Correct answer: A — To create a space in the denture base over bony prominences or sensitive areas to prevent tissue damage and pain
A relief area is created by placing a spacer material (tinfoil, wax) on the master cast over bony prominences (median palatine raphe/torus, incisive papilla, mylohyoid ridge) and sensitive areas before processing the denture. This creates a slight gap between the denture base and the tissue over these areas, preventing concentration of pressure on non-stress-bearing tissues that could cause pain, tissue damage, or sore spots. The denture should primarily load the stress-bearing areas (hard palate, buccal shelf, residual ridge).
