It is commonly another name for the posterior palatal seal, a controlled seal against the soft tissue near the hard\/soft palate junction. Its plain purpose is to help the denture \u201cseal\u201d against the palate to improve retention and reduce air or fluid leakage. It is planned during denture fabrication and may be refined during adjustments, relines, or repairs."}
