Description

  The present invention relates to a denture having a marker with a denture identification information such as a manufacturer name on a resin floor that supports a crown, pontic, or artificial tooth.

  With the aging of society, as the number of elderly people increases, there are many people who wear dentures among elderly people who receive care. Against this backdrop, it is normal for a single caregiver to care for multiple elderly people, and after a meal, etc., the caregiver received and cleaned the floor denture from multiple caregivers. After that, it is returned to each care recipient. Therefore, it has been conventionally performed to mark the denture with a mark for identifying the owner. This conventionally practiced method includes, for example, a method of marking the name of the owner on the lingual side of the denture. However, this method has a problem that stress is concentrated on the engraved portion every time the wearer chews food, and the mastication portion is relatively easily damaged by repeated chewing.

  Furthermore, in recent years, product liability has become a question, dentures are not examples, and it has become necessary to specify the manufacturer's name on the dentures. For this reason, a method of entering the manufacturer's name and telephone number using a tape or printed material on a denture is also introduced, but the tape or printed material used is not approved as a dental material. is there.

  In addition, inventions and devices for embedding small pieces in which information is stored in a denture have been proposed, and a device for collecting a large amount of information in the small pieces to be embedded in a denture has been made. Examples of this invention and device include the invention described in Japanese Patent Application Laid-Open No. 11-253461 and the device described in Utility Model Registration No. 3080133.

In the invention described in Japanese Patent Laid-Open No. 11-253461, an embedded hole is formed in a resin floor of a denture, and a microchip or the like is embedded in the embedded hole, and then an immediate polymerization type is formed on the surface of the microchip or the like. A resin is applied and solidified.
In addition, the invention described in Utility Model Registration No. 3080133 discloses an embedding depression in a resin floor or crown of a denture, and after embedding an information description piece in the embedding depression, a transparent resin is used. Covering and fixing, and polishing the surface of the transparent resin.

The invention described in Japanese Patent Application Laid-Open No. 11-253461 reads the registration number of the denture owner with a microchip reader and specifies the owner of the denture. The utility model registration No. 3080133 The idea described in the gazette is to quickly and surely confirm the character information such as the owner's name, dental clinic name, medical record number, telephone number, and address.
JP-A-11-253461 Utility Model Registration No. 3080133

  However, not only natural teeth but also dentures, the tooth type occupies an important element for identifying an individual. In such a case, if the denture has an identification mark, The owner can be identified quickly. For that purpose, even if the denture is exposed to a state such as a high temperature different from the living environment, it is desired that the identification function of the identification mark attached to the denture is maintained. Further, it is desirable that such an identification mark can be attached even to a denture such as a mandibular incisor or a mandibular canine having a small area to find and a small plane portion. .

From this point of view, the invention described in Japanese Patent Application Laid-Open No. 11-253461 is inherently vulnerable to heat because it uses a microchip. Can only be embedded. In addition, even in the device described in Utility Model Registration No. 3080133, the information description piece used in the device includes characters such as the owner's name, dental clinic name, medical record number, telephone number, and address. Since the information is described, it must have a certain size and can be embedded in a denture, but the target denture is a denture with a large area such as a molar. In addition, the information piece is deformed or burned when exposed to high heat.
Furthermore, the microchip and the information-recording piece are not approved as a dental material, and even if they are coated with a resin or the like, the resin or the like may be peeled off or worn depending on the method of use or years of use. In some cases, food residues adhere to the oral cavity and are unsanitary. In addition, a dedicated reader is required to read the information written on the microchip, and a magnifying glass is required to read the information written on the information writing piece.

  Therefore, the present invention can be visually read even when exposed to high heat, can be attached even to a denture with a small area to be found and a small flat surface portion, and is legally permitted. It is an object of the present invention to provide a denture having an identification mark made of a dental material and a method for producing the same.

In order to achieve the above-mentioned object, the invention of a denture having identification information according to claim 1 of the present invention includes a crown made of porcelain or resin, or a bridge or artificial tooth comprising a crown and a pontic and an artificial tooth. In the denture having a resin bed that supports a dental prosthesis, a visible denture identification mark is attached to the surface of the crown and pontic and / or the vicinity of the lingual tooth neck of the surface of the resin bed. It is said.

(4) In addition, since the resin piece is made of the same material as the resin floor, the adhesiveness and adhesion are well integrated, and the exposed surface is kept smooth, and food residues adhere to it. The hygiene can be used in the same way as a normal resin bed.

Furthermore, in the invention of the manufacturing method according to claim 4 of the present application, the drawing is directly drawn on the surface of the crown with stain porcelain or dental stain, and in the manufacturing method of the invention of claim 5 is drawn on the surface of the crown. After engraving, stain porcelain or dental stain is embedded. Therefore, in the manufacturing method according to claim 4 of the present application, it is possible to easily manufacture a denture identification mark by proficiency. In the manufacturing method according to claim 5 of the present application, a line drawn with stain porcelain or dental stain is used. There is no bleeding.
And even if it is the manufacturing method of this-application Claim 4 or the manufacturing method of this-application Claim 5, after drawing, after glaze baking, self-glazing baking, or transparent resin application | coating, superposition | polymerization * grinding | polishing * glaze In order to perform a series of operations, the surface of the stain porcelain or dental stain is coated, and the stain porcelain or dental stain is firmly fixed to the surface of the crown.

  According to the sixth aspect of the present invention, since the resin piece is sandwiched between the polymerized first resin bed and the second resin bed, the resin piece is the first resin bed and the second resin bed. The two resin floors are integrated and firmly fixed. Further, the thickness of the resin piece is about 1 mm, and by reducing the thickness of the second resin floor on which the resin piece is temporarily placed, the wearer of the denture does not feel uncomfortable with the resin piece.

  As described above, the size of characters drawn on the crown is about 2 mm square in length and width, and the number of characters drawn on the crown is about 2 characters considering the size of the crown. If alphabets are used for these two characters, the number of combinations is 676. If the number of stain porcelain or dental stains is five, which is normally used, the amount of information that can be included in a denture identification mark Is 16,900 (676 × 5 × 5). Furthermore, if this information amount and the information amount of the resin piece embedded in the resin floor are combined, an infinite amount of information is given to the denture according to the present invention.

Of course, it is possible to give the owner's information to the denture identification mark, but the applicant of the present application considers adding the manufacturer's information to the denture identification mark. Even if the denture is exposed to high heat and the shape of the entire denture does not remain in its original shape, if the denture identification mark of one crown can be read, the manufacturer of the denture can be found from there. If the manufacturer of the denture is found out, the owner of the denture can be identified more reliably and more quickly than the case where the name is engraved by the chart held by the manufacturer from the tooth mold or the like. Because.
As described above, even if the information to be given to the denture identification mark is limited, the information of the denture identification mark has an infinite spread by associating with the other database.
