The treatment principle of teeth grinding is to reduce the damage brought by teeth grinding to the occlusal surface of the teeth, reduce the symptoms of muscles and joints, block the cause of the disease, and reduce the damage. At present, there are five types of commonly used treatment methods, as follows: 1, behavioral medicine model, including psychotherapy, muscle relaxation therapy, psychological tension leading to muscle tension is a common cause of disease, eliminate stress factors, lifting unnecessary concerns, appropriate stress reduction, reasonable arrangement of work, relaxation before going to bed, do the appropriate exercise, avoid taking excitatory foods, improve the sleep environment and other measures are conducive to reducing the excitatory state of the brain, mobilize the patient’s self-consciousness, self-control ability, reduce teeth grinding disorder. All these measures can help to reduce the excitation state of the brain, mobilize the patient’s self-awareness and self-control ability, and reduce the occurrence of teeth grinding disorder. Muscle relaxation includes the use of muscle relaxation instrument, body therapy, massage and other methods have a certain effect; 2, biofeedback therapy, through biofeedback to the patient to install electronic equipment, so that the patient in the occurrence of teeth grinding by the sound of electrical signals such as waking up, so as to temporarily stop grinding teeth; 3, jaw treatment, including jaw adjustment therapy and the use of bite plate, jaw adjustment therapy refers to the adjustment of a small amount of dental tissues by grinding to remove the interference of occlusion to establish a balanced dental relationship, in order to achieve teeth grinding. Balanced dental relationship, in order to achieve the physiological balance between the teeth, muscles, temporomandibular joints, jawbone, and eliminate teeth grinding. For orthodontic restoration or orthognathic surgery, orthodontic surgery, occlusal plate treatment refers to the production of occlusal plates, worn on the teeth before going to bed, and removed in the morning, to relieve muscle tension and protect the teeth loss during teeth grinding, which is currently the most easily accepted by the patients, but does not cure teeth grinding syndrome; 4, change the bad habits, when a person sits upright or sitting upright, with both eyes flatly staring straight ahead, does not chew, does not swallow, does not speak, and the lower jaw When people sit upright or upright, without chewing, swallowing or talking, the lower jaw is in a resting state, and when the upper and lower teeth are not in contact with each other, the position of the lower jaw is the mandibular posture position, and it can be alleviated to varying degrees by maintaining the mandibular posture position and resting the muscles and mandibular joints, and the patients should correct the bad habits of chewing on one side, chewing on pencils and chewing betel nuts. Within four weeks after the injection, some patients will start to reduce or stop grinding their teeth, but a few patients will have difficulty in opening their mouths or swallowing. The use of dopamine can regulate the central nervous system, which can significantly reduce the frequency of teeth grinding, but it is prone to cause nausea, vomiting, insomnia, cardiac arrhythmia, psychotic episodes, etc. The use of dopamine is usually only effective when other treatments fail. Medication for teeth grinding is usually only considered when other treatments are ineffective, such as intestinal parasitic infections, gastrointestinal tract dysfunction, endocrine imbalance, allergies, vitamin D deficiency, food retention in children, dyspepsia, and other disorders, which can be treated with targeted medications to remove the possible causes of teeth grinding and also have some efficacy.
