Correct answer: B — The component that rests on the edentulous residual ridge and supports the artificial teeth
The denture base is the component of the RPD that rests on the edentulous residual ridge mucosa and supports the artificial (prosthetic) teeth. It can be acrylic resin (most common), metal (cast framework with attached teeth), or a combination. In distal extension RPDs, the denture base is the primary tissue-support component — it distributes occlusal forces to the residual ridge through the underlying mucosa. Proper extension, tissue adaptation, and border seal of the denture base are critical for stability, support, and patient comfort.
