Guide to Evaluation of Permanent Impairment of the Temporomandibular Joint

This guide provides a method for evaluating permanent impairment due to injury of the temporomandibular joint (TMJ). Each author represents a major organization whose members treat displacement and joint degeneration, (2) range of motion, and (3) surgery. The rating values are comparable to those provided in the American Medical Association Guides to the Evaluation of Permanent Impairment for functional and disc-protected joints, so TMJ impairment values obtained by use of this guide can be combined with values for other impairments rated in accord with the AMA Guides. This guide for rating of TMJ impairment is intended for individualized application. A conservative attitude and sound clinical judgment are recommended.
