Which of the following could be a reason for RPD framework rejection?

The decision to reject an RPD framework often stems from multiple fit-related issues, which can affect the overall function and comfort of the prosthesis. If the framework does not fit the cast, it indicates that the design may not accurately represent the patient's oral anatomy. A poor fit at this stage can lead to complications in the seating of the denture in the mouth.

When the framework does not fit the palate, it can cause discomfort and may hinder proper retention and stability, ultimately impacting the patient's ability to use the RPD effectively. Similarly, if the framework does not fit the teeth, this could lead to instability, improper occlusion, and could also affect the esthetics of the denture.

Recognizing that any of these fit issues - whether pertaining to the cast, palate, or teeth - is sufficient reason for rejecting the framework underscores the importance of precision in the fabrication process. Each component must work harmoniously for the RPD to be successful, making the option that includes all potential fit problems the most comprehensive and accurate response.
