ABSTRACT A denture-retaining unit comprises a ball and socket structure, the socket being adapted for incorporation into a denture. The ball is a sphere having a truncated portion providing a flat base adapted for magnetic engagement with a flat face of a magnetizable keeper, which keeper is adapted to be secured to a support member extending from the jaw. A characterizing feature of the unit is that it permits lateral movement between the denture in which the socket is embedded and the keeper, while the flat faces of the keeper and the sphere remain fully magnetically engaged.
