The Temporomandibular Joint (TMJ) is the joint that connects the temporal bone of the skull to the lower jaw (mandible). This joint is a complex system made of bones, ligaments, muscles, nerves, vessels, and cartilage. All of these function together in harmony in a healthy TMJ. The joint goes through changes to allow the patient to load (chew with pressure), open wide (during yawning), and speak comfortably. When the joint is unhealthy, patients can experience noises (such as clicking, grinding or popping), feel like the jaw is catching or locking, or can suffer from pain or discomfort in or around the TMJ. Patients with unhealthy joint systems can also most commonly experience earaches, headaches, or neck or shoulder pain.
The Dentists at Hillstead Dental take special care to listen to our patients about the symptoms they may be experiencing, examine the radiograph of the joint area, and perform intra- and extra-oral exams to accurately diagnose any dysfunction of the TMJ. These TMJ Disorders (TMDs) can be due to problems in the bones, nerves, muscles, discs, or a combination of the above areas of the joint. A thorough evaluation is necessary for proper treatment and relief.
There are many reasons why a patient may have a disorder in the TMJ. Patients may actually have habits that can cause or contribute to their TMD, such as nighttime clenching or grinding (bruxing). Patients may also be missing some or all of their back teeth which can lead to a change in their bite relationship and an eventual disorder in the joint that has lost the tooth support. Traumatic events, such as automobile accidents or sports injuries, as well as orthodontic or dental changes in the bite can also cause an unhealthy change in the joint.
Our Dentist decides the ideal treatment for patients based upon the evaluation. In most cases, the therapy consists of a custom made TMJ splint to stabilize or re-position the joint. If our Dentists feel that a patients’ jaw is not in the best neuromuscular position, he may recommend TENSing prior to establishing their ideal neuromuscular bite position using advanced computer technology, then an orthodontic is fabricated to allow the patient to retain their harmonious jaw position to eliminate their symptoms. A patient may be assessed on our K-7 computer for a more accurate diagnosis of the muscle activity to allow for the best neuromuscular treatment option for the patient.
