Temporomandibular Joint Disorder (TMJ) treatment aims to alleviate pain, restore joint function, and improve patients' quality of life. The treatment approach varies depending on the severity of symptoms and underlying causes, potentially including medication, physical therapy, intraoral appliances, or surgery. The primary goal is to prevent disease progression and to gradually intervene through non-invasive to invasive treatments.
1. Medication: Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit prostaglandin synthesis, reducing inflammation and pain. Muscle relaxants are used to relieve tension in the masticatory muscles. 2. Physical Therapy: Heat therapy or ultrasound can promote local blood flow, and traction exercises help restore joint mobility. 3. Intraoral Appliances: Occlusal splints adjust bite alignment to reduce joint pressure and prevent bruxism behaviors.
Suitable for symptoms such as TMJ pain, limited mouth opening, or joint sounds. Common causes include disc displacement, degenerative joint disease, trauma, or malocclusion. Also applicable for muscle fatigue or joint structural damage caused by long-term bruxism.
Medication is usually recommended at 2-3 times daily for NSAIDs, with total daily doses not exceeding safety limits. Custom-made intraoral appliances should be fitted by a dentist, recommended for use 5-7 days per week, with periodic shape adjustments during use. Surgical treatments are mainly for disc repair or arthroscopic debridement, requiring hospitalization for 24-48 hours.
Medication may cause gastrointestinal discomfort or bleeding tendencies; long-term use requires monitoring liver and kidney functions. Intraoral appliances may lead to increased saliva production or tooth movement initially, requiring adjustments every 3-6 months. Surgical risks include infection, nerve damage, or joint stiffness, with an incidence of approximately 3-5%.
Patients with severe liver or kidney disease should avoid high-dose NSAIDs. Prior to fitting intraoral appliances, exclude periodontal disease or severe malocclusion. Pregnant women should use medications under medical supervision. Physical therapy is contraindicated during acute joint infections.
Combining NSAIDs with anticoagulants may increase bleeding risk. When physical therapy is combined with medication, attention should be paid to cumulative drug doses. Patients on biologic therapy should discontinue medication at least 2 weeks prior to surgery to reduce infection risk.
Systematic reviews show that integrated conservative treatment can improve symptoms in 75% of patients within 3-6 months. Arthroscopic surgery has a success rate of about 85%, but recurrence rates are around 10-15%. Biofeedback therapy has demonstrated significant long-term pain management benefits in clinical trials.
Alternatives include acupuncture stimulating auricular points to improve local circulation, or botulinum toxin injections to relieve muscle spasms. Intra-articular steroid injections can provide short-term control of severe inflammation but should be limited to 2-3 times per year to avoid tissue atrophy. Behavioral therapy combined with positive sleep hygiene can help manage chronic pain.
During treatment, it is recommended to follow a "softer diet" principle, avoiding hard foods or those requiring wide mouth opening, such as nuts, apple chunks, or chewy foods. Foods should be cut into small pieces, steamed or soft-textured meals should be chosen, and chewing should be performed slowly with the molars to reduce joint load. Chewing on the healthy side is advised to distribute pressure, and patients should regularly report dietary adjustments to their therapist.
When using a dental splint, how should I handle gum discomfort or oral ulcers?Initial use of a splint may cause mild discomfort; it is recommended to gradually increase wearing time daily and maintain oral and splint hygiene. If ulcers or persistent pain occur, stop use immediately and consult a physician, as adjustments to the splint or protective padding may be necessary. Rinsing with saline solution and avoiding hot or irritating foods on the affected area are also advised.
How should hot and cold therapy be alternated during physical therapy? What are the differences in treatment goals at different stages?During the acute phase, ice packs (15 minutes per session, 3-4 times daily) should be used to reduce swelling and acute pain; in the chronic phase, warm packs (around 40°C, 20 minutes per session) are used to promote blood circulation and muscle relaxation. Therapists will plan alternating cycles based on joint mobility and muscle tension, and patients should strictly follow instructions to avoid worsening symptoms.
How can behavioral therapy improve TMJ symptoms, considering psychological stress as a trigger?Through "cognitive-behavioral therapy," patients can learn to recognize and modify unconscious habits such as teeth clenching, combined with relaxation training like electromyography biofeedback to reduce muscle tension. Daily deep breathing exercises and joint relaxation routines are recommended, along with keeping a "response diary" to record symptoms and triggers, working with the treatment team to adjust intervention strategies.
What are the key considerations for postoperative recovery following surgery for TMJ?Surgery is typically indicated for severe cases with disc displacement, bony destruction, or failure of conservative treatments. Postoperative care includes strict adherence to a "minimally invasive recovery plan," such as wearing protective splints, avoiding excessive mouth opening, and applying daily ice packs to reduce swelling. For the first three months, avoid wide mouth movements such as yawning or laughing, and regularly assess joint function to adjust rehabilitation plans.
