Description

[Technical field]

[0001] The present invention relates to a method for manufacturing a mouthpiece. [Background technology]

[0002] Patent Document 1 relates to an airway securing device that pulls the lower jaw forward to forcibly secure the airway during sleep, and a stepless adjustment device used therein. More specifically, it describes an airway securing device that allows the pull-out width of the lower jaw side attachment to be set quickly and easily to suit each patient, and a stepless adjustment device used therein.

[0003] Patent Document 2 describes a mouthpiece-type orthodontic device that uses ultrasonic vibrations, in which ultrasonic waves emitted from an ultrasonic vibrator installed inside the mouthpiece affect the movement of teeth that require correction, thereby shortening the period of orthodontic treatment, and a vibration damping section is attached to the outside of the mouthpiece that comes into contact with teeth that do not require movement, so that ultrasonic vibrations can be transmitted only to teeth that require correction.

[0004] Patent document 3 states: 、 This document describes a manufacturing device and method for a dental model for making an orthodontic mouthpiece mold, which can increase the efficiency and reduce the cost of producing a next-stage dental model (a dental model for making an orthodontic mouthpiece mold) from a current-stage dental model, and also reduce the variation in quality of the produced next-stage dental model.

[0005] Typically, there are various types of mouthpieces, including soft night guard types that protect the teeth and jaw from strain caused by teeth grinding and clenching, highly durable hard types, sports mouthguard types that prevent sudden clenching of the teeth and injury to oneself or others, orthodontic mouthpiece types, and whitening types.

[0006] Mouthpiece materials include polyethylene terephthalate, which is used in pacifiers, and polyolefins, polystyrene copolymers, EVA resin (ethylene vinyl acetate copolymer), silicone, polyethylene, polyurethane, polycaprolactone, and thermoplastic resins for sports mouthguards.

[0007] [Patent Document 1] Patent No. 4831578 [Patent Document 2] Patent No. 6253171 [Patent Document 3] Patent No. 5947969 Summary of the Invention [Problem to be solved by the invention]

[0008] Conventional mouthpieces have the following problems. Depending on the material used to manufacture the mouthpiece, there is a feeling of discomfort when wearing it in the mouth and a smell specific to the material. This unpleasant feeling is instantly transmitted to the sympathetic nerves of the autonomic nervous system, affecting human health.

[0009] Next, the mouthpiece needs to be flexible when putting it on and taking it off, but it also needs to be firm enough to apply pressure to the teeth. This can cause discomfort when the corners of the mouthpiece hit the oral mucosa, or can lead to cuts or inflammation of the oral mucosa.

[0010] Furthermore, depending on the individual, wearing a mouthpiece can cause discomfort and, as a common symptom of poor physical condition, can reduce the amount of saliva secreted from the mouth. In order to address this, it is necessary to stimulate the secretion of saliva and increase the amount of saliva secreted.

[0011] Furthermore, wearing a mouthpiece in the mouth for long periods of time can cause discomfort in daily life or during exercise, and the hassle of putting on and taking off the mouthpiece can make people dislike wearing it, resulting in problems associated with wearing the mouthpiece. [Means for solving the problem]

[0012] The method for producing a mouthpiece of the present invention is a mouthpiece sheet in which an extract taken from the plants mugwort, Japanese knotweed, and persimmon leaves is mixed into the base material of the mouthpiece sheet, and the mouthpiece is molded by taking an impression of an individual's teeth using the mouthpiece sheet, or the mouthpiece is molded without taking an impression of the teeth so that the mouthpiece can be used versatility-wise regardless of individual differences.

[0013] Furthermore, the mouthpiece sheet has a base material of polyethylene terephthalate, polyolefin, silicone, polyethylene, polyurethane, polycaprolactone, polystyrene copolymer, thermoplastic resin, or EVA resin material (ethylene vinyl acetate copolymer), and this base material is mixed with extracts collected from the leaves of the plants mugwort, Japanese knotweed, and persimmon, with the ratio of the plant extract to the base material being 1 to 20%. Effect of the Invention

[0014] The usefulness of the manufacturing method of the mouthpiece of the present invention, which leads to good physical condition after wearing the mouthpiece of the present invention by focusing on saliva as a non-invasive sample liquid and using scientifically objective numerical data, was verified in Tables 1 and 2. The use of the mouthpiece increases the secretion of saliva, and the antibacterial effect of the saliva components reduces bad breath and tooth decay. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] FIG. 1 will be described. FIG. 1 is a diagram showing a mouthpiece sheet for producing a mouthpiece of the present invention. The mouthpiece sheet 1 is a sheet having any one of a square, rectangular, circular, and elliptical shape. The shape of this mouthpiece sheet 1 is not limited to the above-mentioned shapes, and various shapes can be used. This shape can be selected according to the individual shape of the inside of the oral cavity.

[0017] The mouthpiece of the present invention is a mixture of extracts taken from plants such as mugwort, Japanese knotweed, and persimmon leaves with the base material of the mouthpiece sheet 1, and the mixture ratio is adjusted to 1-20% of the mixed plant extract with respect to the base material of the mouthpiece sheet 1. The mugwort used in the mixed plant extract has been known since ancient times to be effective in treating stiff shoulders, neuralgia, chilblains, hemorrhoids, poor circulation, lower back pain, and fatigue, and is also used as a hemostatic agent for scrapes and cuts. It is rich in tannins and flavonoids, and therefore has strong deodorizing, antibacterial, and antioxidant effects. Japanese knotweed contains polyphenols called resveratrol, which acts as an antibiotic and antibacterial agent that prevents oxidation and suppresses the progression of bacterial infection, and the reason why people have been using Japanese knotweed for food, even though it is said to be sour and unpalatable, is because it has excellent antioxidant effects. Persimmon leaves have been used since ancient times for their antibacterial and deodorant properties, and have been used to remove protein poisons from poisonous snakes and as a clarifier for alcohol. They are still used in various fields today, and are also known to have the effect of decomposing formaldehyde. Persimmon leaf tea has been drunk since ancient times as it has blood pressure lowering, diuretic and hemostatic effects. In addition, astragalin contained in persimmon leaves has been noted for its high effect against allergies. The mouthpiece of the present invention is worn in the oral cavity, and in order to maximize the effect of the solution that has these hidden benefits, focusing on the safety and effectiveness of the effects on human health that have been used as a traditional Chinese medicine for many years since ancient times, the method of extracting the solution focuses on the density of mugwort, Japanese knotweed and persimmon leaves that are the subject of plant extraction, and combines them by utilizing the difference in their boiling points, ease of solubility in solvents and differences in solubility, thereby increasing the purity of the mugwort, Japanese knotweed and persimmon leaves that are the subject of plant extraction, and the extract components, and further, the solution extracted from mugwort, Japanese knotweed and persimmon leaves is fermented.

[0018] FIG. 2 will be described. FIG. 2 is a diagram showing a mouthpiece without a dental impression as a general-purpose mouthpiece. In the bite state with the mouthpiece attached, there are a right maxillary teeth occlusal abutment portion 2 and a right maxillary teeth lingual abutment portion 3 on the right side, and a left maxillary teeth lingual abutment portion 4 and a left maxillary teeth occlusal abutment portion 5 on the left side. The right side of the part that contacts the cheek of the upper jaw is a right maxillary teeth buccal abutment portion 6, and the left side is a left maxillary teeth buccal abutment portion 7, and there is a maxillary teeth labial abutment portion 8 as a part that contacts the lips. The mouthpiece in FIG. 2 is designed to be used universally regardless of individual differences.

[0019] FIG. 3 will be described. FIG. 3 is a view showing a mouthpiece with teeth molded as a mouthpiece sheet that is matched to the wearer's tooth shape. In the bite state with the mouthpiece worn, the right side is the right maxillary teeth occlusal abutment part 9 and the right maxillary teeth lingual abutment part 10, and the left side is the left maxillary teeth lingual abutment part 12 and the left maxillary teeth occlusal abutment part 11. The right side, which corresponds to the cheek of the upper jaw, is the right maxillary teeth buccal abutment part 13, and the left side is the left maxillary teeth buccal abutment part 14, and there is an upper jaw teeth labial abutment part 15 as a part that abuts against the lips. The mouthpiece in FIG. 3 is molded by molding the teeth of each individual to absorb the individual differences of each individual.

[0020] Now, let us consider Fig. 4. Fig. 4 is a diagram showing the state in which the mouthpiece is attached to the teeth. The upper teeth 18 are located inside the upper lip 16, and the lower teeth 19 are located inside the lower lip 17. The mouthpiece 20 is carefully attached to the upper teeth 18 by placing the fingertips 21 on them.

[0021] The thickness and softness of both the general-purpose mouthpiece shown in Figure 2 and the mouthpiece tailored to individual differences shown in Figure 3 can be adjusted according to the purpose of use of the mouthpiece. For the soft type of night guard, a soft mouthpiece sheet is used and the thickness is slightly thinner. For the highly durable hard type, a soft mouthpiece sheet is used and the thickness is thicker than that of the soft type. For the sports mouthguard type, which prevents sudden clenching of the teeth and injury to oneself or others, a soft mouthpiece sheet is used to absorb shock and the thickness is even thicker than that of the hard type of night guide. For the orthodontic mouthguard type, a hard mouthpiece sheet is used and the thickness is even thicker than that of the sports mouthguard type. For the whitening type, a soft mouthpiece sheet is used and the thickness is slightly thinner than that of the soft type of night guide. In this way, the mouthpiece sheet base material and mouthpiece molding of the present invention produce mouthpiece sheets of various shapes and thicknesses, soft or hard, depending on the intended use, and then mold and manufacture the mouthpiece.

[0022] Among the five senses (hearing, sight, smell, taste, and touch) that are sensitive to the effects on human health after wearing a mouthpiece, the instantaneous reaction of smell, touch, and taste when wearing a mouthpiece in the mouth, the specific smell of the material, and the discomfort or comfort felt by the touch and taste when touching the tip of the tongue are instantly transmitted to the sympathetic and parasympathetic nerves of the autonomic nervous system. The sympathetic and parasympathetic nerves control the human body by commands from an organ in the brain called the "hypothalamus."

[0023] Now, let us consider Fig. 5. Fig. 5 is a diagram showing the structure between the reference electrode and working electrode of the human saliva ORP measuring device. The human saliva ORP measuring device 36 is provided with three measurement boxes 42 that have the same structure between the two electrodes, the reference electrode 32 and the working electrode 26. The enlarged view of the bubble shows the structure between the reference electrode 32 and the working electrode 26. The electrolyte concentration of all the saliva components and the activity ratio of oxidized and reduced substances are calculated using the two opposing reference electrodes (silver-silver chloride electrodes) 32 and the working electrode (platinum electrode or pure gold electrode) 26, and the potential difference between oxidation and reduction is measured. A minute amount of KCl solution 34 is drawn into the saliva-impregnated cotton part 23 by capillary action through the liquid junction 30, which serves as the contact point between the KCl solution 34, which exchanges positive and negative electrons of the saliva ORP between the saliva 23 impregnated in the cotton swab and the reference electrode (silver-silver chloride) 32 serving as the opposing electrode, and the saliva-impregnated, wet cotton swab 23. Positive and negative electrons are exchanged via the KCl solution 34 between the two electrodes, the reference electrode 32 and the working electrode 26, and the oxidation-reduction potential (mV) difference is calculated and the measurement result is displayed on the LCD at 39. These are the tank lid 33 for storing the KCl solution, the shaft 22 of the saliva-impregnated cotton swab, the cotton part 23 of the saliva-impregnated cotton swab, the sample tank base 24 into which the saliva-impregnated cotton swab is inserted, and the contact point 25 between the saliva-impregnated cotton swab 23 and the head part of the working electrode 26, and the working electrode 26 is fixed and adhered to the bottom 29 of the sample tank. These include a point 27 where the working electrode 26 and lead wire 28 are glued and connected, a point 31 where the reference electrode (silver-silver chloride) 32 and lead wire 28 are glued and connected, an oxidation-reduction potential mV measuring unit 35 that calculates the potential difference by the exchange of positive and negative electrons between the reference electrode 32 and working electrode 26 via a KCl solution, a start button 38 to start measurement, a measurement result print button 37, an LCD unit 39 that displays the measurement results by the oxidation-reduction potential mV measuring unit 35 that calculates the potential difference, an LCD unit 40 that displays the year and time, a thermal print 41 of the measurement results, and the configuration between the reference electrode and working electrode is provided in three measurement boxes 42.

[0024] Here, the principle and effect of the saliva ORP measuring device used to verify the effect of the present invention will be described. The principle of oxidation-reduction potential is a value that expresses the difference between the oxidizing power and reducing power of ORP (Oxidation Reduction Potential) as a potential difference. In other words, ORP expresses in mV whether a substance is in a state in which it is easy to oxidize other substances or in a state in which it is easy to reduce them, and a high positive potential usually indicates an oxidized state. A negative potential indicates a reduced state. An oxidation tendency in the body means a tendency toward inflammation, exhaustion, overwork, excessive stress, and aging factors, while a predominance of reduction means the opposite, delaying the acceleration of aging and maintaining good physical condition.

[0025] The applicant of the present invention has already applied for the following patents (e.g., Patent No. 6142122, Patent No. 6251878, Patent No. 6253171, Patent No. 6454836, Patent No. 7065236, Patent No. 7065247, Patent No. 7168816, Patent No. 7282990) which confirm the effects on human health.

[0026] In the present invention, to confirm the internal oxidation (poor physical condition) or internal reduction (good physical condition) state, instead of relying on subjective guesswork, a non-invasive sample liquid was used to measure the saliva ORP value (oxidation-reduction potential) to confirm the impact of wearing a mouthpiece on the autonomic nerves, i.e., the impact on human health, with scientifically objective numerical data. There are three places in the oral cavity where saliva comes out: the parotid gland (thin, thin saliva with a strong reduction effect), the submandibular gland (sticky saliva with a strong oxidation effect that strongly reflects stress load), and the sublingual gland (strong, sticky saliva with a strong antibacterial effect), and there are also minor salivary glands that come out from between the gums. Since the saliva secreted from the various salivary glands is concentrated in the center of the tongue, a cotton swab was placed in the mouth at this location to collect saliva and measure the ORP oxidation-reduction potential value of the saliva.

[0027] The amount of saliva secreted is said to decrease due to a variety of factors including aging and stress, and attention was paid to the fact that health effects are closely correlated with the amount of saliva secreted. The mouthpiece sheets were manufactured by mixing the EVA resin (ethylene vinyl acetate copolymer) base material used in the manufacture of mouthpiece sheets with extracts taken from mugwort, Japanese knotweed, and persimmon leaves, plants that have been used as medicinal herbs since ancient times. The mouthpieces were molded into two types: one based on an impression of each individual's teeth, and one that is a general-purpose mouthpiece that can be used by anyone regardless of individual differences, and the health effects of the saliva ORP value were visualized to confirm the effect.

[0028] In order to prevent discomfort caused by the corners of the mouthpiece placed in the mouth hitting the oral mucosa and to prevent wounds and inflammation of the oral mucosa, the mouthpiece is given a flexibility similar to that of the oral mucosa, cheek mucosa, tongue, and gums by adjusting the ratio of the plant extract mixed with the base material of the mouthpiece sheet in the process of mixing the extract from mugwort, Japanese knotweed, and persimmon leaves, which have been used as medicinal herbs since ancient times. Soft and hard mouthpiece sheets are manufactured by adjusting the thickness of the mouthpiece sheet from 1mm to 12mm, which allows the softness and hardness of the mouthpiece, the odor specific to the base material, and the shock to the oral mucosa to be absorbed and softened.

[0029] The features of various types of the mouthpiece of the present invention will be described. The soft type of night guard protects the teeth and jaw from the load caused by teeth grinding and clenching, and is molded using a soft mouthpiece sheet of the present invention with a slightly thinner thickness to reduce the internal load of the user during sleep. On the other hand, a soft mouthpiece sheet is used for molding a hard type with high durability, and is thicker than the soft type. A soft mouthpiece sheet is used to absorb shocks, and a mouthpiece sheet thicker than the hard type of night guide is used to mold the mouthpiece, and the strength of the mouthpiece can be increased. A hard mouthpiece sheet is used for molding a mouthpiece type for correction, and is thicker than the sports mouthguard type, so that the alignment of teeth can be corrected firmly. For the molding of the whitening type, a soft mouthpiece sheet is used, and the thickness is slightly thinner, similar to that of the soft type of Night Guide. The mouthpiece sheet base material and the mouthpiece molding of the present invention are selected and manufactured according to the purpose of use.

[0030] In the present invention, the mouthpiece is designed to stimulate saliva secretion. In order to make the mouthpiece material such that the feel when the mouthpiece is put in the oral cavity and the smell unique to the material are pleasant, the ratio of the extract of the plant to the base material of the mouthpiece sheet is adjusted in the process of mixing the conventional material with the extract of the plants that have been used as medicinal herbs since ancient times, such as mugwort, Japanese knotweed, and persimmon leaves, to manufacture the mouthpiece sheet, so that the mouthpiece can be put on without feeling an unpleasant feel or smell when put on.

[0031] In the present invention, the load on the body caused by wearing the mouthpiece for a long time is reduced. The mouthpiece sheet manufactured by adjusting the ratio of the plant extract mixed into the base material of the mouthpiece sheet is used to mold the mouthpiece with the teeth of each individual, or the mouthpiece molded without teeth mold, which is versatile regardless of individual differences, is worn. The results of the time-course measurement over a long period of time of 90 minutes, as shown in Table 1 below, confirmed the reduction effect of good physical condition as the effect on health caused by the ORP value of human saliva, even when worn for a long period of time of more than 60 minutes or for a short period of time of wearing for 5 minutes. Therefore, even in the problem of disliking wearing the mouthpiece because it is troublesome to put on and take off, the long-term usefulness of the mouthpiece can be demonstrated even when worn for a short period of time.

[0032] There are issues with asserting that ingredients derived from plants are safe and secure, as some plants are highly toxic and some cause allergic reactions. This point was emphasized. Incidentally, natural ingredients include natural animal and plant ingredients that have been extracted, refined, and processed through chemical processing, but the implementation data in Table 1 below is for mouthpiece sheets and molded mouthpieces manufactured by mixing natural ingredient extracts from the aforementioned plants that have been used as medicinal herbs since ancient times.

[0033] As a phenomenon of saliva secretion, when touch or taste is felt to be pleasant, the parasympathetic nerves of the autonomic nerves are relaxed, and mainly a lot of watery serous (thin) saliva is secreted from the parotid gland, as shown in FIG. 6. On the other hand, when touch or taste is felt to be unpleasant or a state of tension is felt, the sympathetic nerves become stressed, saliva secretion from the parotid gland is stopped, and mucous (sticky) saliva is secreted from the submandibular gland and sublingual gland. The ORP value of human saliva containing a lot of the watery serous (thin) saliva shows a strong negative ORP value (mV) indicating good physical condition where the body is reduced, while the ORP value of human saliva containing a lot of the mucous (sticky) saliva shows a strong positive ORP value (mV) indicating bad physical condition where the body is oxidized. Note that FIG. 6 shows the correlation between the oxidation-reduction potential (ORP) of human saliva and the autonomic nerves. Rather than simply increasing the amount of saliva secreted, wearing the mouthpiece of the present invention acts on the parasympathetic nervous system and encourages the secretion of thin saliva, a saliva component with strong reducing properties produced by the parotid gland, which leads to good health, and the mouthpiece of the present invention focuses on this point.

[0034] As a common symptom of people with chronic diseases, a pediatrician and internist who has jointly conducted clinical research on human saliva ORP with the applicant of this application has shown in Igaku-Shoin's Clinical Tests, Vol. 53, No. 7, "Clinical Tests of Saliva" that the ORP of saliva of healthy infants shows a strongly negative reduced value. Furthermore, in his book "Heaven's Consideration," which summarizes clinical studies on saliva ORP by the same doctor, it has been said that babies who drool more are healthier, and that the ORP value of saliva of healthy babies who visited the hospital during the growth observation process of regular health checkups in daily medical care clearly showed negative values, and that the health of the babies was confirmed by the correlation between visual interviews and invisible changes in the body's physical condition.

[0035] For example, musicians, athletes, or people who give long lectures often suffer from disorders that could be considered occupational diseases because they use postures, movements, or speaking skills that are not found in normal life due to the characteristics of their respective instruments, sports, or performances. By improving the oral environment, the body's center of gravity balance can be corrected and unnatural muscle and ligament tension can be eliminated, which can reduce or eliminate pain. Musicians can endure long performances and see changes in tone, while athletes can see benefits such as improved flexibility, prevention of injuries, reduced rehabilitation time, and improved performance. In addition, it is well known that saliva has six known functions: digestive, protective, lubricating, antibacterial, purifying, and buffering. In the case of people who give lectures, when the amount of saliva secreted is low, the lubricating function of saliva is inhibited when moving the jaw when eating or speaking, etc., the mucous membrane protection is reduced, the smoothness of the tongue is affected, and smooth speech, vocalization, chewing, and swallowing are inhibited.

[0036] Let me explain Figure 7. The change in internal physical condition is determined by the ORP value of human saliva. The ORP boundary limit value for human physical condition is 40-50mV, as published in the medical journal "Clinical Tests of Saliva" by Igaku-Shoin. According to this figure, the ORP value that determines good physical condition is 40mV or less, and the stronger the negative ORP value, the stronger the reduction level of saliva. The ORP value that determines poor physical condition is 50mV or more, and the stronger the positive ORP value, the stronger the oxidation level of saliva. Normally, a high positive potential indicates an oxidized state. A negative potential indicates a reduced state. An oxidizing tendency in the body means a tendency toward inflammation, exhaustion, overwork, excessive stress, and aging factors, while a predominance of reduction is the opposite, delaying the acceleration of aging and maintaining good physical condition.

[0037] (1) The manufacturing method of the mouthpiece of the present invention, which reduces oxygen in the body, was able to demonstrate the scientific and objective significance of the mouthpiece manufacturing method by measuring the ORP value of human saliva before and after wearing the mouthpiece to determine its effects on human health.

[0038] (2) In the past, confirmation of the oxidative state (poor physical condition) in the body was left to subjective guesswork. Therefore, the method of manufacturing the mouthpiece of the present invention was realized by visualizing the redox state in the body with scientifically objective numerical data using a saliva ORP measuring device for a non-invasive, stress-free sample liquid. Therefore, as shown in Tables 1 and 2, it is unlikely that the redox action shown in Table 1 was accidentally useful when tracking the time-dependent changes before and after use, or before and after wearing, as a reduction effect on the health of the human body, and the significance of the present invention was scientifically and objectively visualized by measuring the human saliva ORP value obtained by using a mouthpiece that promotes the secretion of saliva, which is the focus of the present invention. EXAMPLES

[0039] Table 1 shows the time course of changes in the redox reaction in the body over 90 minutes before and after wearing the mouthpiece of the present invention, and is based on the results of the following 12 test subjects: "Mr. A, who wore the mouthpiece for only the first 5 minutes after dental impressions were taken," "Mr. B and Mr. C, who wore the mouthpiece throughout after dental impressions were taken," "Mr. D, Mr. E, Mr. F, and Mr. G, who wore the mouthpiece for only the first 5 minutes without dental impressions, and Mr. H, Mr. I, Mr. J, Mr. K, and Mr. L, who wore the mouthpiece throughout after dental impressions were taken," which are generalized regardless of individual differences. " and the results of the verification, respectively. Except for the rare redox reaction case of Mr. B, there was no significant difference in the saliva ORP value whether the tooth mold was taken or not, or whether the tooth mold was taken for the first 5 minutes or the entire 90 minutes, and of the 12 monitors, 11 had an ORP value of 40mV or less, which is the redox boundary between good and bad physical condition before wearing, and 9 of them started the verification with a strong negative reduction value (good physical condition). As a result, in the long-term verification after 90 minutes, it was shown that all the monitors did not return to the value before wearing, and their bodies were clearly led to a strong reduction (good physical condition). In addition, in the case of Mr. L, the body, which was in a slightly oxidized (bad physical condition) state at the redox boundary of 50mV before wearing, was 27mV after 60 minutes, and after 90 minutes, it further showed 8mV in the reduction direction, clearly demonstrating the usefulness of the manufacturing method and the method of using the mouthpiece of the present invention. The data in Table 1 was produced by mixing the EVA resin (ethylene vinyl acetate copolymer) used as the base material of the mouthpiece sheet with extracts from mugwort, Japanese knotweed, and persimmon leaves, which have been used as medicinal herbs since ancient times, and molding the mouthpiece into two types: one with an individual's dental impression and one without a dental impression that can be used by anyone regardless of individual differences. The mouthpiece used for the monitor in Table 1 is a soft type night guard. The mouthpiece sheet was made of a soft material and was slightly thinner than the original thickness, and measurements were taken using a mouthpiece molded using this material.

[0040] [Table 1]

[0041] Table 2 shows the time course of changes in the body's redox reaction over a 90-minute period before and after wearing a commercially available "anti-bruxism mouthguard." The results are from the 16 subjects, including "Mr. A - H, who only wore the anti-bruxism mouthguard for the first 5 minutes," and "Mr. I - P, who wore the anti-bruxism mouthguard throughout." When comparing the ORP value changes over time before and after wearing, immediately after wearing and over 60 and 90 minutes, in the cases of Mr. A - H, who wore the mouthguard for the first 5 minutes, and Mr. I - P, who wore the mouthguard throughout, all subjects showed a negative ORP value 5 minutes after wearing the mouthguard, regardless of whether they wore the mouthguard for only the first 5 minutes or the entire time. However, the ORP value change over time for all the subjects from 30 to 90 minutes showed a positive value in the oxidative direction from the ORP value before wearing, and the ORP value of human saliva after wearing the mouthpiece was shown to be oxidative, regardless of whether the bruxism mouthguard was worn for only the first 5 minutes or the bruxism mouthguard was worn throughout the entire time. The measurement results shown in Table 2 clearly showed a difference from the human saliva ORP value shown in Table 1 when the mouthpiece of the present invention was worn.

[0042] As described above, when the mouthpiece of the present invention shown in Table 1 was worn, the saliva ORP value showed a value on the reduction potential side compared to when the conventional commercially available mouthpiece shown in Table 2 was worn, indicating better physical condition.

[0043] [Table 2] [Industrial Applicability]

[0044] In the present invention, the mouthpiece of the present invention, which is made of a mixture of the extracts of the plants mugwort, Japanese knotweed, and persimmon leaves, is worn on the base material of the mouthpiece sheet, and the human body feels comfortable, which activates the parasympathetic nerves, and the saliva with strong reducing action is abundantly secreted. As for the benefits of saliva components, the common feature of healthy people from infants to the elderly is that, especially in infants, many healthy infants are in a state of drooling a lot, and even in the elderly, the secretion of smooth saliva in the oral cavity is abundant, which makes conversation smoother, and the antibacterial action of saliva components prevents bad breath, prevents tooth decay, and improves physical condition, and the usefulness was confirmed by tracking the change in human saliva ORP value over time after the mouthpiece is worn. Therefore, it is believed that it will greatly contribute to the improvement of daily life habits and health life expectancy of people. [Explanation of symbols]
