ABSTRACT:
A temporomandibular joint (TMJ) diagnosis device easily incorporates into the handle of a dental mirror or the like. Marks indicating distances critical to the evaluation of TMJ articulation are engraved or otherwise permanently made upon the handle of a dental instrument, particularly an angled dental mirror. By resting or setting the butt end of the handle against the incisal edge of either mandibular or maxillary teeth, a dental practitioner can easily gauge proper TMJ functioning and alignment as the patient slowly opens the mouth. Any misalignment is indicated by the relative motion of the opposing jaw portion with respect to the handle side which is generally perpendicular to the butt end. Generally, a mark can be engraved or otherwise made at forty-five millimeters to indicate generally the proper range of TMJ articulation. Likewise, collateral marks can be made sixty millimeters, fifty-two millimeters, thirty-eight millimeters, and twenty-five millimeters. The marks at fifty-two millimeters and thirty-eight millimeters can be used to evaluate proper lateral TMJ articulation when the forty-five millimeter mark is used as a central point against which the lateral articulation of the TMJ can be gauged. In an alternative embodiment, two dissimilar surfaces both visually and tactically perceptible can be used to indicate a ten millimeter range to approximate the proper TMJ articulation distance. By estimating a center line within the ten millimeter band, the lateral articulation of the TMJ can be estimated and gross departures from the norm can be easily detected.
