TMD Testing

A proper diagnosis always begins with a thorough examination by Dr. Tregaskes. The clinical exam involves a detailed medical-dental history with specific questions about the symptoms, nature, and duration of jaw problems. You will be given ample one on one time with Dr. Tregaskes to make sure that all of your problems are addressed.

Joint Vibration Analysis

TM Joint Vibration Analysis is a quick, non-invasive method for your dentist to examine how your jaw joints function. The vibration from each patient is like your own personal signature - determined by loudness, duration and frequency.

Our office uses a new device called Joint Vibration Analysis (JVA) to help determine if patients have a TM joint (jaw joint) problem. Joint Vibration Analysis has the acceptance of the American Dental Association. The dentist has the primary responsibility for diagnosing disorders of this particular joint. Utilizing the JVA procedure aids the dentist in making an accurate diagnosis and demonstrates the severity level of the disorder.


Evaluation of the patterns of jaw movement during normal opening and closing chewing, swallowing and speech. These measurements are taken through the application of a small magnet to the lower front teeth and detecting sensor arrays.

By combining the Jaw Tracker (JT) and the JVA we are able to record the lower jaw movements and TMJ functionally, which produces enormous amounts of diagnostic information. Jaw Tracking is a completely non-invasive procedure as all that it involves is placing a headset on the patient and affixing a small magnet to the lower front teeth.


Evaluation of muscle activity both at rest and during function by application of surface pads located over the muscles that operate the jaw. These pads tell the practitioner the level of function or dysfunction within the muscle.

i-CAT Cone Beam 3D Imaging

At your first appointment as a new TMD patient, we’ll complete a quick CBCT of your head and neck to get a precise view of your jaw joints. Another more extensive scan may be needed later in your treatment to rule out problems with your airway, sinuses, cervical spine, etc. …The i-CAT is also great for implant and surgical planning. Many times Dr. Tregaskes will send your scan to a radiologist simply to double check for any abnormalities that may have been overlooked.
