Abstract

PROBLEM TO BE SOLVED: To solve problems in which it is impossible that an effect still lasts even if getting up in the morning and the inside of the mouth is in a neat state because the duration of cool feeling by mouth rinse using mouth-wash is extremely short, accordingly, whether or not the sterilizing effect and refreshing feeling may last during sleeping.SOLUTION: Then, in the present invention, a mouthpiece fitted to a patient's dentition is made, and mouth-wash is applied in this and worn to the dentition. As a result, the mouth-wash rarely comes to idly flow into the inside of the mouth, and thereby sterilizing effect and refreshing feeling are made to last for a night. Because it is desired to be provided at lower cost for producing the mouthpiece adapting to the patient's dentition like this, a method is provided for enabling this to be conducted by the patient oneself in the stage of tooth shaping.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a mouthpiece that can sterilize teeth and mouth mainly by using a mouthwash with a mouthwash on the inside at bedtime.

  It is known that germs can easily propagate in the mouth during sleep. It has been found that germs propagate even when the tongue recedes toward the throat and does not reach the upper jaw. The propagation of miscellaneous bacteria can cause strong halitosis, tooth decay and periodontal disease.

  Johnson & Johnson's Listerin (both registered trademarks) is particularly famous as a mouthwash (which is called dental rinse, mouthwash, etc.) that suppresses the propagation of germs in the mouth and sterilizes them. It can be seen that if the mouth is rinsed before going to bed, the sticky feeling in the mouth is removed and refreshed.

  However, the duration of the refreshing sensation by such mouth rinsing is extremely short, and it cannot be said that the effect is still maintained even when waking up in the morning and the mouth is refreshed. Accordingly, it is an object of the present invention to solve such a problem and to be able to maintain a bactericidal effect and a refreshing feeling even while sleeping.

  Therefore, in the present invention, a mouthpiece that fits perfectly with the patient's dentition is made, and a mouthwash is applied to the mouthpiece to be attached to the dentition. As a result, the mouthwash liquid was less likely to flow out into the mouth, and the effect of sterilization and a refreshing feeling lasted overnight. In order to manufacture such a mouthpiece that fits the patient's dentition, it may be desired to provide it at a lower price, and this is done to the patient himself (user himself) at the stage of taking the tooth shape (impression). I thought it would be good to have them.

  Accordingly, the first aspect of the present invention provides a first step in which a user takes a female tooth mold by biting a mold material having a thickness of about several millimeters, and the female tooth mold is filled with a mold material such as gypsum. Mouthpiece through a second step of creating a male tooth mold and a third step of obtaining a shallow mouthpiece made of a touch-sensitive material such as silicone using the male tooth mold. It was set as the manufacturing method of this. This mouthpiece is to be crowned about 2 mm at the tip of the tooth. A thermoplastic resin or the like may be arbitrarily used for the mold material. In addition, the shape may be a substantially U shape that matches the shape of the dentition, or a shape in which the inner side of the substantially U shape is continuous. A handle portion may be provided for easy handling. This first step is performed by the patient himself, and other steps following this are performed at the dental clinic side. The mouthpiece thus obtained is covered with a dentition after the mouthwash is coated with a mouthwash. In this way, the mouthwash stopped between the mouthpiece dent and the teeth, and was less likely to flow out into the mouth, and the bactericidal effect and cleanliness persisted during sleep. It is more preferable that the mouthwash is in a gel form.

  In the invention of claim 2, a first step of filling a tray with a mold taking agent, and a second step of biting a portion of the tray filled with the mold taking material and taking a female tooth mold by the user himself / herself, A third step of creating a male tooth mold by filling the female tooth mold with a mold material such as gypsum, and obtaining a mouthpiece made of a good material such as silicone using the male tooth mold It was set as the manufacturing method of the mouthpiece which passes through a 4th process. Of these, the second step is performed by the patient himself, and other steps before and after this are performed at the dental clinic side. The shape of the dental tray is preferably a substantially U shape that matches the shape of the dentition. When the inside of the substantially U-shape is connected to the land, there is almost no deformation of the tray when the user bites the mold taking material packed in the tray. Further, the tray is preferably provided with a handle portion so that it can be easily handled. An alginate impression material, an agar impression material, or the like may be arbitrarily used as the mold material. The mouthpiece is deeper than that of the first aspect and preferably covers the interdental papilla. That is, if a mouthwash is applied to the depression of the mouthpiece and then put on the dentition, the sterilizing effect and refreshing feeling of the mouthwash can be exerted on the hourglass-shaped gap and periodontal pocket. In addition, the mouthwash is less likely to stop between the mouthpiece dent and the teeth and flow out into the mouth. It is more convenient if the mouthwash is in a gel form.

  In the invention of claim 2, by using a vacuum former, it is possible to obtain a mouthpiece that fits the dentition and each tooth. In both the first and second aspects of the present invention, a thin paper piece may be attached to the teeth, and then a female tooth shape may be obtained using a mold material. As a result, when the mouthpiece is placed on the dentition, the mouthwash adsorbing paper made by adsorbing the mouthwash on the piece of paper can be placed between the dentition and the mouthpiece, and the mouthwash can be kept for a long time. It becomes possible to stop at the mouthpiece. Still further, a whitening agent and a dentifrice may be used together with the mouthwash. For example, provided as a mouthwash for mouthpieces, in which a gel layer of mouthwash and a gel layer of whitening agent or a dentifrice gel layer are packed side by side. To do. In any case, the effect of the mouthwash is exerted while sleeping.

  By the way, the present invention has a bactericidal effect because the duration of the refreshing sensation by the conventional mouth rinsing is extremely short and the effect is still sustained even when waking up in the morning and the mouth is in a clean state. The challenge is to maintain a refreshing feeling during sleep. For this purpose, the inventor considered that the mouthpiece needed to hold the mouthwash firmly until morning.

  Accordingly, in the final step of obtaining a mouthpiece using the male tooth mold, the invention of claim 3 is a two-layered mouse in which the inner layer is made of an open-cell foam material using the male tooth mold. Provided is a method of manufacturing a mouthpiece characterized by obtaining a piece. According to the mouthpiece obtained by this manufacturing method, the inner layer of the open-cell foamed material such as a sponge of the two-layered mouthpiece holds mouthwash and holds it firmly until morning, and the outer layer is this It will protect the state. According to the comparison between the case where the inner layer is present and the case where the inner layer is not present, the result that the holding power of the mouthwash liquid is stronger when the inner layer is present is obtained. In the case where the manufacturing method of the invention of claim 3 is adopted, it is not necessary to adopt the manufacturing method in which the above-described thin paper piece is attached to the teeth and then the female tooth mold is taken with the mold taking material. This is because the invention of 3 can sufficiently replace this.

  According to the present invention, the mouthpiece that fits the patient's dentition and teeth is made, and the mouthwash is applied to the mouthpiece so that the mouthwash flows wastefully into the oral cavity. There is an effect that the sterilization effect and the refreshing feeling are maintained even while sleeping. In addition, a mouthpiece with a two-layer structure consisting of an open cell foam material was made on the inner layer, and mouthwash was applied to the mouthpiece so that it was attached to the dentition. And the outer layer protects this state, so that the holding power of the mouthwash becomes stronger. The tooth shaping process is not a medical practice by having the patient do this, and the mouthpiece can be provided at a lower price, which is also appreciated by the patient.

  It is explanatory drawing which looked at the mouthpiece 1 of Example 1.   FIG. 3 is an explanatory view showing a part of the mouthpiece 1 in cross-section.   It is explanatory drawing of the manufacturing method of the mouthpiece.   It is explanatory drawing of the sterilization method using the mouthpiece.   6 is an explanatory diagram of a tray 3 used in the manufacturing method of Example 2. FIG.   FIG. 6 is an explanatory view in perspective of Example 2.   6 is an explanatory diagram of a method for manufacturing the mouthpiece 6. FIG.   It is explanatory drawing of the sterilization method using the mouthpiece.   It is explanatory drawing of the mouthwash gel of Example 3. FIG.

  The mouthpiece 1 of this embodiment will be described with reference to FIGS. The mouthpiece 1 has a fitting portion 10 that fits a tooth and a dentition, and is formed so that a portion 2 mm from the meshing surface becomes a lip portion 11. That is, a thermoplastic resin sheet having a thickness of several millimeters that has been warmed and softened with hot water is given to the patient and chewed as the patient's own action (step S1). When the female mold is cured, the clinic side Then, gypsum is filled and cured to make a male tooth mold (step S2). Subsequently, the male mold is used to form the inner layer 12 made of urethane foam resin, and the inner layer 12 is further formed on the inner layer 12. The outer layer 13 made of silicone resin is formed so as to cover it, and the mouthpiece 1 is manufactured (step S3). That is, the mouthpiece 1 has a two-layer structure (FIG. 2). The patient uses the mouthpiece 1 manufactured as described above, and the mouthwash gel 2 is applied to the fitting portion 10 from the mouth edge 11 side (step S4). Is placed on the dentition and pressed against the teeth T one by one with the fingertips (step S5), and the user goes to sleep and keeps wearing until morning (step S6). . The mouthwash gel 2 is conveniently held by the inner layer 12 in the fitting portion 10 for a long time.

  Naturally, the mouthpiece 1 fits snugly into the patient's teeth and dentition, and the mouthwash gel 2 is not only exposed to the teeth T but also between the teeth, the hourglass space and the periodontal pocket. Has a bactericidal action. Moreover, the mouthwash gel 2 is less likely to flow out into the oral cavity due to the above-mentioned fitting, and further, the inner layer 12 made of urethane foam resin holds the mouthwash gel 2 well until morning, and has a bactericidal effect and a refreshing feeling. It lasts from bedtime to morning. The mouthwash gel 2 is formed by gelling the mouthwash using a gelling agent. In addition, since the surface of the foamed urethane resin is porous, it also relates to the difficulty of slipping between the mouthpiece 1 and the teeth T.

  The mouthpiece 6 of this embodiment will be described with reference to FIGS. The mouthpiece 6 has a fitting portion 60 that fits a tooth and a dentition, and is formed to have a depth that can cover a range beyond the interdental papillary contact portion 61 from the meshing surface. For this purpose, the tray 3 is used as a tool for allowing the patient himself to take a female tooth shape. That is, the alginate impression material 4 is first kneaded into the substantially U-shaped groove of the tray 3 on the clinic side (step S7), and then handed over to the patient as the patient's own action of the alginate impression material 4 of the tray. The part is chewed to take the tooth mold (step S8). When the female mold is hardened, the clinic side fills it with gypsum 5 and hardens it to make a male tooth mold (step S9). A mouthpiece 6 in which silicone resin is injected and hardened is manufactured (step S10). The patient uses the mouthpiece 6 made in this way, and the mouthwash 20 is injected into the fitting portion 60 from the interdental papillary contact portion 61 side (step S11), and the mouse. The piece 6 is placed on the dentition and pressed against the teeth one by one with the fingertips (step S12). Then, the user goes to sleep and keeps wearing until getting up (step S13). .

  Thus, the mouthpiece 6 fits snugly into the patient's teeth and dentition, and the mouthwash 20 has a bactericidal action not only on the exposed parts of the teeth but also between the teeth, the hourglass space and the periodontal pocket. It affects. In addition, since the fitting part 60 is formed deeply, the mouthwash 20 is less likely to flow into the oral cavity when it is fitted to the teeth and the dentition. Therefore, the bactericidal effect and the refreshing feeling last from bedtime to morning.

  Still, when it is desired to ensure that the mouthwash 20 is retained, or when it is desired to increase the duration of the mouthwash 20, for example, the following may be performed. That is, when the patient himself takes the female tooth shape in step S8, a piece of paper having the same shape as the mouthwash adsorbing paper 7 described later is applied to the meshing surface of the tooth row, and then the alginate impression material 4 of the tray 3 is placed. Chew the part and take its tooth pattern. Then, in the mouthpiece 6 obtained in step S <b> 10, a gap corresponding to the piece of paper is formed in the innermost part of the fitting portion 60. The mouthwash adsorbing paper 7 can be accommodated in this gap, that is, a groove (portion shown by a chain line in FIG. 6).

  In this usage, when the mouthwash 20 is injected into the fitting part 60 from the interdental papillary contact part 61 side (step S14), the mouthwash 20 is applied to the innermost part of the fitting part 60. It is absorbed by the stored mouthwash adsorbing paper 7. Thereafter, the above steps S12 to S13 are performed. Since the mouthwash 20 gradually oozes from the mouthwash adsorbing paper 7, there is an advantage that the sustaining effect is high. From another point of view, the mouthwash 20 is lost in a short time just by attaching the mouthwash adsorbing paper 7 containing the mouthwash 20 to the dentition. It can be said that since the adsorbing paper 7 is covered with the mouthpiece 6, the duration of the mouthwash 20 is long.

  The above is a usage method in which the mouthwash adsorbing paper 7 is placed in the fitting portion 60 to absorb the mouthwash solution 20, but there are other usage methods. Although not shown in the figure, the mouthwash is formed in an elongated tape shape so that it fits in the fitting portion 60. Therefore, in this case, there may be an idea that the mouthwash 20 is not used. In addition, like what was demonstrated in Example 1, it can also comprise so that a mouthwash can be included in an inner layer by making a fitting part into a double structure. In this case, since there is no need to use separate parts such as the mouthwash adsorbing paper 7, the advantage of daily use, which is easy and inexpensive, is greater.

  The mouthwash gel containing a tube used for the mouthpiece of the present invention will be described with reference to FIG. The mouthwash gel tube 8 is composed of two rooms whose interiors are independent up to the mouth 80 (not shown). One room is filled with a mouthwash gel 81 and the other room is filled with a whitening gel 82. The whitening gel 82 is a gelled whitening agent. Instead of the whitening gel 82, it is possible to fill a gelling dentifrice.

  Then, when the mouthwash gel tube 8 is squeezed, the mouthwash gel 81 and the whitening gel 82 are squeezed out side by side from the mouth portion 80. At this time, the mouthwash gel 81 and the whitening gel 82 are joined at the mouth portion 80. There are two layers. Each of the effects is exerted on the mouth during sleep.

  The present invention can be sufficiently applied to a mouthpiece other than a mouthpiece that sterilizes teeth and mouth. It can also be used in the toy field.
