Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to dentures, in particular, dentures designed to prevent accidental removal.

[0002]

[Prior art]

 Teeth can loosen or fall out for various reasons associated with periodontal disease and aging. Older people in particular often lose teeth compared to younger ones, but this also occurs in traffic accidents. In some cases, one or two teeth may be lost, but most or all of the teeth may be lost. In such a case, full dentures or partial dentures are generally used, but the upper denture has a problem that it often comes off.

[0003] When a tooth is missing, it is necessary to make a denture or a denture by a dentist in order to compensate for the missing part of the tooth and enable mastication. The dentist will make a denture to prosthesis where the tooth has fallen, but if there are few or no teeth left, a denture that fits the curved surface of the gums or jaw of the remaining teeth Create a set of artificial teeth, or dentures, to give the appearance and help the patient chew food.

[0004] The purpose of artificial dentures used today is to provide a pair of dentures (consisting of denture base and denture) that look good. The upper and lower dentures adhere to the upper and lower jaws and gums due to the adhesive force of saliva in the oral cavity, but this adhesion is not always sufficient, and in many users' experience, when chewing food, When the mouth was wide open or coughing, the upper denture often came off unexpectedly.

In order to solve such a problem, a hole is drilled in a root remaining in the upper and lower gums, and a magnetic root body whose surface is covered with a protective layer is implanted therein. A technique has been proposed in which a magnetic denture, in which a magnet that attracts the body is embedded in a denture denture, is attached, and the magnetic attraction between the magnet and the magnetic root body increases the attraction of the denture to the gums.

[0006] In addition, the gums that have lost teeth are incised to expose the jaw bone, drilled therethrough, implanted with a corrosion-resistant metal anchor through an artificial aggregate, fixed, and an artificial denture is taken therefrom. Attached so-called implants are also spreading.

[0007] However, these methods require a considerably high level of surgery, such as perforating the roots and jawbone, and thus involve a certain amount of risk, are expensive, and cannot be performed on the elderly or the sick. There is such a problem.

[0008]

[Problems to be solved by the invention]

 The present invention has been made to solve the above-mentioned problem, and has as its object the provision of a suction pad, which can be securely attached to a tooth or a jawbone without perforating the tooth and the gum. An object of the present invention is to provide dentures that are strongly adhered to the teeth.

[0009] Still another object of the present invention is to provide a denture which can be suitably applied to a patient having no teeth, a sick person, and the like.

[0010]

[Means for Solving the Problems]

 The above object of the present invention is achieved by a denture in which an upper or lower denture is provided with a suction disk at a portion thereof not facing the gum. Since the suction cup is firmly attached to the gums, the denture does not come off even when the food is chewed or when the mouth is widely opened.

[0011]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. 1 is an explanatory view showing an embodiment of an upper denture according to the present invention, FIG. 2 is an enlarged sectional view showing details of a suction disk provided on the denture, and FIG. 3 is a cross-sectional view showing a state where the denture is mounted. FIG. 4 is an explanatory view showing an embodiment of the lower denture.

In FIG. 1, reference numeral 3 denotes an upper denture, 11 denotes an upper jaw, and 12 denotes a gum. Upper dentures 3 correspond to both ends of a groove portion 32 in contact with the gum 12 of the denture base 31. Adsorbers 2 and 20 are provided in the vicinity.

As shown in FIG. 2, each of the suction cups 2 and 20 comprises a substantially frusto-conical suction cup 21 and a fixture 22. The suction cup 21 is made of a flexible synthetic resin and has a center of a lower flat plate portion. Has a mounting hole 24 and a circular opening 23 above. The attachment 22 is provided with a thick and short center shaft 25, a disk portion 26 integrally provided with the center shaft 25 for holding the suction cup 21 at an upper end thereof, and a lower end integrally formed with the center shaft 25. It has a turn-up portion 28 at the peripheral edge, and comprises a dish-shaped anchor 27 embedded in a groove portion 32 that contacts the gum 12 of the denture base 31 together with most of the central shaft 25.

The upper denture 3 is mounted on the upper gum 12 as shown in FIG. 4. At this time, the suction cup 21 strongly adheres to the surface of the gum 12 and Is fixed.

In FIG. 4, 4 is a lower denture, 51 is a lower jaw, and 52 is a gum. The lower denture 4 is near both ends of a groove portion 42 in contact with the gum 52 of the denture base 41. Is provided with suction disks 2 and 20. The configuration of the suction cups 2 and 20 shown in FIG. 4 is the same as that shown in FIG. 2 described above, so that the lower denture 4 is placed in the groove portion 42 of the denture base 41 that contacts the gum 52. Adsorbs strongly.

These dentures 3 and 4 are formed so that their denture bases conform to the shapes of the outer surfaces of the gums 12 and 52, respectively, similarly to known dentures. Because of the interposition of saliva, these dentures 3 and 4 are attached to the corresponding gums 12 and 52, respectively, and since the suction pads 2 and 20 are strongly attached to the gums 12 and 52, When an external force is applied to remove this, the saliva acts to create a vacuum at the joint surface, so that the denture will come off even if you open your mouth widely, chew sticky food, or cough. There is no such thing.

The configuration of the present invention is not limited to the above-described embodiment. For example, the configuration of the suction cup, in particular, the shape of the suction cup and the fitting can be freely changed. The attachment may be screw-type, rivet-type, anchor-type, etc., and may be molded integrally with the suction cup. Also, the mounting position and quantity of the denture base, etc. The present invention includes all of the modified embodiments.
