Description

[Technical field]

[0001] The present invention relates to a mouthpiece used for the prevention and treatment of periodontal disease. [Background technology]

[0002] Patent Document 1 describes an invention for preventing and treating periodontal disease using oxygen nanobubble water or ozone nanobubble water, which describes a bubble mouthwash and a bubble mouthwash method that uses a bubble aqueous solution containing more than 5,000 bubbles per ml made of air or oxygen with diameters of 10 nano to 300 microns or less, and a mouthwash containing a drug for preventing periodontitis and pyorrhea, in order to clean the gums, spaces between the teeth, etc.

[0003] However, even though Patent Document 1 describes the prevention and treatment of periodontal disease using oxygen nanobubble water or ozone nanobubble water, the bubble mouthwash method does not use a mouthpiece.

[0004] Furthermore, Patent Document 2 describes an invention for preventing and treating periodontal disease using a mouthpiece, in which hydrophilic fibers such as polyvinyl alcohol (PVA) fibers are incorporated into a support such as a resin, so that the mouthpiece fits to, holds, and is fixed to the dentition simply by fitting it into the dentition or pressing it against the teeth with the fingers.

[0005] However, even though Patent Document 2 describes the prevention and treatment of periodontal disease using a mouthpiece, it does not mention using oxygen nanobubble water or ozone nanobubble water as a moisture-retaining material in a U-shape that comes into contact with the dentition and gums.

[0006] Furthermore, as a molded mouthpiece, Patent Document 3 describes a mouthpiece body made of a thermoplastic resin consisting of a first thermoplastic resin layer and a second thermoplastic resin layer, in which the dentition and gums are molded by intraoral impression, and the edge portion of the mouthpiece body is placed in close contact with the gums and a liquid absorbing and retaining layer is provided on the inside.

[0007] However, even though Patent Document 3 describes the prevention and treatment of periodontal disease using a mouthpiece equipped with a liquid-absorbing and retaining layer, it does not mention that the liquid-absorbing and retaining layer is exposed inside the oral cavity and a moisture-retaining material containing oxygen nanobubble water or ozone nanobubble water is used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The water-retaining material of the present invention refers to a porous body having continuous pores that contains a hydrophilic material such as polyvinyl alcohol (PVA) resin, a nonwoven fabric, or a sponge and is immersed in oxygen or ozone nanobubble water. In this way, a water-retaining material containing oxygen or ozone nanobubble water can be formed into a U-shape that contacts the dentition and gums, leaving at least a portion exposed, thereby providing a mouthpiece that can be worn on the dentition and gums.

[0015] (Effects of wearing the mouthpiece of the present invention) 1 shows mouthpieces 11, 12, 13, 14 worn on the upper and lower sides of dentition A and gums B, but they may be worn only on the upper or lower sides of dentition A and gums B. These mouthpieces 11, 12, 13, 14 are made of a moisture-retaining material containing nanobubbled water of oxygen or ozone, and are U-shaped with the inner surface 3 in contact with the dentition and gums. By wearing them on dentition A and gums B with at least a portion exposed in the oral cavity, oxygen or ozone penetrates the surfaces of the teeth, the gaps between the teeth, and the gaps between the teeth and gums, suppressing the generation of bacteria on the surfaces of the teeth, the gaps between the teeth, and the gaps between the teeth and gums.

[0016] (Moisture retention of the mouthpiece of the present invention) The mouthpieces 11, 12, 13, and 14 are made of a water-retaining material 1 having nanobubbles of oxygen or ozone, and the water-retaining material 1 is made of a porous body with continuous pores by containing hydrophilic materials such as polyvinyl alcohol (PVA) resin, nonwoven fabric, or sponge. The water-retaining material 1 having nanobubbles of oxygen or ozone is obtained by immersing the water-retaining material in nanobubbles of oxygen or ozone. In the water-retaining material 1 having nanobubbles of oxygen or ozone, the nanobubbles of oxygen or ozone tend to scatter in the air, so it is necessary to take care to use the water-retaining material 1 while the nanobubbles of oxygen or ozone are still remaining. In this case, the nanobubbles of oxygen or ozone are made of Sigma Oxygen Water (registered trademark) or Sigma Ozone Water (registered trademark) manufactured by Sigma Technology Co., Ltd., and the nanobubbles of oxygen or ozone are made of fine bubbles in a nanobubble state with a particle size of 200 nm or less by a micro-nanobubble generator using water hammer force described in Patent No. 5555892 of the same company. In this way, since at least a portion of the water retention material 1 having oxygen nanobubble water in the mouthpieces 11, 12, 13, and 14 is exposed within the oral cavity, the oxygen from the oxygen nanobubble water penetrates into the surfaces of the teeth, the gaps between the teeth, and the gaps between the teeth and the gums, suppressing the growth of bacteria on the surfaces of the teeth, the gaps between the teeth, and the gaps between the teeth and the gums, and the oxygen in the oxygen nanobubble water can replenish the decrease in oxygen concentration caused by saliva. Since at least a portion of the water retention material 1 having ozone nanobubble water in the mouthpieces 11, 12, 13, and 14 is exposed within the oral cavity, the ozone from the ozone nanobubble water penetrates into the surfaces of the teeth, the gaps between the teeth, and the gaps between the teeth and the gums, suppressing the growth of bacteria on the surfaces of the teeth, the gaps between the teeth, and the gaps between the teeth and the gums, and can also eliminate bacteria in the oral cavity, providing more useful effects than water retention materials that do not have oxygen or ozone nanobubble water.

[0017] (Embodiment 1 of the mouthpiece) 2(a) and (b) show a first embodiment of the mouthpiece, and 11 is a mouthpiece that is worn from the dentition A to the gums B. This mouthpiece 11 is obtained by soaking a sheet-like water retention material 1, which is a porous material with continuous pores and is made of a hydrophilic material such as polyvinyl alcohol (PVA) resin with a thickness of 2 to 3 mm, nonwoven fabric, or sponge, in a state where it is immersed in oxygen or ozone nanobubble water, pushing it into the oral cavity in the direction P with fingers, fitting it into the dentition A, and using lips and tongue to form it into a U-shaped shape with the inner surface 3 in contact with the dentition and gums. In this mouthpiece 11, the water retention material 1 is exposed in the oral cavity, and oxygen or ozone is present, so that the oxygen in the oxygen nanobubble water can replenish the oxygen concentration reduced by saliva, and the ozone in the ozone nanobubble water can eliminate bacteria in the oral cavity.

[0018] (Embodiment 2 of the mouthpiece) 3(a) and (b) show a second embodiment of the mouthpiece, and 12 is a mouthpiece that is worn from the dentition A to the gums B. This mouthpiece 12 has a plastic deformation member 2 on the outer surface of a sheet-like water retention material 1 that is a porous body with continuous pores and contains a hydrophilic material such as polyvinyl alcohol (PVA) resin or a nonwoven fabric or sponge with a thickness of 2 to 3 mm, and is obtained by pushing the water retention material 1 in the oral cavity in the direction P with a finger while it is immersed in nanobubble water of oxygen or ozone and fitting it into the dentition A, thereby forming it into a U-shaped shape with the inner surface 3 in contact with the dentition and gums. This plastic deformation member 2 is a film with a thickness of about 1 mm made of thermoplastic resin such as polypropylene (PP) resin or polyvinyl chloride (PVC) resin that is smaller than the surface area of ​​the water retention material 1 and is attached to the outside of the water retention material 1, but it may also be a coating film that attaches thermoplastic resin particles such as polypropylene (PP) resin or polyvinyl chloride (PVC) resin to the outer surface of the water retention material 1. When forming this mouthpiece 12, the water retention material 1 having the plastic deformation member 2 is immersed in oxygen or ozone nanobubble water, and the plastic deformation member 2 is pushed into the oral cavity in the direction P with fingers and fitted into the dentition A to form a U-shaped shape that contacts the dentition and gums, so that the work of maintaining the shape that contacts the dentition and gums with the lips and tongue is reduced compared to the mouthpiece 11 in the embodiment 1 of the mouthpiece that does not have the plastic deformation member 2. In this case, the end 4 of the water retention material 1 is exposed in the oral cavity as shown in the figure, but if the material of the plastic deformation member 2 is made of a film of the thermoplastic resin, if a plurality of through holes are formed in the film (not shown), the water retention material 1 is exposed more in the oral cavity, and the oxygen or ozone of the preservative 1 is also present on the outer surface of the mouthpiece 12 through the through holes of the plastic deformation member 2, so that the oxygen of the oxygen nanobubble water replenishes the oxygen concentration reduced by saliva, and the ozone of the ozone nanobubble water can eliminate bacteria in the oral cavity, as in the mouthpiece 11.

[0019] 4(a) and (b) show a third embodiment of the mouthpiece, and 13 is a mouthpiece that is molded and placed around the dentition A to the gums B. This mouthpiece 13 is prepared by preparing a molded product having a thickness of 2 to 3 mm, which is molded into a U-shape with the inner surface 3 in contact with the dentition and gums, using a hydrophilic material such as polyvinyl alcohol (PVA) resin or a porous material with continuous pores obtained by incorporating nonwoven fabric or sponge into the material, and then immersing the molded product in nanobubble water of oxygen or ozone to expose the water-retaining material 1 in the oral cavity. In this case, the molded product that becomes the mouthpiece 13 expands when immersed in nanobubble water of oxygen or ozone, so that the molded product is molded with the depth D and width L from the dentition A to the gums B set so that the molded product will have a shape that fits around the dentition A while taking into consideration the expansion. The depth D and width L may be set by molding the shape of the smallest tooth in the dentition A so that the molded product can be fitted around the other larger teeth. In this way, the moisture retention material 1 in the mouthpiece 13 is exposed in the oral cavity, where oxygen or ozone is present, so that the oxygen in the oxygen nanobubble water replenishes the oxygen concentration reduced by saliva, and the ozone in the ozone nanobubble water can eliminate bacteria in the oral cavity.

[0020] (Embodiment 4 of the mouthpiece) 5(a), (b) and (c) show a fourth embodiment of the mouthpiece, and 14 is a mouthpiece that has been molded and worn from the dentition A to the gums B. This mouthpiece 14 is obtained by preparing a plastically deformable member 2 that is molded in a U-shape into the shape of the dentition and gums using a film of about 1 mm thickness made of a thermoplastic resin such as polymethyl methacrylate (PMMA) resin, polypropylene (PP) resin or polyvinyl chloride (PVC) resin, and by placing a water-retaining material 1 that is immersed in oxygen or ozone nanobubble water, molded from a hydrophilic material such as polyvinyl alcohol (PVA) resin or a porous body with continuous pores containing a nonwoven fabric or sponge, inside this plastically deformable member 2, and having a thickness of 2 to 3 mm, in a U-shape with an inner surface 3 in contact with the dentition and gums, and with an end 4 exposed. 5(c), the water retention material 1 in this mouthpiece 14 is exposed at the end 4 in the oral cavity where oxygen or ozone is present, so that the oxygen in the oxygen nanobubble water replenishes the oxygen concentration reduced by saliva, and the ozone in the ozone nanobubble water can eliminate bacteria in the oral cavity. In this case, the water retention material 1 is placed inside the plastic deformation member 2, so that, although not shown, when the film is molded into a U-shape into the shape of the teeth and gums, it is molded so that there is a space inside the plastic deformation member 2 where the water retention material 1 is placed. In this way, the water retention material 1 of mouthpiece 14 has on its outer surface a plastically deformable member 2 molded into the shape of the dentition and gums, and is formed in a U-shape that contacts the dentition and gums.In mouthpiece 13 of embodiment 3, which is a mouthpiece that does not have a plastically deformable member 2, the water retention material 1 expands when immersed in oxygen or ozone nanobubble water, so it was necessary to set the depth D and width L from the dentition A to the gums B to a shape that fits into the dentition A while taking into consideration this expansion.In mouthpiece 14, however, the shape molded into the shape of the dentition and gums is maintained by this plastically deformable member 2.In this case, if a plurality of through holes (not shown) are formed in the molded plastically deformable member 2, the oxygen or ozone in the preservative 1 will be present not only at the end 4 but also on the outer surface of the mouthpiece 14 through the through holes in the plastically deformable member 2, so that the oxygen in the oxygen nanobubble water in the oral cavity will replenish the oxygen concentration reduced by saliva, and the ozone in the ozone nanobubble water can improve the function of eradicating bacteria in the oral cavity. Note that, since the plastically deformable member 2 is molded to the shape of the dentition and gums, if the end 4 of the water-retaining material 1 is exposed, the thickness of the film of the plastically deformable member 2 may be set large, or the plastically deformable member 2 may be made of a two-layer film, taking into consideration the thickness and material of the water-retaining material 1 to be placed inside the plastically deformable member 2.
