Title: Denture retention

Abstract: A method of retaining dentures in position by use of magnets. A first magnet element is mounted to a support associated with a person's jawbone, such magnet element being exposed at or above the gingival margin of the person's gum, and a second magnet element is located in the denture. The second magnet element aligns with and abuts the first magnet element when the denture is fitted to the patient. Retention is achieved by way of magnetic attraction between the first and second magnet elements, one at least of which is a magnet that exhibits a magnetic field.
