The present invention relates to a shade clasp denture, and more particularly, to a shade clasp that allows a user to speak confidently or smile with an open mouth by forming a ring fixed to a user's tooth in the same color as the corresponding tooth. It's about Denture.

In general, dentures used by users who have lost some of their teeth are manufactured by opening a mold of the user's teeth and gums, forming a main body by applying a synthetic resin to the mold, and fixing a denture of an appropriate shape to the main body.

At this time, the main body is composed of a synthetic resin material with high strength.

Therefore, when the main body is fixed to the user's gums, the denture is placed in a predetermined position and functions as a missing tooth.

On the other hand, since the main body of such a denture is made of a synthetic resin material with high strength, the main body strongly presses the user's gums during use, causing pain in the gums, and it is difficult for the main body to be well fixed to the gums.

Therefore, the present applicant has developed and registered a patent for a flexible denture in which the main body is made of a polyester-based synthetic resin having appropriate elasticity in order to solve this problem. (Registration Patent No. 10-1636952)

On the other hand, such a flexible denture is mainly used by patients who have lost molars while remaining front teeth, and has the advantage of being easy to use and significantly reducing pain felt by the user.

However, since the main body of such a flexible denture is made of a flexible synthetic resin material, the pain felt by the user in a general situation is remarkably reduced. There is a problem in that the main body moves and stimulates the user's gums, thereby causing pain.

In particular, since the body of such a flexible denture is configured in a constant pink color, it is easily noticeable and has problems that are not aesthetically pleasing.

Therefore, there is a need for a new method capable of solving these problems.

On the other hand, in the case of a user using such a flexible denture, there are many cases where only the molars on both sides are lost while the front teeth remain.

Therefore, the present applicant has developed and registered a patent for a transparent flexible denture to solve these problems. (Registration Patent No. 10-1987251)

When this transparent flexible denture is worn by the user, the fixing member is fixed to the rear surface of the user's front teeth, supporting the main body, especially the left and right fixing parts, so that they do not move, thereby preventing the user from feeling pain during chewing activities. There are advantages.

However, since the hook part of such a transparent flexible denture is transparent, when the user speaks or smiles with his mouth open, it is exposed to the other party and there is a problem that it is discovered that he is wearing the denture.

Therefore, the user has to pay attention to the fact that he or she is wearing the denture when talking or laughing, and loses confidence in daily life.

Therefore, when the shade clasp denture according to an embodiment of the present invention is worn, the hook part 15 is caught on the user's tooth 1a and fixed so that the front ends of the left and right fixing parts 11 and 12 do not move, so that the chewing activity In addition, it is possible to more effectively prevent the left and right fixing parts 11 and 12 from flowing, and the ring part 15 is not conspicuous, so aesthetics are further improved.

Furthermore, the ring part 15 may further include a core material 151 embedded in the body part 10 .

The core material 151 is formed in a rod shape having a certain length and thickness, and is integrally formed on one side of the ring part 15.

Since the core material 151 is embedded and fixed inside the body portion 10, the ring portion 15 is stably fixed on the body portion 10 so as to continuously maintain a state caught on the user's tooth 1a. do.

The ring portion 15 may be formed in the same color as the color of the user's teeth 1a.

For example, the ring part 15 applies resin powder 5 corresponding to the color of the user's tooth 1a to the surface of the flexible and transparent resin 4, and heats it to a temperature of 250 ° C to 350 ° C. After melting, it can be molded into a ring shape by injection.

Specifically, the resin 4 is a dental resin formed in a color having a predetermined transparency, and may be formed in a granular form.

The resin 4 may be applied in several pieces to form the ring portion 15 and the core material 151 .

That is, since the lengths and sizes of the ring part 15 and the core material 151 are different for each user, the number of applications of the resin 4 may be different for each user.

The resin powder 5 is formed in the same color as that of the tooth 1a.

The resin powder 5 is evenly applied to the entire surface of the resin 4 .

After the resin powder 5 is evenly buried on the surface of the resins 4 constituting the granular shape, the shape corresponding to the ring part 15 and the core material 151 is formed through the resin supply module 50 shown in FIG. The resins 4 may be injected into the molding space 60a of the molding machine having the molding space 60a.

At this time, the resin supply module 50 may include an accommodation space in which the resins 4 are accommodated and a piston 51 supplying the resin 4 located in the accommodation space to the molding space 60a of the molding mold 60. there is.

In addition, the resin 4 located in the receiving space and the resin powder 5 applied to the resin 4 are heated to a temperature of 250 ° C. to 350 ° C. through a separate heating device from the outside of the resin supply module 50 and melted. state, and the piston 51 supplies the molten resin 4 to the molding space 60a.

The forming space 60a is formed in a shape corresponding to the ring portion 15 and the core material 151 of FIG. can do.

At this time, the color of the resin powder 5 is adjusted in density and brightness according to the color of the user's teeth 1a.

When the ring part 15 is fixed to the user's tooth 1a, the same color as the tooth 1a is used so that the ring part 15 can be seen as the tooth 1a to the other party when talking or smiling with the mouth open.

Therefore, it is possible for the user to have confidence in daily life, such as allowing the user to comfortably talk or open one's mouth to smile, and to be more active in social life.

As another example, porcelain powder may be substituted for the resin powder 5 described above.

Since porcelain is generally used as a material for making artificial front teeth (1) or ceramics in the dental industry, further detailed description thereof will be omitted.

Even when the ring part 15 and the core material 151 are formed with porcelain powder instead of the resin powder 5, the ring part 15 can be shown in the same color as the tooth 1a.

Additionally, a plurality of fixing parts 40a and 40b may be formed on the outer surface of the core material 151 at regular intervals.

The fixing parts 40a and 40b may be formed of a flexible material.

For example, the fixing parts 40a and 40b may be made of synthetic resin or the same material as the ring part 15 .

The fixing parts 40a and 40b may come into contact with the mold 3 together with the core material 151 and be embedded in the body part 10 .

For example, as shown in FIG. 17 , the fixing unit 40a may be formed in a coil shape.

When polyester or polyamide resin is applied to the gum 2 of the mold 3, which will be described later, the inner space 41a and gaps 42a formed in the coil of the fixing unit 40a are filled with polyester or polyamide resin. Since the amide resin naturally permeates and hardens, the coil-shaped fixing part 40a resists even if the ring exposed to the outside is pulled, so that the core material 151 remains stably embedded in the body part 10, , After all, it is possible to ensure that the ring part 15 is not easily separated from the main body part 10 and maintains a stable fixed state.

As another example, the fixing unit 40b may be formed in a simple bar or pin shape.

Accordingly, the fixing unit is disposed on the circumferential surface of the core material 151 like a branch of a tree.

In addition, a plurality of through holes 41b may be formed at regular intervals in the fixing part 40b.

When polyester or polyamide resin is applied to the gum 2 part of the mold 3, the polyester or polyamide resin naturally permeates into the through holes 41b and hardens, so that the body part 10 and the fixing part 40b ) can be integrally formed.

Even in this case, even if the ring part 15 exposed to the outside is pulled, the fixing part 40b resists, so that the core material 151 remains stably embedded in the body part 10, and eventually the ring part (15) is not easily separated from the body portion 10 and can be maintained in a stable fixed state.
