Computerized Mandibular Scanning


 

Computerized Mandibular Scanning (CMS) is a more complex assessment of mandibular function using biomedical instrumentation which measures the rotational movement in the frontal and sagittal planes thus confirming a neuromuscular dysfunction. The computerized mandibular scanner measures jaw movement, both qualitatively and quantitatively in several dimensions, to within 0.1 millimeters of accuracy. Using a magnetic tracking device and sensor array, the scanner projects the data on a calibrated computer monitor.

The CMS measures jaw movement far more accurate than the eye, making it possible to document characteristics of mandibular motion considered significant to evaluate jaw function. It also identifies the amount of free space, the swallowing pattern, and the quality of the occlusion, and substantiates the presence of disc derangements and their prognosis for reduction. It is a multi-dimensional assessment of torquing movements used to differentiate between contributing factors of a pathologic position to a non-pathologic position on opening and closing of the mandible. It is used in conjunction with EMG recordings.

Graphic recording of opening/closing paths of jaw movements from the side and front views can be analyzed to assess abnormal mandibular paths of movement. The speed at which the jaw can open and close is also simultaneously recorded.

The literature supports the efficacy of mandibular tracking in the diagnosis and treatment of TMJ/MSD:

  • There are over 22 controlled published studies that further support the rationale for mandibular jaw tracking.
  • There are 25 additional supporting referenced studies confirming the same.
  • There are numerous other studies that document the clinical efficacy and validity of computerized mandibular scanning.
