At the TMJ & Sleep Therapy Office, we pride ourselves on using the most current, proven and accepted non-invasive diagnostic equipment available to help identify your particular situation and treatment needs. This encompasses leading technologies used to diagnose TMJ problems and monitor treatment progress, including:
  • Joint Vibration Analysis (JVA)
  • Jaw Tracking (JT)
  • Electromyography (EMG)
  • BioTENS and BioPAK Bite Registration
  • T-Scan II
  • Radiographs

Joint Vibration Analysis (JVA)

This equipment (approved by the ADA) measures how well the TMJ functions while in motion. This is accomplished by placing headphones over the joints and recording the vibrations of either soft tissue or bone-on-bone grinding. Dr. Rawson feels this device is mandatory when determining what position the mandible (lower jaw bone) should be placed in therapy. This technology also serves as objective proof of what is happening to the joint as it functions and is dramatically less expensive and time consuming than an MRI.

Jaw Tracking (JT)

Also known as electrognathography, this equipment offers the ability to track jaw movements three-dimensionally and record the point of dysfunction, all non-invasively. A headset is placed on the patient. A specialized magnet is placed inside the patient’s lower front teeth. Then a recording of the lower jaw movement is made. This information is vital for identifying the correction needed.

Electromyography (EMG)

This equipment evaluates muscle tension through sensors that are placed over the patient’s head. The information it produces tells Dr. Rawson if the problem is ascending up the spinal cord from below the neck or if it is descending. This information is very important in correcting posture problems that are either the origin or the effect of the TMD. Swallowing, chewing, clenching and bite problems can also be effectively identified using EMG.

BioTENS and BioPAK Bite Registration

This portable equipment helps reduce facial pain for many patients. BioTENS is a compact, ultra-low frequency, electrical neural stimulator that delivers a precisely regulated, rhythmic stimulus to both masticatory and facial muscles. A single pair of electrodes mildly stimulate cranial nerves that affect key muscles in the face, jaw and parts of the neck. This relaxes the muscles, thereby reducing facial pain. BioPAK Bite Registration provides key data on the patient’s different bite relationships which helps Dr. Rawson to better understand the dysfunction that may be causing or contributing to TMD.

T-Scan II

This technology is used to precisely document a patient’s bite (occlusion). A sensor is placed in the patient’s mouth using a special handle. As the patient bites on the ultra thin sensor, the T-Scan II software scans the movement and displays the occlusion on a computer screen. The timing and force of the tooth contacts are shown in color-coded contour images. This information allows for instant diagnosis of occlusion problems.

Radiographs

This imaging technology provides x-rays of the head and neck as well as complex motions and elliptical slices of the head. These images are much more comprehensive than typical dental and cranial x-rays and are useful in determining the precise source of a TMJ problem.
