Enjoy it! Roy's younger brother, who just celebrated his 18 birthday, kept covering his face with a warm baby when the China music bulletin board was exposed. Staff came forward to care. He said that his teeth were misplaced and he giggled when he opened his mouth. It has always been like this. It's more serious today. It's called mandibular dislocation.

In fact, Roy always covers his chin with a warm water bag when shooting Our Youth. Everyone thought Roy was keeping warm before. Now I think Roy should have dislocated by then.

This can make fans feel bad. Roy is a singer, and his favorite thing is singing. If the disease is not cured, it will have a great influence on him!

He suffered too much when he was young. I hope he pays attention to his health!

But the sheep should tell everyone that the probability of this symptom appearing in young people is quite high, and the prevalence rate of women is higher than that of men because of hormones! For everyone's health, let's simply popularize science.

If you open your mouth to eat, it hurts in front of your ears, and it hurts even more when you open your mouth ... When you open your mouth, there is a "click" sound on both sides of your joints, and your face is asymmetrical on both sides, then you may have temporomandibular disorders (looking at the chicken leg in front of you, you suddenly feel a little afraid to eat).

Temporomandibular joint disorders may also affect the muscles of the head, neck and shoulders. Joint pain, masticatory muscle pain, headache, joint murmur and limited mouth opening often occur. In short, I feel pain everywhere. )

Let's first understand what temporomandibular joint is. Temporomandibular joint consists of three parts:

One is the inferior condyle (kē), which is the bone of the chin; One is the articular fossa above. They form a ball-and-socket relationship. Then there is the articular disc in the middle, which is elastic cartilage.

The relationship between ball and socket can be understood as that if you open your left hand and your right hand becomes a fist, then your right fist is wrapped by your left hand with an elastic cartilage in the middle, which is probably the relationship.

When you open your mouth, joints include rotation and sliding.

When the mouth is small, it mainly rotates.

When the mouth is big, it will slide. Especially when the mouth is large, the forward sliding displacement is greater. When the condyle slides forward above the articular tubercle, it is in an unstable position, and the articular capsule is elongated and loosened, but it is not broken.

However, if the mandible is impacted by external force, or the spasm of lateral pterygoid muscle and masseter muscle and the tension of mandibular ligament can push the mandible to slide forward, when the displacement of condyle exceeds the peak of articular tubercle, it can not return to mandibular fossa and slide to articular tubercle again, that is, temporomandibular joint dislocation is formed.

There are many bad habits, which are particularly easy to cause this disease. Babies should pay special attention.

I like to eat hard food and often chew one side when eating. Temporomandibular joint is a load-bearing joint. Every time you chew, especially biting hard objects, it will cause slight wear. But over time, it will increase the load of joints and induce diseases.

Unilateral chewing can also cause facial asymmetry.

In addition to the disorder of temporomandibular joint, the masseter muscle will increase, the mandibular angle will become larger and larger, and the face will become more and more square. ...

Therefore, during the development period, we should not exercise the masseter muscle excessively. After all, no one wants to grow to a low mandibular angle. If the masseter muscles are well developed, you can use botulinum toxin injection to remove the extra muscles in your cheeks.

Always grit your teeth, grind your teeth, etc. The movement of mandible is controlled by the movement of masticatory muscles. If the upper and lower teeth keep in contact all the time, there will be joint movement disorders, and many a mickle makes a mickle, which will induce this disease.

Bad posture, such as working at a desk for a long time, typing, answering the phone frequently and other incorrect postures; Driving in an incorrect head-back posture for a long time will lead to muscle dysfunction in the neck and back and affect the correct position of the mandible. (Sheep who often type are a little flustered.)

Occupational disease. For example: teachers, performers, singers. Basically, if you need to talk often and use your mouth, it is easy to get this disease. I feel bad for Roy's brother again.

Psychological factors. Nervous, anxious and depressed. In fact, many diseases are caused by psychological reasons. If you feel uncomfortable and your resistance drops, you are particularly prone to illness.

Being a man, the most important thing is to be happy!

There are many reasons for temporomandibular joint disorder. It is not a disease, but a general term for a class of diseases with the same symptoms. According to the main causes, temporomandibular disorders can be divided into four categories:

Disorder of masticatory muscles. In layman's terms, the muscles that pull the mandible are spasmodic, and they are not forced or out of control. The disorder of joint structure is that there is something wrong with the structure of the joint, and the content of the joint is normal but the relative position relationship is problematic. Joint injuries caused by inflammatory diseases and bacterial infections. Osteoarthropathy, there is something wrong with the contents of the joint. Therefore, to choose treatment according to the etiology, we must first make a clear diagnosis. Symptomatic treatment of temporomandibular disorders mainly includes physical therapy, (laser, electrical stimulation) drug therapy, intra-articular injection therapy and muscle block therapy.

I feel that it is really difficult to have a healthy and perfect mandible … I am tired.

Dysplasia is prone to all kinds of protruding mouth, covering the sky, chin retraction, nose depression and Chinese character face. ...

For example, Nana Ou-yang had a prominent mouth when he was a child. It is accompanied by mandibular hypoplasia such as chin retraction and short mandible.

If it is a serious oral process, you can only choose bone transfer (orthognathic) surgery to solve this problem in adulthood ... If you have severe chin retraction, you need mandibular treatment or chin enlargement.

The ground covers the sky, the face is concave and wide, and the side is like the moon. If you miss the development stage and want to correct this problem after all the bones are set, you can only move the bones. ...

If babies have jaw problems (such as floor covering, protruding mouth, and lower jaw retraction), the sooner the better. In the growth and development period, non-surgical methods combined with growth and development improvement can achieve good results. In adulthood, most of them can only rely on orthognathic surgery.
