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