[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a denture having a preformed denture base, and more particularly to a denture for the upper jaw.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional denture has a denture base 2 made of a resin or a metal, a denture 2 and a resin 3 made of resin.
It is formed by fixing through. In particular, in the case of a denture for the upper jaw, in order to make it close to the palate,
Molding is performed according to the curvature of the palate.

In the conventional denture thus produced, even if the denture base is precisely produced according to the curvature of the palate to improve the adhesion, it cannot be said that the denture has sufficient adhesion. It is a thing. That is, there was a gap between the palate and the denture base, food was caught between them, it was difficult to talk, and it was easy to detach. not to mention,
It was difficult to chew hard food well, because it easily detached when eating hard food. Also, not only does something get caught between the palate and denture base, causing pain,
It often caused inflammation.

[Problems to be solved by the device]

The object of the present invention is to solve the problems in the conventional dentures such as food being caught between the dentures and being easily detached from the dentures, and to enhance the adhesion between the palate and the denture base.

[Means for Solving the Problems]

According to the present invention, in order to enhance the adhesion between the palate and the denture base, the peripheral edge of the denture base on the side where the denture is attached and the peripheral edge on the opposite side are bent toward the palate. As a result, the outside air and the like do not enter between the palate and the denture base, and the adhesion is significantly improved.

【Example】

FIG. 1 is a sectional view showing an embodiment of a denture according to the present invention, in which the denture is mounted in the mouth.
This denture is formed by an ordinary manufacturing method in which a denture 2 is fixed to a denture base 1 made of resin or metal via a resin 3. In particular, in the case of a denture for the upper jaw, in order to produce the denture in close contact with the palate, shaping is performed according to the curvature of the palate. The part 1a is bent toward the palate. When the denture formed in this manner is attached, the peripheral edge portion 1a is bent toward the palate, so that a slight sealed space is formed between the palate and the denture base, and thus negative pressure is generated, The adhesion between the palate and the denture base is enhanced.
Therefore, even if you bite a hard object, it will not come off even if you bite it, and you will not come off even if you talk, so you can pronounce clearly and the wearing feeling is very good.

FIG. 2 shows the essential parts of a second embodiment according to the present invention. This denture is the same as the previous embodiment in that the peripheral edge 1a of the denture base on the side opposite to the side to which the denture is attached is bent toward the palate, but this peripheral edge 1
The end portion 1aa of a is made substantially parallel to the surface of the denture base before bending. As a result, it was found that the adhesion was further enhanced and the wearing feeling was enhanced as compared with the previous examples.

FIG. 3 shows the essential parts of a third embodiment according to the present invention. This denture is the same as the first or second embodiment in that the peripheral edge 1a of the denture base on the side opposite to the side to which the denture is attached is bent toward the palate, but the denture base is the same. Of the denture base and the end portion 1aa of the peripheral edge portion 1a opposite to the side to which the denture is attached.
Is formed of a soft resin. This further enhances the wearing feeling.

[0009]

As described above, according to the present invention, by bending the peripheral edge portion of the denture base on the side opposite to the side where the denture is attached toward the palate, a closed space can be created between the palate and the denture base, Because the negative pressure is generated, the outside air does not enter,
It has become possible to significantly improve the adhesion.

In the above description, a resin or metal is used as the denture base, but it goes without saying that it is not limited to this. Also,
The shape of the peripheral edge portion of the denture base on the side opposite to the side on which the denture is attached is not limited to that described above, and various modes are possible.

Claims (3)

[Scope of utility model registration request] 1. A denture, characterized in that a rim of the denture base on the side to which the denture is attached and a rim on the opposite side are bent toward the palate. 2. The denture base has a peripheral edge portion on the side where the denture is attached and a peripheral edge portion on the opposite side to the palate, and the end portion of the peripheral edge portion is substantially the same as the surface of the denture base before bending. The denture according to claim 1, wherein the denture is parallel. 3. The denture base is formed of a resin, and the rim of the denture base on the side where the denture is attached and the end of the rim opposite to the rim are formed of a soft resin. 1 denture.
