We have put together the following information on temporomandibular (jaw) implant devices. The TMJ Association, Ltd. does not endorse any device or manufacturer. We are presenting this for informational purposes only. We would urge extreme caution and careful consideration in making the decision to obtain a TMJ implant device.Replacement of the temporomandibular joint with an artificial implant should be considered a last resort. When used in patients who have had multiple prior jaw surgeries it may improve function, but studies have shown that it generally does not significantly reduce pain. Before undergoing such surgery on the jaw joint, it is extremely important to get other independent opinions and to fully understand the benefits and risks.
