Description

The present invention relates to a periodontal tissue massage device using vibration stimulation.

Periodontal disease is an infectious disease caused by anaerobic bacteria that causes alveolar bone resorption in the oral mucosa. Therefore, periodontal disease is caused by removing bacteria from the tooth neck, which is the boundary between the living body and the outside world and is the site of bacterial invasion. Plaque removal was the most basic treatment method for periodontal disease, but when it comes to treating periodontal disease using a toothbrush, massaging the gums is more clinically effective than removing plaque. It has been reported that it is high (see Non-Patent Documents 1 and 2).
However, although cell images of the periodontal tissue after brushing have shown the mechanism by which periodontal disease is improved by massaging the gums, the functional mechanism leading to this improvement has not been elucidated. .

Generally, the effect of massage is simply thought to be to promote peripheral blood circulation, but for the massage effect to occur, the functions of the three types of vascular systems that make up the microcirculation system are required. It is thought that they are both involved, and that the effect of promoting blood circulation is not necessarily the only one.
For example, in the case of ultrasonic massage, when the ultrasonic waves are absorbed under the epidermis, the vibration energy is converted into thermal energy and has the effect of warming the subepidermal tissue. It is a warming effect on the sub-epidermal tissue by heat ray radiation with penetrating action, and high-frequency massage also uses the property of high-frequency waves to reach deep tissue to generate Joule heat deep in tissues such as muscles. It has the effect of warming deep tissue.
Therefore, the essence of the effect of the above-mentioned massage is a thermal effect, and the increase in tissue temperature promotes tissue metabolism due to the Q10 effect, but the thermal effect widens the diameter of the artery, thereby increasing the perfusion pressure. Increased blood flow to tissues promotes venous blood flow, which further promotes metabolism. Increased blood flow increases tissue fluid and increases temperature, which also promotes peristaltic movement of lymph vessels. Therefore, the main target area for massage operations that produce a thermal effect is the arterial system.

On the other hand, low-frequency muscle massage utilizes the electrical stimulation effect of low-frequency current on the muscles to cause the muscles to relax and contract, and by creating intermittent compression of the surrounding area, the veins with venous valves are stimulated. It acts to produce a powerful pumping and milking action. This increases venous blood flow and passively increases arterial blood flow by increasing the perfusion of blood through the muscles.
Furthermore, increased muscle temperature and muscle movement due to increased muscle metabolism and increased arterial blood flow both have the effect of inducing or promoting peristaltic movement of lymph vessels, and these factors collectively contribute to the microcirculatory function of tissues. The main target area for massage operations that promote blood flow is the venous system, as it is believed that massage therapy improves metabolism, relieves fatigue, and provides a refreshing feeling.

In the pneumatic lymphatic massager (see Non-Patent Document 3), by applying intermittent pressure stimulation to tissues using an air bag to an extent that does not obstruct blood circulation, a pumping effect is generated on veins and lymph vessels that have valves, and The increase in tissue pressure promotes the uptake of tissue fluid into veins and lymphatic vessels, which promotes the drainage of tissue fluid.The main target area for massage operations that promote the drainage of tissue fluid is the veins. system and lymphatic system.

The microcirculatory system has complex interactions, and the effect of massage operations affects all of the arterial, venous, and lymphatic systems in the massaged area, so it is important to simplify the target area for massage operations. Although they cannot be divided into three types, massage can be thought of as three types: massage methods in which the arterial system primarily functions, massage methods in which the venous system primarily functions, and massage methods in which the lymphatic system primarily functions.

On the other hand, the toothbrushing method described above, which places more emphasis on massaging the gums than removing plaque, seems to be characterized by intermittent pressure stimulation applied to the gums in the interdental papilla compared to other toothbrushing methods. Since toothbrushing is equipped with a reflux support mechanism that sends venous blood and lymph fluid to the central nervous system with slight pressure fluctuations, it is likely that the same mechanism works in this method of brushing teeth, promoting venous blood flow and lymph transport. It is possible to consider this to be a cause with high clinical efficacy.
Body fluids, which are extracellular fluids, can be divided into blood, tissue fluid, and lymph.The pumping action of the heart has a high ability to eject blood, but it does not have a high ability to circulate venous blood, and it does not have the ability to circulate lymph. . Therefore, living organisms have a mechanism that allows venous blood and lymph to flow back to the heart without relying on the heart's strength.
This is due to the rectifying action of valves in veins and lymphatic vessels that prevent backflow and allow venous blood and lymph to flow only toward the central region, and the natural principle that blood and lymph flow from areas of high pressure to areas of low pressure. This mechanism utilizes surrounding pressure fluctuations to promote the return of venous blood and lymph to the heart.
The pulsation of the arteries in the companion veins that run close to each other promotes the return of venous blood in the adjacent veins, and even changes in intrabody pressure in the thoracic and abdominal cavities associated with respiratory movements function within this mechanism. However, this function is particularly strong in the vascular system sandwiched between the leg muscles, and it is generally known that leg muscle movement acts like a pump and promotes the return of venous blood and lymph fluid. It is well known as a muscle pump effect (see Non-Patent Document 4).
If we apply this to massaging the gums using a toothbrush, we can see that the pressure applied to the gums compresses the veins and makes them flattened, increasing the internal pressure of the veins. blocked by venous valves. However, on the central side, venous valves located on the central side open toward the central side, and venous blood in the pressurized veins is sent to the central side where the pressure is lower.
Afterwards, when the pressure applied to the vessel is removed, the vessel, which has become flat due to the pumping of venous blood, moves back to its original shape due to the elasticity of the vessel. Pressure is generated, and venous blood from the periphery is drawn into the empty vessel, causing a movement to fill the vessel with venous blood again.
At that time, the venous valves on the central side are closed, preventing the pumped venous blood from flowing back toward the periphery, but the venous valves on the peripheral side are open, allowing venous blood to flow in from the periphery and pulsating. Venous blood accumulates in the tube, and the next pressure stimulus fills it up again and sends it out to the central region.
The promotion of peripheral circulation through pumping action is to efficiently repeat this process, but in order to make this possible, the inside of the vessel must be filled with venous blood again before pressurization is applied again. It is necessary to wait until venous blood from the periphery flows into the later vessels to refill them. Therefore, it is necessary to allow sufficient time (refill time) before pressurizing again, and this is an important condition for producing an efficient pumping action through intermittent pressure stimulation.
However, if the massage method is such that the next intermittent pressure stimulation occurs quickly and repeatedly before the inside of the blood vessel is not sufficiently filled with venous blood, the venous blood to be pumped out may not be enough to fill the blood vessel. The next pressure stimulus will be repeated without being accumulated.
As a result, the amount of venous blood delivered per session gradually decreases, until eventually no effective delivery of venous blood occurs, which is essentially equivalent to occluding the vein.
Such a phenomenon is similar to the mechanism of ventricular fibrillation and atrial fibrillation, in which effective cardiac output is drastically reduced despite a high heart rate, leading to serious conditions. No quantitative data were available regarding the appropriate frequency of intermittent pressure stimulation.
Therefore, by applying the maximum heart rate of approximately 200 beats/min, which is considered to be the largest frequency of periodic pressure fluctuations that occur physiologically in the human body, intermittent pressure with a frequency of approximately 200 beats/min or less If it is a stimulus, it can be assumed that the frequency is already physiologically functional in the living body and is sufficient to ensure the refill time required by peripheral veins with valves.
Then, in the toothbrushing method in which the toothbrush is operated using the hand, which is said to have a large massaging effect, it is considered that the frequency of brushing does not deviate from the above range.
However, in order for the pumping action to occur, the presence of venous valves in the pressurized area is required, and in the periodontal tissue, a large number of venous valves are only observed at the buccal transition area in both the upper and lower jaws (Non-patent Document 5), it is thought that intermittent pressure stimulation localized to the gums of the interdental papilla does not produce a pumping effect that promotes blood flow, and that intermittent pressure stimulation localized to the gums of the interdental papilla has a high clinical effect. This can be considered to be due to factors other than blood flow promotion, which is mainly involved in arteries and veins.

The interdental papilla of the periodontal tissue has a rich capillary network just below the epithelium, and is also characterized by being rich in lymph vessels.
In lymph vessels, slight pressure fluctuations, slight tension, slight vibrations, etc. induce peristalsis when peristalsis has stopped, and promote peristalsis when peristalsis is occurring. Therefore, intermittent pressure stimulation of the gums by brushing is considered to promote peristaltic movement of lymph vessels.
Furthermore, granular components such as blood cells, bacteria, or their remains that have leaked into tissue spaces due to inflammation, and substances with large molecular weights such as proteins cannot permeate through capillaries (see Non-Patent Document 6). They can only be eliminated from the periodontal tissue through the lymphatic vessels that pass through them, and the improvement of inflammatory symptoms caused by brushing cannot be considered without the involvement of the lymphatic system.
Blood, lymph, and tissue fluids are extracellular fluids in the body, and water, gases, electrolytes, other solutes, and small amounts of proteins with small molecular weights in the blood pass through the capillary walls and reach the interstitial spaces. After being affected by cellular metabolism, most of the fluid returns to the blood vessels, but tissue fluid containing small amounts of proteins and other substances with large molecular weights moves to the lymph vessels, forming lymphatic flow, and the lymph flows into the venous angle. This allows all pumped blood to return to the heart.
The main driving force for lymph flow is said to be active contraction of the lymph vessel wall, but passive pressure fluctuations due to external forces such as muscle contraction, arterial pulsation, tissue massage, and respiratory movement It also greatly affects the promotion of lymph flow and the reflux of lymph fluid (see Non-Patent Document 6).
Therefore, intermittent pressure stimulation by a toothbrush can tension the anchoring filaments of the lymphatic vessels, draw tissue fluid into the lymphatic vessels, induce or promote peristalsis of the lymphatic vessels, promote lymph flow, and increase lymphatic transport. Bacteria and white blood cells that can only be transported by lymph vessels, their dead bodies, toxins, various enzymes that cause tissue lysis, migratory factors that cause cell infiltration, vascular permeability factors, blood coagulation factors, etc. The negative chain reaction of inflammation is stopped by draining the complex immune-related substances and inflammatory substances caused by inflammation from the periodontal tissue through the lymphatic vessels and purifying the periodontal tissue. According to Starling's hypothesis (see Non-Patent Document 6), the inflow of tissue fluid into the venous capillaries is suppressed and the increase in vascular permeability is suppressed, and substances with large molecular weight are excreted and the colloid osmotic pressure of tissue fluid is lowered. As the volume increases, the venous blood flow increases, which lowers the hematocrit value and lowers the viscosity of plasma, making it easier for venous blood to flow, which is thought to passively increase the arterial blood flow.
This increases the amount of oxygen supplied to the periodontal tissue, improves the anaerobic environment within the periodontal tissue, suppresses anaerobic bacteria, and normalizes and accelerates the metabolism of the periodontal tissue, resulting in collagen production. In addition to increasing the synthetic ability and proliferative ability of fibroblasts, it also normalizes the turnover of adherent epithelial cells, which is thought to restore the repair and defense abilities of the periodontal tissue and advance the healing mechanism of periodontal disease. .
From the above, the reason why inflammatory symptoms of the oral mucosa can be improved by brushing the gums using this method and a high clinical effect can be obtained is that intermittent pressure stimulation induces the inflow of tissue fluid into the lymphatic vessels and the peristalsis of the lymphatic vessels. , can be considered to be the result of an effect of increasing lymphatic transport by promoting lymph flow.
Therefore, if the patient is suffering from periodontal disease, massage that primarily stimulates the lymphatic system is considered suitable.

On the other hand, in healthy periodontal tissue that is clearly not affected by periodontal disease, there is no abnormality in the amount or composition of tissue fluid, and there is no abnormality in the function of the microcirculation system, so the drainage of tissue fluid is difficult. Delivering sufficient nutrients and oxygen to each cell in the periodontal tissue to promote metabolism activates each cell, maintains the health of the tissue, and maintains an aerobic environment within the periodontal tissue. Massage, which stimulates the functioning of the arterial system, is thought to be effective in preventing periodontal disease, as it leads to the suppression of anaerobic bacteria.

However, an increase in tissue blood flow due to an increase in arterial blood flow is due to increased vascular permeability due to inflammation, etc., since the amount of plasma filtration from arterial capillaries physiologically increases in proportion to blood flow. If this occurs, there is a risk that tissue fluid will increase excessively and cause edema. Furthermore, edema expands the distance that oxygen diffuses from the capillaries, leading to insufficient oxygen supply to the periodontal tissues and causing anaerobic conditions. environment and becomes a factor that worsens inflammation.
On the other hand, the epithelium attached to the inner gingival margin of the tooth neck, which is the transition area between the inside and outside of the body, is constantly exposed to bacterial invasion, so people often suffer from periodontal disease without being aware of it. , it is necessary to take into consideration that vascular permeability may be increased at any time.
Therefore, when brushing the gums, it is desirable to perform a massage operation that not only promotes arterial blood flow, but also venous blood flow and lymph flow, or that has these effects. Performing a massage afterwards is also effective in suppressing edema caused by massage and preventing inflammation from worsening, and is also effective in improving the microcirculatory system and preventing periodontal disease. Conceivable.

Traditionally, it has been known that vibration stimulation with large amplitude, such as a chainsaw, reduces the sensitivity of blood vessels to NA (noradrenaline), expands the diameter of the artery, and increases blood flow. However, after vibration stimulation, the sensitivity to NA decreases. It was revealed in the investigation of the mechanism of the onset of white wax disease that this increase causes white wax disease (see Non-Patent Document 6).
However, at the same time, it was also revealed that the increased sensitivity to NA after such large-amplitude vibration stimulation does not occur when the frequency of the vibration stimulation is below 10 Hz or when the vibration stimulation time is less than 30 minutes. (See Non-Patent Document 6).

In addition, experiments using oscillatory negative internal pressure stimulation of lymph vessels have shown that small-amplitude oscillatory internal pressure changes induce automaticity in stationary lymph vessels, and that lymph vessels that already exhibit automaticity are able to maintain their existing peristaltic rhythm. It has also been revealed that it promotes (see Non-Patent Document 6).

On the other hand, in recent years, it has been revealed that NO (nitric oxide) is a substance discovered by Furchgott et al. in 1980 that has the effect of relaxing the smooth muscle of the blood vessel wall and expanding the vessel diameter. (See Patent Document 7) Since the blood flow rate increases, shear stress stimulation on arteriolar endothelial cells increases, and a large amount of NO is secreted from the endothelial cells, vascular smooth muscle relaxes, and the vascular diameter widens. In addition, it was known that endothelial cells of lymph vessels also produce and secrete NO in proportion to the magnitude of shear stress stimulation caused by lymph flow. (See Non-Patent Document 8).
Furthermore, because lymph vessels have extremely high passive extensibility, when NO is secreted from the endothelial cells of lymph vessels, the smooth muscles of the lymph vessels relax and lymph fluid temporarily accumulates within the lymph vessels. As a certain amount of lymph accumulates, the smooth muscles in the walls of the lymph vessels are stretched, causing a reflex contraction in response to the tension, and a large amount of accumulated lymph is rapidly pumped toward the central nervous system. It was also known that lymph transport is promoted (see Non-Patent Document 8).
From the above, it is clear that shear stress stimulation caused by blood flow acts on the endothelial cells of blood vessels and lymphatic vessels, and as blood flow and lymph flow increase, shear stress stimulation increases, and smooth muscle relaxing substances Since NO is produced and secreted, vibrational stimulation that affects the velocity of blood flow and lymph flow relaxes the smooth muscles of arterioles and lymph vessels, promoting arterial blood flow and lymph transport. It is thought that it is possible to cause

Vibration stimulation is said to be able to provide a feeling of recovery from muscle fatigue and a feeling of refreshment, and has already been widely used for body massage, but the mechanism was generally thought to be due to the effect of promoting blood circulation.
Various massage devices that use vibration stimulation are available for periodontal tissues, and they are thought to have effects on both the arterial system and the lymphatic system. In terms of massage operation, there is no distinction made between the effect on the arterial system and the effect on the lymphatic system, and the magnitude of the effect of vibration stimulation on the arterial system and the effect on the lymphatic system are different. There is no technical idea to adjust the relative proportions of the vibrations, and the vibration intensity ranges from a vibration intensity that comfortably affects the arterial system to the smallest possible vibration intensity that suppresses the action of the arterial system and emphasizes the action of the lymphatic system. A vibrating periodontal tissue massager with a stepless adjustment function of the vibration motor output, which aims to enable stepless use of the periodontal tissue, has not been developed.
In a periodontal tissue massage device for the purpose of preventing and treating periodontal disease, the present invention aims to improve the relative magnitude of the effect of the arterial system and the lymphatic system during vibration stimulation. In addition to being able to adjust the ratio of vibrations, unnecessary vibrations and noise are reduced, and vibration stimulation is generated with a simple mechanism and small power.The device can be applied to the narrow oral environment filled with saliva and can be used with the mouth closed. The object of the present invention is to develop a vibrating periodontal tissue massager that enables periodontal tissue massage and has the function of simultaneously massaging multiple interdental papillae.

Arterioles control the blood flow to tissues, and the arterioles are the targets of vibration stimulation during massage, and their blood pressure is 40 to 45 mmHg. Similarly, the lymphatic pressure in the lymphatic vessels that are the target of vibration stimulation is lower than the tissue pressure, which is less than 2 to 5 mmHg, so there is a pressure of about 400 g/cm ² or more between the arteriole pressure and the lymph pressure. There is a difference (see Non-Patent Document 6).
In addition, arterioles have thick wall walls relative to their diameter and a well-developed smooth muscle layer, whereas lymph capillaries are composed of a single layer of flat endothelial cells, which gradually form a wall of lymph capillaries. Even though the lymph vessels increase in thickness and become thin lymph vessels with valves, the vessel walls are still thin with only collagen fibers, elastic fibers, and a small amount of smooth muscle fibers existing outside the endothelial layer.
Furthermore, lymph vessels have the property of inducing or promoting peristalsis by sensitively responding to small pressure fluctuations, vibration stimulation, stretching stimulation of lymph vessel walls, and the like.
Furthermore, in the oral mucosa, small arteries are located deeper than many lymph vessels.
Based on these facts, vibrational stimulation applied to the surface layer of the oral mucosa has a different effect on the flow in the arterioles and lymphatic vessels, and is not applied to the arterioles and lymphatic vessels in the massaged area. It is thought that the sensitivity to vibration stimulation is different.
Therefore, by providing a massage device with a function to steplessly adjust the intensity of vibration stimulation from a massage, from a vibration intensity that feels comfortable to a vibration intensity that can be slightly detected, the effect of NO on the arterial system can be improved. It is possible to steplessly change the vibration intensity from a large vibration intensity to a vibration intensity that hardly occurs, and it is possible to change the relative proportion to the magnitude of the NO action in the lymphatic system, and the arterial system. It is possible to adjust steplessly the range from the vibration intensity that emphasizes the effect on the arterial system to the vibration intensity that suppresses the effect on the arterial system and emphasizes the effect on the lymphatic system. .
Therefore, in the present invention, the vibration motor control circuit is provided with a variable resistor, and the variable resistor is capable of stepless adjustment in the range from the rated output state of the vibration motor to the stop of the vibration motor. This method uses a vibration motor as a source device for generating vibrations, and directly inserts the vibration motor into the oral cavity to transmit the vibrations to the oral mucosa without using a motion conversion mechanism or motion transmission mechanism other than the vibration motor. The main means is that the vibration motor is waterproof, has a vertically cylindrical shape, and serves as a transition part between the intraoral installation part and the extraoral installation part that connects the vibration motor and vibration motor control circuit. Another means is that the shape of the object is thin.

The effects of the present invention are shown below.

It is well known that the large vibrations to which people working with chainsaws were exposed affected arteries, sympathetic nerves, lymphatic vessels, etc., causing a vibration injury called white wax disease.
Furthermore, it has been known that a phenomenon similar to white wax disease occurs in the arteries due to vibrations, which is also observed when using vibrators for motorcycle handlebars and shoulder tapping [see Non-Patent Document 8].
The vibrations generated by the vibration motor used in the present invention have a smaller amplitude than the vibrations of commonly available electric toothbrushes, and a lower frequency than electric toothbrushes called ultrasonic toothbrushes or sonic vibration toothbrushes, which have an effect on blood vessels. The strength of the vibration stimulation is smaller than that of other electric toothbrushes and gum massage devices currently in use. Since it is possible to make stepless adjustments from the motor's rated output state to vibration stopping, it is possible to make stepless adjustments from the normal sensible vibration intensity to the weak vibration intensity that can be detected. By utilizing the difference in the magnitude of the effect of the applied vibration stimulation on small arteries and the magnitude of the effect on lymphatic vessels, we can differentiate the effect mainly on the arterial system and the effect mainly on the lymphatic system. It can be used for different purposes.
This makes it possible to selectively use vibration stimulation massage, which is highly effective in protecting healthy gums and preventing periodontal disease, and vibration stimulation massage, which is highly effective in promoting healing of periodontal disease. Since it is adjustable, it is possible to gradually increase the vibration intensity depending on the improvement status of periodontal disease, and it is possible to use an appropriate and safe vibration intensity at all times.

Since the device according to the present invention does not include any mechanical drive mechanism or vibration transmission mechanism other than the vibration motor, there is no energy loss associated with motion conversion or motion transmission, no unnecessary vibration and noise, and the shape of the vibration motor Because it has an elongated cylindrical shape and is waterproof, it is easy to insert and hold it in narrow areas of the moist oral cavity along the tooth row, and the neck part of the structure is Because it is long and thin, it is easy to insert the vibration motor into the oral cavity and seal the oral cavity with the lips, making it easy to massage with the mouth closed.

The device according to the present invention is not an interdental insertion type massage device in which a vibrating body is inserted buccolingually into the interdental area, but is used in a narrow space between the teeth and the cheek or between the teeth and the tongue. , since it is easy to contact the bases of multiple interdental papillae located in the tooth neck along the tooth row running in the mesio-distal direction, and the bases of multiple interdental papillae can be massaged simultaneously. It has the advantage of being highly efficient in massaging the interdental papilla, which is a common site of periodontal disease.

In the embodiment according to Claims 1 and 2 of the present invention, in which the vibration motor inserted into the oral cavity and the vibration motor control circuit placed outside the oral cavity are connected by waterproof lead wires, the vibration It is possible to close the mouth with the motor in the mouth and massage the gums with the mouth closed.
For this reason, it is easy to swallow saliva with the mouth closed, and when massaging with the mouth open, the intraoral application part of the device is often brought out of the mouth to swallow or spit out the saliva. Because it does not drip from the mouth, it is possible to efficiently massage the periodontal tissue quietly and at any time, anywhere, while doing other activities, without causing any inconvenience to others. It is easy to increase the frequency of massage per day and increase the duration, and the faster and greater massage effects can be expected.

In the present invention, in healthy periodontal tissue, it is possible to adjust the vibration stimulation intensity to a comfortable level by operating a variable resistor, thereby promoting arterial blood flow and stimulating each part of the periodontal tissue. Delivering sufficient nutrients and oxygen to cells, activating each cell, maintaining tissue metabolic health, maintaining periodontal tissue in an aerobic environment, supporting suppression of anaerobic bacteria, and lymph flow. At the same time, it is possible to support the maintenance of healthy tissue fluid volume and composition, maintain normal metabolism and turnover of attached epithelium, and maintain healthy gingival crevicular exudate and white blood cells in a physiological manner. It can be expected to have the effect of preventing periodontal disease by supporting exudation into the grooves and promoting the function of the physiological defense mechanism of the periodontal tissue.

Since it is possible to induce or promote peristalsis of lymph vessels by lightly rubbing the surface of the skin, such manipulations are also used in cosmetic treatments and in the treatment of edema. Such operations do not affect the hemodynamics of small arteries.
In the present invention, the vibration intensity can be adjusted steplessly from the rated output state of the vibration motor to the stop of vibration using a variable resistor having an operation part, and it is possible to use vibrations that are weak enough to be detected. Therefore, when the presence of periodontal disease is suspected or when the presence of periodontal disease is clear, weak vibration stimulation can be used to suppress the action of the arterial system and stimulate the lymphatic system. It is possible to perform a massage operation that promotes the action of the system.
This prioritizes and promotes the discharge of tissue fluid that is abnormal in amount and composition from the periodontal tissue, halts the progression of inflammation, normalizes the microcirculation system and metabolism, and initiates a healing mechanism for periodontal disease. This can be expected to have the effect of encouraging people to

Vibrations have the property of being easily transmitted within bones, and vibrations applied to the gums are transmitted to the inner ear through bone conduction, and the vibration stimulation can be sensed as sound.
Therefore, with the device according to the present invention, it is possible to apply vibrational stimulation to the maxillofacial bones.
On the other hand, bone cells sense the shock applied to the bone, which has the effect of promoting bone formation in osteoblasts, and if a state of no shock continues, bone cells secrete large amounts of sclerostin. Vibration stimulation of bones is known to inhibit osteoblast division and reduce the number of osteoblasts [see Non-Patent Document 9]. Vibration stimulation of bones stimulates bone cells and promotes bone formation. Alternatively, it can be expected to suppress the secretion of sclerostin and support normal bone remodeling.
When massaging the base of the interdental papilla using the device according to the present invention, the vibration motor is positioned along the neck of the tooth, so that vibrations are also transmitted to the alveolar bone.
This can be expected to have the effect of vibrationally stimulating the alveolar bone, promoting bone formation by osteoblasts, and suppressing alveolar bone resorption due to periodontal disease.
Furthermore, vibrations generated by mastication are transmitted through the teeth to the alveolar bone, and when teeth are lost, the vibrations transmitted to the alveolar bone are thought to decrease, promoting the reduction of the alveolar bone.
Therefore, application of the present invention to areas where teeth have been lost can be expected to have the effect of suppressing alveolar bone resorption.
Furthermore, by bringing a vibration motor into direct contact with the neck of a tooth, it is possible to vibrate the tooth by a resonance phenomenon.
This supports remodeling of the alveolar bone through impulsive vibrational stimulation of the alveolar bone, and direct vibrational stimulation of the periodontal ligament increases arterial blood flow in the periodontal ligament, increasing the amount of gingival crevicular exudate produced. It is possible to conduct research on their clinical use.

Periodontal disease is chronic inflammation of the oral mucosa accompanied by alveolar bone resorption caused by bacteria, and chronic sinusitis is also chronic inflammation of the nasal turbinate mucosa caused by bacteria. The nasal turbinate mucosa, which is rich in veins and lymphatic vessels, is prone to swelling due to congestion or increased permeability of blood vessels, and the mucosa thickens, leading to nasal congestion. The state of the oral mucosa in patients with periodontal disease and periodontal disease can be considered to be similar in that they are chronic inflammation of the mucosa caused by bacteria.
Promoting lymph flow in the gums through massage is effective in preventing and treating periodontal disease. Massage aimed at promoting lymph flow in the nasal turbinate mucosa also improves inflammatory symptoms and improves the nasal mucosa. It is thought that the effect of suppressing thickening and suppressing nasal congestion can be expected.
Therefore, using the present invention, by vibrating the maxilla through the alveolar mucosa or vibrating the nasal bone through the nose, the nasal turbinate mucosa can be stimulated by the vibrational stimulation transmitted by bone conduction to the lymphatic system. It is possible to massage with a vibration intensity that mainly produces the effect of .
In the embodiment according to claim 2 of the present invention, it is easy to manufacture a device that holds the vibration motor in contact with the nose, promotes drainage of tissue fluid from the nasal mucosal tissue, suppresses thickening of the nasal mucosa, and reduces nasal congestion. It can be expected to improve or prevent nasal congestion.

In the embodiment according to claim 2 of the present invention, an impression of the upper and lower jaws is taken, and a plurality of vibration motors coated with waterproof and elastic resin are moved to the teeth of each row of teeth on the upper and lower jaw models. It is possible to manufacture a mouthpiece in which a vibration motor is fixed to the mouthpiece and is placed in contact with the base of the interpapillae. In this case, each vibration motor is connected in parallel with only one power supply unit, but in that case, a variable resistor is individually provided for each vibration motor, and each vibration motor is connected in parallel. It is also possible to control them individually.
By installing a vibration motor in the mouthpiece, you can do other tasks while wearing the mouthpiece anytime and anywhere, and massage the upper and lower jaw gums at once with a vibration intensity that suits the condition of each gum. This makes it possible to shorten the period until the effect is obtained, and the vibration motor can also be fixedly installed on a floor-type scene, which has the advantage of easy clinical application.

Although the device according to the present invention is a massage-only device that does not have any cleaning function, it can massage the gums anytime and anywhere, so when brushing your teeth in the bathroom, you only need to concentrate on removing plaque. Among the functions that an oral hygiene device should have, it is possible to clearly separate the tooth cleaning function and the gum massage function.
This will make it easier to use specialized equipment, each with its own high performance, for each function, and by using a combination of highly accurate and efficient functions, we can expect the effect of greatly improving oral health in an efficient manner.

Since the device according to the present invention does not have a mechanical drive mechanism or motion transmission mechanism other than a vibration motor, it does not generate unnecessary vibrations or sounds, and the vibration sound transmitted to the inner ear by bone conduction is monotone. It has the characteristic of causing less discomfort.
