When addressing issues with removable partial dentures, what should be evaluated for overextension?

In the context of removable partial dentures, addressing overextension is critical for ensuring a comfortable fit. Overextension can lead to irritation of the soft tissues, discomfort, and can affect the stability and effectiveness of the denture. Therefore, evaluating comfort is essential when assessing for overextension, as a well-fitting denture should not exert undue pressure on supporting structures.

This assessment typically involves considering how the denture interacts with the oral tissues during function, including speaking and eating. If the denture overextends, patients may experience soreness, ulcerations, or difficulty with retention, all of which directly compromise comfort.

While esthetics, function, and the lingual surface are important aspects of removable partial dentures, they do not specifically address the immediate concerns associated with overextension as directly as comfort does. It is primarily the fit and how it impacts the patient's comfort that highlights the issues related to overextension.
