Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a denture, and more particularly, to a denture in which a concave portion is provided in an upper jaw portion of a base to generate an adsorbing force in close contact with an upper palate and improve an anchoring force in an oral cavity.

[0002]

[Prior art]

 Traditionally, dentures have been used by people who have lost their teeth due to aging or oral diseases to chew food. As shown in FIG. 3, this type of denture 1 includes a base 10 and a large number of artificial teeth 11 provided on the bottom surface of the base 10. The base 10 includes an upper jaw 110 that is in close contact with an upper palate (not shown) and a tooth bed 111 that is in close contact with a gum (not shown). The artificial tooth 11 is provided on the bottom surface of the tooth bed 111 so as to be implanted.

[0003] When the denture 1 having the above configuration is mounted on the upper palate in the oral cavity, the dental bed portion 111 comes into close contact with the gum, and the upper jaw portion 110 comes into close contact with the upper palate. Thus, the denture 1 is fixed in the oral cavity by utilizing the frictional force due to the close contact of the tooth base 111 with the gum.

[0004]

[Problems to be solved by the invention]

 However, although the denture 1 has the effect of being fixed in the oral cavity, there is still a problem in practical use. Specifically, the denture 1 is fixed so as not to fall off the base 10 by utilizing the frictional force generated by the close contact of the tooth bed 111 and the close contact of the upper jaw 110, but the dentition of the user over time is reduced. As the atrophy gradually grows, a gap is formed between the toothbed 111 and the gum, and the toothbed 111 cannot be firmly adhered to the gum. As a result, there is a problem that the fixation power is lost, the patient falls off when sneezing or eating, and the appearance is not good, and it is considerably inconvenient.

In order to solve this problem, professionals have developed dentures having excellent stability. For example, a magnetic attraction type denture shown in FIG. 4 is provided. In the denture 2, a magnetic block 21 is embedded in a base 20, and a similar magnetic block 22 is embedded in a position facing the gum 3, and the magnetic blocks 21 and 22 are attracted to each other by magnetic force. Improves stability when mounted.

However, in order to use the magnetic attraction type denture 2, the magnetic block 22 must first be buried in the gum 3, which gives a rather unpleasant feeling. However, it takes a considerable amount of time to manufacture the denture 2 and the magnetic lines of force generated between the magnetic blocks 21 and 22 are close to the brain, which may have an undesirable effect.

[0007] A magnetic repulsion denture is provided in Taiwan Patent Publication No. 325,674. As shown in FIG. 5, the magnetic repulsion type denture has magnetic blocks 401 and 411 embedded in an upper denture 400 and a lower denture 410 that face each other of an upper denture 40 and a lower denture 41. The magnetic blocks 401 and 411 are provided with mutually repelling magnetic forces (the same magnetic poles), so that the magnetic blocks 401 and 411 exert an action of pressing the upper and lower gums 42 and 43 from each other. ing. This prevents the magnetic blocks from being embedded in the upper and lower gums 42 and 43, thereby preventing the user from feeling uncomfortable.

However, this magnetic repulsion type denture does not require the magnetic blocks to be embedded in the gums 42 and 43, but the cost of making the denture is still high. Moreover, the effect of the magnetic blocks 401 and 411 on the human brain has not been solved.

The present invention has been made in view of the above-mentioned problems of the conventional denture, and has a concave portion in an upper jaw portion of a base to generate an adsorbing force to adhere to the upper palate so as to adhere to the upper palate, thereby making the intraoral cavity. An object of the present invention is to provide a denture that can improve the fixing power of a tooth.

[0010]

Means for Solving the Problems In order to solve the above problems, a denture according to the present invention includes an upper jaw portion that closely adheres to the upper palate in the oral cavity at a base and a tooth bed portion that is continuous with the upper jaw portion and closely adheres to the gums. And a denture in which a large number of artificial teeth are implanted on the bottom surface of the tooth bed portion, wherein a concave portion is provided on a surface of the upper jaw which is in close contact with the upper palate.

[0011] In the denture, it is preferable that a concave portion is provided on a surface of the tooth bed that is in close contact with the gum.

According to such a denture, when the denture is installed in the oral cavity, the tooth bed is in close contact with the gum so as to fit into the gum, the upper jaw is in close contact with the upper palate integrally with the recessed portion, and Saliva infiltrates into the concave portion of the upper jaw and the periphery of the concave portion of the tooth bed. As a result, since the upper palate and the gums have flexibility, the recesses and the recesses adhere to the upper palate and the gums, respectively, and act like a suction cup to generate an adsorbing force, thereby firmly strengthening the base in the oral cavity. It can be fixed inside.

[0013]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. As shown in FIGS. 1 and 2, the denture 5 of the present invention includes a base 50 and a number of artificial teeth 51 provided so as to be fitted into the base 50.

The base 50 includes an upper jaw 52 that is in close contact with the upper palate 6, and a tooth bed 53 that is in close contact with the gum 7. The upper jaw 52 is integrally formed so as to be continuous with the inner peripheral edge of the tooth bed 53. The artificial teeth 51 are provided on the bottom surface of the tooth bed 53 so as to be implanted one by one. In the present embodiment, a concave portion 520 is provided on a surface of the upper jaw 52 that is in close contact with the upper palate 6. In addition, a concave portion 530 is provided on a surface of the tooth bed portion 53 that is in close contact with the gum 7.

When the denture 5 having the above configuration is mounted in the oral cavity 8, as shown in FIG. 2, the tooth bed 53 comes into close contact with the gum 7 of the human body. In addition, the upper jaw 52 comes into close contact with the upper palate 6 integrally with the recess 520. Then, when the base 50 is fitted by saliva generated in the oral cavity 8 of the human body, the saliva permeates and adheres to the periphery of the concave portion 520 of the upper jaw 52 and the concave portion 530 of the tooth bed 53.

Then, since the upper palate 6 and the gum 7 of the human body are flexible, the concave portion 520 and the concave portion 530 generate, for example, a suction force such as a suction function of a suction cup, and the upper palate 6 and the gum 7, respectively. 7, the base 50 can be firmly fixed in the oral cavity 8. That is, the fixing property can be surely improved.

Therefore, for example, even if the tooth bed 53 and the gum 7 of the user gradually atrophy and the state of close contact is gradually reduced, the base 50 is absorbed by the concave portion 520 and the concave portion 530. Can be surely fixed, and the problem of easily falling off over time as in the conventional case can be suppressed.

The present invention is not limited to the configuration of the above-described embodiment. For example, it is not necessary to provide the concave portion 530 in the tooth bed portion 53, and the concave portion 520 is provided only in the upper jaw portion 52. Various changes are possible.

[0019]

[Effect of the invention]

 As is clear from the above description, the denture of the present invention has a concave portion in the upper jaw that is in close contact with the upper palate of the human body, and a denture in the tooth bed portion that is in close contact with the gums of the human body. When attached to the oral cavity and saliva seeps into and adheres to the periphery of the concave portion and the concave portion, a strong suction force can be generated in the upper jaw and the tooth bed. Therefore, the base can be firmly fixed in the oral cavity.

In addition, unlike a magnetic attraction type denture and a magnetic repulsion type denture, a magnetic block is unnecessary, so that the cost can be significantly reduced in comparison with these, and the effect on the human brain is also reduced. Not at all. Furthermore, unlike a magnetic attraction denture, there is no need to bury a magnetic block in the gums of the human body, so that the user does not feel uncomfortable.
