My father grinds his teeth at night. When he grinds his teeth, he will stand up and walk around. He always touches his whole body with his hands. Man seems to be awake because his eyes are open.

Sleep molar is the abnormal excitement of some brain cells in the cortical and mandibular motor area of the central nervous system, which leads to the dysfunction of trigeminal nerve, and the trigeminal nerve dominates the masticatory muscles for strong and continuous non-functional contraction, making teeth rattle. The so-called bruxism refers to those who habitually grind their teeth during sleep or unconsciously grind their teeth during the day. This is a long-term vicious circle disease ... generally divided into three types:

① Molar type: People often grind their teeth after falling asleep at night, which is often called night grinding. During sleep, patients grind their teeth or clench their teeth, which is often called "grinding teeth" because of grinding their teeth. Also, it is also called "night grinding" because it mostly happens during sleep at night. Patients don't know it themselves, and it is often said by others that it is more valued because it affects others, especially their spouses.

② Occlusal type: During the daytime, the teeth often clench unconsciously, but the upper and lower teeth do not grind.

③ Mixed type: There is the phenomenon of grinding teeth at night and grinding teeth during the day.

There are six main reasons:

(1) Psychological factors such as nervousness, psychological anxiety, depression and anger;

(2) Gastrointestinal diseases and endocrine disorders can also lead to this;

(3) Those who are excessively tired and engaged in fine labor, such as athletes and clockmakers;

(4) Lack of trace elements in the body is prone to this disease, and there are parasites in the body.

(5) Habitual bruxism caused by long-term molars;

(6) Work pressure, physical fatigue, and irregular life for a long time lead to grinding teeth!

In addition to the above people, people who are introverted, emotional and often bite in their mouths are also prone to bruxism.

therapeutic method

There are many ways to treat bruxism. The main clinical purpose is to reduce the damage of molars to the occlusal surface of teeth and relieve the symptoms of muscle joints. The principle is to block the cause and reduce the harm.

1) psychotherapy: there are indeed mental and psychological factors that make the mandibular muscles excessively tense. Eliminate nervousness, eliminate unnecessary worries and arrange work reasonably. If necessary, take diazepam orally, 1-2 times a day, 1 time, each time 1 tablet. Have dependence.

2) Treatment to reduce brain excitement: relaxing before going to bed, doing proper gymnastics, avoiding irritating food and smoking, and improving the sleeping environment are all conducive to reducing brain excitement. Mobilize patients' psychological functions of self-awareness and self-control to reduce the occurrence of molars. The impact is not great.

3) Muscle relaxation therapy: excessive mandibular muscle tension is one of the causes of bruxism, and relieving excessive muscle tension during treatment is a necessary means to control bruxism. The commonly used methods are: using muscle relaxation instrument; Physical therapy, training the physiological function of masticatory muscles; Massage; Audio-visual suggestion and other methods. The impact is not great.

4) Treatment of wake-up stimulation during sleep: Through biofeedback, patients are awakened by electrical signals such as sound when grinding their teeth, thus temporarily stopping grinding their teeth. Some scholars apply temporary afferent electrical stimulation to lips, which is effective in controlling bruxism. But this method interferes with the sleep of patients and cohabitants, and the effect is not long-term.

5) Adjustment of occlusal treatment: By adjusting and polishing a small amount of tooth tissue, the occlusal interference and early occlusal contact can be relieved, and the occlusal balance relationship can be established, so as to achieve the physiological balance between jaw, masticatory muscles and temporomandibular joint and eliminate bruxism. For patients with malocclusion, orthodontics or repair should be carried out first. Then take Muyating capsule to regulate nerves and get rid of bruxism.

6) Intestinal anthelmintic treatment: Ascaris killing treatment can reduce the peristalsis of intestinal parasites and stimulate the intestinal wall. Nocturnal molars caused by ascaris lumbricoides may occur in childhood due to hygienic reasons, but nocturia caused by ascaris lumbricoides hardly exists in adolescence and adulthood. Therefore, anthelmintic treatment has no effect on adolescents and adults.

7) Treatment of occlusal plate: make a dental pad, put it on the teeth and jaw before going to bed at night, and take it off in the morning to relieve muscle tension. At present, it is most easily accepted by doctors and patients, and the effect of preventing tooth wear is obvious, but it cannot treat bruxism.

8) Correct the bad habits of oral system. Such as unilateral chewing, pencil biting, chewing gum, etc.

Patients with severe night molars should take active treatment measures, start with the causes, pay attention to adjusting their psychology and relieve their pressure. It is best to rest and relax before going to bed, avoid irritating food and improve the sleeping environment. We should also actively treat systemic diseases and reduce the occurrence of night molars.

For bruxism with occlusion as the main factor, it is necessary to go to the hospital stomatology department for treatment, and remove occlusal interference by grinding the early contact points of teeth. Patients with missing teeth should take measures such as denture restoration and changing unilateral chewing habits to achieve occlusal balance.

If the teeth are badly worn, it is recommended to use occlusal pad for partition to avoid further tooth wear. Patients can't buy it by themselves, so they need to wear it under the guidance of a doctor.
