6 purposes of posterior palatal seal

By Dr.Swathi Pai on Saturday 17 January 2009 with 0 comments



  1. Retention of maxillary denture

  2. Firm contact with the palatal tissue reduces the gag reflex

  3. It reduces food accumulation

  4. The pressure on the tissue makes the distal border of the denture less noticeable to the dorsum of the tongue.

  5. It compensates for dimensional change

  6. The thickened area provides added strength across the denture

  • The denture on soft resilient tissues will allow the mucosa to move with the denture base during function and maintain the denture seal.
