What is the term for the metal extension on a partial denture that holds the artificial teeth?

The term for the metal extension on a partial denture that holds the artificial teeth is known as the framework. The framework is the supportive structure of the partial denture, typically made of a metal alloy, which provides stability and retention for the denture as a whole. It consists of various components that help to distribute forces effectively across the remaining natural teeth and bone structure.

In a partial denture, the framework is crucial because it helps secure the artificial teeth in place while allowing for comfort and function during chewing. This part bridges the gap where teeth are missing and supports the components that hold the artificial teeth, ensuring that they remain well-positioned and that the partial denture functions properly.

The other terms relate to different components of a denture. The retainer refers to the part of the denture that clasps around the remaining natural teeth to keep the denture securely in place. The saddle is the portion of the denture that rests on the alveolar ridge and may support the artificial teeth but is not specifically the metal framework. Rests are projections that help distribute occlusal forces to the remaining teeth or the tissue but do not encompass the entire structural framework that holds everything together.
