  • Patent number: 4377382
    Abstract: A rigid bar arranged to removably support an artificial denture is curved substantially to the longitudinal contour of the lower jaw bone. This bar has a front support arranged to be implanted in a front recess in the jaw bone and also includes a rear ramus implant portion on each side arranged to be implanted in the ramus portions of the jaw bone. Each of the ramus implant portions comprises a plate-like extension of the rigid bar having laterally facing surfaces. This rearward plate-like extension has an elongated length so as to project above or below the plane of the bar or in a preferred construction, such extension projects both above and below such bar to provide an extended implant attachment to the jaw bone structure. The plate-like extension angles forwardly from top to bottom so that it can be embedded efficiently in the rearward portion of the jaw bone.
