  • Patent number: 4530663
    Abstract: A closed field magnetic denture retention unit which includes a ferromagnetic cup containing a cylindrical permanent magnet, 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 to close the magnetic field when the denture is in place. The unit serves to retain the denture in place by magnetic attraction, the keeper forming a closed magnetic field so that there is not external magnetic field in the mouth of the patient.
