The bending of the attached archwire adds a sustained load to the alveolar bone supporting the teeth. Bone resorption occurs in the portion where the alveolar bone is pressed by the load, and bone addition occurs in the portion where the alveolar bone is towed, and the alveolar bone is remodeled. As a result, the teeth move.
- the teeth belonging to the front teeth or the lateral teeth are moved in the desired direction, thereby adjusting the teeth (occlusal) between the dentition and the teeth.
- an MB device has a complex shape consisting of many brackets and arch wires.
- a part of the MB device comes into contact with the mouth and causes discomfort to the lips.
- Short-term wearing can be tolerated to some extent, but long-term discomfort of around two years can cause significant pain for the patient.

- the orthodontic mouthpiece be worn at any convenient time and at least about one hour a day. They can be worn at bedtime.
- the orthodontic mouthpiece of the present invention can be easily removed, and the wearing time is much shorter than that of a conventional MB device.For example, it is possible to wear the TV at home while watching the TV. Patients can continue home treatment without burdening time.
- the first half orthodontic mouthpiece A1 may be worn several times a day, but it is not necessary to use the ultrasonic stimulator every time.
- the dentition is guided to the groove of the first half orthodontic mouthpiece A1, and the teeth to be corrected are sequentially moved.
- check the progress of the orthodontic treatment adjust the orthodontic linear member of the position adjustment means, and reattach the orthodontic mouthpiece and continue the home with ultrasonic irradiation again .
- the dentition leveling stage will be completed.
- the second half orthodontics The orthodontic linear member of the orthodontic mouthpiece A2 is adjusted and attached to the patient's mouth, and at the same time, ultrasonic waves are emitted from the outside of the mouth to the gingival equivalent parts of the front teeth and the left and right lateral teeth.
- the wearing time of the mouthpiece A2 for the second half orthodontics may be the same as that of the mouthpiece A1 for the first half orthodontics, and the ultrasonic irradiation may be performed in the same manner.
- the orthodontic treatment having the above-described structure created by the present inventor is an excellent orthodontic treatment in a very short time and with a very small burden on patients, which could not be predicted from conventional techniques.
- the orthodontic treatment using the ultrasonic stimulator and the orthodontic mouthpiece described in the first embodiment is described.
- the wave stimulus supply unit such as the ultrasonic stimulator is used in combination.
- the orthodontic treatment effect can be obtained even if the orthodontic mouthpiece of the present invention is used alone without performing the procedure.
- corrective treatment can be performed by dividing the process from the start of treatment to the end of treatment into a plurality of treatment stages according to the progress of the treatment, and appropriately using a correction mouthpiece configured for each treatment stage. How to set the treatment stage can be determined according to the individual patient.
- the treatment stage is divided into multiple treatment stages from the start of treatment to the end of treatment, and multiple mouthpieces for the first half orthodontics and mouthpieces for the second half orthodontics are manufactured and treated accordingly. It does not matter.
- a correction mouthpiece instead of manufacturing a correction mouthpiece each time according to the treatment stage, several treatment stages are set in advance, and a ready-made correction mouse corresponding to that is set.
- the tongue protruding habit and force to unconsciously sandwich the tongue between the upper and lower teeth when swallowing the bite lip habit of the lower lip, the so-called muscle function therapy (MF T) that cures routine tongue and lip habits
- MF T muscle function therapy
- the so-called treatment may be used in combination with the orthodontic mouthpiece of the present invention.
- the present invention is not limited to the above-described embodiment, and may be variously modified without departing from the gist of the present invention.
- the stage of the orthodontic treatment is roughly divided into two and the two kinds of mouthpieces for orthodontic treatment are prepared is described. Three or more kinds of mouthpieces may be used.
- the correction linear member provided with the loop portion in the middle is used as the position adjusting means, but an adjusting means other than such a configuration may be adopted.
- any means other than the linear member may be used as long as it is made of a material that is safe even when it is put into the mouth, and can adjust the position of the correction guide part as desired.
- the application of a straightening screw or the like can be considered.
- the treatment may be performed by sequentially using the above-mentioned mouthpieces for orthodontics.
- silicone rubber with high elasticity was used.However, if the contact stimulus to the oral mucosa is soft and the surface is smooth, any material other than silicone wrapper, such as sports, is used. It may be formed of various elastic materials for mouth guard. It does not specify any material.
- the gingiva may be directly irradiated by an intraoral professional.
- the ultrasonic stimulating device is used as the wave stimulating device that provides the wave energy that contributes to the movement of the tooth to be corrected.
- any device that provides the wave energy other than the ultrasonic wave may be used. Absent.
- the mouthpiece for orthodontics of the present invention can be applied to not only orthodontic treatment but also, for example, jaw surgery or a fixation device for jaw bone fracture.
- the use of the orthodontic device of the present invention using the orthodontic mouthpiece can also be applied to jaw surgery or treatment for promoting treatment of jaw fractures by ultrasonic stimulation.
- the orthodontic guide part corresponding to each dentition part is formed in an integral non-divided type, the orthodontic treatment corresponding to each dentition part at the time of simple orthodontic treatment of incorrect dentition.
- the orthodontic guide section is divided into segments, it is easy to use without excessive functions.
- there is no need for a means for adjusting the separation distance between the segments and it is possible to further reduce the sense of discomfort when worn in the oral cavity.
- the use of a mouthpiece that is formed in conformity with the predicted dentition model makes it possible to relatively easily form an ideal dentition as compared with the related art.
- a synergistic effect with activation based on an increase in blood flow at an orthodontic site and its surrounding living tissue by intermittent use of wave energy rather than continuous load is expected. Therefore, the tooth can be moved with a much smaller load than a conventional orthodontic appliance.
- the load applied to the dentition is much smaller than that of the conventional orthodontic device, the physical burden such as pain around the dentition and injuries in the mouth due to the treatment is reduced, and the tooth root is reduced. Side effects such as absorption can also be reduced.
