Description

The present invention relates to a training method for improving the function of the muscles around the oral cavity, such as the lips, tongue, and jaw.

Social interest in sleep apnea syndrome (SAS) is growing. The Apnea Hypopnea Index (AHI) indicates the total number of "apneas" and "hypopneas" per hour of sleep, and the severity of SAS is classified according to this index. Recent studies have shown that by improving the function of the muscles around the mouth, such as the lips, tongue, and jaw, AHI can be reduced by approximately 50% in adults and approximately 60% in children.

Traditionally, it has been believed that the cause of abnormal tooth alignment in children (ages 3-15) is genetic. Examples of genetic factors include the size of the teeth and the size of the jaw. However, recent research has shown that the cause of abnormal tooth alignment is not only genetic, but also environmental factors. An example of an environmental factor is dysfunction of the perioral muscles, such as the lips, tongue, and jaw. Dysfunction of the perioral muscles can cause underdevelopment of the upper and lower jaws, which can result in misaligned teeth and pain in the temporomandibular joints and chewing muscles.

The present invention was made in consideration of the above problems, and aims to provide a training method for improving the function of the muscles around the mouth that can cause breathing disorders during sleep, abnormal tooth alignment, temporomandibular joint disorders, etc.

To achieve the above object, the present invention provides a training method for improving the function of the muscles around the oral cavity using a mouthpiece, the mouthpiece comprising a main body having an arch shape that bulges out to one side in a plan view, a tongue tag extending from the main body to the other side, and jaw springs formed at both ends of the main body in a plan view, the training method including a breathing step, a tongue step, a swallowing step, and a lips and cheeks step, the breathing step including nasal breathing, the tongue step including placing the tongue in the correct position, the swallowing step including swallowing correctly, and the lips and cheeks step including using the orbicularis oris muscle (Invention 1).

This invention (Invention 1) can improve the function of the muscles around the mouth, which can cause breathing disorders during sleep, abnormal tooth alignment, temporomandibular joint disorders, etc.

In the above invention (Invention 1), the breathing step may include performing correct nasal breathing, performing nasal breathing while walking, and relieving nasal congestion (Invention 2).

This invention (Invention 2) makes it easier to learn nasal breathing.

In the above inventions (Inventions 1 and 2), the tongue step may include placing the entire tongue on the palate, clicking the tongue, and extending the tongue (Invention 3).

This invention (Invention 3) makes it easier to learn the correct tongue position.

In the above invention (Invention 3), the tongue step may further include protruding the tip of the tongue, opening the tongue sideways, and moving the tongue up and down (Invention 4).

This invention (Invention 4) makes it easier to learn the correct tongue position.

In the above inventions (Inventions 1-4), the swallowing step may include drinking in the correct manner, pulling the mouth to drink, and drinking water by placing the mouthpiece in the mouth (Invention 5).

This invention (Invention 5) makes it easier to learn to swallow correctly.

In the above invention (Invention 5), the swallowing step may further include drinking water without placing the mouthpiece in the mouth and holding the water on the tongue (Invention 6).

This invention (Invention 6) makes it easier to learn to swallow correctly.

In the above inventions (Inventions 1-6), the lip and cheek step may include using the orbicularis oris muscle by wearing an accessory of the mouthpiece, smacking the lips, and puffing the mouth (Invention 7).

This invention (Invention 7) makes it easier to improve insufficient lip closure.

In the above inventions (Inventions 1-7), it is preferable that the breathing step, the tongue step, the swallowing step, and the lips and cheeks step are performed in this order (Invention 8).

According to this invention (Invention 8), improvement of the function of the muscles around the oral cavity can be progressed more smoothly.

The present invention can improve the function of the muscles around the mouth, which can cause breathing disorders during sleep, abnormal tooth alignment, temporomandibular joint disorders, etc.

1A and 1B are schematic diagrams showing a mouthpiece used in a training method according to an embodiment of the present invention, in which (a) is a front perspective view and (b) is a rear perspective view. FIG. 2 is a schematic perspective view showing an accessory member of the mouthpiece of FIG. 1 . FIG. 2 is a flow chart showing an example of a training method according to an embodiment of the present invention.

The following describes an embodiment of the present invention with reference to the drawings. The present invention is not limited to the embodiment described below, and the described embodiment is merely an example for explaining the technical features of the present invention. Furthermore, the shapes and dimensions shown in each drawing are shown merely to facilitate understanding of the contents of the present invention, and do not accurately reflect the actual shapes and dimensions.

[Mouthpiece]
1 is a schematic diagram showing a mouthpiece 10 used in a training method according to an embodiment of the present invention, where (a) is a front perspective view and (b) is a rear perspective view. The mouthpiece 10 includes a main body 1, a tongue tag 2, and a jaw spring 3. The training method is performed using the mouthpiece 10. "The training method is performed using the mouthpiece 10" means that the mouthpiece 10 is worn in the oral cavity for a certain period of time, and then training is performed without wearing the mouthpiece 10 in the oral cavity, and that the mouthpiece 10 is worn in the oral cavity for a certain period of time, and then training is performed with the mouthpiece 10 worn in the oral cavity. The "certain period of time" is typically during sleep.

The main body 1 has an arch shape that bulges out to one side in a plan view. The main body 1 has a protrusion 11 that is provided along the arch shape in the direction opposite to the bulging direction. The protrusion 11 is provided so as to jut out toward the inside of the arch shape of the main body 1. When worn, the protrusion 11 of the main body 1 is positioned between the upper and lower rows of teeth.

The tongue tag 2 is arranged to extend in the opposite direction to the direction in which it bulges out from the main body 1. When worn, the tip of the tongue is placed against the tongue tag 2.

The jaw spring portion 3 is formed on both ends of the main body portion 1 in a plan view. When worn, the jaw spring portion 3 is positioned between the upper and lower jaws.

The mouthpiece 10 is made of an elastic resin material. The elastic resin material is, for example, medical grade silicone.

[Training method using a mouthpiece]
The training method includes a breathing step, a tongue step, a swallowing step, and a lip and cheek step. Each step will be described below.

[Breathing Step]
The breathing step includes breathing through the nose. Breathing through the nose is performed with the mouth closed. Once the person is able to breathe through the nose, the person may proceed to another step. The breathing step is preferably continued for, for example, three months.

The breathing step may include performing correct nasal breathing, performing nasal breathing while walking, and relieving nasal congestion. These three sub-steps are preferably performed in this order. Including these three sub-steps makes it easier to learn nasal breathing. Note that these three sub-steps are performed without placing the mouthpiece 10 in the oral cavity.

(Sub-steps for proper nasal breathing)
The sub-step of correct nasal breathing allows the user to always perform diaphragmatic breathing as a correct breathing method. When performing diaphragmatic breathing, it is preferable to be aware of using the abdomen, not the shoulders or chest. For example, the goal of this sub-step may be to feel the sensation of breathing using the diaphragm.

The sub-steps of practicing correct nasal breathing may include nasal breathing while lying down, nasal breathing while standing, and nasal breathing while sitting. It is preferable to perform all three of these actions. If nasal breathing while standing and nasal breathing while sitting are difficult, it is preferable to start with nasal breathing while lying down. Nasal breathing while lying down naturally encourages diaphragmatic breathing. Once you feel that you are breathing using your diaphragm by nasal breathing while lying down, you may proceed to nasal breathing while standing and nasal breathing while sitting. It is preferable to perform each of these three actions twice a day for two minutes each.

By lying down and breathing through your nose, you can remember the position of your diaphragm. It is a good idea to be aware that your solar plexus expands when you inhale and contracts when you exhale. For example, it is a good idea to imagine that there is a balloon inside your stomach.

By breathing through your nose while standing and while sitting, you can ensure that there is enough space for air to enter your abdomen, and you can feel the movement of your diaphragm with the correct posture. When breathing through your nose while standing and while sitting, it is best to do so with the correct posture, with your back slightly curved. In detail, you can achieve the correct posture by resting your weight on both feet, dropping your shoulders back comfortably, keeping your chin parallel to the floor, and lowering your arms to your sides. If you lean forward too far, the space for air to enter your abdomen will be narrowed, making it difficult to feel the movement of your diaphragm. For example, it is good to be aware that all the air you inhale goes to the bottom of your lungs.

The sub-step of proper nasal breathing should be performed with attention paid to breathing through the nose at the timing of the person doing the training, not allowing the chest and shoulders to move up and down, breathing lightly, and not making audible noises (points to note).

(Sub-step of breathing through the nose during walking)
The sub-step of breathing through the nose while walking allows the person undergoing the training to control his/her own breathing. It is particularly preferable for this sub-step to allow the person undergoing the training to learn light breathing. For example, the goal of this sub-step may be that the mouthpiece 10 worn in the oral cavity will not come off during the night when going to sleep after performing this sub-step, and that the person undergoing the training can walk for 60 seconds or more during this sub-step.

The sub-step of breathing through the nose while walking may include breathing through the nose for 30 seconds to regulate breathing, exhaling completely through the nose and then starting to walk while holding the nose from above, and stopping walking before it becomes difficult to breathe and breathing slowly through the nose. These three actions constitute one set, and it is preferable to repeat six sets. For example, six sets may be performed twice a day.

When performing the sub-step of nose breathing while walking, pay attention to whether you are breathing slowly, exhaling before breathing in, breathing through the nose with your mouth closed, and maintaining correct posture. Lifting your head makes it easier for the lower part of your head to rise to the roof of your mouth and makes it easier to maintain correct posture with a straight back. When pinching your nose, pinching it from above rather than below will prevent your mouth from being obscured. It will also make it easier to maintain correct posture.

The sub-step of breathing through the nose while walking is preferably performed while doing light exercise. Light exercise increases the concentration of carbon dioxide in the body and makes it easier to dissociate oxygen from the hemoglobin in the blood. By ensuring that sufficient oxygen is distributed to the cells in the body, it becomes easier to breathe through the nose properly.

The sub-step of breathing through the nose while walking should be performed with attention paid to breathing through the nose at the timing of the person doing the training, not getting out of breath from walking too much, not breathing heavily, not opening the mouth, etc. (Points to note)

(Sub-step to clear nasal congestion)
The sub-step of relieving nasal congestion allows the person to breathe through the nose with ease. This sub-step is preferably for learning the correct technique for nasal breathing. This sub-step is performed by the person undergoing training at appropriate times, such as when he or she has a stuffy nose, rhinitis, allergies, or a cold.

The sub-step of relieving nasal congestion may include breathing through the nose for 30 seconds to regulate breathing, pinching the nose from above after completely exhaling through the nose, slowly rocking the head from side to side while keeping the nose pinched, and stopping rocking the head before it becomes difficult to breathe and breathing through the nose. These four actions constitute one set, and it is preferable to repeat six sets. For example, six sets may be performed twice a day.

The sub-step of clearing nasal congestion is preferably performed while in a seated position.

The sub-step of relieving nasal congestion should be performed with your mouth closed, without shaking your head violently, while continuing to breathe through your nose, and without shortening the 30 seconds between sets (points to note).

[Tongue Step]
The Tongue step involves getting the tongue in the correct position. Once the correct tongue position is learned, the patient may proceed to another step. The Tongue step preferably continues for, for example, four months.

The tongue step may include placing the entire tongue on the roof of the mouth, clicking the tongue, and extending the tongue. These three sub-steps are preferably performed in this order. Including these three sub-steps makes it easier to learn the correct tongue position. Note that these three sub-steps are performed without the mouthpiece 10 being placed in the mouth.

(Substep 1: Place entire tongue on roof of mouth)
The sub-step of placing the entire tongue on the roof of the mouth preferably allows the subject to learn the correct tongue position, for example, the objective of which may be to maintain the tongue on the roof of the mouth for at least one minute.

The sub-step of placing the entire tongue on the roof of the mouth may include placing the tongue on a "spot" behind the front teeth, placing the entire tongue on the roof of the mouth, closing the mouth with the upper and lower teeth slightly apart (1-2 mm apart), and keeping the tongue on the spot. These four movements are preferably performed in this order. Each movement is preferably performed with the mouth closed.

By placing the tip of the tongue against the tongue tag portion 2 while the mouthpiece 10 is in the mouth, it becomes possible to place the tongue on the spot when the mouthpiece 10 is not in the mouth. When placing the tongue on the spot, care should be taken to ensure that the tip of the tongue does not directly touch the upper teeth. If the mentalis muscle moves when placing the entire tongue on the palate, it is a good idea to place the index finger on the chin. It is preferable to open the mouth one or two fingers wide. Care should be taken not to apply too much pressure to the tongue. If the upper and lower teeth come into complete contact when closing the mouth, this may lead to teeth grinding. It is preferable to keep the tongue on the spot for at least one minute.

When performing the sub-step of placing the entire tongue on the palate, it is preferable to pay attention to the following: making sure the tip of the tongue does not touch the upper teeth directly, that the tip of the tongue does not go too far back, that the tongue does not touch the lower teeth when the upper and lower teeth are brought closer together, that the mouth is not opened too wide, and that the tongue is not trembling or the facial muscles are not tense (points to note).

(Substep: Clicks tongue)
The tongue clicking sub-step can strengthen tongue strength. This sub-step preferably involves understanding that the entire tongue should be placed flat against the palate when at rest. For example, the goal of this sub-step may be to click the tongue 30 times in a row without moving the lower jaw, and to ensure that the tongue is placed in the correct position and the mouth is comfortably closed when at rest.

The sub-step of clicking the tongue may include opening the mouth and placing the tongue on a spot, raising the entire tongue to the roof of the mouth, and dropping the entire tongue down while keeping the mouth open to produce a loud sound. These three actions are preferably performed in this order.

When placing your tongue on the spot, make sure that you can place it comfortably on the spot. When raising your whole tongue up to the palate, it is preferable to be careful not to move your mentalis muscle, but to lift it using only the force of your tongue. When dropping your whole tongue down to make a loud sound (click), make sure that your tongue is flat against the palate before clicking. Make a loud, powerful click. Make sure that your lower jaw does not move when you click. It is preferable to perform each of these movements slowly and carefully. For example, by pausing the movement just before making a loud sound, you can become aware of the position of your whole tongue on the palate when at rest.

When performing the tongue clicking sub-step, it is advisable to pay attention to the following: not opening the mouth too wide, keeping the lower jaw open and motionless, moving the tongue independently, not moving too quickly, and not opening and closing the mouth (points to keep in mind).

(Sub-step: extend tongue)
More preferably, the tongue stretching sub-step is performed after confirming that the tongue can be maintained in the resting position (on the palate) for at least 60 seconds. This sub-step stretches the tongue muscles so that the tongue can be naturally placed entirely on the palate. For example, the goal of this sub-step may be to maintain the tongue in this position for one minute without trembling.

The sub-step of extending the tongue may include placing the tongue on the spot, raising the entire tongue to the roof of the mouth, opening the mouth as wide as possible, and maintaining this position for one minute. These four actions are preferably performed in this order.

The sub-step of extending the tongue is preferably performed using the force of the tongue, without applying force to the mentalis muscle. It is also preferable to perform the sub-step while making sure that the labial, buccal, and mental muscles are relaxed.

In the tongue extension substep, it is preferable to feel the tongue extend when opening the mouth.

The tongue extension substep should be performed while taking care to ensure that the tongue is not placed in a position different from its resting position, that the tongue is not vibrating, and that the tongue is not dropping or sliding sideways (points to note).

The tongue step may further include protruding the tip of the tongue, opening the tongue sideways, and moving the tongue up and down. These three sub-steps are preferably performed in this order. Including these three sub-steps makes it easier to learn the correct tongue position. These three sub-steps are preferably performed after learning the above three sub-steps. Note that these three sub-steps are also performed without the mouthpiece 10 being placed in the oral cavity.

(sub-step: stick out tongue)
The tongue thrust substep can stabilize and strengthen the intrinsic tongue muscles, for example, the goal of this substep can be to maintain a surfboard tongue position for 60 seconds.

The sub-step of protruding the tongue tip may include placing the tongue on the spot, lifting the tongue to the roof of the mouth, lowering the back of the tongue and gradually removing it from the roof of the mouth, and removing the tongue from the spot, opening the mouth wide, and protruding the tongue tip. These three actions are preferably performed in this order.

When placing your tongue on the spot, it is preferable to check that you can place your tongue comfortably on the spot. When sticking out the tip of your tongue, do not stick it out too far. Once your tongue has gained strength, you may stick it out outside your mouth. It is preferable to start by maintaining the tongue tip sticking out for 10 seconds, gradually increasing the time. At the end of all three movements, return the tongue to the spot. If your tongue muscles become tired and your tongue starts to tremble, return the tongue to the spot as well. Keep your mouth as wide as possible and control your tongue by forming it like a surfboard. Your tongue may be slightly curved.

The sub-step of sticking out the tip of the tongue should be performed while taking care that the tongue does not touch the molars or the corners of the mouth, that the back of the tongue is away from the lower teeth, and that the tongue is not moving excessively (Points to note).

(Sub-step: Open your tongue to the side)
The sub-step of opening the tongue to the side is preferably performed after the sub-step of protruding the tongue tip is reliably performed. The sub-step of opening the tongue to the side can train the intrinsic and extrinsic tongue muscles. The intrinsic tongue muscles help to shape the tongue. The extrinsic tongue muscles help to smooth the tongue movement. For example, the goal of this sub-step may be to perform this sub-step 15 or more times in succession without the tongue trembling or the lips and cheeks moving.

The sub-step of opening the tongue to the side may include placing the tongue on a spot, gradually moving the back of the tongue away from the palate, opening the mouth wide and pushing out the tip of the tongue, and opening and thickening the tongue to the side. These four actions are preferably performed in this order.

When placing the tongue on the spot, it is preferable to check that the tongue can be placed comfortably on the spot. When opening the tongue to the side and thickening the tongue, it is preferable to keep the tongue outside the mouth. It is preferable to maintain the tongue tip thrust out as far as possible and the tongue thickening for 2 seconds each. It is preferable to slowly repeat this set 5 to 15 times. After completing all four movements, return the tongue to the spot.

The sub-step of opening the tongue to the side can be considered an extension of the sub-step of sticking out the tip of the tongue. By performing the sub-step of opening the tongue to the side after the sub-step of sticking out the tip of the tongue, you can train your tongue muscles more effectively and gain control over them.

When doing the sub-step of opening the tongue to the side, it is advisable to pay attention to the following points: making sure the back of the tongue is away from the lower teeth; not rushing the movement; controlling the movement; not letting the tongue tremble or move around the lips or cheeks; and not letting the lips and tongue touch when moving the tongue (points to keep in mind).

(Sub-step: Move your tongue up and down)
The sub-step of moving the tongue up and down is preferably performed after the sub-step of opening the tongue to the side can be performed reliably and the correct position of the tongue can be acquired. It is preferable that the sub-step of moving the tongue up and down allows the tongue to be controlled. It is preferable that the sub-step checks how the tongue moves when swallowing. For example, the goal of the sub-step may be to perform the sub-step 15 or more times in succession without moving the lower jaw.

The sub-step of performing the tongue up and down movement may include placing the tongue on a spot, sucking the tongue up to the palate and holding it there for 2 seconds, and gradually moving the back of the tongue away from the palate and holding it there for 2 seconds. These three movements are preferably performed in this order.

When placing the tongue on the spot, it is preferable to check whether the tongue can be placed on the spot comfortably. It is preferable to perform the following 10 to 15 times: sucking the tongue up against the palate and holding it there for 2 seconds, and then gradually removing the back of the tongue from the palate and holding it there for 2 seconds. The sub-step of moving the tongue up and down also corresponds to the preparatory stage for the swallowing step, so it is preferable to perform each step carefully.

When performing the sub-step of moving the tongue up and down, it is advisable to pay attention to not opening the mouth too much, not moving the lower jaw, and not letting the tongue move off the spot (points to keep in mind).

[Swallowing step]
The swallowing step involves learning to swallow correctly. The swallowing step is performed in front of a mirror. Once the correct swallowing has been learned, the patient may proceed to another step. The swallowing step is preferably continued for, for example, three months.

The swallowing step may include drinking in the correct manner, pulling the mouth to drink, and wearing the mouthpiece 10 in the oral cavity and drinking water. These three sub-steps are preferably performed in this order. Including these three sub-steps makes it easier to learn how to swallow correctly. Note that of these three sub-steps, all sub-steps except for the sub-step of wearing the mouthpiece 10 in the oral cavity and drinking water are performed without wearing the mouthpiece 10 in the oral cavity.

(Sub-steps for correct drinking)
The sub-step of learning the correct way to swallow allows the person to learn how to swallow correctly. This sub-step is preferably performed while checking the direction of swallowing in a mirror. In this sub-step, it is preferable for the person doing the training to feel the swallowing himself. For example, the goal of this sub-step may be to swallow correctly 5 to 10 times or for 2 minutes.

The sub-steps of swallowing correctly may include placing the tongue on the spot, closing the mouth with the upper and lower teeth slightly apart, swallowing the saliva with a waving tongue movement while bringing the upper and lower teeth into contact, and returning the tongue to the spot after swallowing. These four actions are preferably performed in this order. At the end of the four actions, the tongue is temporarily returned to the spot.

When placing your tongue on the spot, it is a good idea to check that you can place your tongue on the spot comfortably.

The sub-steps of swallowing correctly should be performed with attention paid to not nodding, not leaving the tongue on the spot, not blinking, and not licking the lips after swallowing (points to note).

(Sub-step: pull lip to drink)
The sub-step of pulling the mouth to drink is preferably performed after confirming that the sub-step of correct drinking has been acquired. The sub-step of pulling the mouth to drink allows the subject to feel swallowing by himself. In this sub-step, the subject can check how the cheek and lip muscles move by pulling the mouth. For example, the goal of this sub-step may be to clear all the points to note, which will be described later.

The sub-step of pulling the mouth to swallow may include placing the tongue on the spot, slightly opening the upper and lower teeth, pulling the mouth, and swallowing the saliva by touching the upper and lower teeth and making a flicking motion of the tongue. These four actions are preferably performed in this order. At the end of the four actions, the tongue is temporarily returned to the spot.

When placing the tongue on the spot, it is preferable to check that the tongue can be placed on the spot comfortably. The sub-step of pulling the mouth to swallow is preferably done while checking what is happening in the mouth during swallowing.

When doing the sub-step of pulling your mouth to drink, it is advisable to pay attention to pulling your cheeks in just enough to not cause pain, not blinking or nodding, not letting saliva bubbles come out from between your teeth, and not sticking out your tongue (points to keep in mind).

(Sub-step of placing the mouthpiece in the mouth and drinking water)
The sub-step of wearing the mouthpiece 10 in the oral cavity and drinking water is preferably performed after confirming that the sub-step of pulling the mouth to drink has been mastered. The sub-step of wearing the mouthpiece 10 in the oral cavity and drinking water allows the patient to learn how to swallow liquid. In this sub-step, it is preferable to wear the mouthpiece 10 in the oral cavity and learn how to swallow correctly while feeling the movement of the tongue. For example, the goal of this sub-step may be to eliminate excessive movement of the lips, chin, and cheeks. This sub-step is performed using a paper cup filled with water.

The sub-step of placing the mouthpiece 10 in the oral cavity and drinking water may include placing the mouthpiece 10 in the oral cavity, placing the tip of the tongue against the tongue tag portion 2, pouring water through the air hole 4 of the mouthpiece 10, collecting the water and bringing it to the center of the tongue, and raising the tongue to the roof of the mouth and pulling it back so as not to remove the tip of the tongue from the tongue tag portion 2. After swallowing, the tip of the tongue is kept in contact with the tag portion 2. It is preferable to perform these four actions in this order.

When placing the tip of the tongue against the tongue tag 2, it is preferable to check that the tip of the tongue can be placed comfortably against the tongue tag 2. When gathering water and bringing it to the center of the tongue, it is a good idea to be conscious of cupping the tongue. Only a small amount of water should be in the mouth. By pulling the tongue back, the water is swallowed by the undulating movement of the tongue. Drinking water with the mouthpiece 10 still attached to the mouth can teach the child how to swallow liquids. Wearing the mouthpiece 10 encourages correct swallowing.

It is preferable to perform the sub-step of placing the mouthpiece 10 in the mouth and drinking water while paying attention to the following: making sure that the tip of the tongue does not leave the tongue tag portion 2 at the start and end, not pressing the tongue against the tongue tag portion 2 (which may cause water to come out of the side of the mouth), drinking only a small amount of water rather than a large amount, not pressing the tongue against the mouthpiece 10 (which may cause water to come out of the mouth), and not blinking or nodding (points to note).

The swallowing step may further include drinking water without placing the mouthpiece 10 in the oral cavity and holding the water on the tongue. These two sub-steps are preferably performed in this order. Including these two sub-steps makes it easier to learn to swallow correctly. These two sub-steps are preferably performed after the above three sub-steps have been mastered. Note that these two sub-steps are performed without placing the mouthpiece 10 in the oral cavity.

(Substep 2: Drink water without placing the mouthpiece in the mouth)
The sub-step of drinking water without wearing the mouthpiece 10 in the oral cavity is preferably performed after confirming that the sub-step of drinking water with the mouthpiece 10 in the oral cavity has been mastered. The sub-step of drinking water without wearing the mouthpiece 10 in the oral cavity allows the patient to learn the correct swallowing method. For example, the goal of this sub-step may be to clear all the points to note, which will be described later. This sub-step is performed using a paper cup filled with water.

The substep of drinking water without the mouthpiece 10 in the mouth may include placing the tongue on the spot, lifting the tongue to the roof of the mouth and away from the back of the tongue, and swallowing the water with a wavy tongue motion, lifting the tongue to the roof of the mouth and slightly touching the upper and lower teeth so that the water gathers in the middle of the tongue and does not move the tongue away from the spot. After swallowing, the tongue is left on the spot.

When placing the tongue on the spot, it is preferable to check whether the tongue can be placed on the spot comfortably. The sub-step of drinking water without the mouthpiece 10 in the mouth is preferably performed in the correct posture so that the jaw is parallel to the ground. When swallowing water, the upper and lower teeth come into slight contact.

It is preferable to perform the sub-step of drinking water without placing the mouthpiece 10 in the mouth, paying attention to the following: making sure that the tongue does not leave the spot at the start or end, that the mentalis muscle, cheeks, or lips are not moved, that the tongue is not protruding, that small amounts of water are drunk rather than large amounts, and that blinking or nodding is not performed (points to note).

(Sub-step: Hold water on tongue)
The sub-step of collecting water on the tongue is preferably performed after confirming that the sub-step of drinking water without wearing the mouthpiece 10 in the oral cavity has been acquired. The sub-step of collecting water on the tongue can be said to be a sub-step that summarizes the tongue step and the swallowing step. This sub-step preferably allows the user to firmly complete the previous sub-steps, such as the sub-step of placing the entire tongue on the palate, the sub-step of moving the tongue up and down, and the sub-step of drinking in the correct way. This sub-step allows the water collected on the tongue to be sealed between the tongue and the palate. For example, the goal of this sub-step may be to clear all the contents of the points to note, which will be described later. This sub-step is performed using a paper cup filled with water.

The sub-step of collecting water on the tongue may include the sub-steps of placing the tongue on the spot, closing the mouth with the upper and lower teeth slightly apart, taking a small amount of water, collecting the water in the middle of the tongue and sealing it up against the roof of the mouth, and tilting the head to the right, then left, then forward, then backward, to perform the correct drinking technique. These four actions are preferably performed in that order. The tongue is left on the spot after swallowing.

When placing the tongue on the spot, it is preferable to check whether the tongue can be placed comfortably on the spot. When performing the sub-step of correct drinking, for example, if a little water spills when tilting the head to the left, it is determined that the tongue strength on the left side is weak. When performing the sub-step of collecting water on the tongue, it is preferable to perform this in the correct posture with the chin parallel to the ground, and to close the lips after taking in a little water. When swallowing water, the upper and lower teeth should come into slight contact.

The sub-step of collecting water on the tongue may be performed in combination with the sub-step of drinking by pulling the mouth. That is, the sub-step of drinking correctly may be performed by pulling the mouth. If water comes out from between the teeth, it is determined that the patient has not mastered swallowing correctly.

It is recommended that the sub-step of collecting water on the tongue be performed with due attention to the following: the tongue should not leave the spot at the beginning or end of the step, the mentalis muscle, cheeks, or lips should not be moving, the tongue should not be protruding, small amounts of water should be consumed rather than large amounts, there should be no blinking or nodding, and no water should be absorbed from under the tongue (points to note).

[Lip and Cheek Step]
The lip and cheek step involves improving lip sequestering defects. The lip and cheek step preferably lasts for, for example, two months.

The lip and cheek step may include using the orbicularis oris muscle by wearing the accessory member 20 of the mouthpiece 10, smacking the lips, and puffing the mouth. These three substeps are preferably performed in this order. Including these three substeps makes it easier to improve insufficient lip closure. Note that of these three substeps, except for the substep of wearing the accessory member 20 of the mouthpiece 10 and using the orbicularis oris muscle, the mouthpiece 10 or accessory member 20 are not worn in the oral cavity.

(Sub-step: Attaching the mouthpiece accessory and using the orbicularis oris muscle)
The sub-step of using the orbicularis oris muscle by wearing the accessory member 20 of the mouthpiece 10 can improve insufficient lip closure, such as tension in the mentalis muscle. In this sub-step, it is preferable to learn to use the orbicularis oris muscle, rather than the mentalis muscle.

2 is a schematic perspective view of the accessory member 20. The accessory member 20 includes a main body portion 7, a strap portion 8, and a lip plate portion 9. The main body portion 7 has a rod shape and is a portion that connects the strap portion 8 and the lip plate portion 9. The strap portion 8 is located at one end of the main body portion 7. The shape of the strap portion 8 is not particularly limited. For example, in the example shown in FIG. 2, the strap portion 8 includes an insertion portion 81 with a spherical tip and a ring-shaped engagement portion 82 that can engage with the insertion portion 81. The lip plate portion 9 is located at the other end side of the main body portion 7. The lip plate portion 9 has a planar shape. When the accessory member 20 is used, the lip plate portion 9 is placed between the upper lip and the lower lip. The lip plate portion 9 includes a first lip plate portion 91 located at the other end of the main body portion 7 and a second lip plate portion 92 located closer to the strap portion 8 than the first lip plate portion 91.

The accessory member 20 is made of an elastic resin material. An example of the elastic resin material is medical grade silicone.

The sub-step of wearing the accessory member 20 of the mouthpiece 10 and using the orbicularis oris muscle may include: pinching the first lip plate portion 91 of the accessory member 20 between the upper and lower lips and placing the tip of the tongue on the spot; and pulling the accessory member 20 vertically, diagonally upward, and diagonally downward for 30 seconds each. It is preferable to perform these two actions in this order.

In the sub-step of attaching the accessory member 20 of the mouthpiece 10 and using the orbicularis oris muscle, it is preferable not to change the direction of pulling in a short period of time.

When attaching the accessory member 20 of the mouthpiece 10 and using the orbicularis oris muscle, it is preferable to perform the sub-step while taking care not to place the entire tongue against the palate, not to suck the first lip plate portion 91 against the teeth, and not to move any muscles other than the orbicularis oris (points to note).

(substep: smacking lips)
The sub-step of smacking the lips allows the upper and lower lips to be rolled evenly. This sub-step preferably strengthens the orbicularis oris muscle. For example, the goal of this sub-step may be to clear all of the points to note, which will be described later.

The sub-step of smacking the lips may include rolling the upper and lower lips inward equally and opening the lips forcefully to make a loud "pop" sound. These two movements are preferably performed in this order. These two movements are preferably repeated at least 20 times.

By repeating the lip-smacking substep, you can strengthen your orbicularis oris muscle and produce a louder sound. To produce a louder sound, open your mouth wider. If your orbicularis oris muscle is weak, it will be difficult to produce a loud sound.

When performing the sub-step of smacking your lips, it is advisable to be careful not to make a small "slurp" sound (Note). Note that in this sub-step, you do not need to be conscious of placing your tongue on the spot.

(Sub-step: inflate the mouth)
The sub-step of expanding the mouth can reduce the force of the muscles that push the teeth. This sub-step preferably stretches the orbicularis oris muscle, including the mentalis muscle. For example, the goal of this sub-step may be to clear all of the points to note, which will be described later.

The sub-step of expanding the mouth may include placing the tongue on a spot, gently separating the upper and lower teeth and closing the lips, pursing the lips and making them pointy, and blowing air around the lips and cheeks. These four movements are preferably performed in this order. These four movements are preferably repeated until the muscles around the lips and cheeks become fatigued. If tension develops in the mentalis muscle, it may be helpful to massage it.

When doing the sub-step of inflating the mouth, it is recommended to inflate the air from the inside and not to roll the lips inward (points to note).
