Correct answer: C — Over-extended posterior border of the denture

Gagging with a maxillary complete denture is most commonly caused by over-extension of the posterior border (post-dam area) into the soft palate. The soft palate is a gag-trigger zone, and contact with this area stimulates the gag reflex. Correction involves shortening the posterior border to the vibrating line (junction of moveable and immoveable palate). Over-extended flanges (buccal or labial) can also contribute.
