ABSTRACT:
A closed field magnetic denture retention unit which includes a ferromagnetic cup containing a cylindrical permanent magnet which is displaced down from the top of the cup, the cup and magnet being embedded in the denture; and a magnetic keeper which is embedded in an exposed tooth root in the mouth of a patient and extends across the top of the cup in contact with the peripheral edge of the cup but not with the magnet, the keeper serving to close the cup when the denture is in place to retain the denture in place by magnetic attraction, the keeper forming a closed magnetic field so that there is no external magnetic field in the mouth of the patient.
