ABSTRACT:
A retention system for dental prosthesis includes an undercasting which is secured to a tooth. A pair of inner shell members are provided, one on each side of the undercasting. A prosthesis is mounted over the undercasting and includes a pair of outer shell members, each of which is disposed against the inner shell member to form a shroud. A resilient pin is seated in the shroud to provide for positive retention of the prosthesis to hold it in place while still permitting its removal.
