COERCIVE APPARATUS FOR DETACHABLE DENTURE

Japanese Patent JPS63122449

A

A removable dental prosthesis is magnetically secured to an anchor face of a ferromagnetic body implanted in a jaw by an attachment system comprising a saliva-resistant cushioning mass secured in the prosthesis and forming a pocket open toward the anchor face, a ferromagnetic and saliva-resistant shell seated in the pocket and open toward the face, a permanent magnet fixed in the shell and having a magnet face confronting the anchor face, and a permanently magnetized plate having a rear face directly contacting the magnet face, a front face directly confronting the anchor face, and an outer periphery. The plate is of a material not corrosible by saliva and is magnetically polarized like the magnet which itself is of relatively great strength and of a material corrosible by saliva. The outer periphery of the plate is sealed to the shell so as to encapsulate the magnet in the shell with the plate and thereby protect it from corrosion. With this system the flux of the magnet passes substantially entirely via the plate to the anchor body when the front and anchor plates are closely juxtaposed.
