ABSTRACT:
A denture is fitted with a U-shaped magnet element which provides for enhanced denture retention by coupling magnetically with a magnetizable element which is located in a decoronated tooth or dental implant in the mouth of a person to whom the denture is fitted. The magnet element is substantially totally enclosed within a base of the denture but pole caps are mounted to respective pole faces of the magnet element and are exposed to engage in abutting contact with the magnetizable element. The pole caps are formed from ferro-magnetic stainless steel and function to protect the magnet element from chemical attack and/or mechanical damage in the oral environment.
