Diagnosis of TMJ

Depending on the nature and severity of the problem, the evaluation of hard tissues may be accomplished using x-rays and CT scans. Soft tissue is evaluated using MRI’s, Joint Vibration Analysis (JVA) and electromyography (EMG). Jaw movements are documented using the Jaw Tracker (JT). Occlusion is evaluated using the T-Scan.

The evaluation process will include:

Detailed Medical and Dental History

A complete medical history must be documented, including all past medical and/or dental problems and treatments, any history of trauma (especially to the head and neck region), specific questions about your symptoms, the nature and duration of any pain and jaw problems.

Physical Examination

A complete physical examination for a TMJ problem will likely include:

1. Postural exam to discover any musculoskeletal problems that either contribute to or are the result of TMJ problems. This includes scoliosis, lower back pain and short leg syndrome, among others.
2. A cranial examination to evaluate the planes of the skull, including the alignment of the jaw joints and mouth to the rest of the body (dental plane of occlusion).
3. Dental examination to evaluate the shape of the dental arches, swallowing patterns, tooth wear or fractures, missing teeth, existing dental restorations or other clues. The dentist will usually make models of the mouth so the teeth and dental arches can be more closely examined.
4. Neurologic examination to test for nerve or brain damage that may cause TMJ symptoms.
5. TMJ examination to look at the ranges of motion, gait, speed and smoothness of jaw movement. Additionally, the TM joints will be checked for internal joint inflammation, pain and the presence of joint sounds.
6. Joint Vibrational Analysis, a non-invasive technology that records the vibrations made by joint tissues during movement. The patterns and electronic signature of the patient’s joints are compared with known standards for healthy joints, providing objective proof of a TMD.
