Final answer:
In maxillary denture construction, palatal tori are not typically removed. Surgical intervention may be necessary if there are significant undercuts, if the tori impinge on the soft palate, for immediate denture construction, or when creating a denture with a metal base.
Step-by-step explanation:
The maxillary bone or maxilla forms part of the upper jaw, and includes the alveolar process where teeth are anchored, and the palatine process which joins to form the hard palate. The hard palate separates the oral and nasal cavities. When constructing a complete maxillary denture, palatal tori, which are bony growths in the palate, are not typically removed unless specific conditions require surgical intervention. Such exceptions include when marked undercuts are present that could complicate the denture fit, when tori impinge on the soft palate causing potential discomfort or interference, when an immediate denture is to be constructed requiring a smooth surface for proper fit, or when a denture with a metal base is being made, which requires a precise adaptation to the underlying bone structure.
