    摘要: A rigid bar arranged to removably support an artificial denture is curved in the shape of the lower jaw bone and has front implant support means as well as rear ramus implant portions. Each of the ramus implant portions includes a tip end of the frame arranged to be inserted in a rearwardly extending opening cut in the jaw bone by the dentist. Such tip ends have laterally extending flattened portions which provide increased bearing support on the jaw bone. The front implant support comprises a depending extension arranged to be inserted in a recess cut in the top surface of the jaw bone, and such extension has a cross blade with one or more forwardly extending tabs arranged to seat on surface portions of the jaw bone. The cross blade may also have rearwardly extending tabs arranged also to seat on surface portions of the jaw bone. The invention further includes the concept of providing partial length rear support bar portions arranged to be implanted at their rear tips in ramus portions of the jaw and arranged to be fastened to a front portion of a support bar.
