Description

  The present invention relates to a denture with a denture provided with an artificial tooth and a denture base that supports the artificial tooth.

  It is difficult to investigate the identity of a victim who has been injured or died in an accident or disaster if he does not carry a driver's license or insurance card. In such a case, for example, according to the personal data storage device described in Patent Document 1, the dental prosthesis incorporates an element that stores personal data such as name, blood type, and past disease. Even when an emergency medical procedure cannot be performed directly, it is possible to take an appropriate procedure quickly by taking out the stored contents of the element.

Japanese Patent Laid-Open No. 7-241301

  In the personal data storage device described in Patent Document 1, since the element is built in the dental prosthesis, it is possible to confirm the identity from dead bodies, severely damaged bodies, unidentified bodies, etc. In addition, it seems that there are various ways to use even when the wearer can be active.

  However, in Patent Document 1, when data that can identify an individual is read from an element, if the element is provided with a connector, the data is read by directly connecting an external connector to the terminal, or the element is a transmission type. If the stored information is transmitted, the information is read out by receiving the transmitted stored information. Therefore, when the wearer can be active, the data is read from the element incorporated in the dental prosthesis. It can be difficult.

When connecting an external connector directly to a terminal, it is necessary to put a cable connected to the end of the connector into the oral cavity, and if the signal from the element is weak, place the receiver into the oral cavity. It is necessary to put in.
Therefore, the personal data storage device described in Patent Document 1 is premised on a state in which the wearer can no longer be active, and is not assumed to be used in a state in which the wearer can be active.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a denture that can easily identify a wearer's individual regardless of the state of the wearer.

  The denture of the present invention is information read by an information reader, and an information storage body in which information for specifying a wearer is stored is an artificial tooth, a denture base that supports the artificial tooth, and supports the denture base It is characterized by being incorporated in a clasp for locking to a bar or an abutment tooth.

  According to the denture of the present invention, since the denture is an artificial tooth provided on the denture base, it can be easily removed from the oral cavity, so there is no need to put an information reader in the oral cavity, The plate denture can be removed from the oral cavity and taken near the information reader to perform the reading operation. Therefore, information can be easily read out not only in a state in which the wearer is injured or dead but cannot be active, but also in a state in which the wearer is active.

  The artificial tooth incorporating the information storage body is preferably formed in a different color from other artificial teeth supported on the denture base. Since it is possible to determine whether or not the information storage body is built in according to the color of the artificial tooth without providing irregularities for identifying the artificial tooth, the wearer does not feel uncomfortable. Moreover, it can color in a simple process rather than providing an artificial tooth with a stamp.

  The artificial tooth containing the information storage body is preferably formed by mixing a coloring material with a molding material. Since the coloring material is simply mixed with the molding material for forming the artificial tooth, it is possible to easily perform coloring for distinguishing from other artificial teeth.

  The information storage body is preferably a transmitting element that transmits information specifying the wearer as a radio signal. Even if the radio wave from the transmitting element built into the artificial tooth or denture base is weak, the denture base can be removed from the oral cavity and taken close to the information reader, so the radio signal from the transmitting element The information that can identify the wearer can be read out.

  It is desirable that the denture base incorporating the transmitting element is provided with an antenna for supplying electromotive force to the transmitting element and transmitting information from the transmitting element. By incorporating the transmitting element in the denture base and embedding the antenna, the reach of the radio wave from the transmitting element can be extended.

  If the optical storage information is written on the carrier as information for specifying the wearer, the information storage body does not break down, so that the information can be read reliably.

  According to the denture of the present invention, since it can be easily removed from the oral cavity, it is easy not only for the wearer to be injured or dead, but also for the wearer to be active. Can be read out easily to identify the individual of the wearer regardless of the state of the wearer.

(Embodiment 1)
A safety confirmation system according to Embodiment 1 of the present invention will be described with reference to the drawings.
A safety confirmation system 10 shown in FIG. 1 is capable of detecting the activity of a target person such as an elderly person or a care recipient and confirming the safety of the target person.

  The safety confirmation system 10 includes a denture with a built-in transmitting element 20 as an information storage body, a sensor 30 that functions as an information reading device that detects a signal from the transmitting element, and a detection notification from the sensor 30 on a telecommunication line. The communication apparatus 40 which transmits to the internet W which is an example, and the management server 50 which confirms a subject's safety based on the detection notification from the internet W are provided.

  The denture denture 20 can be a partial denture called a local denture or a partial denture worn by a subject (wearer), a full denture called a full denture or a complete denture, or the like. In the present embodiment, as shown in FIG. 2 (A), the teeth of all the upper jaws are artificial teeth 22, and these artificial teeth 22 are dentured dentures 20 supported by a denture base 21.

  In the bedded denture 20, the transmitting element T is embedded in the artificial tooth 22a of the upper left 6th. The artificial tooth 22 a in which the transmitting element T is embedded is formed in a different color from the other artificial teeth 22 supported on the denture base 21. In the first embodiment, the artificial teeth 22a are colored red while the other artificial teeth 22 are yellowish white. This coloring can be formed by mixing the coloring material with the molding material when the artificial tooth 22a is resin-molded. In addition, since the color of the artificial tooth 22a should just distinguish with other artificial teeth 22 other than red, it can be set as the change of blue, green, lightness and the like.

The transmitting element T is accommodated in a recess 22b provided at the center of the artificial tooth 22a. The recess 22b in which the transmitting element T is accommodated is filled with resin as a lid. The transmitting element T may be a non-contact passive tag type RFID tag.
In this transmitting element T, identification information (ID information) for specifying an individual, name, address, date of birth, gender, blood type, and the name of a hospital that identifies the dental clinic involved in treatment are identified. Personal information such as codes and medical history are stored if the capacity is sufficient. Various information stored in the transmitting element T is transmitted to the sensor 30 by irradiating the transmitting element T with radio waves from the sensor 30 to obtain an electromotive force.

  If the sensor 30 can read a signal (various information) from the transmitting element T embedded in the denture 20 by transmitting a radio wave, the sensor 30 outputs the signal to the communication device 40 as a detection notification. Further, the sensor 30 outputs a non-detection notification to the communication device 40 when the signal cannot be read. The detection notification includes information indicating that the transmission element T has been detected, identification information from the transmission element T, and personal information. The non-detection notification is information indicating that the transmission element T can no longer be detected and identification information from the transmission element T. The sensor 30 according to the first embodiment is provided in a container 60 that houses a denture 20 that is a dental prosthesis.

  The container 60 is a denture case with a lid formed in a substantially semicircular shape in plan view as shown in FIG. The sensor 30 is disposed on the bottom surface of the container 60. The container 60 can be a cleaning container as well as a simple storage container. The power source of the container 60 can be a battery or can be supplied from a power line.

  As shown in FIG. 1, the communication device 40 transmits a detection notification from the sensor 30 to the management server 50 connected to the Internet W. The communication device 40 and the sensor 30 can be wireless communication or wired communication. However, in order to facilitate the carrying of the container 60, it is desirable to use wireless communication.

  The management server 50 is a computer that functions as a safety confirmation device connected to the Internet W. The management server 50 functions as a safety confirmation device by operating a safety confirmation program. As shown in FIG. 4, the management server 50 includes a communication unit 51, a safety determination unit 52, a notification unit 53, a time setting unit 54, a calendar unit 55, and a storage unit 56.

  The communication unit 51 has a function of receiving information from the Internet W and outputting the information to the safety determination unit 52, or inputting information from the safety determination unit 52 and transmitting the information to the Internet W. The safety determination unit 52 determines that the target person is in an active state by receiving a detection notification or a non-detection notification within a predetermined time, or determines that the target person is in an active state. To do. When the safety determination unit 52 confirms safety, or when an abnormality is detected, the notification unit 53 notifies the relatives and related parties of the subject person. The notification unit 53 of the present embodiment has a function of notifying the safety state by e-mail. The time setting unit 54 sets a time when the safety determination unit 52 determines the safety of the subject person. The calendar unit 55 measures the date and time. The storage unit 56 stores not only programs such as OS and applications but also various setting information and statistical information.

  The operation and use state of the safety confirmation system according to Embodiment 1 of the present invention configured as described above will be described with reference to the drawings. The target person normally wakes up at 8 am and goes to bed at 9 pm. Accordingly, in the storage unit 56, 9 am is set in advance as the non-detection time when the notification of the non-detection notification is expected, and 10 pm is set as the detection time when the notification of the detection notification is expected. To do.

  As shown in FIG. 5, if a non-detection notification has been received last time, in the management server 50, the safety determination unit 52 reads “10 pm” that is the detection time from the storage unit 56 (step S <b> 10). The current time is read from the calendar unit 55 (step S20), and it is determined whether or not the current time has passed the detection time (step S30).

  The subject removes the bed denture 20 and stores it in the container 60 at 9:00 pm before going to bed. By storing the bed denture 20 in the container 60, the sensor 30 provided in the container 60 receives a signal from the transmitting element T provided in the bed denture 20. The sensor 30 outputs a signal from the transmitting element T to the communication device 40 as a detection notification. In the communication device 40, the detection notification is transmitted to the management server 50 via the Internet W.

  In the management server 50, when the current time has not passed the detection time, the safety determination unit 52 determines whether or not a detection notification has been received (step S40). The safety determination part 52 transfers to step S20, when the detection notification is not received.

  When the safety determination unit 52 receives the detection notification via the communication unit 51 before 10:00 pm, it can be confirmed that the subject has removed the bed denture 20 without any problem and has gone to bed. The notification unit 53 reads out the transmission destination address set in the storage unit 56 based on the identification information, and notifies that the target person is active and has no problem by e-mail (step S50).

  In step S30, the detection notification is not received by 10 pm, which is the detection time. Usually, the subject goes to bed at 9:00 pm, removes the denture 20 and stores it in the container 60. Therefore, the management server 50 side should be able to receive the detection notification. However, since the bedded denture 20 is not stored in the container 60 even at 10:00 pm, there is a possibility that something unexpected has occurred in the subject. Therefore, when the safety determination unit 52 determines that there is an abnormality, the notification unit 53 notifies the relatives and related parties that there is a problem by e-mail (step S60).

  In step S50, an e-mail indicating that there is no problem is transmitted to the related person. However, if there is a problem in receiving the daily e-mail, do not transmit the e-mail when there is no problem. It is also possible to make it.

  Next, the case where the management server 50 has received the detection notification last time will be described with reference to FIG. The safety determination unit 52 reads “9:00 am” that is the non-detection time from the storage unit 56 (step S110), reads the current time from the calendar unit 55 (step S120), and whether or not the current time becomes the non-detection time. Is determined (step S130).

  The subject takes out the denture 20 from the container 60 and attaches it at 8:00 am after waking up. When the bedded denture 20 is removed from the container 60, the sensor 30 provided in the container 60 cannot receive a signal from the transmitting element T provided in the bedded denture 20. The sensor 30 outputs a signal from the transmitting element T to the communication device 40 as a non-detection notification. The communication device 40 transmits a non-detection notification to the management server 50 via the Internet W.

  In the management server 50, when the current time has not passed the non-detection time, the safety determination unit 52 determines whether or not a non-detection notification has been received (step S140). The safety determination part 52 transfers to step S120, when the notification of detection is not received.

  When the safety determination unit 52 receives a non-detection notification via the communication unit 51 before 9:00 am, it can be confirmed that the subject has woken up without problems and has mounted the denture 20. The notification unit 53 reads out the transmission destination address set in the storage unit 56 based on the identification information, and notifies that the target person is active and has no problem by e-mail (step S150).

  In step S130, the non-detection notification is not received by 9:00 am, which is the non-detection time. Usually, the subject wakes up at 8:00 am and takes out the denture 20 from the container 60 and attaches it. It is a habit to do so, and the management server 50 side should be able to receive a non-detection notification after 8 am. However, since the bedded denture 20 is not stored in the container 60 even at 10:00 am, there is a possibility that something unexpected has occurred in the subject. Therefore, when the safety determination unit 52 determines that there is an abnormality, the notification unit 53 notifies the relatives and related parties that there is a problem by e-mail (step S160).

  In step S150, an e-mail indicating that there is no problem is transmitted to the related parties. However, as in step S50, if there is a problem in receiving daily e-mail, there is no problem. It is also possible not to send an e-mail.

  As described above, since the transmitting element T is provided in the dental prosthesis (bed denture 20) to be mounted in the oral cavity of the subject, the detection notification received via the communication device does not make the subject aware of it. Safety can be confirmed by the management server 50. In addition, since the denture 20 is worn by the subject every day, there is no need for a new habit. Therefore, it is possible to confirm the safety of the subject without being aware that the subject is being monitored.

  In addition, it is customary for the subject to remove the bed denture 20 when going to bed and store it in the container 60, and to take out and wear the bed denture 20 when waking up and eating. Such habits generally do not change every day. Therefore, by providing the sensor 30 in the container 60 that houses the dentures 20, the detection and non-detection of the transmitting element T can be reliably detected at least once a day.

Next, a method for setting the detection time and the non-detection time by the time setting unit 54 will be described with reference to FIG.
The time setting unit 54 reads the time at which the detection notification or the non-detection notification is received (hereinafter, this time is referred to as reception time) from the calendar unit 55 at the time of reception, and associates it with identification information for identifying the target person to store the storage unit 56. (Step S210).
The time setting unit 54 determines whether the reception time is stored for a predetermined period (step S220). For example, if the time setting unit 54 stores the time for one month, the latest reception time is extracted (step S230). For example, the latest reception time is 8:15 am.

  Then, the time setting unit 54 stores the time obtained by adding a little margin to the latest reception time, for example, the time obtained by adding 15 minutes in the storage unit 56 as the detection time and the non-detection time (step S240). Since the elderly have stable life rhythm and rarely vary extremely, the latest reception time may be set as the detection time or non-detection time. However, in the unlikely event, the storage or removal of the bed denture 20 has been delayed. Sometimes it is a false alarm, so it is desirable to add a margin.

  As described above, the time setting unit 54 sets the non-detection time or / and the detection time, so that the non-detection time can be customarily removed from the denture, and the detection time can be customarily included. Since it can be set as the time for mounting the denture, more accurate time can be set.

  In addition, when the subject is out, even if there is an accident or disaster and the identity cannot be heard from the subject, the bedded denture 20 is taken out from the subject's mouth and the reading device, etc. Thus, the information of the transmitting element T can be read. At this time, even if the subject (wearer) can be active, it is easy to read the data from the transmitting element T built in the denture 20 because the denture 20 is easy to remove. Moreover, since it can read with a reader in the state which removed the plate denture 20, it can be set as the state which made the bed denture 20 approached the reader. Therefore, it can be read even if the radio wave from the transmitting element T is weak. Therefore, it is possible to easily identify the individual of the wearer regardless of the state of the wearer.

Further, as shown in FIG. 2, the denture denture 20 determines whether or not the transmitting element T is built in depending on the color of the artificial tooth 22 without providing unevenness for identifying the artificial tooth 22a. Because it can, it does not give a sense of incongruity to the target wearer.
In addition, even if the wearer is unable to talk, it can be determined at a glance whether or not the bedded denture 20 having the built-in transmission element T is worn. The artificial tooth 22a having the built-in transmission element T can be specified and read in a state of being close to the reading device, and an individual can be specified.
Furthermore, in order to show that the transmitting element T is built in, the coloring material is simply mixed with the molding material for forming the artificial tooth 22a. Coloring to identify teeth can be performed.

(Embodiment 2)
A safety confirmation system according to Embodiment 2 of the present invention will be described with reference to the drawings.
In FIG. 8, the same components as those in FIG. In FIG. 8, the Internet W and the management server 50 are not shown.

  The safety confirmation system 11 shown in FIG. 8 is provided at various locations in the subject's residence H when there is a sufficient reach for the radio wave transmitted by the transmitting element T built in the denture 20x using the radio wave from the sensor 30 as an electromotive force. By locating the sensor 30 in the area, the activity in the subject's residence is monitored.

Since the denture 20x is a denture provided with an artificial tooth and a denture base that supports the artificial tooth, as shown in FIG. 9, not only can the transmitting element T be incorporated in the denture base, but also the antenna A is embedded. be able to. Therefore, the reach of radio waves from the transmitting element T can be extended.
In the house H shown in FIG. 8, the sensor 30 is installed in the entrance, toilet, kitchen, living room, Japanese-style room, Western-style room, hallway, and container 60. These sensors 30 are connected to the communication device 40 by wire or wirelessly.

  When the movement of the subject person in the residence H is closely monitored, information for distinguishing from the other sensors 30 is set in the sensor 30, and when the sensor 30 receives a signal from the transmitting element T, the transmitting element T The identification information of the sensor 30 is transmitted to the management server 50 via the communication device 40 as a detection notification. By transmitting the identification information of the sensor 30 to the management server 50, the management server 50 can grasp how the target person is moving in the residence H. Further, since the sensor 30 provided in the container 60 can be identified, the control of the management server 50 described in the first embodiment is also possible.

If it is only necessary to know that the subject is moving in the residence H, only the identification information of the transmitting element T detected by the sensor 30 is transmitted to the management server 50 as a detection notification.
In this way, by installing the sensor 30 in the residence H, the subject person who is active during the day is in a state of wearing the bed denture 20x, and thus no special custom is required. Therefore, the target person who is active in the residence H can be detected by the sensor 30 without being aware that the target person is being monitored.

  In the first and second embodiments, the case where the subject is indoors has been described as an example. However, the safety of the subject can be confirmed by appropriately arranging the sensor 30 outdoors and connecting to the communication device 40. .

(Embodiment 3)
A plate denture according to an embodiment of the present invention will be described with reference to the drawings.
In the first and second embodiments, the complete denture has been described as an example. In the third embodiment, a partial denture will be described as an example.

A plate denture 200 that is a partial denture includes an artificial tooth 201, a denture base 202 that supports the artificial tooth 201, a bar 203 that supports the denture base 202, and a clasp 204 for locking to an abutment tooth. ing.
As shown in FIGS. 10 to 13, the transmitting element T can be incorporated in any of these artificial teeth 201, denture bases 202, bars 203, or clasps 204.

10A and 10B, when the transmitting element T is built in the artificial tooth 201, a concave portion 201a is provided on the peripheral surface when the artificial tooth 201 is resin-molded. And the transmitting element T is inserted in this recessed part 201a, and the transmitting element T is sealed with resin. The recess 201a may be formed by cutting after the artificial tooth 201 is formed. In the resin sealing of the transmitting element T, a thermosetting resin is applied to the surface and the peripheral surface of the transmitting element T in a state where the transmitting element T is placed in the recess 201a, and the sealing resin is cured by heating. If there is no problem in the heat resistance of the transmitting element T, when the artificial tooth 201 is resin-molded, the transmitting element T may be inserted and molded. However, it is desirable to provide the recess 201a on the surface of the artificial tooth 201 because radio waves can easily pass therethrough.
It is desirable in terms of aesthetics to form the recess 201a on the inner surface. Further, if the sealing resin has the same color as the artificial tooth 201 and the boundary between the artificial tooth 201 and the sealing resin cannot be visually recognized, the recess 201a may be formed on the outer surface.

11A and 11B, when the transmitting element T is built in the denture base 202, a concave portion 202a is provided in the gingival portion when the denture base 202 is resin-molded. Then, the transmitting element T is inserted into the recess 202a, and the transmitting element T is sealed with resin. The recess 202a may be formed by cutting after the denture base 202 is formed. In the resin sealing of the transmitting element T, a thermosetting resin is applied to the surface and the peripheral surface of the transmitting element T in a state where the transmitting element T is placed in the recess 202a, and the sealing resin is cured by heating. If there is no problem with the heat resistance of the transmitting element T, when the denture base 202 is resin-molded, the transmitting element T may be inserted and molded. However, it is preferable to provide the concave portion 202a on the surface of the denture base 202 because radio waves can easily pass therethrough.
The recess 202a is preferably formed on the inner surface from the viewpoint of aesthetics. Further, if the sealing resin has the same color as the denture base 202 and the boundary between the denture base 202 and the sealing resin cannot be visually recognized, the concave portion 202a may be formed on the outer surface.

  12A and 12B, when the transmitting element T is built in the bar 203, when casting the bar 203, the recess 203a is formed in a portion where the width and depth where the transmitting element T can be arranged can be secured. Keep it. Then, the transmitting element T having an adhesive applied on the back surface is inserted and fixed in the recess 203a. The recess 203a may be formed by cutting the bar 203 and then cutting it. If there is no problem with the heat resistance of the transmitting element T, the transmitting element T may be formed when the bar 203 is cast. However, since the bar 203 is made of metal, there is a possibility that radio waves from the transmitting element T may not pass. Therefore, it is desirable to provide the recess 203a on the surface of the bar 203.

  13A and 13B, when the transmitting element T is built in the clasp 204, when the clasp 204 is cast, a concave portion is formed in the base end that is wider than the distal end that is locked to the abutment tooth. 204a is provided. And the transmitting element T which apply | coated the adhesive material on the back surface is inserted and fixed to this recessed part 204a. The recess 204a may be formed by cutting after the clasp 204 is cast. If there is no problem with the heat resistance of the transmitting element T, the transmitting element T may be formed when the clasp 204 is cast. However, since the clasp 204 is made of metal, there is a possibility that radio waves from the transmitting element T may not pass. Therefore, it is desirable to provide the recess 204a on the surface of the clasp 204.

  Thus, even if it is a base denture made into a partial denture, the transmitting element T can be incorporated in the artificial tooth 201, the denture base 202, the bar 203 or the clasp 204 constituting the partial denture. In FIGS. 10 to 13, the transmitting element T is incorporated in any one of the constituent members. However, the transmitting element T can be incorporated in any one, a combination thereof, or all. Further, the transmitting element T can be incorporated in a plurality of artificial teeth 201 or can be incorporated in both the left and right gingival portions of the denture base 202. When incorporating a plurality of transmitting elements T, it is possible to incorporate transmitting elements T having the same information or transmitting elements T having different information.

In FIG. 14C, a dot code is written on the plate P. The plate body P can be made of metal, resin, or ceramic. These optical reading information can be printed and engraved.

  The bar code indicates information by the respective line widths described in stripes. The barcode can be read by a barcode reader used in a convenience store or supermarket as an information reader. Since the barcode cannot carry much information, only the ID information may be used.

  The QR code is a two-dimensional array of rectangular cells in columns and rows. Although the QR code can be read by a mobile phone or the like, an information reading device sold as a QR code reader or a QR code scanner can be used.

  Here, the dot code will be described with reference to FIG. The dot code includes a reference key dot, a square with a side of 2 mm on the basis of the key dot, a grid dot, and 16 information dots indicating information. The information dot allows 48 bits of information to be carried on the plate body P. The dot code can be, for example, “Grid Input (registered trademark)”. When this dot code is printed with carbon ink, the carbon ink absorbs infrared rays, so that the dots can be read in black by taking an image with an infrared camera as an information reading device. However, since only the dot code is written on the plate P, the dot code may be printed with non-carbon ink and imaged with a visible light camera.

As shown in FIG. 16, the information storage body M shown in FIG. 14 (A) to FIG. 14 (C) in which the optically read information is carried on the plate body P includes an artificial tooth 201, a denture base 202, a bar 203 and the clasp 204.
In the third embodiment, as described with reference to the transmitting element as an example, the information storage body M is inserted into the recesses 201a to 204a of each part, and the information storage body M is sealed with resin, or the information storage is performed. The information storage body M can be accommodated by applying an adhesive to the back surface of the body M and fixing it to the recesses 201a to 204a.

  In this case, since the information storage body M needs to be read from the outside, the sealing resin is a transparent resin or a resin that transmits the reading light when cured.

  Although the information storage body M carrying the optically read information on the plate body P is inferior in storage capacity to the transmitting element, the information storage body M is built in the denture base 200 so that it can be easily taken out to identify an individual. can do. Further, unlike the transmitting element that is a semiconductor, the information storage body M does not break down and has high heat resistance, so that the information is not destroyed due to high temperature when the information storage body M is sealed. . Even if the surface of the sealing resin is contaminated and cannot be read, the surface of the sealing resin only needs to be washed, so that the reading operation can be easily recovered.

  When the information storage body M is built in the artificial tooth 201 or the denture base 202 made of resin, the information storage body M is sealed with resin, so that durability can be increased. Further, when the information storage body M is built in the bar 203 or the clasp 204, the information storage body M is built in with the adhesive on the back surface of the information storage body M, and the front surface is exposed, so there is no sealing resin. High reading accuracy.

  When the information storage body M is built into the denture base 200, it is built into any of the respective components (artificial teeth 201, denture base 202, bar 203, clasp 204), combined, or built into all. Can be. In addition, the information storage body M can be incorporated in a plurality of artificial teeth 201 or can be incorporated in both the left and right gingival portions of the denture base 202. When incorporating a plurality of information storage bodies M, it is possible to incorporate information storage bodies M having the same information or information storage bodies M having different information.

Thus, even if the subject (wearer) can be active by reading the information carried by the information storage body M incorporated in the bed denture with the reading device, the bed denture 200 can be removed. Since it is simple, it is easy to read information from the information storage body M built in the denture base 200. Therefore, it is possible to easily identify the individual of the wearer regardless of the state of the wearer.
In the fourth embodiment, the partial denture is described as an example. However, the information storage body M may be entirely incorporated in the artificial tooth or denture base of the denture.

  The present invention is suitable for elderly people, care recipients, and other wearers who are wearing dentures.
