Description

  The present invention relates to a mandibular position correction training tool that is attached to the inside of an oral cavity to perform correction training of a mandibular position.

The so-called malocclusions in which the upper and lower dentitions are malformed include so-called alveolar ones resulting from malalignment of teeth, upper and lower jaws, and irregular dentitions. There are so-called functional ones, and so-called skeletal ones that are vertical / anteroposterior frauds that are not reduced even in a resting position.
In particular, skeletal irregularities have been the subject of surgical treatment.
The malocclusion as described above is one of the factors that cause various symptoms such as temporomandibular disorders, opening disorders, dysphagia, and periodontal diseases.
In so-called opposite occlusion, which is one of the cases of skeletal malformation, the positional relationship of the lower jaw with respect to the upper jaw (occlusion position) at the time of occlusion is largely related to the position of the tongue in the oral cavity and the strength of the upper lip pressure.
For example, when the upper lip pressure is large, the upper jaw is guided backward, and when the tongue is in a low position, the mouth tends to remain open, and the force that pushes the lower jaw forward by the tongue acts. To do.
Therefore, when the state as described above continues, the lower jaw protrudes forward from the upper jaw (mandibular front protrusion), causing malocclusion in which the lower tooth row is positioned forward of the upper tooth row.

As an instrument for treating the above skeletal malocclusion, an acrylic resin called activator, which is detachably attached to the inside of the oral cavity and is formed so as to cover the upper and lower dentitions from the side of the tongue and the occlusal surface. Straighteners are used.
The orthodontic tool collects a tooth mold with a mold material made of paraffin or the like, which is referred to as bite wax in advance, and produces a tooth model based on the collected tooth mold.
Furthermore, the form and structure applied to a case are designed and manufactured based on this tooth model.
The above dental model is difficult to produce in dentistry, and is produced by a professional engineer with skilled skills, so it takes a long time to complete the orthodontic appliance after collecting the dental mold in dentistry. In addition to being necessary, each patient is made-to-order, so there are problems such as a large number of work steps and an increase in the cost of manufacturing the correction tool.
