HOSA Dental Terminology Practice

In a removable prosthesis, what does the term saddle refer to?

1. Part of the framework

2. Connector used for support

3. The base for placement of artificial teeth

4. Part that straddles the gingival crest

The correct answer is: Part that straddles the gingival crest

The term "saddle" in the context of a removable prosthesis refers specifically to the part that straddles the gingival crest. This area is crucial as it serves as the foundation for the prosthetic components, providing support and stability for the artificial teeth. The saddle typically encompasses the area of the gums that is meant to replicate the natural contours of the edentulous (toothless) ridge, allowing for a good fit and distribution of occlusal forces during chewing. Understanding the role of the saddle is vital in prosthodontics, as it is designed to adapt closely to the contours of the gum tissue, which helps in maintaining the retention and overall functionality of the removable prosthesis. Properly designed saddles can help minimize movement of the prosthetic device and improve patient comfort.
