Description

The present invention relates to a gum-like, powder-like or sheet-like denture stabilizer having a color tone similar to that of a denture base and having excellent aesthetics when used in the oral cavity. About.

[Problems to be solved by conventional technology and invention]

When a removable denture is loosened, the denture stabilizer is used for the purpose of fixing the denture and improving occlusion, and is generally classified into a close contact type and an adhesive type depending on the method of fixing the denture. In addition, dosage forms include gum, paste,
It can be classified into powder, sheet and the like.

These denture stabilizers usually contain a coloring agent for the purpose of covering the color of the base or improving the aesthetics when used in the oral cavity. It is desired that the close contact type denture stabilizer which can be used for a long period of time is close to the color tone of the denture base and the oral mucosa.

Conventionally, as a coloring agent for a denture stabilizer used for such a purpose, a water-soluble dye has been used alone or in various combinations.

However, conventional denture stabilizers using water-soluble dyes are difficult to resemble the color tone of the denture base, tend to have an unnatural color tone, and are prone to denture stabilization when faded or stored for a long period of time. It is easy for liquid separation to occur in the agent, and when such liquid separation occurs, the separated liquid is colored,
Even if the amount of liquid separation is small, there is a problem that the appearance quality is significantly impaired.

The present invention has been made in view of the above circumstances, is similar to the color tone of the denture base, is excellent in aesthetics, and hardly causes liquid separation even when stored for a long time, and has separated even if liquid separation occurs. An object of the present invention is to provide a gum, powder, or sheet denture stabilizer that does not cause coloring of the liquid.

[Means and Actions for Solving the Problems]

The present inventors have conducted various studies to achieve the above object, and as a result, have found that a water-insoluble red pigment iron sesquioxide (red petal) is used as a coloring agent for coloring a gum, powder or sheet denture stabilizer. By using it, the denture stabilizer can be easily brought close to the color tone of the denture base and can be made similar,
Compared to the case of using a water-soluble dye, it is difficult to cause liquid separation in the denture stabilizer, and even if liquid separation occurs, the separation liquid is not colored, and it is found that there is little loss of quality. I've reached the point.

Accordingly, the present invention provides a gum, powder, or sheet denture stabilizer containing a water-insoluble red pigment, iron sesquioxide, as a coloring agent.

 Hereinafter, the present invention will be described in more detail.

The denture stabilizer according to the present invention may be any of a contact type and an adhesive type, and may be any of a gum type, a powder type, and a sheet type, using known components according to the type. Can be prepared.

For example, when obtaining a denture stabilizer with a close contact type mainly composed of vinyl acetate resin, as described in JP-B-61-36802, a vinyl acetate resin, and if necessary, non-toxic oils and waxes, Active ingredients such as oil-soluble emulsifiers, water-insoluble powders, enzymes and the like can be used, and these can be formed into a gum by using water and a lower alcohol as a solvent.

In addition, in the case of other types of denture stabilizers, they can be similarly produced using appropriate components.

Thus, the present invention incorporates a water-insoluble red pigment, iron sesquioxide (petal oxide), into the denture stabilizer as a colorant. In this case, in the present invention, other water-insoluble pigments may be blended for adjusting the color tone.

As the iron sesquioxide, iron sesquioxide obtained by calcining anhydrous iron sulfate obtained by dehydrating ferrous sulfate at 650 to 1000 ° C., and then pulverizing and drying it, is preferably used.

The compounding amount of the above iron sesquioxide can be variously selected, but is 0.001 to 1% (% by weight) of the whole composition, particularly 0.01 to 1%.
Preferably, it is 0.5%.

〔The invention's effect〕

ADVANTAGE OF THE INVENTION According to the denture stabilizing agent of this invention, it is similar to the color tone of a denture base, and liquid separation does not easily occur, and even if liquid separation occurs, the separation liquid does not have coloring.

 Next, the effects of the present invention will be specifically described with reference to examples.

[Experimental Example 1] A denture stabilizer having the following composition using the coloring agents shown in Table 1 was prepared, its color tone was evaluated, and ACRON No.3 manufactured by Jiji Dental Industry Co., Ltd. was used as a denture base resin. And the similarity with the denture base color was compared. The results are shown in Table 1.

The amount Purified water balance Total 100% shown in Table 1 denture fixative composition vinyl acetate resin 50% stearic acid monoglyceride 1 beeswax 3 soft calcium carbonate 7 Ethanol 20 colorant [Experimental Example 2] For the denture stabilizers No. 6 and No. 8 used in Experimental Example 1, a paired comparative questionnaire survey was conducted on 24 denture users to determine which sample was closer to the color of the denture base. The results are shown in Table 2.

From the results shown in Tables 1 and 2, it is recognized that a denture stabilizer having a color tone close to the color of the denture base can be obtained by using iron sesquioxide.

[Experimental Example 3] When the denture stabilizers Nos. 6 to 8 used in Experimental Example 1 were stored at 50 ° C for one month, a cycle test at -5 ° C to 10 ° C (1 cycle: 2 days) was performed for 1 month. The inter-day stability when performed for months was evaluated for the items shown in Table 3. The results are shown in Table 3.

From the results shown in Table 3, it was confirmed that liquid separation could be reduced as much as possible by using the water-insoluble red pigment, and the separated liquid was colorless and transparent without coloring.

Hereinafter, although an example is shown, the present invention is not limited to the following example.
