Study Notes
Treatment for TMJ Disorders
- Treatment options include exercises, application of heat, and medications for pain relief and muscle relaxation.
- Botulinum toxin (Botox) can be administered to alleviate symptoms.
- Patients are often advised to follow a soft diet to reduce strain on the jaw.
- Dental professionals, including general dentists and oral surgeons, may recommend bite guards or splints.
- Sudden changes in how teeth fit together may signal TMJ issues that warrant intervention.
- Surgical options include arthroscopy, arthrocentesis, joint surgery, or joint replacement, depending on severity.
Symptoms of TMJ Disorders
- Common symptoms include headaches resembling migraines, earaches, and pressure behind the eyes.
- Clicking or popping sounds may occur during mouth movement.
- Pain can be triggered by yawning, wide mouth opening, or chewing.
- Symptoms may also include jaw locking, tenderness in jaw muscles, and limited mouth opening (trismus).
Disorders of the TMJ
- Temporomandibular disorders (TMD) are categorized into three main types:
- Myofascial pain: The most prevalent form, involving pain in jaw and neck muscles.
- Internal derangement: Includes conditions such as dislocated jaw, displaced disc, or injuries to the condyle.
- Degenerative joint disease: Conditions like osteoarthritis or rheumatoid arthritis affecting the jaw.
Movements of the Mandible
- The opening of the jaw begins with the rotation of the condyle within the glenoid fossa.
- Mandibular movements include:
- Rotational movement around the horizontal axis (hinge axis).
- Vertical movement around the frontal axis.
- Sagittal axis movements, facilitating various jaw functions.
Trismus
- Trismus is characterized by the inability to open the mouth more than 35 millimeters.
- Causes include jaw trauma, oral surgery, infections, cancers, or radiation therapy for head and neck cancers.
- It is often a postoperative complication following lengthy dental procedures or local anesthetic applications.
- Trismus can be either temporary or permanent, necessitating specific management strategies.
