ABSTRACT:
A denture retaining unit comprises a ball and socket structure, the socket being adapted for incorporation into a denture. The ball is a truncated sphere providing a flat face 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. The unit permits lateral and/or angular 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. The sphere and the keeper have interengaging portions for limiting lateral movement therebetween and for preventing disengagement of the flat faces of the keeper and the sphere.
