Abstract
Abstract An implant supported prosthesis, and a method for making an implant supported prosthesis, including a framework cast from a wax-up frame, at least one implant abutment, a fixation means for securing at least one abutment to the mouth and at least one cylinder securely attachable to each of the at least one abutments. The framework is cast including the casting of surfaces defining at least one aperture. The framework is mounted in the mouth with the at least one aperture receivably mating with the at least one cylinder. The framework may then be bonded onto the at least one cylinder by use of a luting material.
