Final answer:
In complete denture construction, the retromolar pad area should be relieved shorter than other areas of the baseplate for comfort and proper function.
Step-by-step explanation:
When constructing a complete denture, the area of the baseplate that should be relieved shorter than other areas is the area of the retromolar pad. This area has underlying glandular tissue as well as a pear-shaped pad that needs space to function properly while chewing. The relief of the retromolar pad area ensures that the baseplate does not impinge upon this sensitive area and allows for natural movement without discomfort.
