[0023] <Embodiment> Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0024] <Outline of manufacturing system> First, an overview of the manufacturing system according to this embodiment will be described.
[0025] The manufacturing system according to the embodiment includes a tomographic imaging apparatus, an information processing apparatus, and a manufacturing apparatus.
[0026] The tomographic imaging apparatus captures a tomographic image of a jawbone region, including the jawbone, of a body part of a subject by a predetermined method.
[0027] The information processing device outputs restorative prosthetic information regarding restorative prosthetics to be attached to at least one of the teeth and gums of the subject based on jawbone part shape information indicating the shape of the jawbone part included in the subject information regarding the subject output as imaged subject information from the tomography device, and gum information indicating the gums of the subject corresponding to the shape indicated by the jawbone part shape information.
[0028] The manufacturing device manufactures a restorative prosthesis based on the restorative prosthesis information output from the information processing device.
[0029] This allows the manufacturing system to generate restorative prosthetic information suited to the imaged patient.
[0030] The configuration of the manufacturing system according to the embodiment and the processing related to manufacturing a restorative prosthesis among the processing performed by an information processing device in the manufacturing system will be described in detail below.
[0031] <Manufacturing system configuration> The configuration of the manufacturing system according to the embodiment will be described below by taking the manufacturing system 1 as an example of the manufacturing system according to the embodiment. FIG.
[0032] The manufacturing system 1 includes, for example, a tomographic imaging apparatus 10, an information processing device 20, and a manufacturing device 30. The manufacturing system 1 may not include the tomographic imaging apparatus 10. The tomographic imaging apparatus 10 and the information processing device 20 may form an information processing system S as shown in FIG. 1. In this case, the manufacturing system 1 includes the information processing system S and the manufacturing device 30. The manufacturing system 1 may include other devices in addition to at least the information processing device 20 and the manufacturing device 30 out of the tomographic imaging apparatus 10, the information processing device 20, and the manufacturing device 30.
[0033] The manufacturing system 1 manufactures restorative prostheses to be attached to at least one of the teeth and gums of a person to be imaged by the tomographic imaging device 10. In the following, as an example, a case where the person to be imaged is the person to be imaged H shown in FIG. 1 will be described. The person to be imaged H may be any person as long as he or she can be imaged by the tomographic imaging device 10. The person to be imaged H is, for example, a patient of a dentist, but is not limited to this.
[0034] The tomographic imaging device 10 captures a tomographic image of a jawbone region including the jawbone among the regions of the subject H by a predetermined method. The tomographic imaging device 10 is, for example, a dental CT (Computed Tomography) device. In this case, the predetermined method is a CT image reconstruction method. The tomographic imaging device 10 may be a non-dental CT device, an MRI (Magnetic Resonance Imaging) device, or another device capable of capturing a tomographic image of the jawbone region by a predetermined method. Hereinafter, when a tomographic image of the subject H is referred to, it means a tomographic image of the jawbone region.
[0035] The tomographic imaging apparatus 10 is communicably connected to an information processing apparatus 20 via wire or wirelessly.
[0036] The tomographic imaging device 10 captures a tomographic image of the person H who is placed at a position and posture that can be imaged by the tomographic imaging device 10 in response to control from the information processing device 20. After capturing a tomographic image of the person H, the tomographic imaging device 10 generates person information based on the captured tomographic image. The person information is information about the person H. More specifically, the person information is information including jawbone part shape information indicating the shape of the jawbone part of the person H. The person information may be configured to include other information in addition to the jawbone part shape information. For example, when the person H has one or more teeth, the person information may include dentition information indicating the dentition of the person H, and when the person H does not have teeth, the person information may not include dentition information. The person information may also be configured to include gum information indicating the gums of the person H. The person information may also be configured to include skin information indicating the skin of the jawbone part of the person H. For example, the tomographic imaging apparatus 10 generates DICOM (Digital Imaging and Communications in Medicine) data as such imaged person information. Note that the tomographic imaging apparatus 10 may be configured to generate data in a format other than DICOM data as such imaged person information. In the following, as an example, a case where the tomographic imaging apparatus 10 generates DICOM data as such imaged person information will be described.
[0037] The tomographic imaging apparatus 10 generates DICOM data as imaged person information, and then outputs the imaged person information generated as DICOM data to the information processing apparatus 20.
[0038] Instead of being controlled by the information processing device 20, the tomographic imaging device 10 may be configured to capture a tomographic image of the person H to be imaged in response to an operation received from a user via a hardware key, software key, or the like possessed by the tomographic imaging device 10. In this case, the tomographic imaging device 10 may be configured to output the generated imaged person information to the information processing device 20 via communication, or may be configured to output the generated imaged person information to an external storage device (or storage medium) such as a flash memory for storage. When the tomographic imaging device 10 outputs the imaged person information to the storage device for storage, the information processing device 20 acquires the imaged person information via the storage device connected by the user.
[0039] The information processing device 20 is, for example, a workstation, a desktop PC (Personal Computer), a notebook PC, etc. Note that the information processing device 20 may be, instead of these, other information processing devices such as a tablet PC, a multi-function mobile phone terminal (smartphone), a mobile phone terminal, a PDA (Personal Digital Assistant), etc.
[0040] The information processing device 20 controls the tomographic imaging device 10. The information processing device 20 outputs restorative prosthetic information regarding restorative prosthetics to be attached to at least one of the teeth of the person H and the gums of the person H, based on the imaged person information output as DICOM data from the tomographic imaging device 10, gum information indicating the gums of the person H, and the accepted operation. Here, the restorative prosthetics to be attached to the teeth of the person H are, for example, silver fillings, etc. The restorative prosthetics to be attached to the gums of the person H are, for example, full dentures. The restorative prosthetics to be attached to both the teeth of the person H and the gums of the person H are, for example, partial dentures.
[0041] Here, the information processing device 20 generates three-dimensional image data indicating the shape of the restorative prosthesis as the restorative prosthesis information. For example, the information processing device 20 generates STL (Standard Triangulated Language) data indicating the shape of the restorative prosthesis as the three-dimensional image data. Note that the information processing device 20 may be configured to generate data in a format other than STL data as the three-dimensional image data.
[0042] The information processing device 20 outputs the generated restorative prosthetic information to the manufacturing device 30.
[0043] The manufacturing apparatus 30 is communicably connected to the information processing apparatus 20 wirelessly or via wires.
[0044] The manufacturing device 30 manufactures a restorative prosthesis having a shape indicated by the restorative prosthesis information based on the restorative prosthesis information output from the information processing device 20. The manufacturing device 30 is, for example, a 3D printer. Note that the manufacturing device 30 may be other devices capable of manufacturing a restorative prosthesis based on the restorative prosthesis information, such as a CAM (Computer Aided Manufacturing) device, an NC (Numerical Control) milling cutter, a machining center, or the like.
[0045] With the above configuration, the manufacturing system 1 can generate restorative prosthetic information suitable for the person H to be imaged, compared to when the gingiva information is not used. Furthermore, with this configuration, the manufacturing system 1 can manufacture the restorative prosthetic without involving the person H to be imaged in the processes related to the manufacture of the restorative prosthetic, other than the imaging by the tomography device 10. This means that the manufacturing system 1 can reduce at least a part of the consultation time, medical fees, physical burden, etc. of the person to be imaged. Furthermore, with this configuration, the manufacturing system 1 can repeatedly manufacture the same restorative prosthetic. As a result, the manufacturing system 1 can easily manufacture a spare restorative prosthetic, remanufacture a restorative prosthetic in case of damage, etc. Furthermore, the manufacturing system 1 can edit the STL data, such as correcting and modifying, in response to the accepted operation. As a result, the manufacturing system 1 can manufacture a restorative prosthetic in a shape that does not come into contact with a part of the gingiva of the person H to be imaged where the nerve is exposed. Furthermore, in the manufacture of the restorative prosthetic by the manufacturing system 1, there is no need for a dentist to perform a procedure in the oral cavity. Therefore, even if an infectious disease is prevalent, the manufacturing system 1 can ensure the safety of medical personnel such as dentists. Furthermore, when the manufacturing device 30 is a 3D printer, the manufacturing system 1 can reduce wasteful materials (e.g., cutting waste, etc.) in the manufacture of a restorative prosthesis.
[0046] <Hardware configuration of information processing device> The hardware configuration of the information processing device 20 will be described below with reference to Fig. 2. Fig. 2 is a diagram showing an example of the hardware configuration of the information processing device 20.
[0047] The information processing device 20 includes, for example, a CPU 21, a storage unit 22, an input receiving unit 23, a communication unit 24, and a display unit 25. These components are connected to each other via a bus so that they can communicate with each other. The information processing device 20 also communicates with each of the tomographic imaging device 10 and the manufacturing device 30 via the communication unit 24.
[0048] The CPU 21 executes various programs stored in the storage unit 22. Note that the information processing device 20 may be configured to include, instead of the CPU 21, another processor such as an FPGA (Field Programmable Gate Array).
[0049] The storage unit 22 includes, for example, a hard disk drive (HDD), a solid state drive (SSD), an electrically erasable programmable read only memory (EEPROM), a read only memory (ROM), a random access memory (RAM), etc. Note that the storage unit 22 may be an external storage device connected via a digital input / output port such as a USB, instead of being built into the information processing device 20. The storage unit 22 stores various information, various images, and various programs processed by the information processing device 20.
[0050] The input receiving unit 23 is, for example, an input device such as a keyboard, a mouse, a touch pad, etc. Note that the input receiving unit 23 may be a touch panel that is integrated with a display.
[0051] The communication unit 24 includes, for example, a digital input / output port such as a USB, an Ethernet (registered trademark) port, and the like.
[0052] The display unit 25 is, for example, a display device including a liquid crystal display panel, an organic EL (ElectroLuminescence) display panel, or the like.
[0053] <Functional configuration of information processing device> The functional configuration of the information processing device 20 will be described below with reference to Fig. 3. Fig. 3 is a diagram showing an example of the functional configuration of the information processing device 20.
[0054] The information processing device 20 includes a storage unit 22, an input receiving unit 23, a communication unit 24, a display unit 25, and a control unit 26.
[0055] The control unit 26 controls the entire information processing device 20. The control unit 26 includes an information acquisition unit 261, a display control unit 262, a first device control unit 263, a second device control unit 264, and a data editing unit 265. These functional units included in the control unit 26 are realized, for example, by the CPU 21 executing various programs stored in the storage unit 22. In addition, some or all of the functional units may be hardware functional units such as LSI (Large Scale Integration) and ASIC (Application Specific Integrated Circuit).
[0056] The information acquisition unit 261 acquires various kinds of information. For example, the information acquisition unit 261 acquires imaged person information from the tomographic imaging apparatus 10. Also, for example, the information acquisition unit 261 acquires various kinds of information accepted from the user via the input acceptance unit 23.
[0057] The display control unit 262 generates various images in response to the received operation. The display control unit 262 causes the display unit 25 to display the generated images.
[0058] The first device control unit 263 controls the tomographic imaging apparatus 10 .
[0059] The second apparatus control section 264 controls the manufacturing apparatus 30 .
[0060] The data editing unit 265 edits various types of data. For example, the data editing unit 265 converts the imaged person information acquired by the information acquisition unit 261 as DICOM data into STL data. Also, for example, the data editing unit 265 edits the STL data in response to a received operation.
[0061] <Processing related to the manufacture of restorative prostheses among the processing performed by the information processing device in the manufacturing system> Hereinafter, with reference to FIG. 4, a process related to the manufacture of a restorative prosthesis among the processes performed by the information processing device 20 in the manufacturing system 1 will be described. FIG. 4 is a diagram showing an example of the flow of a process related to the manufacture of a restorative prosthesis among the processes performed by the information processing device 20 in the manufacturing system 1. In addition, hereinafter, as an example, a case where the information processing device 20 accepts an operation to start the process at a timing before the process of step S110 shown in FIG. 4 is performed will be described. In addition, hereinafter, as an example, a case where the imaged person H is placed in a position and posture that can be imaged by the tomography imaging device 10 at that timing will be described. In addition, hereinafter, as an example, a case where the imaged person H has no teeth will be described. In this case, the restorative prosthesis indicated by the restorative prosthesis information generated by the information processing device 20 is a full denture. In addition, hereinafter, as an example, a case where the imaged person information does not include the above-mentioned gum information and skin information will be described.
[0062] The first device control unit 263 controls the tomographic imaging apparatus 10 to cause the tomographic imaging apparatus 10 to capture a tomographic image of the subject H (step S110). As a result, the tomographic imaging apparatus 10 generates DICOM data as subject information, and outputs the generated subject information to the information processing device 20.
[0063] Next, the information acquisition unit 261 acquires the imaged person information output from the tomographic imaging apparatus 10 in step S110 (step S120).
[0064] Next, the data editing unit 265 converts the imaged person information acquired as DICOM data by the information acquisition unit 261 in step S120 into STL data (step S130). In this example, the imaged person information includes jawbone part shape information, but does not include gum information or skin information. In this case, the STL data converted in step S130 is STL data showing the shape of the jawbone part of the imaged person H. In the following, for convenience of explanation, the STL data converted in step S130 will be referred to as jawbone part shape STL data. Here, FIG. 5 is a diagram showing an example of jawbone part shape STL data. STL data D1 shown in FIG. 5 is an example of jawbone part shape STL data. As shown in FIG. 5, the STL data D1 shows the shape of the jawbone part of the imaged person H.
[0065] Next, the display control unit 262 causes the display unit 25 to display, as an edited image, an image including the jaw part shape STL data after conversion by the data editing unit 265 in step S130 (step S140). Here, the edited image may be any image as long as it includes a GUI that allows editing of the jaw part shape STL data.
[0066] Next, the data editing unit 265 waits until it receives an operation via the editing image displayed on the display unit 25 (step S150). The operation includes, for example, an operation of editing the jawbone part shape STL data, an operation of inputting parameters required for the editing, an operation of combining the gingiva shape STL data with the jawbone part shape STL data, an operation of combining the restorative prosthetic shape STL data with the jawbone part shape STL data obtained by combining the gingiva shape STL data, an operation of completing the editing, and the like, but is not limited thereto. Here, the gingiva shape STL data is STL data indicating the shape of a person's gingiva, and is 3D template image data previously stored in the storage unit 22. Moreover, the restorative prosthetic shape STL data is STL data indicating the shape of a restorative prosthetic (in this example, a full denture) to be attached to the gingiva of the photographed person H, and is 3D template image data previously stored in the storage unit 22.
[0067] When the data editing unit 265 determines that an operation has been received in step S150 (step S150-YES), it performs processing according to the received operation (step S160). For example, when an operation to edit the jawbone part shape STL data is received in step S150, the data editing unit 265 performs editing on the jawbone part shape STL data according to the received operation. For example, the editing includes a process to fill in missing parts of the jawbone part shape STL data, a process to smooth the surface of the shape indicated by the jawbone part shape STL data, and the like. Also, for example, when an operation to input parameters required for the editing is received, the data editing unit 265 stores the received parameters in the storage unit 22. The parameters are, for example, parameters indicating the thickness of the gingiva of the subject H (there is little individual difference in the thickness of the gingiva of a person, so there is no practical problem even if an average value is used), but are not limited thereto. Also, for example, when an operation to combine the gum shape STL data with the jawbone part shape STL data is received, the data editing unit 265 combines the gum shape STL data with the jawbone part shape STL data. The data editing unit 265 enlarges, reduces, deforms, etc. the gum shape STL data according to the shape indicated by the jawbone part shape STL data and the thickness of the gums received as the above-mentioned parameters, and changes the shape indicated by the gum shape STL data to a shape of the gums that matches the shape indicated by the jawbone part shape STL data (for example, gums with a thickness specified by the above-mentioned parameters and that fit the shape of the jawbone part of the subject H). Then, the data editing unit 265 combines the changed gum shape STL data with the jawbone part shape STL data. In the following, for convenience of explanation, the jawbone part shape STL data after being combined with the gum shape STL data will be referred to as first STL data. Also, for example, when an operation to combine the first STL data with the restorative prosthetic shape STL data is received, the data editing unit 265 combines the first STL data with the restorative prosthetic STL data. The data editing unit 265 enlarges, reduces, transforms, etc. the restorative prosthetic STL data according to the shape of the gingiva indicated by the first STL data, and changes the shape indicated by the restorative prosthetic shape STL data to a shape of the restorative prosthetic that matches the shape of the gingiva indicated by the first STL data.Then, the data editing unit 265 combines the modified restorative prosthetic shape STL data with the first STL data. In the following, for convenience of explanation, the first STL data after the restoration prosthetic shape STL data is combined will be referred to as the second STL data. Also, for example, when the data editing unit 265 receives an operation to complete the editing, the display control unit 262 deletes the edited image from the display unit 25. Here, when the data editing unit 265 performs editing on the STL data included in the edited image, the display control unit 262 reflects the editing performed on the STL data in the STL data included in the edited image. Therefore, the user of the information processing device 20 can easily edit the STL data while viewing the edited image. The data editing unit 265 may enlarge, reduce, or deform the two above-mentioned three-dimensional template image data based on the received operation. Also, the three-dimensional template image data on the gums is an example of gum information indicating the gums of the imaged person, and is an example of information indicating the gums of a predetermined thickness. Here, FIG. 6 is a diagram showing an example of the first STL data. The STL data D2 shown in FIG. 6 shows an example of the first STL data. Moreover, the STL data D3 shown in FIG. 6 is an example of the gum shape STL data. That is, the STL data D2 which is an example of the first STL data is STL data obtained by combining the STL data D1 which is an example of the jawbone part shape STL data with the STL data D3 which is an example of the gum shape STL data, as shown in FIG. 6. As described above, the data editing unit 265 enlarges, reduces, deforms, etc. the gum shape STL data according to the shape indicated by the jawbone part shape STL data and the thickness of the gums accepted as a parameter, and changes the shape indicated by the gum shape STL data to a shape of the gums that matches the shape indicated by the jawbone part shape STL data. The STL data D3 shown in FIG. 6 is an example of the gum shape STL data after the shape has been changed by the data editing unit 265 in this way. In the example shown in FIG. 6, the STL data D3 is combined with STL data indicating the shape of the teeth of the photographed person H, but the STL data does not necessarily have to be combined in the process of step S160.The first STL data may be STL data in which STL data D1, which is an example of jawbone part shape STL data, is combined with STL data D4, which is an example of gum shape STL data showing the shape of the lower gums of the subject H, as shown in Fig. 7. Fig. 7 is a diagram showing an example of the first STL data including gum shape STL data showing the shape of the lower gums of the subject H. The first STL data may be STL data in which STL data D1, which is an example of jawbone part shape STL data, is combined with STL data D5, which is an example of gum shape STL data showing the shape of the upper gums of the subject H, as shown in Fig. 8. Fig. 8 is a diagram showing an example of the first STL data including gum shape STL data showing the shape of the upper gums of the subject H.
[0068] Next, the data editing unit 265 determines whether or not the acceptance of the operation via the edited image displayed on the display unit 25 has ended (step S170). For example, in step S160, when the display control unit 262 deletes the edited image from the display unit 25, the data editing unit 265 determines that the acceptance of the operation has ended. Note that the data editing unit 265 may be configured to determine that the acceptance of the operation via the edited image displayed on the display unit 25 has ended when other conditions are satisfied. On the other hand, in step S160, when the display control unit 262 has not deleted the edited image from the display unit 25, the data editing unit 265 determines that the acceptance of the operation has not ended. Note that the data editing unit 265 may be configured to determine that the acceptance of the operation via the edited image displayed on the display unit 25 has not ended when other conditions are satisfied.
[0069] If the data editing unit 265 determines that the acceptance of operations via the editing image displayed on the display unit 25 has not been completed (step S170-NO), it transitions to step S150 and waits again until an operation is accepted via the editing image displayed on the display unit 25.
[0070] On the other hand, if the data editing unit 265 determines that the acceptance of operations via the editing image displayed on the display unit 25 has ended (step S170-YES), it stores the second STL data edited in step S160 in the memory unit 22 (step S180).
[0071] Next, the second device control unit 264 reads out from the memory unit 22 the second STL data stored in the memory unit 22 in step S180, and outputs the restorative prosthetic shape STL data among the STL data contained in the read second STL data to the manufacturing device 30 as restorative prosthetic information regarding the restorative prosthetic to be attached to the gums of the subject (step S190).
[0072] Next, the second device control section 264 controls the manufacturing device 30 to start manufacturing a restorative prosthesis having a shape indicated by the restorative prosthesis information based on the restorative prosthesis information output in step S190 (step S200).
[0073] Next, the second device control unit 264 waits until the manufacture of the restorative prosthesis started in step S200 is completed (step S210). Here, the second device control unit 264 determines that the manufacture of the restorative prosthesis started in step S200 is completed when, for example, it acquires information indicating that the manufacture of the restorative prosthesis is completed from the manufacturing device 30. Note that the second device control unit 264 may be configured to determine that the manufacture of the restorative prosthesis started in step S200 is completed when other conditions are satisfied.
[0074] When it is determined that the manufacturing of the restorative prosthesis started in step S200 has been completed (step S210-YES), the second device control section 264 ends the processing of the flowchart shown in FIG.
[0075] As described above, the information processing device 20 outputs restorative prosthetic information on restorative prosthetics (in this example, complete dentures) to be attached to the gums of the subject H based on jawbone part shape information indicating the shape of the jawbone part included in the subject information on the subject H outputted as subject information from the tomography imaging device 10 that captures tomographic images of the jawbone part, including the jawbone, among the parts of the subject H, by a predetermined method, and gingiva information indicating the gums of the subject H according to the shape indicated by the jawbone part shape information. This allows the information processing device 20 to generate restorative prosthetic information suitable for the subject H. In other words, the manufacturing system 1 (or the information processing system S) can generate restorative prosthetic information suitable for the subject H.
[0076] As described above, the photographed person information may include gingiva information. In this case, the data editing unit 265 can directly convert the photographed person information, which is DICOM data, into the first STL data without receiving an operation from the user and without going through conversion into jawbone part shape STL data. Here, FIG. 9 is a diagram showing an example of an image based on DICOM data including gingiva information. Image P1 shown in FIG. 9 shows an example of an image based on the DICOM data. Among the areas of image P1, the area filled with a thick line in FIG. 9 is an area showing the gingiva of the photographed person H. As shown in FIG. 9, the photographed person information may be generated as DICOM data including gingiva information.
[0077] Furthermore, when the photographed person information includes gingiva information, the information processing device 20 may be configured to generate gingiva shape STL data based on the gingiva information included in the photographed person information. In this case, the information processing device 20 converts the photographed person information into gingiva shape STL data in the process of step S130. Then, the information processing device 20 displays an image including the gingiva shape STL data as an edited image on the display unit 25 in the process of step S140. Furthermore, when the information processing device 20 receives an operation to combine the gingiva shape STL data with the restorative prosthetic shape STL data in the processes of steps S150 to S170, the data editing unit 265 combines the gingiva shape STL data with the restorative prosthetic STL data. Even in this case, the information processing device 20 can generate restorative prosthetic information suitable for the photographed person H.
[0078] The imaged person information may further include skin information indicating the skin of the jawbone region of the imaged person. In this case, when converting the imaged person information, which is DICOM data, into jawbone region shape STL data, the data editing unit 265 converts the imaged person information into the jawbone region shape STL data as 3D image data indicating the shape of the skin together with the shape of the jawbone region of the imaged person H.
[0079] Furthermore, when the imaged person H has one or more teeth, that is, when the imaged person information includes dentition information, the data editing unit 265 converts the imaged person information, which is DICOM data, into jawbone part shape STL data as 3D image data showing the shape of the imaged person H's dentition as well as the shape of the jawbone part of the imaged person H. Then, in response to the accepted operation, the data editing unit 265 combines STL data showing the shape of a partial denture, a silver filling, etc. with the jawbone part shape STL data as restorative prosthesis shape STL data. As a result, the information processing device 20 can manufacture restorative prostheses for not only full dentures but also partial dentures, silver fillings, etc., without involving the imaged person H in processes related to the manufacture of restorative prostheses other than imaging by the tomography device 10.
[0080] As described above, the information processing device according to this embodiment (information processing device 20 in the above-described example) outputs restorative prosthetic information on restorative prosthetics (full dentures, partial dentures, and silver fillings in the above-described example) to be attached to at least one of the teeth and gums of the imaged person based on jawbone part shape information indicating the shape of the jawbone part included in the imaged person information on the imaged person outputted as imaged person information from a tomography device (tomography device 10 in the above-described example) that captures a tomography image of the jawbone part including the jawbone among the parts of the imaged person (imaged person H in the above-described example) by a predetermined method (CT image reconstruction method in the above-described example). This allows the information processing device to generate restorative prosthetic information suitable for the imaged person.
[0081] Furthermore, the information processing device may be configured such that the gum information is information included in the photographed person information, or information indicating a predetermined thickness of the gums.
[0082] In addition, the information processing device may be configured so that the imaged subject information includes dentition information indicating the dentition of the imaged subject if the imaged subject has one or more teeth, and does not include dentition information if the imaged subject has no teeth.
[0083] In addition, the information processing device may be configured such that the restorative prosthesis is a complete denture attached to the imaged person, and the restorative prosthesis information is three-dimensional image data indicating the complete denture.
[0084] Furthermore, in the information processing device, a configuration may be used in which the three-dimensional image data is STL data.
[0085] The information processing device may be configured such that the imaged person information further includes skin information indicating the skin in the jawbone area.
[0086] Moreover, in the information processing device, a configuration may be used in which the predetermined method is a CT image reconstruction method, and the tomographic imaging device is a CT device.
[0087] Furthermore, the information processing device may be configured to output restoration prosthetic information based on the photographed person information, the three-dimensional template image data of the restoration prosthetic, and the accepted operation.
[0088] The manufacturing device according to this embodiment (the manufacturing device 30 in the above-described example) is a manufacturing device that manufactures a restorative prosthesis based on the restorative prosthesis information output from the information processing device described above. This allows the manufacturing device to generate restorative prosthesis information suitable for the imaged patient.
[0089] Moreover, the information processing system according to this embodiment (information processing system S in the example described above) is an information processing system including a tomographic imaging device and an information processing device, in which the tomographic imaging device captures a tomographic image of a jawbone part including the jawbone among parts of the subject by a predetermined method, and the information processing device outputs restorative prosthetic information related to restorative prosthetics to be attached to at least one of the teeth and gums of the subject based on jawbone part shape information indicating the shape of the jawbone part included in the subject information on the subject outputted as subject information from the tomographic imaging device, and gingiva information indicating the gingiva of the subject according to the shape indicated by the jawbone part shape information. This allows the information processing system S to generate restorative prosthetic information suitable for the subject.

In this way, the manufacturing system can generate restorative prosthetic information suitable for the imaged person.
[0091] Moreover, the manufacturing system according to this embodiment (the manufacturing system 1 in the example described above) is a manufacturing system including a tomographic imaging device, an information processing device, and a manufacturing device, in which the tomographic imaging device captures a tomographic image of a jawbone part including the jawbone among parts of the subject by a predetermined method, the information processing device outputs restorative prosthetic information regarding restorative prosthetics to be attached to at least one of the teeth and the gingiva of the subject based on jawbone part shape information indicating the shape of the jawbone part included in the subject information on the subject outputted as the subject information from the tomographic imaging device and gingiva information indicating the gingiva of the subject according to the shape indicated by the jawbone part shape information, and the manufacturing device manufactures restorative prosthetics based on the restorative prosthetic information outputted from the information processing device. This allows the manufacturing system to generate restorative prosthetic information suitable for the subject.
