Temporomandibular joint is the most important joint in our face, which "contracts" various mouth opening actions such as talking and chewing. Temporomandibular joint disorder (TMD) is a common disease in oral and maxillofacial region. Joint disorder is like the defect of the pinion in the rear wheel of a bicycle, which leads to the mismatch between the pinion and the chain and makes the bicycle unstable.

Opening your mouth will bounce, and the longer your face, the more crooked it will be. It's called temporomandibular joint disorder. How many people have this disease?

Once this happens, it is mainly manifested as joint pain, joint bounce and mandibular movement disorder during exercise. Most patients have joint dysfunction, but a few cases have organic changes. Patients will have limited mouth opening, accompanied by temple pain, dizziness, tinnitus and other symptoms.

After a long time, patients may also have asymmetrical faces on both sides, or even a crooked face visible to the naked eye. Second, these factors are easy to cause, please avoid them!

The factors leading to temporomandibular joint disorder are comprehensive and closely related to many bad habits and postures.

1. Mental and neurological factors

Psychological stimulation factors such as nervousness, anxiety and neuroticism will act on the cerebral cortex through the nervous system, and then activate the adrenal medulla and release a large amount of catecholamine, which will lead to a large amount of secretion of adrenaline and norepinephrine, which will lead to muscle spasm, facial pain and stiffness.

2. Behavior habits

One-sided eating in life will lead to bilateral muscle tension imbalance. If you like to eat hard food, it will also lead to excessive chewing and further damage to muscles, ligaments and joints.

In addition, teachers talk too much, parents spend too much time playing musical instruments, singers wait too long to practice their mouths, which will lead to oral joint and ligament damage. Some bad habits, such as grinding teeth at night, biting foreign bodies, and excessive jaw pressure when sleeping. , will cause bad symptoms.

3. Other factors

Traumatic factors hurt the face, which will cause damage to the oral joint area. Oral surgery, tooth extraction, etc. People who keep their mouths open for too long can also cause injuries to muscles, ligaments and joints. Cold weather stimulates facial vascular muscle contraction, which can lead to muscle spasm and pain.

In addition, abnormal development of facial joints, immune or metabolic factors can also lead to diseases.

Third, it is difficult to cure, and self-management is very important.

At present, temporomandibular disorders are usually treated conservatively, with daily care, changing bad habits, relieving and improving symptoms as the key.

First of all, we should correct bad habits. Don't chew hard food for a long time, avoid chewing one side at the same time, yawn every day, and don't open your mouth too wide to avoid opening your mouth too wide.

Second, keep the position of the joint. Do not chew gum for a long time. At the same time, singers, teachers, actors and other special professional groups. We should pay more attention to our oral cavity in our daily life. Only by maintaining bad oral posture and correct joint position for a long time can the risk of illness be reduced.

Finally, you should learn to relax yourself through proper massage and hot compress. Keep a calm mind, don't be nervous, and don't be too angry, so as not to make the muscles in the mouth tense and stiff.

In addition, proper massage and hot compress can be carried out on the oral area, which is helpful to relieve muscle tension and enhance blood flow in the oral area. Massage the masseter and temporal muscles 2~3 times a day for 5 minutes each time, and the massage effect is better after waking up.

Fourth, if the symptoms are serious, you need treatment.

Clinically, non-steroidal anti-inflammatory drugs, such as glucosamine sulfate, can relieve inflammation and pain, and effectively improve bone and joint inflammation and structure. If the pain is obvious and accompanied by mental symptoms, painkillers and antidepressants can be used under the guidance of a doctor.

In addition to drugs, intra-articular injection, usually sodium hyaluronate injection, can effectively improve the symptoms of joint injury.

In addition, physical therapy methods such as intermediate frequency pulse electrotherapy, shock wave therapy and local infrared radiation are also helpful to relieve symptoms.

If the symptoms are serious and conservative treatment is ineffective, surgery can be considered. Because of the complexity of surgery, the risk of complications and behavioral and psychological disorders, we must be cautious before choosing surgery, which is why many doctors give priority to conservative treatment.

In short, temporomandibular disorders should be analyzed according to the patient's condition and a perfect plan should be formulated according to the indications, so as to achieve good results. Have you learned how to relax your muscles and avoid some stimulating factors?

Temporomandibular joint is a joint with facial rotation and joint movement, and its anatomical characteristics and movement are one of the most complicated joints in human body.

The main function of temporomandibular joint is to participate in chewing, speech, swallowing and expression.

When chewing, the joints should bear pressure; When speaking, singing and expressing, the movement of temporomandibular joint needs to be very flexible.

Can't talk? Be careful, this is temporomandibular joint disorder.

Temporomandibular joint disorder syndrome is mainly manifested as pain in joint area or face, decreased mouth opening, joint murmur, joint lasso adhesion, limited joint function and pain caused by chewing food, which has a high incidence in daily life.

Etiology of temporomandibular disorders;

1. Mental and psychological factors:

With the acceleration of the pace of life in modern society and the increase of various pressures, many staff members lack rest and have psychological factors such as depression, anxiety and mental stress, which often lead to temporomandibular joint disorder.

2. Malocclusion:

Bad dentures, missing molars, etc. , make the internal structure of the joint out of balance.

3. Traumatic factors:

Grinding teeth at night, like biting hard objects, leading to excessive joint load and long-term unilateral chewing habits. Fighting with people hurts the face, leading to joint strain and masticatory muscle dysfunction.

4. Other factors:

Systemic diseases such as rheumatoid arthritis. In addition, some iatrogenic factors, such as radiotherapy for nasopharyngeal carcinoma, will lead to changes in the structure and function of masticatory muscles.

Temporomandibular joint disorder syndrome has three clinical features:

1. Abnormal jaw movement-unable to open mouth.

2. Joint bounce noise-the sound of the temporomandibular joint can be heard by yourself with your mouth open.

3. Pain-When you open your mouth or bite something, the pain will get worse, and biting something hard will make it more painful.
