Description

  The present invention relates to a removable tooth tool that can be used for transformation at the time of an event, tooth-related fashion, and the like, and a method for manufacturing the same.

  As can be seen in the example of cosplay established in Japan with a focus on young people, humans have a universal sense of playfulness, such as wanting to be someone other than themselves, or wanting to surprise others by becoming someone else. For example, in an event or the like, it is often seen that a player is intimidated by stimulating the playfulness of the audience by disguise or transformation. Such transformations and disguises often involve props. For example, an instant transformation shirt (Patent Document 1) for instantly transforming and a hero instantaneous transformation method (Patent Document 2) have been proposed. You can get applause with the intentions of the participants by momentarily turning over these props such as clothes.

JP 2007-308856 A JP 2006-200103 A

The above transformation props are clothes, and the impression of the face cannot be changed greatly. There is a tooth to change the impression of the face. Since white clean teeth give a healthy and cheerful impression, many dental clinics use artificial teeth for cosmetic purposes. An artificial tooth is a ceramic shell (thin piece) affixed to the surface of one tooth. That is, attachment of an artificial tooth is performed by affixing the said white ceramic shell on the front surface of the front tooth which stands out, for example. For this reason, the artificial tooth cannot be easily attached and detached, and therefore cannot be applied to instantly transforming a participant in an event with the other party.
An object of the present invention is to provide a removable tooth tool and a method for manufacturing the same that can instantly change the impression given to the other party.

  The removable tooth tool of the present invention is detachably attached to a tooth. This detachable dental instrument includes a covering portion that continues to the palate while covering the front surface, the top portion, and the back surface of a living tooth, and one or more transformed teeth that are fixed to the covering portion. Is made of an integrally molded resin.

  With this configuration, the user can instantly wear the tooth tool by covering his / her teeth with the covering portion, and impress the other person with the unique transformed tooth. The transforming tooth is usually fixed to the front surface portion covering the front surface of the tooth (particularly the front tooth) in the covering portion. As a result, it is possible to impress the unexpectedness at various parties and so on, and to win the habit. And since the coating | coated part is made of resin, since elastic deformation ability is large, it can remove | separate easily from one's own tooth. That is, attachment and detachment can be performed easily and instantaneously by the action of one's hand. Here, the transforming tooth differs from a normal front tooth in at least one of a shape, a color, and a pattern, and refers to an unusual tooth aimed at receiving a partner (audience). The removable toothpaste may be the upper jaw or the lower jaw, but the upper teeth come out in front of the lower jaw, so the upper jaw is often the target in terms of impression to the other party.

  Said coating | coated part can cover the front teeth of the 1st-4th of the left, and the 1st-4th of the right, or several of the front teeth. As a result, the deformed tooth can be fixed at the position of the front tooth, which is easy to enter the partner's field of view.

  Said coating | coated part can be formed with transparent resin. Thus, the covering portion is hardly visible to the other party, and it can be made to think that the transformed tooth is really growing in the dentition of the user.

  In the covering portion, a portion covering any of the front teeth can be removed. As a result, it is possible to minimize the covering of one's teeth and to prevent discomfort even when worn for a long time. Also, since the user's actual teeth are shown to the other party (audience), the feeling of authenticity and authenticity that the other party receives can be enhanced.

  The removed portion can be the left first and right first covering portions. As a result, the tooth tool is mounted without covering the first two front teeth. For this reason, it is possible to strongly impress the other party that the two front teeth are in a natural state (a state where the front teeth are not covered with a transparent resin or resin). That is, by showing the user's natural teeth, it is easy to make an illusion that the transformed teeth are also the user's teeth. In addition, even for the user, the sense of restraint, the feeling of pressure, etc. can be reduced in the worn state.

  The manufacturing method of the removable tooth tool of this invention manufactures the removable tooth tool attached to a tooth so that attachment or detachment is possible. This manufacturing method includes a step of producing a plaster model of a user's tooth, a step of preparing a thermoplastic resin thin plate, a thermoplastic resin thin plate placed on the plaster model, and applying pressure while heating. Or, by sucking, deforming the thermoplastic resin thin plate and bringing it into close contact with the gypsum model, forming the covering part, removing the covering part from the gypsum model, shaping, and fixing the transformed tooth to the covering part And a step of performing.

  By the manufacturing method described above, the covering portion can be produced by integral molding with a thermoplastic resin, and the transformed teeth can be fixed thereto. The fixed position can be changed according to the object to be transformed with reference to the position of the occupying teeth of the idle or the position of the teeth of the Dracula. According to said method, a coating | coated part can be easily manufactured using the apparatus which produces a mouthpiece etc. A transforming tooth produced by an appropriate method including handmade can be fixed to the covering portion by hand. For fixing, a room temperature polymerization resin or the like having a proven record as a dental material can be used.

  In the process of making the user's tooth plaster model, the user adjusts the impression agent mailed from the supplier to the user according to the application to the supplier's website and puts it in the tray. The user can take a procedure that the user presses against his / her teeth, takes an impression of the tooth profile, and the supplier creates a plaster model based on the collected impression sent back to the supplier. . In this case, it is desirable to carefully explain how to collect impressions using an impression agent on the website. In addition, the supplier establishes a business relationship with a predetermined chain store, distributes a set necessary for collecting impressions to the chain store in advance, and sets the chain store in response to an application from the user to the website. A method may be used in which the user designates and purchases a set of impression collections. Also in this case, the user collects his / her own impression and sends the collected impression to the supplier. The subsequent steps are the same. Thereby, according to the request of the client in each place, the coating | coated part suitable for a client's tooth profile etc. can be produced. The transformation teeth can be selected according to the client's instructions by displaying many types of transformation teeth on the website.

  ADVANTAGE OF THE INVENTION According to this invention, the removable tooth tool and its manufacturing method which can be surprised by changing the impression given to a partner instantly can be obtained.

In the dental instrument 10, the remaining part other than the palate covering part 3 is the tooth covering part 4. The tooth covering part 4 is formed so as to cover the right 1st to right 4th and the left 1st to left 4th. The parts other than the transformation teeth 15 are all formed of a transparent resin that is integrally molded. Makeover teeth 15, and the front portion f of the right third R _3, and the front portion f of the left third L _3, to which is fixed one each. In the tooth covering portion 4, the symbol of the front surface portion f is used for the portion that contacts the tooth front surface, the symbol of the back surface portion b for the portion that contacts the tooth back surface, and the symbol of the top portion t for the portion that contacts and covers the tooth top portion. The tooth numbers such as R ₂ ( _second right tooth) and L ₂ (second left tooth) are assigned to each tooth.
The transformation tooth 15 has a length approximately twice that of a normal front tooth. The color of the transformation tooth 15 may be anything, but may be yellow, white, milky white, or the like. It may emit fluorescence. Alternatively, it may be a transformed tooth in which small jewelry such as glass balls and red balls are studded. The width is slightly larger than the normal front teeth, but the thickness is about 2 to 3 times.

FIG.1 (b) is sectional drawing of the tooth covering part of the 2nd right. According to FIG. 1 (b), the right second tooth R ₂ (the gap in FIG. 1 (b)) is covered (or surrounded) by the front surface portion f, the top portion t, and the back surface portion b. . The left and right Nos. 1 and 2 are plate-like, and the left and right Nos. 1 and 2 are covered in the same form as the tooth covering part of FIG.
