Describe the fovea Palatinae

Can the fovea palatinae be used to accurately locate the posterior palatal seal area?

Hardy attributed some denture failure to improperly locating the hamular notches. Describe the technique he used.

" He suggested the use of a "T" burnisher to identify the notch since the instrument will drop into the notch and identify it without question".

The posterior border and the posterior palatal seal are two of the most critical areas for maxillary denture retention. What classification will help designate the shape of the soft palate and describes the amount of posterior tissue that will accept the posterior palatal seal? Millsap pg 666

  • House’s Palatal Throat form:

  • Class I: 5-13mm distal (more than 5mm of movable tissue available) Ideal for retention

  • Class II: 3-5mm distal (1-5mm of movable tissue available) Good retention

  • Class III: 3-5mm anterior (less than 1mm of movable tissue available) Poor retention

  • Class III difficulties are in tissue movement, typically present in high vaulted patients, and because of the small area for the posterior palatal seal.
