Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a model for practice of brushing teeth, and more particularly, to a model for practice of brushing teeth which enables anyone to practice brushing effectively.

[0002]

2. Description of the Related Art A plaque-finding dentifrice which is of interest to the present invention is disclosed, for example, in Japanese Utility Model Laid-Open No. 6-10334.

[0003] This publication discloses a toothbrush in which plaque can be easily found by applying a plaque-finding dentifrice prepared by combining a dentifrice and a plaque-finding agent to a plaque-removing toothbrush and brushing the teeth. .

[0004]

A conventional apparatus for easily determining the removal of plaque has been constructed as described above. Although it is easy to find the place where the plaque remains, in the conventional brushing practice device, after dyeing, the mouthwash is 1-2 times.
It was necessary to go around and wash away excess dye,
Such an effect cannot be known without actually brushing one's own teeth in a mirror or a place with water.

[0005] On the other hand, in schools, homes, dental clinics, and the like, students and patients sometimes practice brushing. In such a case, it was difficult to practice without specific facilities such as a mouthwash facility.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a tooth brushing practice model that enables effective brushing practice for anyone to remove plaque anywhere. And

[0007]

A tooth brushing practice model according to the present invention includes a jaw model or a dentition model having a plurality of teeth, and an adhering material instead of plaque on the surface of the plurality of teeth. An alternative to fouling includes means for indicating the effect of the repetitive brushing force when applied by the toothbrush.

According to the present invention, when the teeth of the jaw model or the dentition model are brushed with a toothbrush, the effect of whether or not the teeth are brushed by the repetitive brushing force is displayed. You can know immediately. In addition, since the teeth of the jaw model or the dentition model are provided with attachments instead of plaque, facilities such as a mirror and water are not particularly required.

Therefore, it is possible to provide a toothbrushing practice model that enables anyone to easily and effectively practice brushing anywhere.

Preferably, the deposit is a pressure-sensitive material utilizing microcapsules. Since the attached matter is a pressure-sensitive material using microcapsules, the capsules are usually broken without discoloration or falling off only when the force of repeated brushing by the toothbrush is applied to exhibit a predetermined effect. Therefore, it can be easily known whether or not the toothbrush has been polished well.

[0011] The deposit may be a colored material that falls off when the force of repetitive brushing is applied. The coloring material falls off when the repetitive brushing force of the toothbrush is applied, so that it can be easily known whether or not the toothbrush has been polished better.

[0012] More preferably, the dental arch model includes a plurality of teeth, and the plurality of teeth are arranged in a straight line or in an arc shape larger than a normal arrangement.

The teeth provided on the dentition model are arranged in a straight line, instead of the normal arrangement of human teeth. By exchanging the dental arch model, the same practice can be performed for each tooth a plurality of times.

[0014] More preferably, the means for displaying the effect of the action is a dye or a fragrance contained in the microcapsule.

The use of dyes and fragrances according to the taste of the user makes it possible to attract the user's interest in brushing. In addition, by combining a dye or a fragrance with a dentifrice or the like in a specific market, it can be used for advertising the product.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1A is a plan view of a jaw model according to one embodiment of the present invention, and FIG. 1B is a cross-sectional view of a portion indicated by IB-IB in FIG. 1A. Referring to FIG. 1, a jaw model 10 has a plurality of teeth 1 in a normal human tooth arrangement.
1 are provided adjacent to each other in a usual manner.

The jaw model 10 may be a gypsum model whose base is made of gypsum, a plastic model whose base is formed of plastic, or a pressed paper model. Various layers to be described are provided.

FIG. 2A is an enlarged schematic view showing a cross section of the surface of the tooth 11 at a portion indicated by line IIA-IIA in the jaw model 10 shown in FIG. With reference to FIG.
The surface of the tooth 11 is provided with a layer 12 of microcapsules containing a dye 14 and a layer 13 of a color developer for coloring the dye 14 contained in the layer 12 of microcapsules.

Here, the teeth 11 and the layer 13 of the developer and the layer 12 of the microcapsules are adhered with a predetermined binder to form the jaw model 10.

Next, a procedure of brushing practice using the jaw model 10 will be described. A person who practices brushing brushes the tooth surface of the jaw model 10 on which the microcapsule layer 12 and the developer layer 13 are applied with a toothbrush (not shown). When the bristle tip of the toothbrush directly contacts the teeth 11 of the jaw model 10 and a repeated brushing force acts on the teeth 11, the microcapsules 12a contained in the microcapsule layer 12 are destroyed, and the dye contained therein is thereby destroyed. 14 covers the surface of the tooth 11. The dye 14 reacts with the color developing material 15 constituting the color developing agent layer 13 to display a predetermined color. That is, in the jaw model 10, the portion of the tooth 11 directly contacted by the toothbrush is dyed with a predetermined dye color on the surface of the tooth 11, so that it is immediately known whether or not the toothbrush is properly brushed. Can be.

Here, as the microcapsules 12a, for example, a microcapsule containing a water-soluble substance disclosed in Japanese Patent No. 2851302 is preferable. FIG. 3 is a diagram showing the composition of such a microcapsule. As shown in FIG. 3, a desired color such as blue or red can be selected as the dye.

The breaking strength of the microcapsule can be changed by changing the size of the microcapsule or the strength of the wall surface of the microcapsule. Therefore, if the color of the coloring agent included in the microcapsules is made different depending on the size of the microcapsules or the strength of the microcapsules, a change in color appears due to the strength of the brushing force of the toothbrush, and the cleaning force is appropriate. You can easily see if it is.

In FIG. 2A, a developer layer 13 is provided on the teeth 11, and a microcapsule layer 12 is provided thereon.
However, the present invention is not limited to this, and a layer in which the developer 15 and the microcapsules 12a are mixed may be provided on the teeth 11 as shown in FIG.

Further, the dye 14 and the color developing agent 15 may be separately included in the microcapsules 12a and bonded by the binder 16 (FIG. 2C).

Since the dye 14 may enter the mouth of the human body, it is preferably a food dye.

The surface of the tooth 11 shown in FIG. 1 may be coated with a coloring agent that falls off when the force of repeated brushing by the toothbrush is applied. As such a coloring agent, a dentifrice is preferred.

As the jaw model 10, it is most appropriate to use one's own tooth profile. In addition, even when there are irregularities in the dentition, in the jaw model 10 according to the embodiment of the present invention, it is possible to freely access the dentition from the outside. It is easier to understand what is good.

In addition, such a model for brushing practice is suitable for teaching in a small group, because a plurality of models can be used to teach brushing simultaneously.

Next, another example of the toothbrush practice model according to the present invention will be described. FIG. 4 shows a dentition model 20 as a model for practice brushing according to a second embodiment of the present invention.
