Ear insert for relief of TMJ discomfort
A prosthesis for insertion in an ear to reduce pain resulting from TMJ disorders. The ear insert has a predefined shape conforming to the shape of the ear canal when the jaw is in an open position. The ear insert supports the TMJ and associated secondary musculature to reduce strain in the TMJ area, including the muscles, ligaments, nerves, and the temporo-mandibular joint itself. The insert is hollow in the inside to permit hearing and is made of a rigid material which retains the shape of the ear canal. A scalloped indenture extends across a surface of the ear insert positioned behind the tragus.
