Description

[Technical Field]

[0001] The present invention relates to a tooth-preserving device for preserving teeth and a method for manufacturing the tooth-preserving device. [Background technology]

[0002] Traditionally, when teeth were lost, they were discarded rather than kept. In particular, when baby teeth were replaced by permanent teeth, it was customary to throw the lower baby teeth onto the roof and the upper baby teeth under the veranda.

[0003] However, due to changes in living environments, there were no longer any verandas, and the question arose of what to do with lost baby teeth, so the practice of storing them began.

[0004] For this reason, for example, Japanese Patent Application Laid-Open No. 2022-40513 discloses a device for storing baby teeth, which is characterized in that it "has at least 10 small containers with different identifiers attached thereto, and a correspondence presentation element that presents to the user information indicating the correspondence between the position of each tooth in the oral cavity and the identification element, wherein each of the at least 10 small containers has an upper tooth storage container with an opening, a lower tooth storage container with an opening, and a single lid that has a first closing part that engages with the opening of the upper tooth storage container to close the opening, and a second closing part that engages with the opening of the lower tooth storage container to close the opening."

[0005] The above invention comprises at least 10 small containers each having a different identifier attached thereto, and a booklet corresponding to a correspondence presentation element that presents to the user information indicating the correspondence between the position of each tooth in the oral cavity and the identification element. However, it is necessary to record in the booklet each and every one of the numerous small containers in which a baby tooth is located, and when the user wishes to view the baby tooth, it is necessary to check the description in the booklet, which is extremely disadvantageous and inconvenient.

[0006] Furthermore, if there are brothers or sisters and each of them stores their baby teeth in the same small container, it is difficult to identify at a glance whose baby tooth a lost tooth is and where the baby tooth comes from. [Prior art documents] [Patent documents]

[Figure 2] FIG. 1 is a conceptual diagram of the inside of a user's oral cavity. [Figure 3] FIG. 1 is a conceptual diagram showing the boundary between the upper right front tooth and the upper gum. [Figure 4] FIG. 1 is a conceptual diagram showing the boundary between the lower right front tooth and the lower gum. [Figure 5] FIG. 10 is a conceptual diagram showing user oral cavity data of a user. [Figure 6] FIG. 1 is a conceptual diagram showing data on a tooth storage device. [Figure 7] A is a conceptual diagram showing the state of manufacturing a tooth-preserving device with a 3D printer. B is a conceptual diagram showing the state of using a removal device.

[0019] The tooth preservation device 10 of this embodiment will be described below with reference to the illustrated embodiment. The tooth preservation device 10 of this embodiment is capable of preserving lost teeth of a user 11, and is particularly suitable for preserving the baby teeth of the user 11. The tooth preservation device 10 of this embodiment has an upper jaw portion 20 and a lower jaw portion 70. The tooth preservation device 10 is preferably made of synthetic resin, for example, ultraviolet-curing resin for 3D printers.

[0020] The upper jaw portion 20 is an imitation of the upper jaw 200 in the oral cavity of the user 11, and is preferably accurately imitated by scanning the oral cavity, which is measured in three dimensions, as described below. Similarly, the lower jaw portion 70 is an imitation of the lower jaw 270 of the user 11, and is preferably accurately imitated by scanning the oral cavity, as described above. Note that, as described below, it is also preferable to take molds of the upper jaw portion 20 and the lower jaw portion 70 using impression materials.

[0021] Here, the user 11 is preferably an adult, but is preferably a user 11 in a state where all of the baby teeth have not yet fallen out. This is because by accurately scanning or taking a mold of the oral cavity at this point, it is possible to recreate the oral cavity of the user 11 as a child with all of the baby teeth.

[0022] The upper jaw portion 20 also has an upper gum portion 30 for accommodating the user's 11's lost teeth, particularly those that grew on the upper side of the user 11. The upper gum portion 30 is arch-shaped to fit along the upper gum 230, which is the user's upper gum, and has upper hole portions 40 for accommodating the user's 11's lost teeth. In this embodiment, the upper hole portions 40 may include a first upper hole portion 41, a second upper hole portion 42, a third upper hole portion 43, a fourth upper hole portion 44, a fifth upper hole portion 45, a sixth upper hole portion 46, a seventh upper hole portion 47, an eighth upper hole portion 48, a ninth upper hole portion 49, and a tenth upper hole portion 50, but are not limited to these. It is preferable that the upper hole portions 40 include at least one of these. This number preferably depends on the number of teeth that the user 11 actually had. Furthermore, the first upper hole portion 41, the second upper hole portion 42, the third upper hole portion 43, the fourth upper hole portion 44, the fifth upper hole portion 45, the sixth upper hole portion 46, the seventh upper hole portion 47, the eighth upper hole portion 48, the ninth upper hole portion 49, and the tenth upper hole portion 50 preferably have a depth sufficient to accommodate the placement of the teeth therein, and may also have a bottom portion, and preferably each open to penetrate the upper gum portion 30 (not shown).

[0023] Furthermore, the shape of the hole in the upper hole portion 40 is modeled after the outer shape of the teeth that actually grew in the user 11, and the shape is unique to the user 11. Therefore, even if someone else's teeth are placed in the upper hole portion 40, they may not fit together, and it may not be possible to place them in the upper hole portion 40.

[0024] In other words, the shapes of the holes in the upper hole portion 40, namely the first upper hole portion 41, the second upper hole portion 42, the third upper hole portion 43, the fourth upper hole portion 44, the fifth upper hole portion 45, the sixth upper hole portion 46, the seventh upper hole portion 47, the eighth upper hole portion 48, the ninth upper hole portion 49, and the tenth upper hole portion 50, are modeled after the shapes of the teeth that actually grew in the user 11, and if the missing tooth is, for example, a front tooth, the first upper hole portion 41 can be positioned at a location corresponding to the position of the upper front tooth 241 so that the missing upper front tooth 241 can be fitted into the first upper hole portion 41. This means that it may not fit with someone else's teeth, and it is unlikely that someone else's teeth will be mistakenly placed in any of the first upper hole portion 41, second upper hole portion 42, third upper hole portion 43, fourth upper hole portion 44, fifth upper hole portion 45, sixth upper hole portion 46, seventh upper hole portion 47, eighth upper hole portion 48, ninth upper hole portion 49, or tenth upper hole portion 50 of the upper hole portion 40. Also, as described above, the upper front teeth 241 of the user 11 will be placed in the first upper hole portion 41, and it is unlikely that they will be placed in the other second upper hole portion 42, third upper hole portion 43, fourth upper hole portion 44, fifth upper hole portion 45, sixth upper hole portion 46, seventh upper hole portion 47, eighth upper hole portion 48, ninth upper hole portion 49, or tenth upper hole portion 50.

[0025] For example, the expression "the outer shape 241b, which is the hole shape of the first upper hole portion 41 in the upper hole portion 40, follows the outer shape 241a" means that the outer shape 241b of the first upper hole portion 41 matches the outer shape 241a, which is a shape defined to surround the periphery of the right front tooth 241 at the boundary portion X1 (see FIG. 3) between the upper gum 230 of the upper jaw 200 of the user 11 and the upper right front tooth 241 located on the upper gum 230. The same applies to the other second upper hole portion 42, third upper hole portion 43, fourth upper hole portion 44, fifth upper hole portion 45, sixth upper hole portion 46, seventh upper hole portion 47, eighth upper hole portion 48, ninth upper hole portion 49, and tenth upper hole portion 50.

[0026] The maxillary portion 20 also has a hard palate portion 60 that imitates the hard palate 260 of the user 11. The hard palate portion 60 is arranged inside the arch-shaped upper gum portion 30 so as to fit along the upper gums 230 of the maxillary portion 200 of the user 11. As described above, the hard palate portion 60 preferably imitates the hard palate 260 of the user 11, and particularly preferably has a pattern portion 65 that imitates the pattern 265 of the hard palate 260. This pattern portion 65 is unique to the user 11 and may appear when the user 11's baby teeth erupt. The wrinkles on this pattern portion 65 vary from person to person, and for example, relatives may be able to identify an individual by the wrinkles on this pattern portion 65.

[0027] The lower jaw portion 70 has a lower gum portion 80 for accommodating missing teeth of the user 11, particularly teeth that grew below the user 11. The lower gum portion 80 is arch-shaped to fit along the lower gum 280, which is the gum under the user 11, and has lower hole portions 90 for accommodating missing teeth of the user 11. In this embodiment, the lower hole portions 90 may include a first lower hole portion 91, a second lower hole portion 92, a third lower hole portion 93, a fourth lower hole portion 94, a fifth lower hole portion 95, a sixth lower hole portion 96, a seventh lower hole portion 97, an eighth lower hole portion 98, a ninth lower hole portion 99, and a tenth lower hole portion 100, but are not limited to these, and it is preferable that the lower hole portion 90 include at least one of these. However, this preferably depends on the number of teeth that actually grew in the user 11. In addition, the first lower hole portion 91, the second lower hole portion 92, the third lower hole portion 93, the fourth lower hole portion 94, the fifth lower hole portion 95, the sixth lower hole portion 96, the seventh lower hole portion 97, the eighth lower hole portion 98, the ninth lower hole portion 99, and the tenth lower hole portion 100 have a depth sufficient to allow the teeth to be positioned therein, and it is preferable that they each open so as to penetrate the lower gum portion 80. Generally, there are a total of 20 baby teeth, so in this embodiment, the upper hole portion 40 has the first upper hole portion 41, the second upper hole portion 42, the third upper hole portion 43, the fourth upper hole portion 44, the fifth upper hole portion 45, the sixth upper hole portion 46, the seventh upper hole portion 47, the eighth upper hole portion 48, the ninth upper hole portion 49, and the tenth upper hole portion 50, and the lower hole portion 90 has the first lower hole portion 91, the second lower hole portion 92, the third lower hole portion 93, the fourth lower hole portion 94, the fifth lower hole portion 95, the sixth lower hole portion 96, the seventh lower hole portion 97, the eighth lower hole portion 98, the ninth lower hole portion 99, and the tenth lower hole portion 100, which total 20 holes, but this is not limited to this as there are individual differences.

[0028] Furthermore, the shape of the hole in the lower hole portion 90 is modeled after the outer shape of the teeth that actually grew in the user 11, and this outer shape is unique to the user 11. Therefore, even if someone else's teeth are placed in the lower hole portion 90, they will not fit together and cannot be placed in the lower hole portion 90.

[0029] That is, the shapes of the holes in the lower hole portion 90, namely the first lower hole portion 91, the second lower hole portion 92, the third lower hole portion 93, the fourth lower hole portion 94, the fifth lower hole portion 95, the sixth lower hole portion 96, the seventh lower hole portion 97, the eighth lower hole portion 98, the ninth lower hole portion 99, and the tenth lower hole portion 100, are modeled after the shapes of the teeth that actually grew in the user 11, and if the missing tooth is, for example, a lower front tooth 291, the missing lower front tooth 291 can be positioned so that it fits into the first lower hole portion 91 positioned at a position corresponding to the position of the lower front tooth 291. The same applies to the other teeth of the user 11 described below.

[0030] This means that it is unlikely that it will fit with someone else's teeth, and it is unlikely that someone else's teeth will be mistakenly placed in any of the first lower hole portion 91, the second lower hole portion 92, the third lower hole portion 93, the fourth lower hole portion 94, the fifth lower hole portion 95, the sixth lower hole portion 96, the seventh lower hole portion 97, the eighth lower hole portion 98, the ninth lower hole portion 99, and the tenth lower hole portion 100 in the lower hole portion 90. Also, as described above, in the case of the lower front tooth 291 of the user 11, it will be placed in the first lower hole portion 91, and it is unlikely that it will be placed in the other second lower hole portion 92, the third lower hole portion 93, the fourth lower hole portion 94, the fifth lower hole portion 95, the sixth lower hole portion 96, the seventh lower hole portion 97, the eighth lower hole portion 98, the ninth lower hole portion 99, and the tenth lower hole portion 100.

[0031] For example, the expression "the outer shape 291b, which is the hole shape of the first lower hole portion 91 in the lower hole portion 90, follows the outer shape 291a" means that the outer shape 291b of the first lower hole portion 91 matches the outer shape 291a, which is a shape defined to surround the periphery of the lower right front tooth 291 at a boundary portion Y1 (see FIG. 4) between the lower gum 280 of the lower jaw 270 of the user 11 and the lower right front tooth 291 located on the lower gum 280. The same applies to the other second lower hole portion 92, third lower hole portion 93, fourth lower hole portion 94, fifth lower hole portion 95, sixth lower hole portion 96, seventh lower hole portion 97, eighth lower hole portion 98, ninth lower hole portion 99, and tenth lower hole portion 100.

[0032] Next, a method for producing the baby tooth preservation device 10 of this embodiment will be described. For example, when the baby teeth of the user 11 have all grown in, the shape of the oral cavity of the user 11 is scanned with an intraoral scanner. Alternatively, the shape of the oral cavity is molded using an impression material (intraoral shape acquisition step S101). This makes it possible to acquire the shape of the oral cavity of the user 11 to imitate the upper jaw portion 20 and the lower jaw portion 70. Note that, although a case where each hole portion has a total of 20 holes will be described, this is not limited to this, and it goes without saying that the number of holes depends on the number of teeth that the user 11 has.

[0033] Specifically, in the intraoral shape acquisition step S101, data is digitized as user oral cavity data 11D of the user 11, and data 200D of the shape of the upper jaw 200 or data 270D of the shape of the lower jaw 270 is acquired. The data 200D of the shape of the upper jaw 200 includes data 260D of the shape of the hard palate 260 and data 265D of the shape of its pattern 265. The data 270D of the shape of the lower jaw 270 also includes data 280D of the lower gums 280. It is preferable that these acquired data be stored in a storage device. Therefore, the positions, sizes, and shapes of the teeth can also be stored in the storage device. It is preferable that the storage device be a memory, a hard disk, or an SSD (solid state drive).

[0034] As described above, from data 200D of the shape of the upper jaw 200 and data 270D of the shape of the lower jaw 270 of the user 11 when all of the baby teeth have erupted, which were acquired in intraoral shape acquisition step S101, all data of the portions of the baby teeth that have erupted are deleted to generate data 40D of the upper hole portion 40 and data 90D of the lower hole portion 90 (baby tooth portion deletion and data conversion step S102). In other words, data 200D of the shape of the upper jaw 200 of the user 11 is arch-shaped to imitate the dentition of the user 11, and includes data 260D of the shape of the hard palate 260 and data 265D of the shape of its pattern 265. Furthermore, data 230D of the upper gums 230 of user 11 includes data of the user 11's fully grown baby teeth, for example (data 241D of the upper right front tooth 241, data 242D of the upper left front tooth 242, data 243D of the upper right lateral incisor 243, data 244D of the upper left lateral incisor 244, data 245D of the upper right canine 245, data 246D of the upper left canine 246, data 247D of the upper right first premolar 247, data 248D of the upper left first premolar 248, data 249D of the upper right second premolar 249, and data 250D of the upper left second premolar 250), and therefore data 40D of the upper hole portion 40 is constructed by deleting all the data for those teeth.

[0035] Data 270D of the shape of lower jaw 270 is arched to match the dentition of user 11, and includes data 280D of lower gums 280. Data 280D of lower gums 280 includes data of, for example, all of the user 11's fully grown baby teeth (data 291D of lower right front tooth 291, data 292D of lower left front tooth 292, data 293D of lower right lateral incisor 293, data 294D of lower left lateral incisor 294, data 295D of lower right canine 295, data 296D of lower left canine 296, data 297D of lower right first premolar 297, data 298D of lower left first premolar 298, data 299D of lower right second premolar 299, and data 300D of lower left second premolar 300), and therefore data 90D of lower hole portion 90 is configured by deleting all of the data for these portions.

[0036] Therefore, the data 40D of the upper hole portion 40 is converted to data including data 41D of the first upper hole portion 41, data 42D of the second upper hole portion 42, data 43D of the third upper hole portion 43, data 44D of the fourth upper hole portion 44, data 45D of the fifth upper hole portion 45, data 46D of the sixth upper hole portion 46, data 47D of the seventh upper hole portion 47, data 48D of the eighth upper hole portion 48, data 49D of the ninth upper hole portion 49, and data 50D of the tenth upper hole portion 50, as described below. The data 40D of the upper hole portion 40 can be configured. Similarly, data 60D of the hard palate portion 60 is provided inside data 30D of the upper gum portion 30, which has an arch shape similar to the dentition of the user 11. The data 60D of the hard palate portion 60 is converted to data 260D of the shape of the hard palate 260. Furthermore, data 65D of the pattern portion 65 that imitates the pattern of the hard palate of the user 11 is converted into data from data 265D of the shape of the pattern 265, and data 20D of the upper jaw portion 20 having these can be formed.

[0037] The data 90D of the lower hole portion 90 is digitized to include data 91D of the first lower hole portion 91, data 92D of the second lower hole portion 92, data 93D of the third lower hole portion 93, data 94D of the fourth lower hole portion 94, data 95D of the fifth lower hole portion 95, data 96D of the sixth lower hole portion 96, data 97D of the seventh lower hole portion 97, data 98D of the eighth lower hole portion 98, data 99D of the ninth lower hole portion 99, and data 100D of the tenth lower hole portion 100, and data 70D of the mandible portion 70 having these can be constructed (deciduous tooth portion removal and digitization step S102).

[0038] By the above-mentioned primary tooth portion removing and data conversion step S102, the data 40D of the upper hole portion 40 is converted into data 10D of the tooth preservation device 10 so as to imitate the outer shape of the teeth of the user 11. That is, the data 241E of the outer shape 241b of the first upper hole portion 41 is converted into data so as to have a shape imitating, for example, the outer shape 241a of the upper right front tooth 241 of the user 11. Furthermore, the data 242E of the outer shape 242b of the second upper hole portion 42 is converted into data so as to have a shape imitating, for example, the outer shape 242a of the upper left front tooth 242 of the user 11. Furthermore, the data 243E of the outer shape 243b of the third upper hole portion 43 is converted into data so as to have a shape imitating, for example, the outer shape 243a of the upper right lateral incisor 243 of the user 11. Data 244E of the outer shape 244b of the fourth upper hole portion 44 is converted into data so as to have a shape that imitates, for example, the outer shape 244a of the upper left lateral incisor 244 of the user 11. Data 245E of the outer shape 245b of the fifth upper hole portion 45 is converted into data so as to have a shape that imitates, for example, the outer shape 245a of the upper right canine 245 of the user 11. Data 246E of the outer shape 246b of the sixth upper hole portion 46 is converted into data so as to have a shape that imitates, for example, the outer shape 246a of the upper left canine 246 of the user 11. Data 247E of the outer shape 247b of the seventh upper hole portion 47 is converted into data so as to have a shape that imitates, for example, the outer shape 247a of the upper right first premolar 247 of the user 11. Data 248E of the outer shape 248b of the eighth upper hole portion 48 is converted into data so as to have a shape that imitates, for example, the outer shape 248a of the upper left first premolar 248 of the user 11. Data 249E of the outer shape 249b of the shape of the ninth upper hole portion 49 is converted into data so as to have a shape that imitates, for example, the outer shape 249a of the upper right second premolar 249 of the user 11. Data 250E of the outer shape 250b of the tenth upper hole portion 50 is converted into data so as to have a shape that imitates, for example, the outer shape 250a of the upper left second premolar 250 of the user 11.

[0039] Similarly, by the above-described primary tooth portion removing and data conversion process, the data 90D of the lower hole portion 90 is converted into data so as to have a shape that imitates the outer shape of the teeth of the user 11. That is, data 291E of the outer shape 291b of the first lower hole portion 91 is converted into data so as to have a shape that imitates the outer shape 291a of the teeth of the user 11 after removing the lower right front tooth 291 of the user 11. Furthermore, data 292E of the outer shape 292b of the second lower hole portion 92 is converted into data so as to have a shape that imitates the outer shape 292a of the teeth of the user 11 after removing the lower left front tooth 292 of the user 11. Furthermore, data 293E of the outer shape 293b of the third lower hole portion 93 is converted into data so as to have a shape that imitates the outer shape 293a of the teeth of the user 11 after removing the lower right lateral incisor 293 of the user 11. Data 294E of the outer shape 294b of the fourth pre-hole portion 94 is converted into data so as to have a shape imitating the outer shape 394a of the user 11 by removing the lower left lateral incisor 294, for example. Data 295E of the outer shape 295b of the fifth pre-hole portion 95 is converted into data so as to have a shape imitating the outer shape 295a of the user 11 by removing the lower right canine 295, for example. Data 296E of the outer shape 296b of the sixth pre-hole portion 96 is converted into data so as to have a shape imitating the outer shape 296a of the user 11 by removing the lower left canine 296, for example. Data 297E of the outer shape 297b of the seventh pre-hole portion 97 is converted into data so as to have a shape imitating the outer shape 297a of the user 11 by removing the lower right first pre-molar 297, for example. For example, data 298E of the outer shape 298b of the eighth pre-hole portion 98 is converted into data so that the data has a shape imitating the outer shape 298a of the first pre-molar 298 of the lower left of the user 11. Data 299E of the outer shape 299b of the ninth pre-hole portion 99 is converted into data so that the data has a shape imitating the outer shape 299a of the second pre-molar 299 of the lower right of the user 11. Data 300E of the outer shape 300b of the tenth pre-hole portion 100 is converted into data so that the data has a shape imitating the outer shape 300a of the second pre-molar 300 of the lower left of the user 11. In this way, data 10D of the tooth preservation device 10 is created (deciduous tooth portion deleting and data conversion step S102).

[0040] Next, the data 10D of the tooth-storing device 10 obtained in the deciduous tooth portion deletion and digitization step S102 is sent to a so-called 3D printer 300, and the tooth-storing device 10 is printed out to form the tooth-storing device 10 (tooth-storing device forming step S103, see FIG. 7A). That is, all data of the erupted deciduous teeth portions are deleted from the shape data 200D of the upper jaw 200 and the shape data 270D of the lower jaw 270, and the data 40D of the upper hole portion 40, data 90D of the lower hole portion 90, and data 60D of the palate portion 60 consisting of data 260D of the shape of the hard palate 260 and data 265D of the shape of the pattern portion 65 are sent to the so-called 3D printer 300, and the tooth-storing device 10 is formed by printing out the upper jaw portion 20 and the lower jaw portion 70 (tooth-storing device forming step S103). In other words, the baby tooth portion removal and digitization step S102 involves inputting data acquired by an intraoral scanner into so-called data processing software, and recreating data by removing, for example, the baby teeth of the user 11 that have fully grown in, and drilling holes (baby tooth portion removal and digitization step S102). This regenerated data is then sent to a so-called 3D printer, and the upper jaw portion 20 and the lower jaw portion 70 are printed out to form the tooth-save device 10 (tooth-save device formation step S103). In this way, the tooth-save device 10 can be created through the above steps. Note that the upper jaw portion 20 and the lower jaw portion 70 of the tooth-save device 10 may be embedded in a so-called support material X. A removal step S104 may also be included in which this so-called support material X is removed using a removal device 400.

[0041] The upper hole portions 40 in the tooth-storage device 10 produced by the tooth-storage device production process described above are configured to follow the outer shapes of the respective upper teeth of the user 11.

The outer shape 248b of the eighth upper hole portion 48 is configured to follow, for example, the outer shape 248a of the upper left first premolar 248 of the user 11. The outer shape 249b of the ninth upper hole portion 49 is configured to follow, for example, the outer shape 249a of the upper right second premolar 249 of the user 11. The outer shape 250b of the tenth upper hole portion 50 is configured to follow the outer shape 250a of the upper left second premolar 250 of the user 11, for example.

[0042] The lower hole portions 90 are configured to follow the outer shapes of the respective lower teeth of the user 11. That is, the outer shape 291b of the first lower hole portion 91 is configured to follow the outer shape 291a of the lower right front tooth 291 of the user 11, for example. The outer shape 292b of the second lower hole portion 92 is configured to follow the outer shape 292a of the lower left front tooth 292 of the user 11, for example.

The outer shape 294b of the fourth lower hole portion 94 is configured to follow the outer shape 294a of the lower left lateral incisor 294 of the user 11, for example. The outer shape 295b of the fifth lower hole portion 95 is configured to follow the outer shape 295a of the lower right canine 295 of the user 11, for example. The outer shape 296b of the sixth lower hole portion 96 is configured to imitate, for example, the outer shape 296a of the lower left canine 296 of the user 11. The outer shape 297b of the seventh lower hole portion 97 is configured to imitate, for example, the outer shape 297a of the lower right first premolar 297 of the user 11. The outer shape 298b of the eighth lower hole portion 98 is configured to imitate, for example, the outer shape 298a of the lower left first premolar 298 of the user 11. The outer shape 299b of the ninth lower hole portion 99 is configured to imitate, for example, the outer shape 299a of the lower right second premolar 299 of the user 11. The outer shape 300b of the tenth lower hole portion 100 is configured to imitate, for example, the outer shape 300a of the lower left second premolar 300 of the user 11 (see FIG. 1 ).

[0043] The primary tooth storage device 10 can be used, for example, as part of preventative dental care for the user 11's oral cavity. When a dentist examines the user's oral cavity at a dental clinic, the dentist places the user's lost primary teeth in the corresponding hole in the upper hole 40 or the lower hole 90. Specifically, the upper hole 40 is configured to conform to the outer shape of the user's upper teeth, and the lower hole 90 is configured to conform to the outer shape of the user's lower teeth. Therefore, for example, the first upper hole 41 can accommodate the user's missing right upper front tooth 241. The second upper hole 42 can accommodate the user's missing left upper front tooth 242. The third upper hole 43 can accommodate the user's missing right lateral incisor 243. The fourth upper hole 44 can accommodate the user's missing left upper lateral incisor 244. The fifth upper hole 45 can accommodate, for example, a missing right canine tooth 245 of the user 11. The sixth upper hole 46 can accommodate, for example, a missing left canine tooth 246 of the user 11. The seventh upper hole 47 can accommodate, for example, a missing right first premolar tooth 247 of the user 11. The eighth upper hole 48 can accommodate, for example, a missing left first premolar tooth 248 of the user 11. The ninth upper hole 49 can accommodate, for example, a missing right second premolar tooth 249 of the user 11. The tenth upper hole 50 can accommodate, for example, a missing left second premolar tooth 250 of the user 11.

[0044] The first lower hole portion 91 can accommodate, for example, a missing right front tooth 291 of the user 11. The second lower hole portion 92 can accommodate, for example, a missing left front tooth 292 of the user 11. The third lower hole portion 93 can accommodate, for example, a missing right lateral incisor 293 of the user 11. The fourth lower hole portion 94 is configured to resemble the outer shape of the missing left lateral incisor 294 of the user 11. The fifth lower hole portion 95 can accommodate, for example, a missing right canine 295 of the user 11. The sixth lower hole portion 96 can accommodate, for example, a missing left canine 296 of the user 11. The seventh lower hole portion 97 can accommodate, for example, a missing right first bicuspid 297 of the user 11. The eighth lower hole portion 98 can accommodate, for example, a missing left first bicuspid 298 of the user 11. For example, the user's 11's missing right second premolar 299 can be placed in the ninth lower hole 99. The user's 11's missing left second premolar 300 can be placed in the tenth lower hole 50. In this way, missing teeth can be placed in their respective locations and fitted into their respective holes, so that only the missing teeth of that user 11 can be placed. Furthermore, because other people's teeth do not fit into these holes, there is little chance that other people's teeth will be mixed into the tooth preservation device 10 of this embodiment.

[0045] In addition to dentists, the user 11 or his / her guardian can also place a lost tooth in each hole in the tooth preservation device 10. If a tooth to be stored in the tooth preservation device 10 is lost, the data on the position, size, and shape of the lost tooth from the data on the shape of the upper jaw 200 or the data on the shape of the lower jaw 270 of the user 11 acquired in the intraoral shape acquisition process described above is stored in a storage device, so a replica of the lost tooth can be created by sending this data to the 3D printer described above, and the replica of the tooth can be placed in one of the holes.

[0046] The tooth preservation device 10 can accommodate only the teeth of a specific user 11, so it is clear at a glance whose teeth belong to whom, or which teeth are located in the specific holes mentioned above, so that the teeth can be identified at a glance. Also, it may be possible to distinguish whose teeth belong to whom by the appearance of the wrinkles in the patterned portion 65. [Explanation of symbols]
