Definitions
- the present invention relates to a bruxism evaluation sheet used in a device that can easily evaluate a tooth contact pattern during sleep bruxism in daily clinical practice, and a liquid dye composition applied to the sheet.
- Sleep bruxism is generally a protective function of daytime and nighttime, including actions such as eating, clenching, grinding, and gnashing teeth. It can be defined as a parafonctional activity. Such sleep bruxism is considered to cause many problems in dentistry (Non-patent Document 1). In the modern diet, excessive tooth wear can no longer occur. This is because there is almost no contact between the upper and lower jaw teeth during modern food chewing. On the other hand, sleep bruxism is reported to be 20 to 40 minutes during an overnight sleep in modern people, and some people may be asking for 2 hours! / Non-patent document 2).
- the maximum occlusal force exerted by the masticatory muscle group during sleep bruxism is much greater than the force required to break the teeth.
- the neuromuscular mechanism is considered to reduce muscle strength under the consciousness and prevent damage to the living body against the load applied to the teeth acutely, while the neurological mechanism under the unconsciousness is the force applied to the enamel and dentin.
- the effect of decreasing the amount is obscene.
- the force exerted by sleep bruxism is considered to be a phenomenon outside the control of the neuromuscular mechanism.
- Such sleep bruxism is caused by many dental diseases such as tooth wear, tooth movement, hypersensitivity, contractual defects, periodontal tissue collapse, temporomandibular joint dysfunction, and masticatory muscle group hypertension. It is thought that a risk of causing the risk is generated (Non-patent Document 3).
- Non-Patent Documents 4 and 5 Bruxism has been proposed (Non-Patent Documents 4 and 5), and it has been suggested that the system of conventional dental occlusion treatment should be fundamentally changed (Non-Patent Document 6).
- Non-patent Documents 7 and 8 Non-patent Documents 7 and 8
- problems such as occlusal collapse were caused by sleep bruxism and abnormal occlusal contact during sleep bruxism, there was a strong method for accurately determining this.
