Description

Implant placement guide production system, method and computer program {SYSTEM, METHOD AND COMPUTER PROGRAM FOR PRODUCING IMPLANT PLACING GUIDE}

The present invention relates to a system, a method and a computer program for implant placement guide production, and more particularly, to a system, a method and a computer program for manufacturing an implant fixture guide using a ready-made guide tray.

Dental implantation involves placing the implant fixture in the alveolar bone. In order to properly implant the implant fixture in the alveolar bone, a guide mechanism commonly called a guide stent or a surgical guide is used.

Guide stents currently used in the treatment field is Korean Patent Registration No. 10-1473192 (prior document 1, the name of the invention: manufacturing method of the implant guide stent, published date: December 16, 2014), Korea Patent Registration No. 10-1554157 (Previous Document 2, Reference Marker for Oral Internal Attachment and Guide Stent Manufacturing Method for Implant Procedures Using the Same, Announcement Date: 2015.09.21.) And the like are prepared by a method similar to that disclosed.

[FIG. 1] illustrating a guide stent manufacturing method described in Prior Art 2 is illustrated in FIG. 1 of the present specification. Referring to FIG. 1, a conventional guide stent manufacturing method will be briefly described as follows. First, in the dentist, the operator acquires a three-dimensional image of the inside of the oral cavity (oral periodontal tissue) through the CT scan of the subject, and obtains a three-dimensional external shape image corresponding to the three-dimensional image through an oral scan (s1). . The oral scan is performed by the operator inserting the scanner into the subject's oral cavity, and the image is often distorted because the scanner must be scanned along the inside of the oral cavity.However, CT scan can only check the hard tissue in the oral cavity. It is necessary to check the crown shape of the subject's gums or teeth.

The obtained intraoral 3D image and the external shape image of the operator are image-aligned based on the feature or marker of the tooth included in each image, and the 3D procedure guide image is generated through the image registration (s2). The operator establishes an implant treatment plan using the 3D surgical guide image (s3) and manufactures a stent body having guide holes formed according to the surgical guide image (s4).

In general, the first step (s1) to the last step (s4) takes about 2 to 3 days, because each step is not made by a single subject. In particular, the manufacture of the guide stent is performed by the guide stent manufacturer with precision processing equipment, rather than by the implant operator (dentist), so the guide stent manufacturer establishes a three-dimensional procedure guide image or implant procedure plan to guide the stent. It takes a lot of time to manufacture and the operator to receive the guide stent delivery. Even if the dentist had equipment such as a 3D printer, it took a lot of time for 3D printing.

In addition, since the external shape image obtained through the oral scan is inevitable distortion, there was a problem that the guide stent made through image registration does not exactly fit the oral structure of the subject.

The present invention is to solve the above-described problems, and an object of the present invention is to significantly improve the convenience of the subject by significantly shortening the guide stent manufacturing time.

In addition, the present invention provides a system for producing an implant placement guide using a ready-made tray, so that each performing entity participating in the implant placement guide can be easily generated and profit distribution can be made in a different manner. The purpose.

It is another object of the present invention to provide a guide fabrication system, method and computer program which can facilitate the design and modification of implant placement guides.

The present invention also provides a method and system for implant placement guide that can provide a guide that fits perfectly inside the mouth of the subject without error by allowing the implant placement guide to be produced without matching the internal oral 3D image and the external shape image. To provide for other purposes.

In order to achieve the above object, the present invention provides a method for manufacturing an implant placement guide in a design review terminal, the method comprising: receiving a review request signal from a management server; Receiving implant design information generated by a planner terminal from a management server, receiving a review result of the implant design information from a user, and transmitting the review result to the management server, wherein the implant design information is included. The guide tray filled with the impression material is generated based on the three-dimensional image in the oral cavity taken by the CT taken in the mouth of the subject, the guide tray is one or more for matching the image of the guide tray and the three-dimensional image The marker includes the marker Characterized in that one tooth shape is impressive.

According to the present invention as described above, the implantation guide production time is significantly shortened, there is an effect that the convenience of the subject significantly improved.

In addition, according to the present invention, each performing agent who participates in the implant placement guide production can easily generate revenue, and the profit distribution can be made in a fair manner.

In addition, the present invention facilitates the design and modification of the implant placement guide.

In addition, according to the present invention, it is possible to produce an implant placement guide without matching the intraoral 3D image and the external shape image, thereby providing the guide with a guide that fits perfectly inside the oral cavity of the subject without error.

And unless specified otherwise, reference to the singular may include one or more, and reference to the singular may also include the plural expression.

2 is a view showing an implant placement guide manufacturing system according to an embodiment of the present invention.

Referring to Figure 2, the implant placement guide production system according to an embodiment of the present invention dental terminal 400, implant placement guide production management server 100 (hereinafter referred to as "management server 100"), planner The terminal 200 may further include a terminal for design review 300 and an implant placement guide processing machine 500.

The dental terminal 400 is a terminal provided in a dentist, and may be an electronic device such as a PC, a tablet, a smartphone, etc., in which an application program for executing an implant placement guide manufacturing method according to an embodiment of the present invention is installed. Furthermore, when the implant placement guide manufacturing method according to an embodiment of the present invention is implemented in a web, it may be an electronic device accessible to the web.

The dental terminal 400 transmits a 3D image taken in a CT state while the guide tray filled with the impression material is inserted into the mouth of the subject to the management server 100 and receives a file for implant placement guide processing from the management server 100. do.

The guide tray of the present invention may be similar to the impression tray (Impression Tray) for shaping the teeth, but is a ready-made guide tray in which the tooth shape of the subject is impressed, i) the image of the guide tray and the three-dimensional image The difference is that it includes a marker used to mate, ii) used to identify the type of guide tray, and iii) used to identify whether sleeve mounting is required.

Guide tray according to an embodiment of the present invention may include one or more markers for performing the above-described functions, preferably three or more markers may be formed. The marker may be a radiopaque material, and thus may be displayed on a three-dimensional image obtained through CT imaging. The marker may be formed on the flat side of the body that receives the impression material from the guide tray, in which case the marker identifies the guide tray in the three-dimensional image and matches the three-dimensional image with the image of the guide tray. Becomes In addition, the marker may be a reference for designing the position, depth, direction, etc. of the implant fixture.

The operator fills the impression material in the guide tray, inserts the tray into the mouth of the subject, and performs a CT scan with the tray inserted in the region to be implanted. The three-dimensional image of the inside of the oral cavity obtained through CT imaging is internal tissue information such as the crown (upper tooth appearing outside the gum), the root (the lower part of the tooth hidden inside the gum as part of the alveolar bone) and alveolar bone inside the oral cavity. It includes, and includes a marker image of the guide tray. The three-dimensional image does not accurately provide information about the gums, and conventionally, in order to solve such a problem, a three-dimensional external shape image was obtained through an oral scan, and the three-dimensional image and the external shape image inside the oral cavity were image matched.

However, according to an embodiment of the present invention, since the oral scan is unnecessary, it is sufficient for the dental terminal 400 to transmit the CT-photographed 3D image to the management server. Therefore, the process of acquiring the oral state information of the subject for implantation is significantly shortened, which leads to the effect of reducing the procedure time and cost.

The management server 100 is a computing device for managing the implant placement guide production according to an embodiment of the present invention, may be a web server or a cloud server. The management server 100 receives a 3D image from the dental terminal, transmits a design request signal to one or more registered planner terminals, and receives the implant design information from the planner terminal that accepts the design request signal, and uses the implant using the same. You can create a file for the placement guide machining. The design request signal may be a message (SMS) sent through a text and may be a push notification transmitted through an application program installed in the planner terminal 200.

In the present specification, the implant design information is the information that the implant procedure plan is established on the three-dimensional image, the size of the fixture, the type of the fixture, the position of the fixation implantation depth, the implantation depth, whether bone graft, maxillary sinus transplantation It may include at least one of, gum implantation, the order of use tools. According to the present invention, the implant design information may be generated by a user who uses each terminal in the planar terminal 200, the design review terminal 300, or the dental terminal 400, and the implant design information of the present invention is an implant It can be created, duplicated, transmitted and stored in the form of design information files (STL files and / or PDF files).

The operation of the management server 100 will be described later in detail with reference to FIG. 3.

Implant placement guide production system 10 according to an embodiment of the present invention may include a planner terminal 200. The planar terminal 200 may be a terminal of a user who has been previously certified as having an implant design qualification, and may be a terminal of a user who is certified as having both an implant design qualification and a pseudo qualification. The planner terminal 200 transmits the design request signal to the management server when the design request signal is received from the management server, and receives the implant design information corresponding to the 3D image from the management server to the management server. Can transmit

The implant placement guide production system 10 of the present invention may further include a terminal for design review 300. The design review terminal 300 is a terminal of a user authenticated as having a pseudo qualification, and when the user of the planner terminal 200 is a terminal of a user certified as having both implant design qualification and pseudo qualification, the system 10 ) May not be included. When the design review terminal 300 receives the review request signal from the management server, it transmits whether to accept the review request signal to the management server, and when the implant design information is received from the management server, the corresponding review result is received and managed. You can send it to the server.

The transmission of the accept signal may be performed by a user touching or clicking a link of a message (SMS) displayed through the terminal 200 or 300, or touching an accept button or a link displayed on a web page provided through the web server 100. The act of clicking may be performed by touching or clicking an acceptance button of an application program installed in the terminal 200 or 300, and the method of transmitting the acceptance to the server 100 is not limited thereto.

The implant placement guide manufacturing system 10 of the present invention may further include an implant placement guide processing machine 500 (hereinafter, referred to as a “processing machine 500” for convenience of description). The processing machine 500 according to an embodiment of the present invention is provided in a dentist that transmits a 3D image, and receives a file for implant placement guide processing from a management server or a dental terminal, using a guide tray for implant placement guide processing. The position of the jig and the guide hole corresponding to the type of the identification may be identified, and the guide hole may be drilled in the guide tray using the identified jig. The file for implant placement guide machining includes a guide tray image showing the position of the guide hole. The machining file may or may not include implant design information on the guide tray image. Furthermore, the guide hole may or may not be mounted with a metal sleeve. When mounted, the processing file may include information about the position of the sleeve and an area deleted due to the sleeve mounting.

That is, when the operator is provided with the processing machine 500, the operator (dental terminal) obtains the intra-oral three-dimensional image of the subject and transmits it to the management server, the implant placement guide within a few minutes to a long time to 1-2 hours The processing file can be received, and the implant placement guide processing file is transmitted to the processing machine 500-and even if the implant placement guide processing file is directly transmitted to the processing machine 500, it is unnecessary. -When the guide tray obtained by the impression of the operator is mounted on the machine 500, the machine 500 only needs to drill the guide hole by automatically identifying the position of the guide tray and the guide hole and the required jig on the previously generated guide tray. The implant placement guide can be obtained within minutes. In addition, the implant placement guide according to an embodiment of the present invention is filled with the impression material and inserted into the dentition and gums of the subject to obtain the impression and hardened the impression material, characterized in that the tooth shape of the subject is raised, Therefore, because the subject's teeth and gums are seated without error. Therefore, not only the implant procedure is very easy, but there is no problem that the implant placement guide does not fit inside the mouth of the subject, so that modification is unnecessary and the satisfaction of the subject is increased.

In an embodiment of the present invention, the implant placement guide machining file may be recognized by the processing machine 500 (or a milling machine) and may include an NC file recognizable by a CAM program which is a machine driving program.

Hereinafter, an operation method of the implant placement guide manufacturing system 100 according to various embodiments of the present disclosure will be described with reference to the drawings.

Example 1: dental terminal, Planner  When system is composed of terminal and management server

3 is an example of a case where a user of the planar terminal possesses both an implant design qualification and a pseudo qualification. Since the final confirmation for the implant procedure should be made by a doctor, it is assumed in this embodiment that the user of the planar terminal possesses a doctor's qualification.

Referring to FIG. 4, the dental terminal acquires a 3D image obtained through CT imaging in a state in which the guide tray of the present invention is inserted into the oral cavity (S100). This means that the dental terminal receives a 3D image obtained through CT imaging from the photographing apparatus. Next, the dental terminal may transmit the 3D image to the management server. Transmission to the management server involves uploading a three-dimensional image. The three-dimensional image transmitted from the dental terminal to the management server includes identification information of the dental terminal (dental code, dental name, operator name, etc.) and subject information (such as the name, age, gender, and other personal information required for the implant operation) of the dental terminal. May be included.

When the management server receives the 3D image (S200), that is, when the 3D image and other information are uploaded, the management server may transmit a design request signal to one or more registered planner terminals (S300). The transmission of the design request signal may be implemented by informing the planner terminal of the upload fact as described above.

The planar terminal is a terminal used by a planner having an implant design qualification and a pseudo qualification, and may be a terminal device in which an application program for supporting an implant placement guide manufacturing method according to an embodiment of the present invention is installed. The planners may register planner information with the management server in advance through the application or the web, and when registering, the planner terminal user information (the name of the planner, the qualifications held by the planner, the history of the planner activity, etc.) may be registered with the management server. Can transmit The management server may assign a different status for each planner after checking the qualification held by the planner. For example, planners with only implant design qualifications are given level A, and planners with both implant design qualifications and physician qualifications are given level S. In other words, planners can be classified into one or more groups according to the technology they possess, and the criteria may vary depending on the manager's setting.

As another example, the management server may classify the planner according to the planner's retention history, and classify the planner according to the feedback (star rating or review) of the dental terminal.

The planner can connect to the management server regardless of the terminal using the ID and password registered in advance, and can designate a desired time to receive the design request signal, and whether to receive or reject the design request signal. Can be set.

When the planner receives the design request signal in operation 300, the planner may determine whether to accept the signal and input the received signal to the terminal. When the planner inputs a selection input for accepting the design request signal to the planner terminal, the planner terminal may transmit a signal indicating that the design request signal has been accepted to the management server (S400).

When the management server receives the acceptance of the design request signal, the management server may transmit a 3D image to the planner terminal that accepts the design request signal (S500). Acceptance of the design request signal and transmission of the corresponding 3D image means the completion of a contract between the management server and the planner. In step 500, the planner accesses the management server using a planner terminal to access a 3D image file (CT file, dicom file) can be implemented through the operation of downloading.

If the reception of the design request signal from the plurality of planar terminals is received, the management server may select one or a plurality of planar terminals according to preset criteria. For example, the management server may select the planar terminal based on the order in which the signal for accepting the design request signal arrives at the management server, and the planar terminal having the least or most implant design history is selected using the registered planar information. You can also choose. The criteria for selecting a planner terminal may vary according to the manager setting, and whether to select one planner terminal or a plurality of planner terminals may also be changed by the manager setting.

The planar terminal receiving the 3D image generates the implant design information based on the 3D image (S600). Implant design information is the information that the implant planning is established on the three-dimensional image. The size of the fixture, the type of the fixture, the position of the fixture, the depth of the implant placement, the bone graft, the maxillary sinus graft, the gum implantation It may include at least one of the use tool sequence. Information such as the size of the fixed body and the type of the fixed body may be input to the planner terminal through input devices such as a touch screen, a keyboard, a mouse, and a touch pad provided or connected to the planar terminal, and the planar terminal may use the input information. Implant design information can be generated. The implant design information of the present invention may be generated, duplicated, transmitted, and stored in the form of an implant design information file (STL file and / or PDF file).

The planner terminal transmits the generated implant design information to the management server (S700). The transmission of the implant design information to the management server includes the operation of the planar terminal uploading the implant design information (STL file and / or PDF file) to a web server or a cloud server corresponding to the management server.

Although not shown in the figure, the management server may check the classification information of the planner terminal that transmitted the implant design information to the management server. When it is confirmed that the planar terminal is a terminal of the planner having both the implant design qualification and the pseudo qualification, the management server may generate the implant placement guide processing file using the implant design information (S800).

Operation 800 may be an operation of converting the implant design information into a file in a format recognizable by the processor. For example, in operation 800, the management server 100 may convert the implant design information into an NC file that can be recognized by the processor 500. The implant design information may be a file (eg CAD file, STL (Stereo Lithography) file) in a format supported by the web or application provided by the management server, and the implant design information file may be used for processing implant placement guides (eg NC-NC). File) may be a unique permission of the management server. The management server may generate a file for implant placement guide processing using a CAM program running only on the web or the cloud. In another embodiment, the implant design information may be encrypted when the implant design information is generated so that the processing machine is converted into a file in a processable form only by the management server. Alternatively, the implant design information may be a file that can be generated only by a web or an application program provided by the management server of the present invention. Furthermore, the implant placement guide processing file according to an embodiment of the present invention may be a file having a format executable only by a predetermined machine.

The conversion of the implant design information into a file for implant placement guide machining as a unique authority of the management server is for building a profit model based on the generation (or output) of the file for implant placement guide machining.

As an example, when the implant placement guide processing file is generated (S800), the management server may check whether payment information (card information or account information, etc.) of the dentist who requested the guide processing file is registered (S830). If the dental card information or account information is registered, the dental office notifies the generation of the guide file for processing (S850), and transmits the file for processing (S900). Operation 900 includes a method in which the dental terminal accesses the web server 100 and downloads a file. After the file is transferred, payment corresponding to the file transfer for processing may be paid using the payment information (S1000). Step 1000 may be performed before steps 850 and 900.

If it is determined in step 830 that the payment information of the dentist requesting the guide processing file is not registered in the management server 100, the management server 100 may block access to the server 100 of the dental terminal. For example, when the management server is a web server, it is possible to restrict the downloading of the guide processing file by not blocking or granting access to the web server of the dental terminal in which payment information is not registered.

In another embodiment, the management server transmits the implant placement guide processing file to the dental terminal or the processor (S900), and counts the number of times or the number of transmission of the implant placement guide processing file to claim the design cost to the dental terminal by that number of times. It may be (S1000). In another embodiment, the billing of the service amount may be made before the step 800 of generating the implant placement guide processing file or the step 900 of transferring the implant placement guide processing file, and the service amount corresponding to the billing from the dental terminal. Once deposited, it is also possible to perform step 800 or step 900.

When the service amount is received, the management server may transfer the remaining amount except for the predetermined fee to an account associated with the planner terminal 1 performing the implant design (S1100).

Example 2: dental terminal, Planner  When the system is composed of terminals, design review terminals, and management server

As shown in FIG. 2, an embodiment of a system configured with the dental terminal 400, the planar terminal 200, the design review terminal 300, and the management server 100 will be described with reference to FIG. 5. do. It is assumed that the planar terminal in the present embodiment is a terminal of a user who is authenticated as having only implant design qualification, and the terminal for design review is a terminal of a user who is certified as having pseudo qualification. Some steps omitted from FIG. 5 may refer to FIG. 4 (assuming that the planner terminal of FIG. 5 is planar terminal 1 of FIG. 4).

Implant design information generated by planners with only implant design qualifications needs to be verified by a user with pseudo-qualification. Therefore, if the planner terminal that accepts the design request signal in response to the design request signal in step 300 is a terminal of the planner certified as having only the implant design qualification, the management server is an implant generated as shown in steps 710 to 760 of FIG. Reviewing design information may be additionally performed.

Referring back to step 600, the management server may receive the implant design information from the planner terminal, and may transmit a review request signal to one or more registered design review terminals (S710). When the review request signal acceptance is transmitted from any one of the plurality of design review terminals that have received the review request signal (S720), the management server may transmit the implant design information to the design review terminal that has accepted the review request signal (S730). ). Steps 720 to 730 of selecting a design review terminal may be performed by a method similar to the embodiment described in steps 300 to 400 of FIG. 4. That is, the acceptance of the review request signal and the transmission of the implant design information may be understood to mean a contract between the management server and the design review terminal.

The design review terminal may transmit a review result to the management server (S740). The review results may include amendments and corrections to the implant design information, and may include confirmation comments that the implant design is in place. The management server checks the review result (S750), and if the review result includes the modified opinion, it may transmit the review result to the planner terminal (S753).

 The planner terminal receiving the review result including the modified opinion may modify the implant design information using the review result (S755). However, when the planner exists in the center having the management server, the management server internally reviews the review result. Implant design information can also be modified to reflect this. Or, using a machine learning framework learned using a large amount of data, the management server can modify the implant design information by reflecting the review opinion itself.

The modified implant design information is transmitted back to the management server (S760), and the management server passes it back to the terminal for design review (S765), so that the modification and review can be repeated until the correction is unnecessary.

If there is no correction as a result of the review, the management server may transmit the implant design information to the dental terminal (S770), and if the implant design information is approved from the dental terminal (S780), the implant placement guide processing file may be generated ( S800). For reference, steps 770 and 780 may be applied before executing step 800 in the embodiment of FIG. 4. That is, unnecessary file conversion can be minimized by generating a file for implant placement guide processing after receiving the implant design information from the dental terminal.

In the management server transmits the implant design information to the terminal for design review in step 730, by transmitting a remote access address and the implant design information to share and modify the three-dimensional image with the planner terminal, which generated the implant design information in real time, It is possible to enable real-time correction and confirmation between the planner terminal and the design review terminal without the steps 740 to 760. This embodiment is illustrated in FIG. 6. Referring to FIG. 6, the terminal for design review receiving the remote access address may remotely access the planner terminal (S735) and share and modify the implant design information (S737). In this case, there is no need to send and receive implant design information through the management server, and the modification and confirmation steps can be greatly shortened. Sharing and modification of implant design information through remote access may be made through the implant placement guide production application or the web according to the present invention, but may be made through other applications supporting remote access. An implant placement guide system illustrating this embodiment is further illustrated in FIG. 10.

6 illustrates an embodiment in which the dental terminal transmits a correction request (S790). When the dental terminal returns a correction request instead of returning an approval as shown in step 780 shown in FIG. 5 with respect to the implant design information received (S790), the management server transmits the correction request to the planner terminal (S793), The implant design information reflecting the correction request may be received and transmitted to the dental terminal (S797), and steps 793 to 797 may be repeated until the approval is received from the dental terminal.

5 to 6, as in the embodiment of FIG. 4, the service amount may be requested to the dental terminal before or after generating the implant placement guide processing file (S1000), and is set in an account associated with the planner terminal. The design fee may be remitted, and a predetermined design review fee may be remitted to an account associated with the design review terminal (S1100).

Embodiment 3: When the system is configured with a terminal and a management server

7 to 8 show that i) a whole procedure of implant surgery is performed in a center having a management server (in this case, the terminal is a computing device used in the center and the management server is a server provided in the center). Ii) a system having a dental office with a dental terminal and a center with a management server (in this case, the terminal is a dental terminal and the management server is a server provided in the center (web server or Cloud server).

The terminal may acquire a 3D image in the mouth of the subject through CT imaging in a state where the guide tray is inserted in the mouth (S10). Acquiring a three-dimensional image includes receiving a three-dimensional image from a CT imaging apparatus and receiving a three-dimensional image through a wired or wireless communication network.

The terminal may receive the implant design information from the terminal user (S20). For example, the terminal user may draw an implant procedure plan on a three-dimensional image through an input means connected to the terminal, and the size of the fixture, the type of fixture, the position of the fixture, the depth of implantation, and bone graft It may be noted whether it is a maxillary sinus graft, whether a gum is implanted, the order of the tools used, and the like. The implant design information may be generated in the STL file format as described above, and may include a STL file generated through the CAD program and a PDF file described about the procedure.

When the implant design information is input, the terminal may display the position of the guide hole on the image of the guide tray according to the implant design information. In addition, an implant placement guide machining file including an image of the guide tray in which the position of the guide hole is displayed may be generated (S30). The generation of the guide processing file may be performed by converting an STL file, which is an implant design information file, into an NC file. This file conversion can be done through a CAM program running on a web or cloud server. In this case, the terminal may upload the guide processing file to the web or cloud server, and convert the file by downloading the converted file when the file is converted. In another embodiment, the terminal may directly convert a file using a program installed in the terminal.

The generated implant placement guide processing file is transmitted to the processing machine (S40), and the processing machine processes the implant placement guide using the received processing file (S50). Processing of the implant placement guide can be performed by a simple operation of drilling a guide hole in the guide tray inserted into the oral cavity of the operator, and can greatly reduce the processing time without requiring 3D printing or sophisticated work.

Referring to step 50 in more detail with reference to Figure 9, the machine uses the number of markers of the guide tray (shown in the three-dimensional image), the shape of the markers, the angle formed by the plurality of markers, etc. included in the implant placement guide processing file The guide tray can be identified (S51). The guide trays come in various shapes and sizes corresponding to their use and the oral structure of the subject. The guide tray used in the present invention may have a unique identification code for each type and may have unique marker information. That is, the number, shape, angle, and shape of the plurality of markers appearing in the 3D image may be matched to each unique identification number.

When the processor of the present invention identifies the guide tray, the processor may search for a tray library and a jig library corresponding to the identified guide tray (S53). The tray library is a database including the appearance information and identification information of various guide trays, and the jig library is a database containing the appearance information and identification information of the machine jig suitable for use by each guide tray. The processor may drill the guide hole by using the jig matching the identified guide tray (S55).

After that, the processing history in the terminal may be transmitted to the management server (S60), the management server may record the processing history (S70), and accordingly charge the dental terminal (S80). However, step 60 to step 80 may be omitted as additional.

Finally, the method of manufacturing the implant placement guide according to an embodiment of the present invention will be described collectively.

The electronic device having a processor acquires a 3D image in the mouth of the subject through CT imaging while inserting the guide tray filled with the impression material into the mouth of the subject, and receives implant design information on the 3D image. Next, the electronic device aligns the image of the guide tray with the 3D image by using marker information of the guide tray included in the 3D image.

The electronic device displays the position of the guide hole on the image of the guide tray according to the implant design information, and generates a file for implant placement guide processing using the image of the guide tray on which the position of the guide hole is indicated. The electronic device generates a guide hole in the guide tray using an implant placement guide file, and the guide tray is characterized in that the tooth shape of the subject is raised.

In displaying the position of the guide hole, the electronic device generates a guide hole image on the guide tray image based on the vertical axis of the implant fixture included in the implant design information, and displays a deletion area for jig insertion around the guide hole. can do.

Furthermore, the electronic device may transfer a cost corresponding to the number of times of generating the implant placement guide processing file to a predetermined server account.
