Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a method, apparatus, electronic device, and storage medium for recommending bowwires. Background Art

[0002] Orthodontic treatment involves periodically wearing braces (also known as dental braces) on patients. Each brace is designed to move a specific tooth a certain amount. Because the braces designed to move the teeth do not completely coincide with the current position and posture of the patient's teeth, the corresponding teeth can move in the direction of the designed movement, thereby gradually changing the position and posture of the teeth.

[0003] Traditionally, dentists assess a patient's teeth by visually observing their current condition. Therefore, minimizing manual intervention to obtain appropriate orthodontic reference information and conserve manpower has become a pressing technical challenge. Summary of the Invention

[0004] This application provides an improved method, apparatus, electronic device, and storage medium for recommending bowwires.

[0005] This application provides a method for recommending archwires, including:

[0006] Acquire images of the teeth of an object using an image acquisition device;

[0007] According to the parameters to be corrected corresponding to the key process nodes of orthodontic treatment, the tooth image is subjected to distortion analysis to obtain the parameter information to be corrected for the distorted parts of the teeth; the parameter information to be corrected includes tooth alignment parameter information and tooth leveling parameter information.

[0008] Based on the tooth alignment parameters and tooth leveling parameters, and compared with the corresponding reference benchmarks, orthodontic reference information for a reference scheme corresponding to the tooth alignment parameters and tooth leveling parameters is generated; the orthodontic reference information for the reference scheme includes the archwire type and the single-use cycle.

[0009] The correction reference information of the reference scheme is displayed on the display interface.

[0010] Furthermore, the tooth alignment parameters include tooth crowding and / or tooth misalignment.

[0011] The step of comparing the tooth alignment parameters and tooth leveling parameters with corresponding reference benchmarks to generate orthodontic reference information for a reference scheme corresponding to the tooth alignment parameters and tooth leveling parameters includes:

[0012] Based on the correspondence between different degrees of tooth crowding and the recommended archwire model of the initial wire, the archwire model of the initial wire corresponding to the tooth crowding value of the malformed tooth site is generated, as well as the single-use cycle of the archwire model of the initial wire.

[0013] The degree of crowding and misalignment of the teeth in the malformed area are superimposed to adjust the single-use cycle of the archwire model of the initial wire, and to determine whether to remove the wire based on the archwire model of the initial wire, so as to obtain the archwire model of the initial wire.

[0014] Furthermore, the step of superimposing the crowding degree and misalignment degree of the teeth at the malformed site, adjusting the single-use cycle of the archwire model of the initial wire, and determining whether to remove the wire based on the archwire model of the initial wire includes:

[0015] Using the degree of tooth misalignment at the site of the tooth deformity, and based on the correspondence between different degrees of tooth misalignment and the archwire thinning level, determine whether the archwire model of the initial wire needs to be thinned.

[0016] When archwires of the initial wire type are unwired, determine the archwire unwire level corresponding to the degree of tooth misalignment at the site of tooth malformation and the first usage duration to be increased in a single usage cycle of the initial wire type.

[0017] Based on the stated bowwire unwinding grade, the bowwire of the initial bowwire model is unwound, and the single-use cycle of the bowwire model of the initial bowwire is increased according to the increased first usage time.

[0018] Furthermore, based on the degree of tooth misalignment at the site of tooth malformation, and according to the correspondence between different degrees of tooth misalignment and archwire thinning levels, determining whether archwire thinning is required for the initial archwire model, includes:

[0019] Choose any one of the following: the horizontal misalignment of the tooth deformed part, the vertical misalignment of the tooth deformed part, the rotational misalignment of the tooth deformed part, and the axial misalignment of the tooth deformed part.

[0020] Based on the selected degree of misalignment at the location of the tooth deformity, and according to the correspondence between the corresponding degree of tooth misalignment and the archwire thinning grade, it is determined whether the archwire of the initial wire should be thinned based on the archwire model of the initial wire.

[0021] Furthermore, based on the degree of tooth misalignment at the site of tooth malformation, and according to the correspondence between different degrees of tooth misalignment and archwire thinning levels, determining whether archwire thinning is required for the initial archwire model, includes:

[0022] The maximum misalignment is selected from the horizontal misalignment, vertical misalignment, rotational misalignment, and axial misalignment of the malformed tooth.

[0023] Based on the maximum misalignment of the malformed tooth location, and according to the correspondence between the maximum tooth misalignment and the recommended archwire thinning level, it is determined whether the archwire of the initial wire should be thinned based on the archwire model of the initial wire.

[0024] Furthermore, the tooth leveling parameters include tooth overbite.

[0025] The step of comparing the tooth alignment parameters and tooth leveling parameters with corresponding reference benchmarks to generate orthodontic reference information for a reference scheme corresponding to the tooth alignment parameters and tooth leveling parameters includes:

[0026] Using the overbite condition of the malformed tooth location, and based on the correspondence between different overbite conditions and recommended archwire models for terminal wires, an archwire model for the terminal wire corresponding to the overbite condition value of the malformed tooth location is generated, along with the single-use cycle of the archwire model for the terminal wire.

[0027] Furthermore, the tooth leveling parameters also include tooth coverage.

[0028] The method further includes: using the tooth coverage of the malformed tooth site, and based on the correspondence between different tooth coverage and the recommended archwire model for adjusting the terminal wire, determining whether to adjust the archwire model of the terminal wire, and whether to adjust the single-use cycle of the archwire model of the terminal wire.

[0029] When the archwire model of the terminal wire is determined, the adjustment data corresponding to the tooth misalignment value of the tooth malformation site and the second usage time increased per single usage cycle of the archwire model of the terminal wire are determined.

[0030] Based on the adjustment data, the archwire type of the terminal wire is adjusted, and the single-use cycle of the archwire type of the terminal wire is increased according to the increased second usage time;

[0031] The step of displaying the correction reference information of the reference scheme on the display interface includes:

[0032] The display interface shows the single-use cycle of the adjusted terminal wire and the bowwire model of the added terminal wire in the reference scheme.

[0033] Furthermore, the parameter information to be corrected includes torque adjustment parameters; the torque adjustment parameters include the adjustment amount of the torque of the terminal filament;

[0034] The method further includes: adjusting the torque of the terminal filament and the adjustment time period;

[0035] The step of displaying the correction reference information of the reference scheme on the display interface includes:

[0036] The adjustment amount of the torque and the adjustment time period of the reference scheme are displayed on the display interface.

[0037] Furthermore, it receives measurement information input by the user regarding the dental image;

[0038] Receive the parameters to be corrected selected by the user from the parameters to be corrected corresponding to the key process nodes of orthodontic treatment;

[0039] Based on the parameters to be corrected, and according to the measurement information, the tooth image is subjected to distortion analysis to obtain the parameter information of the distorted tooth location.

[0040] Furthermore, the parameter information to be corrected includes gap closure parameters; the gap closure parameters include the amount of tooth movement after extraction; the amount of tooth movement after extraction is the average of the difference between the extraction gaps and the crowding on both sides;

[0041] The method further includes: outputting the amount of tooth movement during extraction;

[0042] Based on the amount of tooth movement after extraction, the corresponding row of teeth is used to generate the gap-closing method, anchorage strength, and archwire type for the remaining teeth (excluding the extracted tooth). This allows the archwire on the molars to be locked relative to the corresponding bracket according to the gap-closing method and anchorage strength, while the archwire on the anterior teeth moves relative to the corresponding bracket, thereby controlling the locking anchorage and closing the gaps for the remaining teeth.

[0043] The step of displaying the correction reference information of the reference scheme on the display interface includes:

[0044] The display interface shows the tooth movement amount, gap closing method, anchorage strength, and archwire model of the reference scheme.

[0045] Furthermore, acquiring the image of the object's teeth captured by the image acquisition device includes:

[0046] Acquire tooth data of key points of each row of teeth of the object through image acquisition equipment to obtain a three-dimensional model of the corresponding row of teeth;

[0047] The process involves performing distortion analysis on the dental image according to the parameters to be corrected corresponding to the key process nodes of orthodontic treatment, to obtain the parameter information for the distorted areas of the teeth, including:

[0048] Identify the key points of each tooth in the corresponding row of teeth;

[0049] By comparing the differences between the key points of each row of teeth and the reference benchmark of the corresponding row of teeth as a whole, the location of the dental malformation in the corresponding row of teeth and the parameters to be corrected for the dental malformation are determined.

[0050] This application provides a bowwire recommending device, comprising:

[0051] The tooth image acquisition module is used to acquire images of the teeth of an object captured by an image acquisition device;

[0052] The parameter information generation module is used to perform distortion analysis on the tooth image according to the parameters to be corrected corresponding to the key process nodes of orthodontic treatment, and obtain the parameter information to be corrected for the distorted parts of the teeth; the parameter information to be corrected includes tooth alignment parameter information and tooth leveling parameter information.

[0053] The orthodontic reference generation module is used to compare the tooth alignment parameter information and tooth leveling parameter information with the corresponding reference benchmarks to generate orthodontic reference information for a reference scheme corresponding to the tooth alignment parameter information and tooth leveling parameter information; the orthodontic reference information for the reference scheme includes the archwire type, single use cycle and single use period.

[0054] The correction reference information correction module is used to display the correction reference information of the reference scheme on the display interface.

[0074] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with one or more embodiments of this specification. Rather, they are merely examples of apparatuses and methods consistent with some aspects of one or more embodiments of this specification as detailed in the appended claims.

[0075] It should be noted that the steps of the corresponding methods are not necessarily performed in the order shown and described in this specification in other embodiments. In some other embodiments, the methods may include more or fewer steps than described in this specification. Furthermore, a single step described in this specification may be broken down into multiple steps in other embodiments; and multiple steps described in this specification may be combined into a single step in other embodiments.

[0076] This application provides an archwire recommendation method. The method involves acquiring images of the patient's teeth using an image acquisition device; performing distortion analysis on the images according to the parameters to be corrected corresponding to key process nodes in orthodontic treatment to obtain corrective parameter information for the distorted areas of the teeth; the corrective parameter information includes tooth alignment parameters and tooth leveling parameters; comparing the tooth alignment parameters and tooth leveling parameters with corresponding reference benchmarks to generate orthodontic reference information for a reference scheme corresponding to the tooth alignment parameters and tooth leveling parameters; the orthodontic reference information for the reference scheme includes the archwire model and single-use cycle; and displaying the orthodontic reference information for the reference scheme on a display interface.

[0077] In this embodiment, dental images are acquired using an image acquisition device, distortion information is analyzed, and finally, orthodontic reference information for the reference treatment plan is displayed. This facilitates the acquisition of the parameters to be corrected. Furthermore, the automatic display of the orthodontic reference information eliminates the need for manual calculation, saving manpower and allowing dentists or users to easily view and monitor the orthodontic progress.

[0078] The bowwire recommendation method of this application embodiment can be applied to electronic devices. The aforementioned electronic device can be a PC (Personal Computer) device. The PC device can include, but is not limited to, desktop computers, tablet computers, or laptop computers. Furthermore, the bowwire recommendation method can be applied to an application program (APP) of the electronic device.

[0079] Figure 1 The diagram shown is a flowchart illustrating the bowwire recommendation method according to an embodiment of this application.

[0080] like Figure 1 As shown, the recommended method for archwire may include, but is not limited to, the following steps 110 to 140:

[0081] Step 110: Obtain the image of the object's teeth acquired by the image acquisition device.

[0082] The aforementioned image acquisition device is used to acquire images of the teeth of an object. Image acquisition devices may also include, but are not limited to, cameras, video cameras, scanners, fluoroscopic devices, and other devices with photographic capabilities. Other devices with photographic capabilities include mobile phones.

[0083] The objects mentioned above can be human bodies, animal bodies, etc. Human bodies may include, but are not limited to, users who need orthodontic treatment. These users can stay informed about their dental condition.

[0084] Step 120: Perform distortion analysis on the dental images according to the parameters to be corrected corresponding to the key process nodes of orthodontic treatment, obtaining the parameter information to be corrected for the malformed areas. This parameter information includes tooth alignment parameters and tooth leveling parameters. A malformed area refers to a location where teeth are not developing or aligned correctly. Malformed areas may include misaligned, crooked, missing, or extra teeth.

[0085] The above-mentioned parameters to be corrected reflect the basic parameters that need to be mastered for orthodontic treatment. The tooth alignment parameters included in the above-mentioned parameters are data or values ​​of parameters that align the teeth. The tooth leveling parameters included in the above-mentioned parameters are data or values ​​of parameters that level the teeth.

[0086] Of course, the above-mentioned parameters for the malformed tooth location can be automatically generated based on a pre-set formula for the parameters. Alternatively, the above-mentioned parameters can be user-inputted. Please see below for details.

[0087] like Figure 2 As shown, the key process nodes described above in this application embodiment can be used to implement the key process nodes required for generating orthodontic reference information for teeth. These key process nodes may include multiple preset key process nodes. These preset key process nodes may include, but are not limited to, at least two of the following: alignment process nodes, leveling process nodes, anchorage control process nodes, gap closing process nodes, and fine adjustment process nodes. Thus, by collecting the parameters to be corrected from multiple preset key process nodes, more accurate orthodontic reference information for the reference scheme can be obtained.

[0088] Step 130: Based on the tooth alignment parameter information and tooth leveling parameter information, compare with the corresponding reference benchmarks to generate orthodontic reference information for the reference plan corresponding to the tooth alignment parameter information and tooth leveling parameter information; the orthodontic reference information for the reference plan includes the archwire type and the single-use cycle.

[0089] The aforementioned archwire is a tool used to install itself within the archwire slot of a bracket on the teeth to complete orthodontic treatment. The bracket is fixed to the teeth with adhesive, and each bracket has an archwire slot in which the archwire is installed. In the embodiments of this application, the model of the initial wire (also called the first archwire) and the model of the terminal wire (also called the last archwire) are determined first, and then the transition wires between the initial and terminal wires are determined. These wires are selected from small cross-sections to large cross-sections. Thus, determining the initial and terminal wires first, and then determining the other transition wires (the specific order of determination is described below), is simple, fast, and efficient, and can shorten the orthodontic cycle.

[0090] like Figures 3a to 3f The bowwire models shown correspond to different thicknesses; the smaller the model number, the smaller the cross-section. The bowwires in this application include square bowwires with a square cross-section; the longer side of the square cross-section of the square bowwire is greater than or equal to 0.012 mm and less than or equal to 0.025 mm; correspondingly, the shorter side of the square cross-section of the square bowwire is greater than or equal to 0.005 mm and less than or equal to 0.012 mm. Thus, compared to round bowwires, which cannot express torque and alignment, square bowwires can express torque and alignment. During the leveling process, square bowwires require less force. At the same time, square bowwires possess the advantages of the flexibility and precise torque of square wires.

[0091] like Figure 3aAs shown, the long side of the square cross-section of the No. 1 square archwire can be 0.025mm, and the short side can be 0.006mm. Figure 3b As shown, the long side of the square cross-section of the No. 2 square archwire can be 0.023 mm, and the short side can be 0.008 mm. Figure 3c As shown, the long side of the square cross-section of the No. 3 square archwire can be 0.022mm, and the short side can be 0.010mm. Figure 3d As shown, the long side of the square cross-section of the No. 4 square archwire can be 0.025mm, and the short side can be 0.014mm. Figure 3e As shown, the long side of the square cross-section of the No. 5 square archwire can be 0.025mm, and the short side can be 0.016mm. Figure 3f As shown, the long side of the square cross-section of the No. 6 square bowwire can be 0.025mm and the short side can be 0.019mm.

[0092] The above-mentioned single-use cycle reflects the recommended follow-up appointment frequency for orthodontic treatment. The single-use cycle refers to the reference usage cycle generated each time the archwire is used for orthodontic treatment.

[0093] The corrective reference information for the above-mentioned reference plan may also include the total duration of use. The total duration of use can be the sum of multiple recommended follow-up appointments (also known as the total course of treatment).

[0094] The aforementioned tooth alignment parameters are used to reflect whether each row of teeth is correctly aligned. For example, tooth alignment parameters may include, but are not limited to, tooth crowding and / or tooth misalignment. Tooth crowding is the difference between the length required for tooth alignment and the actual length of the dental arch. The numerical values ​​and / or content of the tooth alignment parameters in this document are referred to as tooth alignment parameter information. For example, if the length required for tooth alignment is 10 millimeters, and the actual length of the dental arch is 8 millimeters, then an additional 2 millimeters are needed. This 2 millimeters is referred to as the tooth crowding parameter information.

[0095] The above-mentioned orthodontic parameters are used to reflect whether each row of teeth is level. For example, orthodontic parameters may include, but are not limited to, overbite and / or occlusion. The numerical values ​​and / or content of the orthodontic parameters in this article may be referred to as orthodontic parameter information.

[0096] The aforementioned reference benchmarks serve as the basis for comparing the information of the parameters to be corrected. These reference benchmarks can be pre-generated correspondences or user-defined standards. Further, step 130 may include generating, based on the information of the parameters to be corrected at the site of the tooth malformation and according to the correspondence between the information of the parameters to be corrected and the suggested archwire model, an archwire model corresponding to the information of the parameters to be corrected at the site of the tooth malformation, and the single-use cycle of the archwire model. For detailed explanation, please refer to the following text.

[0097] Step 140: Display the correction reference information of the reference scheme on the display interface.

[0098] The aforementioned display interface may be an integrated display interface of the aforementioned electronic device, and / or a display interface separate from the aforementioned electronic device. The aforementioned display interface can be used to present the aforementioned orthodontic reference information. This orthodontic reference information may include at least one of the following: the user's basic information, the archwire parameters required for the user's orthodontic treatment, and the single-use cycle. The user's basic information is used to obtain auxiliary information for the reference plan. For example, the user's basic information may include, but is not limited to, the user's name, age, and / or bone age.

[0099] The above reference scheme is used to perform orthodontic treatment on areas of dental malformation. This reference scheme can be a pre-made table template. These pre-made table templates pre-define the items corresponding to the orthodontic parameters based on the key process nodes of orthodontic treatment. After generating the orthodontic parameter information, the above orthodontic reference information is added to the corresponding items in the pre-made table template, forming a pre-made table template with added information, which serves as a reference scheme containing orthodontic reference information. Specifically, the table below shows the orthodontic reference information displayed using the pre-made table template with added information.

[0100] In this embodiment, tooth images are acquired using an image acquisition device, distortion information is analyzed, and finally, orthodontic reference information for a reference treatment plan is provided. This facilitates the acquisition of the parameters to be corrected. Furthermore, the orthodontic reference information for the reference treatment plan is automatically displayed, eliminating the need for manual calculation and saving manpower. It also allows dentists or patients to easily view and monitor the orthodontic progress. Additionally, the orthodontic reference information can serve as a standardized operating procedure, simplifying dentistry and reducing reliance on individual dentists' experience, thereby minimizing potential deviations due to insufficient experience.

[0101] In combination with the above Figure 1 As shown, step 110 above can further include acquiring tooth data of key points of each row of teeth of the object through an image acquisition device, to obtain a three-dimensional model of the corresponding row of teeth. This results in a more realistic and comprehensive three-dimensional model of the teeth's spatial information.

[0102] In some examples of step 110 above, a 3D scanner can be used to scan inside the oral cavity. In this embodiment of the application, a 3D model of the corresponding teeth is obtained by using a 3D scanner.

[0103] In some other examples of step 110 above, 1) a three-dimensional skeletal perspective image of the object is acquired through a fluoroscopic device. The fluoroscopic device can be, but is not limited to, a fluoroscopic machine. 2) Dental data of key points of each row of teeth in the three-dimensional skeletal perspective image of the object is identified. 3) Three-dimensional image data is rendered based on the data of key points of each row of teeth to obtain a three-dimensional model of the corresponding row of teeth, wherein the corresponding row of teeth can include, but is not limited to, the upper and / or lower teeth. Thus, by rendering three-dimensional image data of key points of the upper and lower teeth, three-dimensional models of the upper and lower teeth are obtained respectively. The above-mentioned three-dimensional skeletal perspective image can be an X-ray image. This provides more realistic and comprehensive spatial information of the teeth.

[0104] Before performing orthodontic surgery, to allow doctors, diagnosticians, or users to better observe the subject's skeletal structure, the aforementioned 3D skeletal perspective image can display the subject's dental skeleton, the skull skeleton where the teeth are located in the oral cavity, and the limb skeleton. Of course, the user's bone age data can be determined through the limb skeleton in the 3D skeletal perspective image. The bone age data is then added to the corresponding field in a pre-made table template, serving as a reference scheme for including bone age data.

[0105] Accordingly, in the first embodiment of step 120 above, (1) the key points of each tooth in the corresponding row of teeth are identified. The key points of each tooth are the pixels in the object's teeth in the two-dimensional skeletal perspective image.

[0106] (2) Compare the differences between the key points of each row of teeth and the reference benchmark of the corresponding row of teeth to determine the malocclusion sites and the parameters to be corrected for the malocclusion sites. The reference benchmark of the corresponding row of teeth refers to the positions of the key points where most teeth in each row are in normal positions. In this way, more accurate parameters to be corrected are automatically obtained, reducing manual measurement, saving manpower, and reducing errors caused by long-term work fatigue. Furthermore, the automatic display of the orthodontic reference information of the reference plan improves the automation of the entire process.

[0107] This embodiment of step 120 is similar to the first embodiment of step 120. Compared with the first embodiment of step 120, in this embodiment of step 120, 1> receiving measurement information input by the user for the tooth image.

[0108] The above measurement information reflects information related to the parameters to be calibrated, obtained by the user through professional measurement equipment.

[0109] The user measures teeth images, inputting measurement information related to the parameters to be corrected. These teeth images may include, but are not limited to, the aforementioned 3D model. The measurement information may include key points input by the user that are related to the parameters to be corrected, and subsequent measurement information can be obtained based on these key points.

[0110] 2> Receive the parameters to be corrected selected by the user from the parameters to be corrected corresponding to the key process nodes of orthodontic treatment.

[0111] In this embodiment, "user" refers to the user who measured the data. This user may include, for example, one or more doctors and professional support personnel.

[0112] 3. Based on the parameters to be corrected, and according to the measurement information, perform distortion analysis on the tooth image to obtain the parameter information to be corrected for the distorted tooth location.

[0113] In the first example, the key points related to the parameters to be corrected may include, but are not limited to, key points related to tooth crowding input by the user. Next, the system receives user input of the required length for tooth alignment related to tooth crowding, as well as the actual length of the dental arch. Then, it receives the user input of the selected degree of tooth crowding. Finally, the difference between the required length and the actual length of the dental arch is calculated to obtain a numerical value for tooth crowding.

[0114] In the second example, the key points related to the parameters to be corrected may include, but are not limited to, key points related to the degree of tooth misalignment input by the user. Next, the system receives user input measuring the location of the malformed tooth and the actual position of the dental arch, which are related to the degree of tooth misalignment. Then, it receives the user input selecting the degree of tooth crowding. Finally, the system calculates the relative position between the location of the malformed tooth and the actual position of the dental arch to obtain a numerical value for the degree of tooth misalignment.

[0115] In the third example, the key points related to the parameters to be corrected may include, but are not limited to, key points related to the overbite condition input by the user. Next, the system receives measured longitudinal distances of the upper and lower teeth related to the overbite condition, input by the user. Then, it receives the selected overbite condition input by the user. Finally, based on the longitudinal distances of the upper and lower teeth, the vertical distance between the upper teeth and the biting lower teeth is calculated to obtain the overbite condition value.

[0116] In the fourth example, the key points related to the parameters to be corrected may include, but are not limited to, key points related to tooth overjet input by the user. Next, the system receives measured horizontal distances between the anterior teeth and mandibular teeth, both related to tooth overjet. Then, it receives the user's selected tooth overjet. Finally, based on the horizontal distances of the anterior teeth and mandibular teeth, the system calculates the horizontal distance of the anterior teeth relative to the mandibular teeth to obtain the tooth overjet numerical value.

[0117] In this embodiment, the user can assist in measuring information related to the parameters to be corrected. Furthermore, the user can control the progress of key process nodes in orthodontic treatment by selecting the parameters to be corrected. Simultaneously, the user can manually control the acquisition of the corrected parameter information for the malformed areas of the teeth.

[0118] Figure 4 As shown Figure 1 A schematic diagram illustrating tooth crowding in the recommended archwire method.

[0119] like Figure 4 As shown, the black line represents the required dental arch length, and the line with the square represents the available dental arch length.

[0120] Combination Figure 1 , Figure 2 The aligned process nodes shown Figure 4 As shown, step 130 above can be implemented through the following various embodiments:

[0121] In the first embodiment of step 130 above, A, based on the correspondence between different degrees of tooth crowding and the archwire model of the recommended initial wire, generate the archwire model of the initial wire corresponding to the tooth crowding value of the malformed tooth location, and the single-use cycle of the archwire model of the initial wire.

[0122] Different degrees of tooth crowding reflect different levels of crowding. Each level of crowding corresponds to a recommended initial archwire size. The relationship between different degrees of tooth crowding and recommended initial archwire sizes can be expressed as a functional relationship. Alternatively, the relationship can be presented as a table, as shown in Table 1 below:

[0126] B. By superimposing the crowding and misalignment of the teeth at the malformed site, the single-use cycle of the initial archwire model is adjusted, and it is determined whether to remove the wire based on the initial archwire model to obtain the final archwire model. The above-mentioned wire removal is used to reflect the removal of a single-level or multi-level thinner wire.

[0127] The single-use cycle for adjusting the bowwire type of the initial wire mentioned above corresponds to whether or not the wire is unwound. In the embodiments of this application, the single-use cycle for adjusting the bowwire type of the initial wire includes increasing the single-use cycle of the bowwire type of the initial wire.

[0128] For example, if the crowding of the teeth in the malformed area is 5mm, then archwire No. 2 is selected. Considering the degree of tooth misalignment in the malformed area, if a step back is required, then archwire No. 1 is selected as the initial wire.

[0129] In this embodiment of the application, the degree of tooth misalignment can be superimposed on the degree of tooth crowding to obtain a more accurate archwire model for the initial wire.

[0130] Figures 5a to 5d As shown Figure 1 The diagram shows the tooth misalignment in various directions for the recommended archwire method.

[0131] like Figures 5a to 5d As shown, combined with Figure 4 As shown, step B above may further include steps ① to ④ as follows:

[0132] Step 1: Using the degree of tooth misalignment at the site of tooth malformation, and based on the correspondence between different degrees of tooth misalignment and the archwire thinning level, determine whether archwire thinning is required for the initial archwire model.

[0133] The above-mentioned bowwire thinning grades are used to reflect whether the bowwire has thinned by one or more grades.

[0134] Different degrees of tooth misalignment reflect different levels of tooth misalignment. Each level of misalignment corresponds to a specific archwire type and its reduction details. The correspondence between different degrees of tooth misalignment and archwire reduction levels can be expressed as a functional relationship. Alternatively, the correspondence between different degrees of tooth misalignment and archwire reduction levels can be presented as a table.

[0135] like Figures 5a to 5dAs shown, the degree of tooth misalignment at the site of tooth malformation can include, but is not limited to, horizontal misalignment, vertical misalignment, rotational misalignment, and axial misalignment. Taking horizontal misalignment as an example, its definition is as follows: The difference in elevation between the malformed tooth and the corresponding row of the dental arch in the horizontal direction is called horizontal misalignment. Other misalignments are similar and will not be elaborated upon here. The specific correspondence between each misalignment degree and the archwire thinning level is shown in Tables 2 to 5 below.

[0136] Combination Figure 5a The horizontal misalignment shown in Table 2 is a table showing the correspondence between the horizontal misalignment and the archwire thinning grade.

[0137] Table 2

[0138]

[0139] Combination Figure 5b The vertical misalignment shown is illustrated in Table 3 below, which shows the correspondence between vertical misalignment and archwire thinning grade.

[0142] Combination Figure 5c The torsional misalignment shown is corresponding to the torsional misalignment and archwire thinning grade in Table 4 below.

[0146] Table 5

[0147] Axial misalignment Recommended bowwire type for initial wire Recommended follow-up visit cycle Convergence and Twist >50 Fine first-grade silk +2W

[0148] Step ②: When removing the archwire of the initial archwire model, determine the archwire removal level corresponding to the malocclusion value of the tooth at the malformation site, and the initial usage time added per use cycle for the initial archwire model. The initial usage time in this application can be set according to user needs and industry experience, and is not limited here.

[0149] Step 3: Based on the wire unwinding grade, unwind the initial wire model and increase the single-use cycle of the initial wire model according to the increased first usage time.

[0150] As shown in Tables 2 to 5 above, the first additional usage time can be, but is not limited to, +1W or +2W.

[0151] Step 4: Output the initial bow wire model without unwinding the bow wire.

[0152] In this embodiment of the application, depending on the specific archwire unwinding situation, an accurate archwire model of the initial wire can be provided so that the archwire model of the initial wire of the reference scheme can be displayed on the display interface at the end.

[0153] Step ① above can be achieved in several ways:

[0154] In the first method of step ① above, any misalignment degree is selected from the horizontal misalignment degree, vertical misalignment degree, rotational misalignment degree, and axial misalignment degree of the tooth malformation site. Here, any misalignment degree can refer to any of the horizontal, vertical, rotational, and axial misalignment degrees. For example, any misalignment degree can be, but is not limited to, any misalignment degree between the minimum and maximum misalignment degree. Any misalignment degree is also not limited to the minimum misalignment degree. Any misalignment degree is also not limited to the maximum misalignment degree. Furthermore, based on the selected misalignment degree of the tooth malformation site, and according to the corresponding relationship between the tooth misalignment degree and the archwire thinning grade, it is determined whether the initial archwire model needs to be thinned, based on the initial archwire model. Thus, in this method, randomly determining the misalignment degree allows for rapid determination of the archwire thinning status, improving the efficiency of determining the initial archwire model.

[0155] In the second method of step ① above, the maximum misalignment is selected from the horizontal misalignment, vertical misalignment, rotational misalignment, and axial misalignment of the malformed tooth. Furthermore, based on the maximum misalignment of the malformed tooth, and according to the correspondence between the maximum tooth misalignment and the recommended archwire thinning grade, it is determined whether archwire thinning is required for the initial archwire model, based on the initial archwire model.

[0156] For example, this article describes the misalignment of the teeth in various directions, taking the largest horizontal misalignment as an example. For instance, if the horizontal misalignment of the misaligned tooth is 4mm, this is the largest horizontal misalignment, and it is greater than 3mm. In this case, the tooth should be moved one grade down, and it is recommended to extend the follow-up visit interval by 2 weeks.

[0157] In this approach, the maximum degree of misalignment in all directions at the site of tooth malformation is used to represent the most complex misalignment situation. This can cover other misalignments, reduce the treatment time, and thus avoid repeated treatment.

[0158] Combination Figure 2 The leveling process nodes shown are Figure 4 As shown, the above-mentioned tooth alignment parameters include tooth overbite. Tooth overbite reflects overbite, specifically the vertical distance between the upper and lower teeth.

[0159] Correspondingly, in the second embodiment of step 130 above, a) using the overbite condition of the malformed tooth location, based on the correspondence between different overbite conditions and the recommended archwire model of the terminal wire, generate the archwire model of the terminal wire corresponding to the overbite condition value of the malformed tooth location, and the single-use cycle of the archwire model of the terminal wire.

[0160] Different overbite conditions reflect different grades of overbite. Each grade of overbite corresponds to a recommended archwire size for the terminal wire. The larger the overbite, the thicker the recommended terminal wire. The correspondence between different overbite conditions and recommended archwire sizes can be a functional relationship. Alternatively, the correspondence can be presented in a table, as shown in Table Six below:

[0161] Table 6

[0162]

[0163] In this embodiment, the archwire model of the terminal wire can be quickly generated based on the correspondence between different tooth overbite conditions and the recommended archwire model, as well as the single-use cycle of the archwire model. This improves the efficiency and accuracy of terminal wire determination.

[0164] Based on the above-mentioned overbite situation, the following can be used: <1> to <4> The steps involve adjusting or determining the archwire type of the terminal wire.

[0165] The above-mentioned tooth leveling parameters also include tooth coverage; tooth coverage is used to determine overjet overjet, specifically the horizontal distance by which the anterior teeth protrude beyond the lower teeth.

[0166] Different overjet patterns reflect different grades of tooth coverage. Each grade of overjet pattern corresponds to specific adjustments for the recommended archwire size for the terminal wire. These adjustments include specific wire insertion details, such as whether to use a thicker grade one wire or a thicker grade two wire. The correspondence between different overjet patterns and the recommended archwire size for the terminal wire can be a functional relationship. Alternatively, the correspondence can be presented in a table, as shown in Table 7 below.

[0167] Table 7

[0168]

[0169] <1> 1. Analyze the tooth coverage of the malformed area, and based on the different tooth coverage conditions, determine the correspondence between the recommended archwire type and the terminal wire type. Then, based on the recommended archwire type, determine whether to adjust the terminal wire type and the single-use cycle for adjusting the terminal wire type.

[0170] The single-use cycle for adjusting the bowwire type of the terminal wire mentioned above corresponds to whether or not wire is fed. In the embodiments of this application, the single-use cycle for adjusting the bowwire type of the initial wire includes increasing the single-use cycle of the bowwire type of the initial wire.

[0171] For example, if the coverage is Grade I deep coverage, the archwire type of the terminal wire remains unchanged. If the coverage is Grade II deep coverage, a thicker archwire should be selected for the terminal wire, and it is recommended to increase the follow-up visit interval by 2 weeks.

[0172] <2> Given a determined archwire model for adjusting the terminal wire, the adjustment data corresponding to the degree of tooth misalignment at the site of tooth malformation, and the additional second usage duration per single usage cycle for the chosen archwire model, are determined. This second usage duration can be set based on user needs and industry experience, and is not limited here.

[0173] <3> Based on the adjustment data, the archwire model of the terminal wire is adjusted, and the single-use cycle of the archwire model of the terminal wire is increased according to the increased second usage time.

[0174] <4> Without adjusting the bow wire type of the terminal wire, output the bow wire type of the terminal wire and the single-use cycle of the bow wire type of the terminal wire.

[0175] Correspondingly, combined Figure 1 The aforementioned 140 may further include displaying the single-use cycle of the adjusted terminal wire and the added terminal wire archwire model of the reference scheme on the display interface.

[0176] In this embodiment, by combining different tooth overbite conditions with tooth coverage conditions, the actual situation of the malformed tooth location can be better reflected. The archwire type of the terminal wire and the single-use cycle of the archwire type of the terminal wire can be adjusted based on the tooth coverage conditions. This improves the accuracy of terminal wire determination.

[0177] The first and second embodiments of step 130 above can be executed individually or in combination. When the two embodiments are implemented in combination, the execution order is not important.

[0178] When there is no need for tooth extraction, the output of tooth movement after extraction is zero, and the "Extraction Required?" option is filled with "No", or the orthodontic reference information in the reference plan does not display information related to tooth extraction. When tooth extraction is required, and there is a gap between the two sides of the extracted tooth after extraction, the gap needs to be closed, as detailed below.

[0179] Combination Figure 2 The process nodes for leveling and closing gaps are shown. The above-mentioned parameters to be corrected include gap closing parameters; gap closing parameters include the amount of tooth movement after extraction; the amount of tooth movement after extraction is the average of the difference between the bilateral extraction gaps and the crowding degree. That is, the horizontal tooth movement amount = (bilateral extraction gaps - crowding degree) / 2. Bilateral extraction gaps refer to the gap between the two sides of the extracted tooth.

[0180] The above methods also include: outputting the amount of tooth movement during extraction.

[0181] Based on the amount of tooth movement after extraction, a method for closing gaps between the extracted teeth and the remaining teeth (excluding the extracted teeth) is generated, along with the anchorage strength and the archwire type to be recommended. This allows the recommended archwire on the posterior molars to lock relative to its corresponding bracket, while the recommended archwire on the anterior teeth moves relative to its corresponding bracket, thus controlling the locking anchorage and closing gaps for the remaining teeth. The recommended archwire can be a transition wire or a terminal wire. In this way, the archwire on the posterior molars is locked to the bracket, preventing movement of the posterior molars, while the anterior molars move relative to the bracket using the archwire. This achieves strong anchorage.

[0182] Furthermore, based on the amount of tooth movement after extraction and the orthodontic tools, the strength of the anchorage of the corresponding row of teeth to the remaining teeth (excluding the extracted teeth) is generated; based on the strength of the anchorage, and according to the correspondence between the strength of the anchorage and the gap closing method and the anti-lock anchorage control, the gap closing method and anti-lock anchorage of the tooth deformity site are determined and output.

[0183] Correspondingly, combined Figure 1The aforementioned 140 may further include displaying on the display interface the amount of tooth movement for extraction in the reference scheme, the method of closing the gap, the strength of the anchorage, and the archwire type of the recommended wire.

[0184] The strength of the aforementioned anchorage can be categorized into strong anchorage, medium anchorage, and weak anchorage.

[0185] For example, if the front teeth move backward while the back teeth (also called molars) remain stationary, this is called strong anchorage. If the molars move by 50% and the front teeth by 50%, or if the molars move by 40% and the front teeth by 60%, this is called moderate anchorage. If the back molars move significantly, such as 60% and the front molars by 40%, or even more, then anchorage is lost, and this is called weak anchorage.

[0186] The correspondence between the strength of the above-mentioned bracing and the closing gap method and the locking bracing control can be a functional relationship between the strength of the bracing and the closing gap method and the locking bracing control, or it can be a table showing the correspondence between the strength of the bracing and the closing gap method and the locking bracing control, as shown in Table 8 below:

[0187] Table 8

[0188] Vector support Closing gap method Lockout support control Weak support One-step method More than just locks Central support Two-step method After arranging and leveling Strong support Two-step method First time

[0189] The above-mentioned methods for closing gaps may include, but are not limited to, one-step and two-step methods. The timing of movement for these gap-closing methods is after leveling is completed. Specific movement methods are shown in Table 9 below:

[0190] Table 9

[0191]

[0192] The above times are the movement time after the wire replacement is completed 4 weeks and the leveling is finished. The recommended follow-up period for the transition wire is 4 weeks longer.

[0193] The above represents the movement speed of a 0.016x0.025 SS (square bowwire) of size 5.

[0194] If it is a No. 6 square bow wire 0.019x0.025 SS, due to friction and other reasons, add 1W of time for every 1mm.

[0195] In this embodiment, since strong bracing is used, the strength of the bracing in the reference scheme is displayed. Of course, for other structures, the corresponding strength can be displayed in the strength of the bracing in the reference scheme according to the bracing situation of its connection, and the corresponding closing gap method and locking bracing control situation are not limited here.

[0196] Combination Figure 2The fine-tuning process nodes shown adjust the torque of the terminal wire as follows: the parameter information to be corrected includes the torque adjustment parameter; the torque adjustment parameter includes the adjustment amount of the torque of the terminal wire;

[0197] The above method also includes: adjusting the torque of generating the terminal filament and the adjustment time period, as shown in Table 10 below.

[0198] Table 10

[0199]

[0200] Correspondingly, combined Figure 1 The aforementioned 140 may further include displaying the torque adjustment amount and adjustment time period of the reference scheme on the display interface. Thus, compared to the square bowwire in related technologies, after twisting, it has a twist angle when engaging with the square groove. In this embodiment, the bolt engages with the bowwire, causing the bowwire to abut against the bottom of the square groove, enabling fine adjustments to torque and angle.

[0201] Combination Figures 1 to 2 As shown in Tables 1 to 10 above, the example displays the correction reference information of the reference scheme on the display interface as follows: Figure 6 Table 11 is shown above. Of course, the above... Figure 6 The correction reference information for the reference schemes shown in Table 11 is for illustrative purposes only and is not intended to be limiting.

[0202] In this embodiment, the precise orthodontic correction, gentle force, and smooth archwire shape ensure safety. Furthermore, it promotes dental and periodontal health, prevents root resorption, and reduces patient discomfort. Simultaneously, it requires less alignment force at the start, less friction during movement, and less adjustment force at the end. In addition, this embodiment not only simplifies the process by reducing the number of archwire types and replacements, but also allows for faster three-dimensional alignment with a light-force, fine-square archwire. The low frictional resistance between the light-force, fine-square archwire and the grooves allows for faster movement. Furthermore, it enables efficient alignment in the early stages of orthodontic alignment, efficient tooth movement in the middle stages, and efficient data expression through fine-tuning in the later stages, resulting in greater efficiency.
