthesis, as it not only supports the teeth but also helps distribute biting forces evenly across the underlying oral structures. It commonly consists of acrylic resin, which is favored for its aesthetic qualities, adaptability, and comfort for the patient. In contrast, the framework refers to the underlying metal structure that supports the denture base and is primarily used in partial removable dentures. A connector is a component that connects different parts of the prosthesis but does not serve as the base for teeth. The saddle is a term that refers to the area of the denture that contacts the residual ridge of the jawbone but is not the complete base. Thus, selecting the denture base correctly identifies the part specifically responsible for supporting artificial teeth.
