The FDA has approved Walter Lorenz Surgical’s Total Mandibular Joint Replacement System (TMJ) for use in patients with severe mechanical damage to the mandibular joint. The device consists of 2 components: a polyethylene fossa piece (attatched to the skull just in front of the ear) and Cobalt-Chromium-Molybdenum (Co-Cr-Mo) mandibular piece attatched to (what’s left of) the jaw itself.
