Check out these other articles by USC Ostrow professors: Additional Reading on Orofacial Movement Disorders Once you’re in position, instruct the patient to open wide, close, move forward, right, and left with their teeth apart as you listen for joint sounds. Use one hand to hold the stethoscope on the zygoma in front of condyle, place your other hand under the mandible, and use your fingers to find and apply upward pressure on the inferior bony border of the mandible near the angle. Place a stethoscope over the anterior zygomatic bone, not over the condyle, and listen for joint noise. TMJ Noise Auscultation Under Loading Conditions Like what you’re learning?

For this measurement, ask the patient to “open as wide as possible even if it hurts and hold this position,” and using your ruler, measure the active opening distance as described above.įor the passive or “assisted” measurement, repeat the same process, but this time have your patient open as wide as possible while you apply a small amount of prying pressure with your fingers on their incisor teeth. Next, measure the total voluntary movement ability of their jaw even if pain is present. Next, measure the active opening distance by placing your ruler, such as a TheraBite Jaw ROM Scale, on the incisal edge of the mandibular central incisor and measuring the distance to the incisal edge of the opposing maxillary central incisor. Ask your patient to “open their mouth as wide as possible without any pain and stop and hold when pain first becomes evident.” Pain-freeįirst, you’ll want to see how wide patients can open their mouth without any pain. There are three interincisal measurements to assess a patient’s jaw range of motion: pain-free, unassisted, and assisted. Prior to the procedure, introduce yourself to the patient, explain the purpose of the examination, obtain consent, and be sure to meet infectious control standards.
