Description

[Technical field]

[0001] The present invention relates to mouthpiece jewelry, which is a mouthpiece decorated with ornamental objects, such as gemstones. [Background technology]

[0002] In recent years, a fashion called teeth jewelry, which is artificial gemstones attached to teeth, has been gaining attention among young people. However, teeth jewelry uses adhesive to attach artificial gemstones to the surface of teeth, and there is a risk of damaging tooth enamel and causing health problems when the artificial gemstones are removed from the teeth.

[0003] Therefore, mouthpiece jewelry, a technology that imitates teeth jewelry, has been attracting attention. Generally, mouthpiece jewelry is a mouthpiece that is placed over the teeth and specially treated to attach artificial gemstones with a special adhesive. As a technology related to mouthpiece jewelry, a technique is known in which decorative false teeth, which are mouthpieces that imitate natural dentition, are provided with ornaments such as gemstones, ornaments, and precious metals (Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6434089 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the case of the device described in Patent Document 1, although a jewel is fixed to an ornamental false tooth with an adhesive, there is a risk that the jewel may come off due to deterioration of the adhesive over many years of use or due to impact. Because of this risk of the jewel coming off and being lost, it is difficult to use expensive jewelry such as diamonds or goldwork, and the range of choices of usable ornaments is narrow.

[0006] Today, the number of influencers who continuously release video works and make money using streaming platforms such as YouTube (registered trademark), Instagram (registered trademark), and TikTok (registered trademark) and the number of viewers who watch them are increasing. Influencers want decorative items that differentiate them from other influencers in order to gain more viewers and increase the number of views. For mouthpiece jewelry, if it becomes possible to use diamonds or goldwork as decorative objects, the range of items to differentiate them will increase.

[0007] The present invention was made under these circumstances, and its purpose is to provide mouthpiece jewelry that is highly durable and allows for a wide range of options for usable ornaments. [Means for solving the problem]

[0008] In order to solve the above problems, the mouthpiece jewelry of the present invention is characterized in that it comprises a base material made of a first resin sheet shaped into a tooth mold, a decorative body fixed to the surface side of the base material, and a transparent second resin sheet shaped to the surface mold of the base material and the decorative body and fixed to the surface side of the base material and the decorative body (Claim 1).

[0009] By configuring it in this way, the ornament is sandwiched while covered by the first resin sheet and the second resin sheet, so that the ornament can be prevented from peeling off from the mouthpiece jewelry, and durability can be improved. Also, because the ornament can be prevented from peeling off from the mouthpiece, expensive jewelry such as diamonds and goldwork can be used, and the range of available ornaments can be expanded. Effect of the Invention

[0010] The mouthpiece jewelry of the present invention is highly durable and allows for a wide range of options for usable ornaments. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The mouthpiece jewelry 1 according to the present invention will be described below.

[0013] (Description of mouthpiece jewelry 1) The mouthpiece jewelry 1 will be described with reference to Figs. 1 and 2. Fig. 1 shows a perspective view of the mouthpiece jewelry 1. Fig. 2 shows a cross-sectional view of the mouthpiece jewelry 1 in a state in which it is used by a user. The mouthpiece jewelry 1 is a mouthpiece decorated with an ornament 10. The mouthpiece jewelry 1 can make the user's dentition glitter or attract attention by decorating the dentition in an unusual way. The mouthpiece jewelry 1 of the present invention is mainly composed of a base material 25 (a shaped first resin sheet 20), an ornament 10, and a shaped second resin sheet 30. In addition, a dental model 5 is required to shape the base material 25.

[0014] (Explanation of the first resin sheet 20) The first resin sheet 20 will be described with reference to Figs. 2, 3, 5(a), and 5(b). Figs. 2 and 3 show cross-sectional views of the first resin sheet 20. Fig. 5(a) shows a cross-sectional view of the first resin sheet 20 before it is attached to the dental model 5. Fig. 5(b) shows a cross-sectional view of the base material 25 (first resin sheet 20) shaped into a tooth mold. The material of the first resin sheet 20 is not particularly limited as long as it is a sheet-shaped resin that is thermoplastic and can be shaped by heating, but any material that is safe for use in the oral cavity can be used. For example, polyethylene, acrylic resin, ethylene vinyl acetate resin (EVA resin), polyvinyl acetate, etc. can be used. The thickness of the first resin sheet 20 in the present invention is preferably in the range of 0.1 to 2 mm. In this embodiment, the first resin sheet 20 is a polyethylene-based plate, and a 0.5 mm thick plate is used. In order to reduce the discomfort felt when wearing the mouthpiece jewelry 1, the thickness of the mouthpiece needs to be thin, while 0.5 mm is optimal for maintaining the strength of the base material 25. The first resin sheet 20 in this embodiment is transparent, but can be colored to, for example, white or tooth color. This allows the color to be changed according to the user's preference.

[0015] (Description of Decoration 10) The ornament 10 will be described with reference to Figs. 1, 2, 5(b), and 5(c). Fig. 1 shows a perspective view of the ornament 10. Figs. 2, 5(b), and 5(c) show cross-sectional views of the ornament 10. The ornament 10 is not particularly limited in material as long as it has decorative beauty, but any material that is safe for use in the oral cavity can be used. For example, gemstones such as diamonds and rubies, artificial gemstones, gold, platinum, precious metals, etc. can be used. The shape may be not only flat but also three-dimensional. The material and shape of the ornament 10 can be selected according to the user's wishes. In this embodiment, the ornament 10 is an oval-cut (flat back side) blue sapphire (1 carat).

[0016] (Explanation of second resin sheet 30) The second resin sheet 30 will be described with reference to Figs. 2, 3, and 5(c). Figs. 2 and 3 show cross-sectional views of the second resin sheet 30. Fig. 5(c) shows a cross-sectional view of the second resin sheet 30 before it is attached to the intermediate body 27. The second resin sheet 30 is not particularly limited in material as long as it is a sheet-shaped resin that is thermoplastic and can be molded by heating, but any material that is safe for use in the oral cavity can be used. For example, polyethylene, acrylic resin, ethylene vinyl acetate resin (EVA resin), polyvinyl acetate, etc. can be used. The thickness of the second resin sheet 30 in the present invention is preferably in the range of 0.1 to 2 mm. In this embodiment, the second resin sheet 30 is a polyethylene-based plate, and a thickness of 0.3 mm is used. In order to reduce the discomfort when wearing the mouthpiece jewelry 1, it is necessary to make the thickness of the mouthpiece jewelry 1 thin, while 0.3 mm is optimal for maintaining the strength as a cover material. The second resin sheet 30 in this embodiment is transparent. This is to make it easier for third parties to visually recognize the decorative beauty of the decorative object 10.

[0017] (Explanation of dental model 5) The dental model 5 will be described with reference to Figs. 3(a) and 5(a). Fig. 3(a) shows a cross-sectional view of the dental model 5. Figs. 5(a) to (c) show cross-sectional views of the dental model 5 near the front teeth. The dental model 5 is a model that imitates the dentition and gums of a user, and is composed of a dentition region 5A and a gum region 5B. The dental model 5 is formed by acquiring 3D data of the shape of the user's intraoral cavity using an intraoral scanner, and outputting the dental model 5 based on the 3D data using a 3D printer.

[0018] <Description of the manufacturing method of mouthpiece jewelry 1> A method for manufacturing the mouthpiece jewelry 1 will be described. Fig. 4 is a flow chart showing the method for manufacturing the mouthpiece jewelry 1. In this embodiment, the base material modeling step corresponds to the flow from the dental model creating step (S1) to the base material modeling step (S4). The intermediate body forming step corresponds to the intermediate body forming step (S5). The completed body modeling step corresponds to the flow from the second resin sheet heating step (S6) to the completed body modeling step (S7).

[0019] (Explanation of the dental model creation process (S1)) The dental model creation process (S1) is a process for creating a dental model 5. An operator acquires 3D data of the intraoral shape of a person (user) who wishes to use the mouthpiece jewelry 1, which is acquired using an intraoral scanner, and outputs and forms the dental model 5 based on the 3D data using a 3D printer.

[0020] (Description of the protrusion forming process (S2)) The protrusion forming step (S2) is a step for adding and forming the protrusions 5C to the dental model 5 created in the dental model creating step (S1). The worker adds and forms the protrusions 5C at predetermined positions on the surface of the dental model 5 created in the dental model creating step (S1). The protrusions 5C are formed by forming convex portions 5C of about several millimeters using putty material or the like and hardening them. The positions at which they are formed may be any positions, but it is better to form them at positions that are difficult for third parties to see when the mouth is opened, such as the back side of the teeth or the gum position. The number of protrusions formed may be any number. In this embodiment, a total of four protrusions 5C with a height of 2 mm are formed on the inside and outside of the mouth of the gum region 5B above the left and right first premolars using putty material.

[0021] (Description of the first resin sheet heating step (S3)) The first resin sheet heating step (S3) is a step of heating and softening the first resin sheet 20. An operator sets the first resin sheet 20 in a heating device (not shown) and heats the first resin sheet 20 at a predetermined temperature, thereby softening the first resin sheet 20.

[0022] (Description of the substrate modeling process (S4)) The substrate modeling step (S4) is a step of forming the substrate 25 by forming the first resin sheet 20 into a surface mold of the dental model 5 and hardening it. FIG. 5(a) shows a schematic cross-sectional view of the first resin sheet 20 during the work of covering the surface of the dental model 5. FIG. 5(b) shows a schematic cross-sectional view of the substrate 25. When the worker sets the dental model 5 in a modeling device (not shown), the softened first resin sheet 20 covers the dental model 5, and then the first resin sheet 20 is sucked so that the first resin sheet 20 adheres closely to the surface of the dental model 5. When the first resin sheet 20 is cooled in this state, the first resin sheet 20 is formed into a surface mold of the dentition region 5A of the dental model 5 and a part of the gingival region 5B connected to the dentition region 5A, to become the substrate 25.

[0023] At this time, as explained in the protrusion forming process (S2), a total of four 2 mm protrusions 5C are formed on the inside and outside of the mouth of the gum areas 5B above the left and right first premolars using putty material on the dental model 5, so that a total of four convex portions 21 are formed on the surface side of the gum covering areas of the first resin sheet 20, as shown in Figure 3(a).

[0024] (Description of the intermediate formation step (S5)) The intermediate body forming step (S5) is a step of adhering the ornament 10 to the dentition region 5A of the base material 25 (the first resin sheet 20 shaped to the surface of the dental model 5) to form the intermediate body 27. FIG. 5(b) shows a schematic cross-sectional view of the intermediate body 27 being formed by adhering the ornament 10 to the surface of the dentition covering region of the base material 25. FIG. 5(c) shows a schematic cross-sectional view of the intermediate body 27. The worker uses an adhesive sheet (not shown) to adhere the ornament 10 to the dentition covering region of the base material 25 to form the intermediate body 27. There is no particular limitation on the adhesive sheet, but a type that can be peeled off from the ornament 10 is preferable. This can prevent the value of the ornament 10 from being damaged due to the adhesive or the like not being easily peeled off.

[0025] (Description of the second resin sheet heating step (S6)) The second resin sheet heating step (S6) is a step of heating and softening the second resin sheet 30. An operator sets the second resin sheet 30 in a heating device (not shown) and heats it at a predetermined temperature, thereby softening the second resin sheet 30.

[0026] (Explanation of the finished product modeling process (S7)) The completed body forming step (S7) is a step of forming the second resin sheet 30 into a surface mold of the intermediate body 27, hardening and bonding. FIG. 5(c) shows a schematic cross-sectional view of the work of covering the surface of the intermediate body 27 with the second resin sheet 30. When the worker sets the intermediate body 27 attached to the dental model 5 in a forming device (not shown), the softened second resin sheet 30 covers the intermediate body 27, and then the second resin sheet 30 is sucked so that the second resin sheet 30 adheres closely to the surface of the intermediate body 27. When the second resin sheet 30 is cooled in this state, the second resin sheet 30 is formed into the surface mold of the intermediate body 27 and bonded. Next, the excess portion is cut off to form the mouthpiece jewelry 1 (completed body).

[0027] At this time, as explained in the intermediate formation process (S5), a total of four convex portions 21 are formed on the front side of the gingival covering areas above the left and right first premolars of the first resin sheet 20 of the base material 25, and therefore, as shown in Figure 3 (b), a total of four concave portions 31 are formed on the back side of the gingival covering areas of the second resin sheet 30.

[0028] This completes the manufacturing process of the mouthpiece jewelry 1.

[0029] According to the mouthpiece jewelry 1 of this invention, the ornament 10 is sandwiched while covered by the first resin sheet 20 and the second resin sheet 30, so that the ornament 10 can be prevented from peeling off from the mouthpiece jewelry 1, and durability can be improved. Also, because the ornament 10 can be prevented from peeling off from the mouthpiece jewelry 1, expensive jewelry such as diamonds and goldwork can be used, and the range of choices for the ornament 10 that can be used can be widened.

[0030] In addition, the first resin sheet 20 has a convex portion 21 formed on the front side thereof, and the second resin sheet 30 has a concave portion 31 formed on the rear side thereof, and the first resin sheet 20 and the second resin sheet 30 can be fixed in a state in which the convex portion 21 of the first resin sheet 20 is fitted into the concave portion 31 of the second resin sheet 30, so that the adhesion between the first resin sheet 20 and the second resin sheet 30 can be improved. Therefore, the ornament 10 can be further prevented from peeling off from the mouthpiece jewelry 1, and durability can be improved. In addition, the first resin sheet 20 and the second resin sheet 30 can be firmly fixed without using an adhesive, and since the adhesive does not adhere to the ornament 10, it is possible to prevent the value of the ornament 10 from being damaged by the adhesive.

[0031] The present invention is not limited to the above-mentioned embodiments and examples, and the technical scope of the claims of the utility model registration includes various modified forms of the design within the scope that does not deviate from the gist of the invention.
