The technique for preparing the arbitrary posterior palatal seal demonstrated. Orig. air date: APR 9 74 This is part of the Open.Michigan collection at: open.umich.edu/...
nice video BUT the instruction is competely false, the posterior palatal seal or the post dam should be like a bump. you have to carv the palate about a mm deep at the end border. when you hold the denture in your hand you should see two bumps like a camel back on both sides of the palatal fovea.when the patient pushes the denture up so that that bumps work like suction to create vacum and hold the denture firm in place OK.
Nice....finally someone that made some sense, its been amateur hour the last 4 vids I watched.
Great video!
nice ,useful for all dentist
