Temporomandibular Joint Disorders

TMJ Disorders

— can cause pain in your jaw joint and in the muscles that control jaw movement. The exact cause of a person’s TMJ disorder is often difficult to determine. Your pain may be due to a combination of factors, such as genetics, arthritis, or jaw injury. Some people who have jaw pain also tend to clench or grind their teeth (bruxism), although many people habitually clench or grind their teeth and never develop TMJ disorders?

Physical therapy. Along with exercises to stretch and strengthen jaw muscles, treatments might include ultrasound, moist heat, and ice.
3] Surgical or other procedures
-Arthrocentesis for TMJ
-Injections. In some people, corticosteroid injections into the joint may be helpful. Infrequently, injecting botulinum toxin type A (Botox, others) into the jaw muscles used for chewing may relieve pain associated with TMJ disorders.


TMJ Arthroscopy.

Modified condylotomy. Modified condylotomy (kon-dih-LOT-uh-mee) addresses the TMJ indirectly, with surgery on the mandible, but not in the joint itself. It may be helpful for the treatment of pain and if locking is experienced. -Open-joint surgery. If your jaw pain does not resolve with more-conservative treatments and it appears to be caused by a structural problem in the joint, your doctor or dentist may suggest open-joint surgery (arthrotomy) to repair or replace the joint.
