(Embodiment 1)
A denture base and denture according to Embodiment 1 of the present invention will be described with reference to the drawings.
The denture 10 shown in FIG. 1 can be made into a shape that matches the wearer's oral cavity in a short period of time. The denture 10 is a complete denture worn by a wearer whose lower jaw is an edentulous jaw.
The denture 10 includes a denture base 20 and an artificial tooth 30.

The denture base 20 includes a mounting portion 21 and a support portion 22.
The mounting portion 21 is made of an uncured resin at normal temperature. The cross-sectional shape of the mounting portion 21 is formed in a curved shape in an uncured state. The mounting portion 21 can be made of a curable resin, but can be formed of, for example, a photocurable resin. As the photocurable resin, polyfunctional methacrylate can be used.
Moreover, the mounting part 21 can be made of, for example, a thermosetting resin. As the thermosetting resin, polymethyl methacrylate resin (PMMA) can be used.
Here, normal temperature can be a temperature range of 5 to 35 ° C. (JIS Z 8703).

  Furthermore, the mounting portion 21 can be formed of, for example, a thermoplastic resin that becomes softened at 40 ° C. or higher. Polyethylene terephthalate (PET) can be used as the thermoplastic resin. It is desirable that the thermoplastic resin used as the mounting portion 21 has a softening start temperature of 100 ° C. because the thermoplastic resin can be softened with hot water. Therefore, it is desirable that the thermoplastic resin forming the mounting portion 21 has a temperature at which softening starts in the range of 40 ° C. or higher and 100 ° C. or lower.

The support part 22 supports the artificial tooth 30 by embedding a tooth neck part or a root part of the artificial tooth 30. The skirt portion of the support portion 22 is covered with the mounting portion 21. The support portion 22 is formed of a cured resin.
The artificial teeth 30 are arranged along the arched denture base 20. As the artificial tooth 30, a conventional artificial tooth can be used. For example, the artificial tooth 30 can be a resin tooth, a porcelain tooth, a metal simple substance, or a metal tooth combined with a resin.

  This denture 10 is stored and sold in a light-shielding bag when the mounting portion 21 is formed of a photocurable resin. Further, the denture 10 can be standardized in size such as the depth of the arch shape of the denture base 20 and / or the groove shape of the mounting portion 21. For example, the size of the denture 10 may be prepared as a stepped size according to the size of the wearer's chin ridge, such as SS, S, M, L, XL, No. 1 to No. 10, etc. it can.

  A method of manufacturing the denture 10 according to Embodiment 1 of the present invention configured as described above will be described with reference to the drawings. In the following description, it is assumed that the mounting portion 21 is formed of a photocurable resin.

First, the practitioner selects the denture 10 stored in the light-shielding bag according to the size of the wearer's chin, and tears the bag to take out the denture 10. Then, as shown in FIG. 2A, the practitioner inserts the denture 10 into the wearer's oral cavity and covers the ridge R with the groove of the denture base 20.
Since the mounting portion 21 is formed in a curved shape opened from the chin ridge R, it is easy to be mounted on the ridge ridge R, and is stable when mounted on the ridge ridge R to form the uncured mounting portion 21. A mounting part can be shape | molded in a state.

Next, as shown in FIG. 2 (B), the practitioner presses the outer surface of the attachment part 21 such as the cheek side, the tongue side, and the lip side with a refining spatula or the like, and forms the attachment part 21 in the shape of the chin ridge R. Is molded. Since the artificial tooth 30 is supported by the support portion 22 in a hardened state, the mounting portion 21 can be molded in a state where the artificial tooth 30 is stabilized.
When the jaw ridge R has an undercut, for example, the denture 10 is moved in the insertion / removal direction so that the groove edge portion of the mounting portion 21 (the lower end of the mounting portion 21 in the case of the lower jaw) does not adhere to the ridge R. Mold while letting.

  At this time, when the practitioner is a dentist and the wearer is treating at the dental clinic, the dental equipment is sufficiently prepared so that the artificial teeth 30 can be engaged according to the meshing with the healthy teeth of the upper jaw. The surface may be ground.

When the forming of the mounting portion 21 is completed, illumination is inserted into the wearer's oral cavity, and the mounting portion 21 is irradiated with light. For example, when the wearing part 21 is formed of an ultraviolet curable resin, as shown in FIG. 3, an ultraviolet illuminator L such as a black light is inserted into the mouth of the wearer P to attach the wearing part 21 (FIG. 3) (not shown). FIG. 3 shows a state where the mounting portion 21 near the molar teeth is cured by the ultraviolet illuminator L.
Since the mounting portion 21 is cured by this irradiation, the denture 10 can be formed in a shape that fits the jaw ridge R.

  Since the mounting portion 21 is made of a photo-curable resin, the practitioner simply inserts the ultraviolet illuminator L into the oral cavity and irradiates light while the wearer P is wearing the denture 10 and is in an uncured state. The mounting portion 21 can be cured.

  Since the mounting portion 21 can be easily cured without causing the wearer P to experience pain or severe pain when the mounting portion 21 is cured, the burden on the wearer can be reduced.

Thus, since the mounting part 21 of the denture base 20 is formed of uncured resin, the denture base 10 is mounted on the jaw ridge R according to the shape of the wearer's jaw ridge. It can shape | mold and can be made into a hardening state in the state which matched the shape of the wearer's jaw ridge with the mounting part 21 after that. Therefore, the denture 10 can obtain the wearer's satisfaction by being able to produce a denture base that fits the wearer's ridge in a short period of time.
Moreover, since the denture 10 can be produced easily, the denture 10 can be produced even if the practitioner is not a dentist. Therefore, the denture 10 is produced by an emergency treatment at a dental clinic when a wearer has damaged a denture, or by an emergency treatment at an undeveloped place where the dental clinic is not nearby. be able to.

  In the first embodiment, with the wearer P wearing the denture 10, the practitioner inserts the ultraviolet illuminator L into the wearer's mouth and irradiates light to cure the wearing part 21. However, after the mounting part 21 is formed into the shape of the wearer's chin, the denture 10 may be taken out of the wearer's oral cavity and the mounting part 21 may be cured externally.

  When the mounting portion 21 is formed of a thermosetting resin, when the mounting portion 21 is completely formed, the practitioner takes out the denture 10 from the wearer's oral cavity, applies hot air, puts it into a furnace, or puts liquid (for example, The mounting part 21 can be hardened by being immersed in hot water.

Next, a case where the mounting portion 21 is formed of a thermoplastic resin that becomes softened at 40 ° C. or higher will be described.
First, the mounting portion 21 is heated to 40 ° C. or higher to be in a softened state. This heating applies hot air to the mounting part 21 or immerses the denture 10 in the liquid.
The hot air can be heated air from a dryer. In the case of a dryer, since the temperature is set to be 140 ° C. or less at 3 cm from the blowout port, hot air that is 40 ° C. or more can be easily obtained. Further, if the mounting portion 21 is made of a thermoplastic resin that softens at 100 ° C., the dryer can be softened.

In addition, when the denture 10 is immersed in a liquid, the water in the pot or kettle is heated with a stove or the electric pot is used to heat the water, so that the denture 10 is immersed therein. To do.
Thus, since the mounting part 21 is formed of a thermoplastic resin having a temperature of 40 ° C. or higher, the mounting part 21 can be in a softened state because it is familiar.

When the mounting portion 21 is in a softened state, the denture 10 is mounted on the chin ridge of the wearer in the same manner as the mounting portion 21 formed of the photocurable resin described with reference to FIG. It shape | molds in the shape of a bank (refer FIG. 2 (A) and the same figure (B)).
And the denture 10 is removed from a wearer, a cold wind is applied, it is immersed in water, or it is left to stand at normal temperature, the temperature of the mounting part 21 is reduced, and the mounting part 21 is hardened.
By doing so, it can be set as a hardening state in the state which matched the mounting part 21 with the shape of the wearer's chin. Therefore, the denture 10 can obtain the wearer's satisfaction by being able to produce a denture base that fits the wearer's ridge in a short period of time.

  The temperature at which the mounting portion 21 is softened is 40 ° C. or higher, and more preferably 60 ° C. or higher. By setting the mounting portion 21 to 60 ° C. or higher, it can be softened at a temperature of about the level of hot water before boiling without being softened even at a high body temperature.

At this time, when the mounting portion 21 is made of a thermoplastic resin that is softened at 40 ° C., the temperature at which the mounting portion 21 is cooled and hardened can be included in a range of 30 to less than 40 degrees. Moreover, when the mounting part 21 is made of a thermoplastic resin that softens at 60 ° C., the temperature for cooling and curing can be included in the range of less than 30 to 60 degrees. Furthermore, when the mounting part 21 is made of a thermoplastic resin that softens at 100 ° C., the temperature for cooling and curing can be included in the range of 30 to less than 100 degrees.
Thus, since the hardening start temperature which cools and hardens from the softening start temperature is low, when the mounting part 21 begins to soften, the denture 10 is mounted on the wearer's jaw ridge and molded into the shape of the chin ridge. Even when the temperature of the wearing portion 21 is lowered due to the body temperature of the wearer, it is possible to prevent the wearer from immediately hardening. At this time, it is desirable that the difference between the temperature at which the mounting portion 21 softens and the temperature at which the mounting portion 21 begins to harden is 10 ° C. or more because the mounting portion 21 can be more easily molded.

(Embodiment 2)
An artificial tooth and a denture according to Embodiment 2 of the present invention will be described with reference to the drawings.
The denture 11 shown in FIG. 4 can make the artificial tooth into a shape that matches the tooth of the wearer. The denture 11 is a complete denture worn by a wearer whose lower jaw is an edentulous jaw.
The denture 11 includes a denture base 20x and an artificial tooth 31 that is implanted in the denture base 20x and forms a U-shaped dentition.
Unlike the denture base 20 according to Embodiment 1, the denture base 20x is a hard denture base. The denture base 20x can be prepared in stages such as SS, S, M, L, XL, No. 1 to No. 10, etc., depending on the size of the wearer's chin.

The artificial tooth 31 is planted on the denture base 20x. The artificial tooth 31 is made of an uncured resin at room temperature. As the uncured resin at room temperature, the same resin as the mounting portion 21 of the denture base 20 according to Embodiment 1 can be used. For example, the artificial tooth 31 can be a photocurable resin or a thermosetting resin.
Furthermore, the artificial tooth 31 can be formed of a thermoplastic resin that becomes softened at 40 ° C. or higher.

  The manufacturing method of the denture 11 which concerns on Embodiment 2 of this invention comprised as mentioned above can be performed in the following processes. In the following description, it is assumed that the artificial tooth 31 is formed of a photocurable resin.

  First, the practitioner selects the denture 11 having a size of the denture base 20x corresponding to the size of the wearer's chin, and tears the light-shielding bag in which the denture 11 is stored, and takes out the denture 11. Then, the practitioner inserts the denture 11 into the wearer's mouth and covers the ridge of the denture base 20x with the groove.

  Next, the practitioner causes the wearer to perform engagement so as to bruxize. The softened artificial tooth 31 is formed by meshing with the tooth 41 facing the artificial tooth 31 by being formed of an uncured resin at room temperature.

If the artificial tooth 31 can be molded, the practitioner takes out the denture 11 from the wearer and irradiates the artificial tooth 31 with light. For example, when the artificial tooth 31 is formed of an ultraviolet curable resin, the artificial tooth 31 is irradiated with an ultraviolet illuminator such as black light.
By this irradiation, since the artificial tooth 31 is in a cured state, the denture 11 can be brought into a good meshing state.
In this way, the denture 11 can satisfy the wearer's satisfaction by being able to fit the wearer's engagement in a short period of time.

  When the artificial tooth 31 is formed of a thermosetting resin, when the molding of the artificial tooth 31 is completed, the practitioner takes out the denture 11 from the wearer's oral cavity, applies hot air, puts it into a furnace, or puts liquid (for example, The artificial tooth 31 can be hardened by being immersed in hot water.

Next, the case where the artificial tooth 31 is formed of a thermoplastic resin that becomes softened at 40 ° C. or higher will be described.
First, the artificial tooth 31 is heated to 40 ° C. or higher to be in a softened state. This heating applies hot air to the mounting part 21 or immerses the denture 11 in the liquid.

If the artificial tooth 31 is in the softened state, the artificial tooth 31 is formed by mounting the denture 11 on the jaw ridge of the wearer, as described with reference to FIG.
Then, the artificial tooth 11 is removed from the wearer, and the artificial tooth 31 is hardened by lowering the temperature of the artificial tooth 31 by applying cold air, immersing it in water, or leaving it at room temperature.
By doing so, since artificial tooth 31 will be in the state where it hardened, denture 11 can be made into a state with good meshing.

In the first and second embodiments, the artificial teeth 30 and 31 or the denture base 20 and 20x are the dentures 10 and 11 that are softened. However, the artificial tooth 31 and the denture base 20 may be combined. Is possible.
By doing so, it is possible to make a denture that can be fitted to the wearer's ridge and that has good meshing in a short period of time.

  In addition, although the dentures 10 and 11 which concern on this Embodiment 1, 2 were the complete dentures for the lower jaw, it can also be made into the complete denture for the upper jaw. Moreover, the denture of this invention can also be made into a partial denture. The denture base and artificial teeth of the present invention can also be a denture base temporomandibular joint splint, a sleeping mouthpiece, a whitening splint, or a sleep apnea syndrome splint. Furthermore, the denture base of the present invention can be applied to HOTZ floors, intraoral cines, and the like.

  The present invention can be used as a first-aid treatment in a dental clinic when a wearer has damaged a denture, or as a first-aid treatment in an undeveloped area where a dental clinic is not nearby. Is preferred.
