ABSTRACT:
A pillar attached directly or indirectly to the jawbone, has an accessible snap-in ball socket. A ball attached to and projecting from an overdenture or other removable prosthesis is sized to enter the socket after being forced through its restricted opening. The overdenture is fitted in such manner that in the absence of occlusal forces, the ball lies at or just inwardly of the restriction. The socket is extended inwardly so that, upon the application of occlusal forces, the ball moves deeper into the socket without imposing stress upon the pillar or its supporting structure. Yet lateral stability is provided.
