I have a patient who wants to get a Removable partial denture. She’d be getting the denture for free through a program my school offers to patients with severe financial need. My school has given me the blessing to prepare rest seats on teeth treated with amalgam fillings. I’d be preparing probably 2 rest seats on amalgam. I recently spoke to a dentist who thinks using anything other than sound teeth or survey crowns for rest seats is a recipe for disaster and that the restorations will fracture. I kind of feel bad doing this procedure only for the denture to be unwearable in a few years due to a fractured restoration . The patient could get survey crowns but it will cost more than they can afford. Just want to get some seasoned Doctors input on the prognosis for this procedure and longevity of the denture.
