 # Excess height of the posterior palatal seal of a complete maxillary denture will usually result in which of the following? A. Gagging B. Increased retention C. A tingling or tickling sensation D. Unseating of the denture The correct answer is D. Unseating of the denture. Over contouring or excessive beading of the posterior palatal seal causes too much pressure to be exerted on the palatal tissues resulting in the unseating of upper dentures. The posterior palatal seal is typically placed approximately on the vibrating line between the hard and soft palate and provides a physiologically acceptable tissue pressure within the compressible portion of the soft palate to attain retention and peripheral seal. Over extending the coverage of seal will cause gaggling and painful swallowing for the part of the patient.
