Abstract
A sleeve attachment system and method for more precise and rapid preparation of overdentures and implant borne bar systems used to support overdentures. The system includes an elongate bar and a prefabricated sleeve with an attached retractable locking device wherein the sleeve is precisely prefitted to receive the elongate bar and the retractable locking device is precisely aligned to engage the elongate bar through an aperture in the elongate bar when the elongate bar is seated in the sleeve. The elongate bar and the sleeve with an attached retractable locking device are assembled and milled as a matched set for inclusion and use in the preparation of an implant borne overdenture prosthesis system, with the elongate bar attached as a distal end of a bar system infrastructure fitted to implants and the sleeve with attached retractable locking device cast in the underside of the overdenture such that when the overdenture is placed over the bar system infrastructure, the elongate bar seats in the sleeve and the retractable locking device engages the elongate bar creating a stable support point for the overdenture.
