Description

Stretchable or easily stretched oral tooth adhesives {The easily expanding plasters for the oral product}

The present invention relates to a tooth adhesive for use in teeth in the oral cavity. That is, it is mainly produced in the form of adhesives, ie patches, plastases, etc., by containing substances having a whitening effect, but not limited thereto, and containing other functional substances such as caries prevention, bad breath removal, deodorization, and periodontal prevention effects. It is a formulation that can be delivered to the surface of the tooth for a long time to obtain high efficacy

The present invention has the advantage that can be easy even during the whitening procedure by using an adhesive agent that stretches or stretches well without using the mold (rubber dam) of the teeth as compared to the whitening system that is conventionally performed in the dentistry Compared with conventional formulations, it has much higher elasticity, so it can easily penetrate every corner of the drug between the teeth and give better whitening effect.

The prior art is as follows. Conventionally, in order to obtain tooth whitening efficacy, a tooth abrasive and a toothbrush are used, and the polishing component included in the tooth abrasive is achieved through polishing. However, it was difficult for the toothbrush to be insane about the tooth and the part where the interlocking part was recessed.

In addition, the professional teeth whitening program that is visited by a dentist and receives a dental whitening room using a high concentration of whitening agent 3 ~ 4 times a day for 30 minutes to 1 hour and sleeps whitening home using a custom device (rubber dam) in parallel. Is to enforce. The rubber dams are specially fitted to the oral cavity to avoid bleach chemicals coming into contact with the soft tissues of the oral cavity. This rubber dam must be reused for installation, cleaning, insertion and removal of oral teeth, etc., so it must be manufactured sufficiently hard not to be damaged in this process. Thus repeated use of this device causes oral gum damage from the edges.

In addition, there is a self-whitening method, and the corresponding products are a set consisting of a bleaching gel and a mouthpiece (rubber dam). These products are inexpensive, but the size of the device that fits in the mouth of the mouth Designated in batches regardless of tooth shape, problems can arise when compared to patient-specific adjustments, such as for professional use.

And the patent for solving the said problem is already published. As a way to solve the above-mentioned problems, US Pat. No. 58,914,53 describes a strip form in which a support layer is made of a strip material such as fluoroplastic or polyethylene, and in some cases, pockets are applied to apply a peroxide-containing gel. The formulation features a secure and easy way to attach and detach teeth and bend easily without the need for a rubber dam. However, this formulation does not stretch well and does not stick neatly on the teeth, making it uncomfortable to wear and may cause problems in use.

In another patent, JP10017448 proposes a method of obtaining an effect by using ethyl cellulose, cellulose acetate, and the like as a water-insoluble polymer and using ascorbic acid, nurukic acid or derivatives thereof as a whitening ingredient. However, the characteristics of this formulation is also effective to remove the coloring by coffee, green tea, etc., but also increases the well, or does not use a friendly material, it feels somewhat hard, etc. And expensive polymers.

The present invention is characterized by ameliorating the above-mentioned problems with tooth whitening adhesives in the oral cavity.

The following configuration is intended to solve the aforementioned problem. This can be explained by patch or cataplasma formulations. This is shown in the following figure. First, the supporting layer corresponding to the first step is explained. That is, there is a water impermeable support layer that is excellent in elasticity and flexibility, but in some cases, even better than anything else.

And there is a tooth attachment layer corresponding to number 2 in the figure. It is composed of a tooth adhesion layer that is applied on the first support layer and dissolved in water, and easily adheres or adheres to the skin, teeth or gums around the teeth by water or saliva. In some cases, release paper may be used so that the shape of the structure is well preserved.

In particular, in the case of the present invention, excellent supportability and flexibility while using a particularly elongated support layer makes the tooth adhesion layer easily reach not only the exposed surface of the tooth but also the invisible areas between the teeth with only a small pressure. In other words, the support layer is well deformed to help the tooth attachment layer to reach well. In addition, the present invention may be mixed with a tooth whitening agent, or optionally a therapeutic agent for oral diseases in the tooth adhesion layer.

The elasticity and flexibility of the above, but in particular, because the use of a support layer that can not penetrate even in some cases may implement a formulation in which the whitening component is delivered in only one direction. That is, the tooth whitening component can be easily eluted and lost in the tooth attachment layer, but the whitening component does not flow through the support layer. Therefore, polyurethane can be cited as a polymer having excellent elasticity and flexibility and achieving the above object with only a small pressure and having excellent film forming ability without dissolving in water. It is also characterized by little adhesion to the gums of teeth.

In addition, the tooth adhesion layer attached to the teeth or gums by saliva or water in the oral cavity is attached to the surface of the teeth for a long time, so that the whitening component can act, and elutes and disappears over time to brush teeth after a certain time. Can be removed by hand or by hand. For this purpose, the tooth adhesion layer includes various natural gums such as alginate, xanthan gum and cellulose such as hydroxypropyl cellulose. Others include carbopol, poloxamer and polyvinyl. Alcohol, polyvinylpyrrolidone, or mixtures thereof.

In addition, the whitening agent applied to the tooth sticking layer uses an oxygen-based bleaching component such as hydrogen peroxide, urea peroxide, percarbonate, perborate or calcium peroxide, ascorbic acid or nurukic acid and derivatives thereof.

In addition, medicinal substances that can be applied to oral diseases can be added to the tooth adhesion layer, and medicinal substances that can be used for bad breath, deodorant or periodontal disease, and sensitive dental diseases, or fragrances can be added for more convenient use. have.

Tooth adhesive of the present invention is excellent in elasticity and flexibility, and in some cases by using a support layer having a property that stretches well can increase the tooth whitening effect and increase the feeling of use.

Example

Hereinafter, although an Example and a comparative example are shown and this invention is demonstrated concretely, this invention is not limited to the following Example. In addition, the tooth adhesion layer solution was applied onto the support layer film in the following example, preliminarily freeze-dried, and a tooth adhesive was prepared. % Represents weight% of course. Comparative Example 1 The process of preparing the support layer film is vacuum drying and manufacturing based on the following solution. In Comparative Example 2, the tooth adhesion layer corresponds to a gel.

Each of the above Examples and Comparative Examples were prepared to compare the ease of use of Example 2, Comparative Example 1 and Comparative Example 2 for 30 volunteers. Divided into 3 groups of 10 people each, the order of wearing of each product is determined so that the order effect does not appear, and each product is worn twice a day for 3 days (for a total of 9 days). Evaluation was made on a scale. The result was displayed.
