Temporomandibular joint disorder is one of the common disorders of the oral and maxillofacial region. Among temporomandibular joint disorders, this disease is the most common. It occurs in young adults, with the highest prevalence in the 20s and 30s. Its pathogenesis is not fully understood. The main features of this disease are painful and soreness in the joint area, popping when opening and closing the mouth, and impaired mouth opening movement. Most of the cases are joint dysfunction with good prognosis, but in rare cases, organic changes can occur. For patients suffering from TMJ dysfunction, some habits that aggravate the joint load should be avoided, such as betel nut chewing, gum chewing, pen biting, habitual melon seeds, biting hard objects, finger nail biting, clenching and teeth grinding. These habits are developed by patients in their daily life, such as chewing gum repeatedly, some patients can chew it for a morning, while some patients will clench their teeth when driving, concentrating or nervous, all these aggravate the damage to TMJ. In addition, the regulation of psychology also plays an important role. 1, psychological factors Neuropsychological factors have a certain relationship with the disease. For example, some patients have been in a situation of emotional impatience, nervousness, easily excited, etc. Some patients are also introverted, less communication with the outside world, often sullen. Therefore, all patients should actively regulate the psychological situation, encounter troublesome things to look away, optimistic to face everything, a relaxed state of mind to deal with all life, work and study in the event. 2, avoid cold Clinical studies have shown that clinically cold, such as autumn and winter is indeed a high incidence of TMJ disease, even in the summer, a long time blowing air conditioning fans, there are also patients with the onset of the disease. Therefore, it is recommended to pay attention to local warmth and avoid cold, especially for patients with rheumatic diseases. 3, try to maintain the correct position of the jaw Also known as the mandibular resting position of the lower jaw. In this state, the tongue is required to be fully relaxed, the front third of the tongue should be in gentle contact with the upper wall of the mouth, and the upper and lower teeth are separated by 2-3 mm. some patients may ask: how long does this position need to be maintained? This is the position or posture that the mandible holds at normal rest, which means that the patient needs to try to maintain it all the time outside of eating and sleeping. This is because this is the position where the muscles around the joint are most relaxed and where there is the least amount of pressure within the joint. For patients who are used to clenching their teeth, they can generally get used to it gradually after a month of adaptation. 4, pay attention to the way of breathing Try to avoid mouth breathing, strive to breathe through the nose when the upper and lower lips gently closed. 5.When singing karaoke and yawning, the tongue should be held against the upper jaw to avoid opening the mouth wide For this “yawning” way”, many patients will feel that it is not “cool” enough, but opening the mouth wide itself is the damage to our joints. For example, many patients are unable to close their mouths when they open them wide, which is known as temporomandibular joint dislocation. These are behaviors that can damage the joints. 6, pay attention to adjust the sleeping posture and daily bad posture Avoid sleeping on your stomach. Sleeping on your stomach will press on our TMJ, which will invariably increase the burden on the joint. At the same time, it is also recommended that you do not use your hands to hold your chin when resting. 7. Chewing method Be sure to chew bilaterally and eat in a balanced way: when eating, try to chew on both sides at the same time, so that the force on both sides of the jaw is even, which is conducive to maintaining the good function of the joint. 8, the nature of food and TMJ disease patients Eat soft food, do not eat nuts or difficult to bite food. For example, sugar cane, small walnuts, etc., should be avoided to bite directly with the mouth. For more serious patients, it is recommended to cut the food into small pieces for consumption. 9, warm water gargle and bilateral preauricular hot compresses In many cases, patients with TMJ disorder have muscle problems. Warm water gargle and bilateral preauricular hot compresses with warm water bags are good for relaxing our chewing muscles. 10.When carrying out oral treatment, certain treatment methods may lead to the emergence of TMJ disorder Such as dental treatment, treating many teeth at one time, resulting in too long an opening time or using a bone chisel to vigorously divide the teeth, external force affects TMJ. or a longer period of over-open mouth may lead to TMJ disorder. The term habit refers to a lifestyle that has been developed over time. One study showed that changing or maintaining a certain lifestyle for 21 days changed or developed a certain habit.
