Mandibular prosthesis and a temporomandibular anchor for jaw reconstruction

摘要

There is provided a mandibular prosthesis comprising: temporomandibular anchor configured for fixation to a temporal bone in use; and a mandible portion having at least one ascending ramus portion, wherein the ramus portion and the temporomandibular anchor portion are secured together by a rotational attachment such that the mandible portion is able to: rotate at least anteroposteriorly with respect to the temporomandibular anchor; and travel mediolaterally with respect to the temporomandibular anchor to facilitate chewing and opening and closing of the prosthetic mandible relative to the upper jaw. There is also provided a temporomandibular anchor configured for fixation to a temporal bone in use wherein, the temporomandibular anchor is configured for forming a rotational attachment with a mandible portion such that the that the mandible portion is able to: rotate at least anteroposteriorly with respect to the temporomandibular anchor; and travel mediolaterally with respect to the temporomandibular anchor to facilitate chewing and opening and closing of the prosthetic mandible relative to the upper jaw.
