For example, when tooth decay occurs, for the treatment of tooth decay, a treatment may be performed in which a portion of a tooth having tooth decay is cut according to a progression stage of the tooth decay, and the cut tooth is restored using an artifact.

For example, there are cases in which cavities develop even to the pulp present in the tooth. In this case, after cutting the tooth in which the decay has occurred, and prior to nerve treatment for the pulp within the cut tooth, crown treatment should be performed.

Here, the crown treatment refers to a treatment in which a crown surrounding the outside of the cut tooth is attached or coupled to the cut tooth. For crown treatment, it is necessary to manufacture a crown that fits the cut tooth. And, it is most important that the crown to be attached to the cut tooth is accurately manufactured. In general, in order to determine whether the crown is properly manufactured, a dental care professional such as a doctor directly attaches the manufactured crown to the patient's teeth and examines the state of the attached crown.

And, as a result of the manual inspection, when the crown is manufactured incorrectly, for example, when the crown and the cut tooth collide with each other or the crown is made smaller than the cut tooth, the corresponding crown must be remanufactured.

Therefore, when the crown is manufactured incorrectly, the patient must visit the dentist additionally, and the crown must be sent back to a factory that manufactured the crown, such as a laboratory, and thus, it is inconvenient to have it corrected or re-manufactured.

Hereinafter, detailed operations performed by the electronic device 300 , 400 or 500 according to the disclosed embodiment will be described with reference to FIGS. 6 to 21 .

An electronic device (eg, 200, 300, 400, or 500) and an operating method thereof according to the disclosed embodiment may provide inconvenience to dental technicians, dentists, and patients when an artifact to be inserted or attached to a tooth is manufactured erroneously. This is to minimize the cost of dental treatment and to increase the efficiency of dental treatment.

Specifically, let's take a case where a patient's teeth are damaged and receive crown treatment. In this case, the patient visits the dentist for dental treatment, and the dentist removes the damaged part of the tooth. Then, the tooth is scanned in order to manufacture a crown to be attached to the tooth from which the damaged part has been removed. In addition, data obtained by scanning teeth may be input to a computer aided design (CAD) system or the like to generate a crown model. Then, an actual crown corresponding to the generated crown model is manufactured. The patient should visit the dentist again when crown fabrication is completed. The dentist may complete the crown treatment by attaching the crown to the teeth so that the manufactured crown covers the damaged teeth of the patient.

In the above example, there may be a case where the crown is mismanufactured. The crown should be manufactured to cover the teeth without colliding with the patient's teeth (eg, abutment teeth), and should be manufactured not to collide with adjacent adjacent teeth or have too large a gap. For example, if it is made larger than the patient's teeth and collides with other adjacent teeth, if it is made smaller than the patient's teeth and cannot be attached to cover the patient's teeth, the adjacent teeth are made smaller than the intended size or thickness When the gap between the fovea increases, at least a portion of the patient's teeth collide with the inside of the crown, and the like.

In this case, the crown has to be manufactured again, and the patient has to visit the dentist again, which is inconvenient. In addition, the dentist must also repeatedly perform crown treatment, which would have ended if the crown had not been manufactured incorrectly.

As described above, in the case of an artificial object that is precisely attached or coupled to a tooth for dental treatment, if it is manufactured incorrectly, the dentist, the dental technician, and the patient all inevitably experience inconvenience.

In the disclosed embodiment, in order to minimize the above-mentioned inconvenience, it is possible to check whether or not the artifact is precisely manufactured or not, before attaching the artifact that is precisely attached or coupled to the teeth to the patient's teeth for dental treatment.

6 is a view for explaining the inlay treatment.

In the disclosed embodiment, the prosthesis to be attached or coupled to the patient's teeth for dental treatment may have an inlay. 6 is a view for explaining inlay treatment, which is a dental treatment for inlay.

Referring to part 610 of FIG. 6 , a case in which a cavity 602 occurs in an upper central portion of a tooth 601 to be treated by dental treatment is illustrated.

Subsequently, referring to a portion 620 of FIG. 6 , the dentist may remove a portion of the tooth 601 where the cavity 602 has occurred. Part 630 of FIG. 6 shows the tooth 601 from which the part where the tooth decay 602 has been removed. The dentist scans the tooth 601 from which the cavity 602 has been removed using a scanner (not shown) or performs an impression operation, and inserts and attaches it to the partial area 631 of the tooth from which the cavity has been removed. An inlay 641 to be used may be manufactured.

Continuingly, referring to portions 640 and 650 of FIG. 6 , by inserting and attaching the manufactured inlay 641 to the partial region 631 of the tooth from which the cavities are removed, the inlay treatment may be completed.

7A is a view for explaining crown treatment.

Referring to FIG. 7A , a tooth to be treated with a crown may be a tooth 720 in which a part of the tooth is broken and the inner nerve is damaged, or a tooth 710 in which the inner nerve is damaged due to caries. Similar to that described with reference to FIG. 6 , by removing or etching the damaged tooth, the tooth 710 may be trimmed in a form that can put a crown on the tooth 710 .

Then, by scanning the trimmed tooth 710 using a scanner (not shown) or performing an impression (impression), the crown 713 formed to completely surround the tooth 710 may be manufactured. Here, the trimmed tooth 710 may be referred to as an 'abutment tooth'. The crown 713 to be attached to the abutment 710 must be manufactured without causing a collision with the abutment or dislocating the abutment from the inside. For example, on the inner surface of the crown that comes into contact with the abutment, there should be no part that collides with the abutment or displaces the abutment. In addition, the crown attached to the abutment 710 should not collide with the at least one tooth 720 and 730 adjacent to the abutment. In addition, the gap or gap between the crown attached to the abutment 710 and at least one tooth 720 and 730 adjacent to the abutment should not be too large. When the gap between the crown attached to the abutment 710 and the at least one tooth 720, 730 adjacent to the abutment is large, food debris gets caught in the at least one tooth 720, 730 adjacent to the crown, leading to inflammation of the gums or tooth decay. This is because it may cause corrosion, etc.

7B is a view for explaining implant treatment. In addition, in FIG. 7B , the same configuration as in FIG. 7A is illustrated using the same reference numerals, and thus overlapping descriptions are omitted.

The implant treatment of FIG. 7B is similar to the crown treatment described with reference to FIG. 7A , but is different in that an abutment 762 of the implant is used instead of the abutment 710 described with reference to FIG. 7A . In addition, although the case where the adjacent tooth 720 disposed on the left side of the abutment 762 in FIG. 7B is a broken tooth is illustrated as an example in FIG. 7A , in FIG. 7B , the case of a normal tooth is illustrated as an example.

Referring to area 750 of FIG. 7B , in the case of implant treatment, a fixture 763 is inserted into the gum, and the abutment 762 is coupled to the fixture 763 . In implant treatment, the fixture 763 may serve as the root of the tooth, and the abutment 762 may serve as the abutment. And, based on the first scan model obtained by scanning the oral cavity into which the abutment 762 is inserted or by scanning the abutment 762, the design of the crown 765 coupled with the abutment 762 A model can be created. The crown 765 coupled to the abutment 762 is also referred to as an implant crown, but hereinafter, it will be referred to as a 'crown 765' for convenience of naming. And, when the crown 765 is manufactured using the generated design model, the crown 765 may be attached to the abutment 762 ( S771 ). Specifically, the crown 765 may be attached to the abutment 762 such that the margin line 767 of the crown 765 and the margin line 761 of the abutment 762 are in close contact. In FIG. 7B , the abutment 762 may be an abutment 762 customized to the patient's oral structure or the patient's teeth.

Referring to area 790 , an oral cavity in which implant treatment is completed by attaching the crown 765 to the abutment 762 is shown.

Hereinafter, a case in which the prosthesis used for dental treatment is the inlay or crown described with reference to FIGS. 6 to 7B will be described as an example. In addition, in the disclosed embodiment, the crown may mean the crown 713 attached to the abutment 710 described in FIG. 7A , and may mean the crown 765 attached to the abutment 762 described in FIG. 7B . there is also For convenience of description, the crown referred to below will be described with reference to the case of the crown 713 attached to the abutment 710 described in FIG. 7A as an example. 8A is a flowchart illustrating a method of providing information for dental treatment according to the disclosed embodiment. Also, FIG. 8A may be a diagram illustrating the flow of operations performed by the electronic device 200 , 300 , 400 or 500 according to the disclosed embodiment. In FIG. 8A , a case in which the information providing method 800 for dental treatment is performed through the electronic device 400 illustrated in FIG. 4 will be described as an example.

The information providing method 800 for dental treatment according to the disclosed embodiment is generated based on a first scan model obtained by scanning an object (eg, a tooth or an impression body corresponding to a tooth) and is attached to the object A design model representing the to-be-imposed artifact is acquired ( S810 ). Specifically, step S810 may be performed by the processor 310 .

Here, the first scan model may be a three-dimensional model representing an object to be subjected to dental treatment. Also, the object may be a tooth to be treated by dental treatment. For example, when crown treatment is performed on a tooth, the tooth may be the abutment 710 described with reference to FIG. 7A .

Alternatively, the object may be an implant tooth for the implant treatment described with reference to FIG. 7B . For example, when implant treatment is performed, the abutment 762 corresponding to the abutment 710 may be used. In this case, the first scan model may be a model obtained by scanning the abutment 762 combined with the fixture for implant treatment. In addition, the crown 765 described with reference to FIG. 7B may be manufactured based on the first scan model obtained by scanning the abutment 762 . Then, a second scan model may be obtained by scanning the crown 765 .

For convenience of description, in the accompanying drawings including FIG. 8A , the case where the object is a tooth is illustrated and described as an example. Here, the tooth may be the abutment 710 described with reference to FIG. 7A . Alternatively, the target tooth may refer to the abutment 762 corresponding to the abutment 710 described in 7b. Hereinafter, for convenience of explanation, a case in which the 'tooth' described below is the abutment 710 described in FIG. 7A will be described as an example.

Specifically, the scanner 100 or the scanner 101 described with reference to FIG. 1 or 2 may scan an object. The object to be scanned may be a tooth, an artificial object corresponding to the tooth, an impression body simulating a tooth, a plaster model corresponding to the tooth, or the like.

Hereinafter, a case in which an object (eg, the abutment 710 described in FIG. 7A ) is scanned using the scanner 100 described in FIG. 1 will be described as an example.

Specifically, the scanner 100 may scan a tooth to be treated to obtain scan data, for example, raw data. The scanner 100 may generate a 3D model or 3D image corresponding to a tooth to be treated by using the raw data. Hereinafter, for convenience of explanation, an image or model representing an object three-dimensionally is collectively referred to as a 'model'.

In addition, hereinafter, for convenience of description, a model generated by scanning a tooth to which an artificial object is to be attached as a tooth to be treated will be referred to as a 'first scan model'. For example, the first scan model may be a model obtained by scanning a tooth that has been trimmed to attach an artifact. For example, as shown in part 630 of FIG. 6 , a first scan model may be obtained by scanning a tooth including a region 631 in which an artificial tooth part to be coupled or attached is etched. As another example, as described with reference to FIG. 7A , the crown 713 is a tooth to be coupled or attached, and a first scan model may be obtained by scanning a tooth trimmed for attachment of the crown. As another example, as described with reference to FIG. 7B , a first scan model may be obtained by scanning the abutment 762 .

Alternatively, data obtained by the scanner 100 , for example, raw data or data corresponding thereto, may be transmitted to at least one of the oral diagnosis apparatus 120 and the server 170 . Then, at least one of the oral diagnosis apparatus 120 and the server 170 may generate the above-described first scan model based on the received data. In addition, at least one of the oral diagnosis apparatus 120 and the server 170 may transmit the generated first scan model to the electronic device 400 . Then, the electronic device 400 may receive the first scan model generated by at least one of the oral diagnosis apparatus 120 and the server 170 through the communication interface 320 . In the above-described example, the processor 310 of the electronic device 400 may acquire the first scan model by receiving the first scan model from at least one of the oral diagnosis apparatus 120 and the server 170 .

Alternatively, data obtained by the scanner 100 , for example, raw data or data corresponding thereto, may be transmitted to the electronic device 400 . Here, data obtained by scanning a tooth to be treated may be transmitted from the scanner 100 to the electronic device 400 . Alternatively, data acquired through the scan may be transmitted from at least one of the oral diagnosis apparatus 120 and the server 170 to the electronic device 400 . Then, the electronic device 400 may receive the raw data obtained through the scan or data corresponding thereto through the communication interface 320 , and may generate a first scan model based on the received data.

As described above, the electronic device 400 is configured based on data received from an external device (eg, at least one of the scanner 100 , the scanner 101 , the oral diagnosis apparatus 120 , and the server 170 ). The first scan model may be generated or the first scan model may be received from an external device (eg, at least one of the scanner 100 , the scanner 101 , the oral diagnosis apparatus 120 , and the server 170 ). .

In the disclosed embodiment, the prosthesis comprises orthodontic devices, implants, artificial teeth, crowns, inlays and onlays, etc. including brackets and wires that can be coupled, attached, or inserted into teeth, gingiva, at least a portion of the oral cavity, and/or the oral cavity. It can be a dental restoration that includes a dental restoration, an orthodontic aid inserted into the oral cavity, and the like. Alternatively, the prosthesis may be a plaster model, impression body, etc. used to manufacture an orthodontic appliance, an implant, an artificial tooth, a dental restoration including a crown, an inlay, an onlay, or the like, an orthodontic auxiliary tool inserted into the oral cavity.

Hereinafter, a case in which the 'artificial object' in step S810 is a crown will be described as an example.

Then, the electronic device 400 may acquire a design model representing an artifact to be attached to a tooth based on the acquired first scan model ( S810 ). Specifically, in step S810, a design model representing an artifact to be attached or coupled to a tooth in three dimensions may be generated through a design based on a computer operation based on the first scan model. Here, the operation of generating the design model may be performed by the processor 310 . Alternatively, the operation of generating the design model may be performed in an external device. In this case, the design model generated in the external device may be transmitted to the electronic device 400 .

For example, in step S810, a design model in which an artificial object to be attached to the tooth is three-dimensionally modeled may be obtained through computer aided design (CAD) based on the first scan model. A device or system for designing an object according to computer-aided design (CAD) may be referred to as a CAD system.

Specifically, the CAD system may generate a design model representing the artifact in three dimensions by designing the artifact to be attached to the trimmed tooth based on the first scan model.

Subsequently, the information providing method 800 for dental treatment acquires a second scan model generated by scanning the artifact manufactured based on the design model ( S820 ). Specifically, step S820 may be performed by the processor 310 .

Specifically, the electronic device 400 generates the second scan model or receives the second scan model from an external device (eg, at least one of the scanner 100 , the scanner 101 , the oral diagnosis apparatus 120 , and the server 170 ). By receiving the second scan model, the second scan model may be obtained.

For example, the scanner ( 100 in FIG. 2 ) may acquire raw data by scanning the artifact. That is, the scanner 100 may scan the actually manufactured artifact. And, similarly to that described in step S810 , the scanner 100 may generate a second scan model based on the obtained raw data.

Alternatively, the raw data obtained by the scanner 100 scanning the artifact may be transmitted to at least one of the oral diagnosis apparatus 120 and the server 170 . Then, at least one of the oral diagnosis apparatus 120 and the server 170 may generate the above-described second scan model based on the received data. In addition, at least one of the oral diagnosis apparatus 120 and the server 170 may transmit the generated second scan model to the electronic device 400 . Then, the electronic device 400 may receive the second scan model generated by at least one of the oral diagnosis apparatus 120 and the server 170 through the communication interface 320 . In the above-described example, the processor 310 of the electronic device 400 may acquire the second scan model by receiving the second scan model from at least one of the oral diagnosis apparatus 120 and the server 170 .

Alternatively, data obtained by the scanner 100 scanning the artifact, for example, raw data or data corresponding thereto, may be transmitted to the electronic device 400 . Here, data obtained by scanning the artifact may be transmitted from the scanner 100 to the electronic device 400 . Alternatively, data obtained through the artifact scan may be transmitted from at least one of the oral diagnosis apparatus 120 and the server 170 to the electronic device 400 . Then, the electronic device 400 may receive raw data obtained by scanning the artifact through the communication interface 320 or data corresponding thereto, and may generate a second scan model based on the received data. In the above-described example, the electronic device 400 may acquire the second scan model by generating the second scan model based on the received data.

Subsequently, the information providing method 800 for dental treatment aligns the first scan model obtained in step S810 and the second scan model obtained in step S820 ( S830 ).

Specifically, step S830 may be performed by the processor 310 . In the disclosed embodiment, in order to identify areas within the artefact that collide with the abutment, a second scan model obtained by scanning the artefact and a first scan model obtained by scanning the abutment may be aligned and compared.

Specifically, in operation S830, the first scan model and the second scan model may be aligned based on a line corresponding to an interface between the object and the artifact. Here, a line corresponding to an interface between the object and the artificial object may be a margin line. Specifically, when the object is an abutment of a tooth or an implant, and the artifact is a crown, a 'line corresponding to an interface between the object and the artifact' may be a margin line.

Specifically, in step S830, when cutting a tooth to be treated, based on a line (eg, a margin line) corresponding to the boundary of the cut surface, the first scan model obtained in step S810 and the first scan model obtained in step S820 The second scan model may be aligned (S830).

As in the example shown in FIGS. 6 to 7A , a tooth to be treated may be cut to attach an artifact. Alternatively, a portion of the tooth to be treated may be cut in order to remove a portion in which caries are present. In addition, an artifact for dental treatment, for example, an inlay, an onlay, a crown, and the like, may be attached to the cut portion. Also, a cross section of a tooth cut for treatment may be referred to as a 'cut surface' or a 'cut surface'. Also, the 'boundary of the cut surface' may mean a boundary where the cut surface and the non-cut surface meet within the tooth. For example, in a tooth trimmed for crown treatment, the 'boundary of the cut surface' may be a margin line.

As in the example shown in FIG. 7B , when the dental treatment is implant treatment, the prosthesis is a crown 765 of the implant, and the crown 765 may be coupled with the abutment 762 . In this case, a line corresponding to the interface where the crown 765 and the abutment 762 are coupled may be the margin line.

Specifically, referring to FIG. 6 , in the case of a tooth to be treated in an inlay, a region 631 is cut, and a cutting surface may exist as shown in the center of the upper surface of the tooth. In the example shown in FIG. 6 , the 'cut surface' for attaching an artifact for dental treatment may be a surface forming the region 631 shown in part 630 . The above-described 'line corresponding to the boundary of the cut surface' may be at least one of 647 lines and 642 lines. Considering the artifact as a standard, for dental treatment, the 'line corresponding to the boundary of the cut surface' in the tooth may be 642 lines. Alternatively, if the cut tooth is considered as a standard, a 'line corresponding to the boundary of the cut surface' in the tooth for dental treatment may be 647 lines.

Specifically, when the artifact is a crown as in the crown treatment described with reference to FIG. 7A , the aforementioned 'line corresponding to the boundary of the cut surface' may be the 711 line. Specifically, when the artifact is a crown, the crown surrounds the cut surface of the tooth, and the tooth and the crown are combined. In this case, the 'border of the cut surface' in the tooth is a line that becomes the boundary between the cut and the remaining part after cutting the tooth, and may mean a 'margin line', which is a line forming a margin. . In addition, the 'boundary of the cut surface' of the tooth may mean a line at which the end line 717 of the crown and the tooth come into contact. In the illustrated example of FIG. 7A , the 'boundary of the cut surface' in the tooth may be the 711 line.

Hereinafter, for convenience of explanation, the artifact is the crown 713 described with reference to FIG. 7A , and the above-described 'line corresponding to the interface between the object and the artifact' is a 'margin line' as an example. .

Specifically, step S830 may include aligning the first scan model and the second scan model combined with the design model.

Specifically, step S830 aligns the first scan model and the second scan model combined with the design model based on the margin line of the object in the design model and the margin line of the object in the second scan model can do.

In addition, step S830 may be performed over two steps.

Specifically, the processor 310 may combine the first scan model and the design model. Then, the processor 310 primarily aligns the design model combined with the first scan model and the second scan model, and sets the firstly aligned design model and the second scan model to 2 based on the margin line. can be sorted sequentially. Specifically, the processor 310 may roughly align the design model and the second scan model by comparative analysis as a whole, and then secondarily perform the fine alignment using the margin line. The above-described two-step alignment operation will be described in detail below with reference to FIG. 15 .

In addition, the alignment operation in step S830 may be performed through a neural network operation based on AI technology. Here, the neural network receives two mutually combinable objects and optimizes the weight values inside the neural network by training the training data (eg, the first scan model and the second scan model) so that the two input objects are aligned. can do. In addition, a desired result can be output by self-learning the input data through a neural network having an optimized weight value.

For example, with a neural network such as a CNN (Convolutional Neural Network), two objects to be aligned, 'first scan model' and 'second scan model', are input, compare and align the two input models, The aligned 'first scan model' and 'second scan model' may be output. As another example, a neural network such as a CNN receives two objects to be aligned, a 'design model combined with a first scan model' and a 'second scan model', and compares and aligns the two input models, The aligned 'design model combined with the first scan model' and the 'second scan model' may be output.

Hereinafter, when a first scan model obtained by scanning a tooth cut (or a trimmed tooth) for dental treatment and a design model corresponding to an artifact are combined, the design model combined with the first scan model is called For convenience, it may be referred to as a 'combination model', and will be described in detail below with reference to FIG. 11 .

In addition, step S830 will be described in detail below with reference to FIGS. 11 to 16A.

Referring back to FIG. 8A , the method 800 for providing information for dental treatment identifies an erroneous part in the second scan model based on the alignment result in step S830, and inserts the information into the identified part in the second scan model. Corresponding information is generated (S840). Specifically, step S840 may be performed by the processor 310 .

For example, step S840 may include, based on the alignment result of step S830, identifying a part that collides with the artificial tooth and the tooth to which the artifact is to be attached, and identifying the colliding part as the mismanufactured part. can

Alternatively, in step S840, based on the alignment result of step S830, identifying a portion colliding between a tooth to which an artificial object is to be attached and at least one tooth adjacent to the tooth, and the colliding portion as the mismanufactured portion It may include the step of identifying.

Alternatively, in step S840, based on the alignment result of step S830, determining whether an interval between a tooth to which an artificial object is to be attached and at least one tooth adjacent to the tooth is equal to or greater than a threshold value, and a portion equal to or greater than the threshold value and identifying as the mismanufactured part. As described above, when the gap between the crown attached to the abutment 710 and the at least one tooth 720 and 730 adjacent to the abutment is large, food debris is caught in the at least one tooth 720 and 730 adjacent to the crown and gums It can cause inflammation or tooth decay. Therefore, even when the distance between the tooth to which the artificial object is to be attached and at least one tooth adjacent to the tooth becomes more than a threshold value, it may be determined that the artificial object is manufactured incorrectly.

Here, the mismanufactured part means that, when an artificial object is attached or coupled to a tooth, discomfort is caused to the tooth, the tooth collides with the tooth, the tooth to which the artificial object is attached collides with at least one adjacent tooth or a malocclusion occurs, or the tooth It may mean a part where the artifact is not manufactured in the desired shape, such as not being properly treated.

Alternatively, the mismanufactured part may refer to a part in which the actually manufactured artifact is different from the design model. Since the design model refers to a computer-based three-dimensional model designed based on a first scan model generated by scanning teeth, an artifact (eg, a crown) must be manufactured exactly the same as the design model. However, errors or errors in manufacturing may occur in the process of manufacturing the artifact. Therefore, if an artifact has a defective part, the artifact must be corrected so that the malfunctioning part is removed. Alternatively, when the degree of mismanufacturing of the mismanufactured part is so great that it is impossible to correct it, there may be a case in which the artifact must be newly remanufactured.

Therefore, in the disclosed embodiment, when a user performing dental treatment, such as a dentist or a dental technician, needs to correct or re-manufacture the artifact due to an error in the production of the artifact, it is possible to quickly and conveniently recognize the erroneous part in the artifact. You can create information that allows you to

Hereinafter, for convenience of naming, the 'information corresponding to the erroneous part' generated in step S840 will be referred to as first information.

The first information may include an image in which the above-described erroneous and non-falsified parts are distinguished from each other in the second scan model obtained by scanning the artifact.

For example, the first information may use at least one of different colors, transparency, patterns, symbols, figures, and texts to distinguish the above-described erroneous and non-erroneous parts in the second scan model from each other. It can be a displayed image.

Alternatively, the first information may include information on at least one of a depth, a thickness, a length, an area, and a volume of the aforementioned mismanufactured part in the second scan model.

In addition, the operation of step S840 may be performed using an operation through a neural network based on the AI technology described in step S830.

For example, with a neural network such as a CNN (Convolutional Neural Network), the 'first scan model' and 'second scan model' aligned in step S830 are input, compare and analyze the two input models, and the second scan A part that may collide with the first scan model and/or a part requiring correction from the second scan model may be extracted from the model, and the extracted part may be output as the first information. As another example, with a neural network such as CNN, the 'design model combined with the first scan model' and the 'second scan model' arranged in step S830 are input, and the two models are compared and analyzed, and the second scan A part that may collide with the first scan model and/or a part requiring correction from the second scan model may be extracted from the model, and the extracted part may be output as the first information.

As another example, with a neural network such as a CNN (Convolutional Neural Network), the 'first scan model' and 'second scan model' aligned in step S830, and the position and arrangement information of teeth adjacent to the tooth to be treated is input, compared and analyzed to extract a part in the second scan model that may collide with the first scan model, and/or a part that needs to be corrected in the second scan model, and use the extracted part as the first information can be output as

It can be done (S830). The artifact represented by the second scan model 1200 is manufactured based on the design model 1120 . Accordingly, the design model 1120 and the second scan model 1200 have similar overall shapes. After aligning the design model 1120 and the second scan model 1200 , the mismanufactured part may be identified based on the alignment result in step S840 .

Conventionally, it is only possible to determine whether the crown is properly manufactured or incorrectly manufactured only by attaching or attaching a manufactured artifact (eg, a crown) to an actual patient's teeth, and actually moving or observing the tooth to which the crown is attached. could

If there is a mismanufactured part in the crown, the crown must be sent back to a crown manufacturing shop such as a dental laboratory for correction. In addition, the patient must visit the dentist again and receive treatment for attaching the crown to the tooth. Accordingly, due to the crown correction operation, the patient's revisit to the dentist, and the repeated treatment of the dentist, inconvenience of dental treatment and inefficiency in crown manufacturing are inevitable.

For example, in crown treatment, the crown is combined with the tooth to be treated with the crown in a form surrounding the trimmed tooth. Accordingly, in the combined model 1100 , the design model 1120 may have the shape of a crown surrounding the trimmed teeth.

When the design model 1120 is obtained, an artifact (eg, a crown) may be manufactured based on the design model 1120 .

Specifically, the margin line 1230 may have a band shape formed by the inner surface bonding line 1232 of the second scan model 1200 and the outer surface bonding line 1231 of the second scan model 1200 . . Specifically, the margin line 1230 of the crown corresponds to the boundary of the cutting surface of the tooth 1020, and the line corresponding to the boundary of the cutting surface in the tooth 1020 (eg, 711 in FIG. 7A ) and the crown The margin line 1230 may be in contact with or coupled to each other.

Specifically, the margin line of the second scan model 1200 is identified based on the primarily aligned design model 1120 and the second scan model 1200 , and the margin line 1410 of the design model 1120 and Based on the margin line 1230 of the second scan model 1200 , the design model 1120 combined with the first scan model 1010 and the second scan model 1200 may be aligned ( S1530 ). Accordingly, the alignment of the first scan model 1010 and the second scan model 1200 may be completed. Step S1530 will be described in detail below with reference to FIGS. 16B to 17 .

First, an operation for obtaining a margin line in the second scan model 1200 will be described in detail with reference to FIG. 16B .

In the disclosed embodiment, in a state in which the design model 1120 and the second scan model 1200 are primarily aligned, the margin line 1230 of the second scan model 1200 using the design model 1120 is information can be obtained. Specifically, when the design model 1120 and the second scan model 1200 are primarily aligned, a portion corresponding to the margin line 1410 of the design model 1120 in the second scan model 1200 is first It can be identified by the margin line 1230 of the two-scan model 1200 . Here, the margin line 1230 may be identified automatically or manually.

Specifically, the processor 310 may automatically extract a margin line by analyzing the design model 1120 and the second scan model 1200 that is primarily aligned with the second scan model 1200 .

Referring to FIG. 16B , as described with reference to FIG. 16A , in the second scan model 1200 aligned with the design model 1120 combined with the first scan model, the aforementioned proximity region 1650 may be set.

For example, the processor 310 may automatically set the proximity area 1650 . Specifically, the processor 310 may set the proximity region of the design model 1120 and the second scan model 1200 that are primarily aligned with the margin points included in the margin information of the design model 1120 . . In addition, the margin line of the second scan model 1200 may be searched within the proximity area set in the second scan model 1200 . Specifically, in the second scan model 1200 aligned with the design model 1120, the area of the second scan model 1200 corresponding to the margin line 1410 of the design model 1120 is defined as a 'proximity area 1650'. ' can be set. Here, the adjacent region 1650 may mean an adjacent region of the margin line including the margin line. In detail, the proximity area may mean an area within the second scan model 1200 corresponding to 'a portion adjacent to the margin line 1410 including the margin line 1410 in the design model 1120'. Accordingly, the processor 310 may identify the margin line of the second scan model 1200 based on the set proximity area 1650 .

Alternatively, the proximity region 1650 for extracting the margin line from the second scan model 1200 may be manually set based on a user input.

Specifically, the user may input a user input for designating the proximity area 1650 in the second scan model 1200 to the electronic device (eg, 200, 300, 400, or 500). Then, the processor 310 performs a user input (eg, a proximity area) received through a user interface (eg, 350 of FIG. 5 ) included in the electronic device (eg, 200 , 300 , 400 or 500 ). Based on a user input that designates or identifies 1650 ), the proximity area 1650 may be set. Subsequently, the processor 310 may perform a margin line search operation within the proximity area 1650 of the second scan model 1200 .

As another example, the processor 310 analyzes the second scan model 1200 to be an area corresponding to the margin line 1410 of the design model 1120 , and a surface corresponding to each of the inner and outer surfaces of the artifact. The edges connecting them can be extracted as margin lines. Alternatively, the processor 310 may analyze the second scan model 1200 that is primarily aligned with the design model 1120 and extract the lowermost perimeter of the artifact as a margin line.

Also, the margin line 1230 identified in the second scan model 1200 may be output through the user interface screen.

Specifically, referring to FIG. 17 , the user interface screen 1600 may be a screen including the second scan model 1200 on which the identified margin line 1230 is displayed. In the disclosed embodiment, the processor 310 may control the user interface screen 1600 including the second scan model 1200 on which the margin line 1230 is displayed to be output through the display 330 .

In addition, the user interface screen 1600 may include measurement tools 1610 for measuring specific numerical values such as width, length, spacing, angle, and/or area of the margin line 1230 . The processor 310 may obtain and provide measurement values corresponding to a user request based on a user input for selecting or manipulating the measurement tools 1610 . That is, the user may check specific numerical values for the margin line 1230 by inputting a user input for selecting the measurement tools 1610 . For example, the user may input a user input for measuring the thickness (or width) of some points of the margin line 1230 to the electronic device (eg, 200, 300, 400, or 500). Then, the electronic device (eg, 200 , 300 , 400 , or 500 ) may perform a measurement corresponding to the user input and provide the measurement result 1630 on the user interface screen 1600 .

Alternatively, the user may manually change or reset the margin line in the second scan model 1200 . For example, the processor 310 of the electronic device (eg, 200, 300, 400, or 500) receives a user input (eg, 350 of FIG. 5 ) received through an internally included user interface (eg, 350 of FIG. 5 ). For example, an operation of changing or resetting the margin line in the second scan model 1200 may be performed based on a user input for designating or identifying the margin line. In this case, the processor 310 may control the user interface screen 1600 including the second scan model 1200 displaying the margin line identified based on the user input to be output through the display 330 .

Misfabricated portions 1810 and 1820 illustrated in FIG. 18 may represent portions in which the inner surface of the crown collides with a trimmed tooth (eg, an abutment). Specifically, the mismanufactured parts 1810 and 1820 may mean parts that need to be corrected, such as by cutting off a crown. In addition, in the second scan model 1830 , portions other than the mismanufactured portions 1810 and 1820 may be well-made portions as intended.

In addition, the processor 310 may generate an image in which the mismanufactured parts 1810 and 1820 are displayed in the second scan model 1830 and provide it to the user.

For example, when the identified portions 1910 and 1930 collide with an adjacent tooth by 0.2 mm, set to a corresponding level (eg, collision depth of 0.05 0.250 mm) in a plurality of color levels 1950 The portions 1910 and 1930 identified by the color 1951 may be displayed.

For example, in scanning a tooth to be treated to obtain a first scan model, the tooth to be treated and at least one adjacent tooth may be scanned together. In this case, the first scan model may be a model representing a tooth to be treated and at least one tooth adjacent thereto. Referring back to FIG. 10 , the first scan model may be a model 1000 including a tooth 1020 to be treated and teeth adjacent thereto. Then, based on the result of aligning the second scan model 1900 and the first scan model 1000, it is determined whether the second scan model 1900 and at least one tooth adjacent to the tooth to be treated collide. will be able

The user interface screen 1901 may be generated by distinguishing the different levels from each other and displaying the differentiated levels differently using at least one of different colors, transparency, patterns, symbols, figures, and texts.

For example, when the identified portion 1910 collides with an adjacent tooth by 0.4 mm, the identified portion 1910 is displayed in yellow, and when the identified portion 1930 collides with an adjacent tooth by 0.7 mm, the identified portion ( 1910) can be displayed in yellow green.

In addition, when the user points to a specific point (eg, 1905 ) in the second scan model 1900 in which the identified parts 1910 and 1930 are displayed, the processor 310 corresponds to the pointed point 1905 . At least one measurement value 1960 may be controlled to be output.
