ABSTRACT:
A magnetic dental retention appliance comprises a magnet containing subunit to be embedded in a denture, a magnetizable keeper subunit to be secured within the jaw structure of the patient for retaining the denture in the mouth, and a transmucosal insert to be implanted in the patient's jawbone for anchoring the keeper subunit to the patient's jaw; the transmucosal insert being formed of a material ideal for implantation and diverse from the requisite ferromagnetic material of the magnetizable keeper subunit; the insert being isolated from the keeper subunit by an interposed insulating member which effectively curtails or prevents corrosive galvanic action between the two, thereby facilitating use of the most ideal materials of construction for the subunits and the insert.
