Bio-feedback instrument for bruxism

Abstract

The invention discloses a bio-feedback instrument for bruxism, comprising an occlusal splint and a molar monitor, wherein the canine position on the occlusal splint is heightened to form a lateral tongue pit state; canine protection and induction action on the mandible movement by the canine are utilized; a sensor is embedded into the canine position of the occlusal splint; a molar signal is connected with a signal socket connector in the molar monitor by the signal output end of the sensor; and the signal output end of the signal socket connector is connected with the signal input end of the control chip in the molar monitor. The bio-feedback instrument for bruxism can automatically measure and record accurate data, such as molar time, molar data and the like, accelerate various awakening or reminding music and vibration according to the data of a monitoring record, cause patients to consciously stop the behavior of molar, obtain the bio-feedback effect, treat the bruxism, and objectively evaluate the treatment effect on the bruxism by the instrument. The instrument is small, delicate, and convenient to use, and is applied for treating patients with bruxism with stable curative effect.

Description

technical field [0001] The invention relates to a biofeedback treatment instrument for bruxism, which is used for treating bruxism. It belongs to the technical field of medical equipment. Background technique [0002] Bruxism (bruxism) refers to non-physiological function of teeth grinding or clenching, and is an abnormal functional movement of the masticatory system. The clenching of the teeth is a static contact state of the upper and lower teeth in the centric or non-central position; while grinding is the dynamic contact state of the upper and lower teeth when the mandible moves to various sides. Teeth grinding after falling asleep at night is called bruxism, which is the most common type of bruxism. Bruxism can cause serious tooth wear, dentin hypersensitivity, or pulp damage. In severe cases, it may be accompanied by headaches, masticatory muscle fatigue and soreness, and temporomandibular joint disorders. The sound of grinding teeth also seriously disturbs the rest ...

AI Technical Summary

Problems solved by technology

This method also has obvious shortcomings: EMG biofeedback is to place electrodes on the skin on the surface of the patient's masticatory muscles, swallowing, turning over, sucking and other actions in the sleep state may have certain maxillofacial myoelectric responses, which will interfere with the recording accuracy so that patients are likely to be aroused even when they are not grinding their teeth

This method can directly obtain molar information from the mouth, and overcomes the characteristics of the surface electrode recording that is susceptible to interference in the EMG biofeedback method. However, the smell of onion and garlic juice is too strong, which may not be acceptable to the patient, and it is very uncomfortable to rinse the mouth immediately after waking up. convenient
