Description

Technical Field

[0001] The present application relates to the technical field of orthodontic correction, and in particular to an orthodontic correction auxiliary device, an orthodontic correction device and a method. Background Art

[0002] Orthodontic treatment technology has developed rapidly in recent years, especially in improving correction efficiency and comfort. Traditional orthodontic methods mainly rely on metal brackets and archwire systems. Although they can achieve certain correction effects, in some complex cases, such as insufficient control of posterior teeth anchorage, traditional methods often fail to achieve ideal correction results. In addition, with the application of digital technology, orthodontic treatment methods are also being continuously optimized. 3D printing technology and customized braces have gradually become mainstream, improving patient comfort and correction effects.

[0003] In existing orthodontic treatment technologies, in order to enhance the control ability of posterior teeth support, the commonly used methods include the use of metal brackets, archwires, and additional support devices. Specifically, the commonly used methods are: 1) using high-rigidity archwires and brackets to maintain the stability of the posterior teeth by applying greater force; 2) installing additional support pins or micro-implants on the posterior teeth to provide stronger support force; 3) using auxiliary devices such as elastic rubber bands or springs to help maintain the position of the posterior teeth. These methods can enhance the support ability of the posterior teeth to a certain extent, but there are also some limitations.

[0004] However, the above methods still have some defects in practical applications. For example, the use of high-rigidity archwires and brackets may cause discomfort to patients and easily cause problems such as gingivitis during long-term use. Although additional anchorage pins or micro-implants can provide stronger support forces, their installation and maintenance are relatively complicated, which increases the burden on patients. In addition, although auxiliary devices such as elastic rubber bands or springs are easy to operate, they are insufficient in stability and can easily lead to poor correction effects. Therefore, how to effectively enhance the anchorage control ability of posterior teeth while ensuring patient comfort is still a technical problem that needs to be solved in the field of orthodontic correction. Summary of the invention

[0005] The first purpose of the present application is to provide an orthodontic correction auxiliary device.

[0006] The above technical objectives of the present application are achieved through the following technical solutions: an orthodontic correction auxiliary device, comprising: A collar, used to wrap around a plurality of teeth as a whole to restrict movement of the plurality of teeth; The positioning block is arranged on the collar and is used to cooperate with the dental brace.

[0007] By adopting the above technical solution, the ring can wrap several teeth as a whole to limit their movement, thereby effectively enhancing the control ability of the posterior teeth anchorage, keeping the posterior teeth relatively stable during orthodontic correction, and providing more reliable support for the movement of the anterior teeth; the positioning block cooperates with the braces, and can accurately position when the braces are worn and can transmit the correction force to a certain extent, and the cooperation of the two is conducive to achieving more personalized and precise orthodontic correction and improving the orthodontic effect. At the same time, under the premise of ensuring the correction effect, it can improve the patient's comfort to a certain extent, reduce the patient's burden, and better meet the orthodontic needs.

[0008] Optionally, the collar is an annular structure, so the inner diameter of the collar fits tightly with the crown portions of several teeth.

[0009] By adopting the above technical solution, the ring with an annular structure and an inner diameter that closely matches the crowns of several teeth can fit closely to the crowns of the posterior teeth, limiting the unnecessary movement of the posterior teeth to the greatest extent, ensuring that the posterior teeth maintain a stable position during orthodontic treatment, and providing a solid support foundation for the entire treatment process. This close fit can also reduce the shaking or displacement of the ring on the teeth, improve the accuracy and predictability of the correction, and enable the orthodontic correction force to act more effectively on the target teeth, thereby improving the effect of orthodontic treatment. It also helps to reduce the patient's oral discomfort that may be caused by the device not fitting well, and optimize the patient's correction experience.

[0010] Optionally, the ring is made of metal material.

[0011] By adopting the above technical solution, the metal material has good strength and stability, can provide reliable and lasting wrapping and limiting effect for the posterior teeth, effectively enhance the control ability of the posterior teeth anchorage, ensure that the posterior teeth remain stable during orthodontic treatment, and create favorable conditions for the precise movement of the anterior teeth. It is durable and can withstand various forces in the orthodontic process without being easily deformed or damaged, ensuring the long-term effectiveness of the correction device. At the same time, metal materials are relatively easy to process and shape, making it easy to produce a ring structure that fits tightly with the crowns of the posterior teeth, which is beneficial to improve the accuracy of the correction device, thereby improving the overall orthodontic effect, and to a certain extent can adapt to the morphological differences of the posterior teeth of different patients, meeting the diverse orthodontic treatment needs.

[0012] Optionally, the positioning block is a convex block structure, the number of the positioning block is at least one, and the positioning blocks are evenly distributed on the outer surface of the ring.

[0013] By adopting the above technical solution, the positioning block of the convex block structure is easy to interact with the groove on the braces. The design of at least one and evenly distributed on the outer surface of the ring allows the braces to accurately match the ring from multiple directions and positions when worn, ensuring the stability and accuracy of braces wearing. This even distribution method is conducive to evenly dispersing the correction force applied by the braces, avoiding excessive local force causing adverse effects on the teeth, and at the same time can more comprehensively control the overall movement trend of the posterior teeth, so that the posterior teeth remain stable during the orthodontic process and move in a predetermined direction, effectively improving the control ability of the posterior teeth support, thereby improving the overall orthodontic correction effect, making tooth movement more scientific and reasonable, and helping to achieve ideal tooth arrangement.

[0014] Optionally, the collar and the positioning block are integrally formed.

[0015] By adopting the above technical solution, the structural integrity and stability of the orthodontic auxiliary device can be significantly enhanced through the one-piece molding design of the collar and the positioning block. The one-piece molding avoids connection gaps or looseness between components, reduces the risk of device failure due to connection problems during use, and ensures that the auxiliary device can work reliably for a long time in the complex environment of the oral cavity. This structural design makes the connection between the positioning block and the collar more secure, and when the braces and the positioning block cooperate to apply the correction force, the force can be transmitted more effectively, ensuring the accurate transmission and uniform distribution of the correction force, which is conducive to more precise control of tooth movement. At the same time, the one-piece molding also simplifies the production and manufacturing process, reduces production costs, improves production efficiency, facilitates large-scale production and promotion, and provides strong support for the popularization of orthodontic correction technology, and improves the effect and feasibility of orthodontic correction as a whole.

[0016] Optionally, a connecting piece is provided on the collar for spacing and fixing adjacent teeth among the plurality of teeth.

[0017] By adopting the above technical solution, the connector can accurately control the distance between adjacent teeth among several teeth, ensuring that the posterior teeth remain stable as a whole and the positional relationship is in line with expectations during the orthodontic process, providing a more accurate and reliable support basis for the movement of the anterior teeth, making the tooth movement more orderly and efficient, and improving the accuracy and effectiveness of orthodontic treatment. On the other hand, this fixing method helps to evenly disperse the force under the action of the correction force, avoiding displacement or damage caused by excessive force on a single posterior tooth, and at the same time better adapting to the differences in the spacing between the posterior teeth of different patients, further enhancing the personalization and adaptability of the entire orthodontic correction device, improving the comfort and safety of patients during the orthodontic process, and promoting the smooth progress of orthodontic treatment.

[0018] The second purpose of this application is to provide an orthodontic correction device.

[0019] The above technical purpose of the present application is achieved through the following technical solutions: an orthodontic correction device, including the above-mentioned orthodontic correction auxiliary device, and also including braces, on which a groove matching the positioning block is provided.

[0020] By adopting the above technical solutions, the collar in the orthodontic auxiliary device effectively limits the movement of the posterior teeth and provides a stable support for the movement of the anterior teeth. Combined with the groove design that matches the braces and the positioning block, precise tooth movement control is achieved to ensure that the teeth move in an orderly manner according to the predetermined plan, thereby improving the accuracy of orthodontic treatment. The precise design can reduce the number of tooth adjustments, improve the efficiency of correction, shorten the treatment cycle, and reduce patient costs. The tightly fitting collar and stable braces enhance patient comfort, reduce foreign body sensation and the risk of mucosal damage, and improve compliance. The personalized design based on individual oral conditions meets diverse needs, and the matching of the groove and the positioning block ensures the stability of the correction force, stabilizes the trend of tooth movement, and enhances the predictability and stability of the orthodontic effect.

[0021] The third purpose of this application is to provide an orthodontic correction method.

[0022] The above technical objectives of the present application are achieved through the following technical solutions: an orthodontic correction method, comprising: Perform a comprehensive oral examination to determine the position and condition of the teeth that need correction. Then use oral instruments to create a certain gap between the first and second posterior teeth. The gap is 0.3mm-0.7mm. Then use oral scanning equipment to make a model of the first tooth. A collar and a positioning block are made based on the first tooth model, and the collar with the positioning block is put on a number of teeth, the collar fits tightly to the crown surface of the tooth, the positioning block is in the correct position, and then the collar and the tooth are scanned again to obtain a second tooth model with the collar; The model data of the second tooth model is imported into the orthodontic design software, and the model data is adjusted according to the specific orthodontic needs and oral conditions. After the adjustment is completed, the third tooth model is generated; The model data of the third tooth model is transmitted to the braces production equipment, and the braces matching the third tooth model are produced by using digital manufacturing technology, and the braces are worn in the patient's mouth.

[0023] By adopting the above technical solutions, a comprehensive oral examination lays the foundation for precise correction, accurately deduces the gap between the posterior teeth and makes a model, which can better adapt to the individual's dental conditions. Based on the model, the ring and positioning block are made and a second scan is performed to obtain a more accurate model, and then the final model is generated through software adjustment to produce braces, which achieves highly personalized customization. The entire process is closely combined with the actual oral conditions of the patient. Digital manufacturing technology ensures that the braces are highly matched with the teeth, effectively improving the accuracy and effectiveness of correction. At the same time, this systematic approach helps to enhance the control ability of posterior tooth support, make tooth movement more scientific and orderly, improve orthodontic effects, and can reduce patient discomfort to a certain extent, optimize the correction experience, and promote orthodontic treatment in a more accurate, efficient and comfortable direction.

[0024] Optionally, the steps of transmitting the model data of the third tooth model to a braces production device, using digital manufacturing technology to produce a braces matching the third tooth model, and wearing the braces in the patient's mouth include: Obtaining model data of the third tooth model and constructing a corresponding three-dimensional model of the braces; Based on the model data of the third tooth model and the model data of the three-dimensional model of the braces, in the three-dimensional model environment, simulating the effect of wearing the three-dimensional model of the braces on the third tooth model, and determining the positional relationship between the groove on the braces and the positioning block; Use software measurement tools to determine whether there is a misalignment setting between the groove and the positioning block. If there is a misalignment setting, further measure the misalignment distance of the misalignment setting; Compare the measured misalignment distance with the preset reasonable range; If the misalignment distance is within a reasonable range, it is confirmed that the braces meet the requirements; If the misalignment distance is not within a reasonable range, the braces need to be adjusted or remade.

[0025] By adopting the above technical solutions and using digital model construction and simulation, the positional relationship between the braces groove and the positioning block can be accurately determined in a virtual environment, and possible problems can be predicted and detected in advance. Accurately determine the misalignment of the groove and the positioning block, measure the misalignment distance, and compare it with the preset range, effectively ensuring the precise matching of the braces and orthodontic auxiliary devices. This not only ensures that the braces can perfectly cooperate with the teeth and auxiliary devices when worn, achieve ideal correction force transmission, enhance the control ability of posterior teeth support, and improve orthodontic effects, but also can promptly discover and correct problems in the production stage, avoid unqualified products from being used on patients, reduce the trouble of patients having to repeatedly adjust due to inappropriate braces, improve the accuracy, stability and efficiency of the correction process, and further improve the patient's correction experience and treatment success rate.

[0026] Optionally, the method further includes: Obtaining the current dental model and the current orthodontic appliance model of the patient at the current treatment stage; storing model data of a current tooth model and model data of a current orthodontic appliance model; Based on the current tooth model and the current orthodontic appliance model, determining the positional relationship between the groove and the positioning block in the current orthodontic appliance model; Based on the current tooth model, the adjustment scheme of grooves and positioning blocks is automatically calculated to adapt to the changes of teeth.

[0027] By adopting the above technical solutions, the status of the patient's teeth and orthodontic devices can be tracked in real time during the orthodontic treatment process. Storing the current tooth model and orthodontic device model data is convenient for review and analysis, and determining the position relationship between the groove and the positioning block based on the model can accurately grasp the current treatment situation. Automatically calculating the adjustment plan based on tooth changes can timely adapt to the dynamic changes of teeth during the treatment process, continuously optimize the transmission and control of the correction force, always maintain effective control of the posterior tooth anchorage, and ensure that orthodontic treatment is always moving towards the expected goal. This not only improves the accuracy and adaptability of the correction process, but also provides doctors with a more scientific decision-making basis, timely adjusts treatment strategies, effectively reduces treatment time, improves treatment effects, and at the same time enhances patients' confidence in treatment, making orthodontic treatment more intelligent, personalized, and efficient.

[0028] In summary, this application has at least the following beneficial effects: 1. By wrapping several teeth as a whole in the ring, the movement of the two posterior teeth is restricted, thereby effectively enhancing the anchorage control ability of the posterior teeth and avoiding the problem of easy movement of the posterior teeth in traditional methods; 2. The positioning block on the collar cooperates with the groove on the braces, which can exert precise force during the fitting process, ensuring that the front teeth move backward without affecting the stability of the back teeth, thus improving the orthodontic effect; 3. The application of digital manufacturing technology makes the entire orthodontic correction process more accurate and efficient, reduces human errors, and improves patient comfort and treatment effects.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] In this embodiment, refer to Figure 1-2 An orthodontic correction auxiliary device comprises a collar 1 and a positioning block 2. The collar 1 is used to wrap a plurality of teeth as a whole, preferably the plurality of teeth are two posterior teeth, namely a first posterior tooth and a second posterior tooth, to limit the movement of the two posterior teeth. The positioning block 2 is arranged on the collar 1 and is used to cooperate with the braces so that the braces can accurately apply the correction force.

[0033] Specifically, the collar 1 is an annular structure, and the inner diameter is closely adapted to the crown part of the first posterior tooth and the second posterior tooth, ensuring that the collar 1 can be firmly fixed on the teeth. The collar 1 is made of metal material, has high strength and corrosion resistance, and can maintain a stable shape for a long time. The positioning block 2 is a convex block structure, and there is at least one in number. Preferably, there are 4 positioning blocks 2, which are evenly distributed on the outer surface of the collar 1, so that it can be ensured that the positioning block 2 can cooperate with the groove of the braces in all directions. The positioning block 2 can be made of stainless steel or titanium alloy, both of which have good biocompatibility and mechanical properties. The positioning block 2 and the collar 1 can be integrally formed by welding or casting to ensure that the connection between the two is stable and reliable. In addition, the shape of the positioning block 2 can be designed to be circular, square or other polygonal to adapt to the grooves of the braces of different shapes.

[0034] The combined design of the collar 1 and the positioning block 2 effectively enhances the control ability of the posterior teeth. The collar 1 wraps the two posterior teeth together, making them less likely to move, thereby providing stable support for the posterior movement of the anterior teeth. At the same time, the positioning block 2 cooperates with the groove of the braces to ensure the directionality and accuracy of the braces when applying the correction force, avoiding poor correction effect caused by the displacement of the braces.

[0035] The inner diameter of the collar 1 can be customized according to the tooth size of different patients to ensure that the collar 1 can fit the crown surface perfectly. The height and width of the positioning block 2 can also be adjusted according to the specific situation to adapt to different types of brace grooves. For example, for braces with larger calibers, the height of the positioning block 2 can be increased to ensure a better fit.

[0036] The implementation principle of this embodiment is: the two posterior teeth are wrapped together by the collar 1 to limit their movement, providing a stable support point for the posterior movement of the anterior teeth. The positioning block 2 cooperates with the groove of the brace to ensure the accuracy and stability of the brace when applying the correction force. This design not only improves the effect of orthodontic treatment, but also reduces the discomfort of the patient during the correction process.

[0037] Reference Figure 3 , in another embodiment, the difference between this embodiment and the above-mentioned embodiment is that: a connecting member 3 is provided on the ferrule 1 for spacing and fixing the first posterior tooth and the second posterior tooth.

[0038] Specifically, it is preferred that the connecting member 3 and the ferrule 1 are integrally formed. The two ends of the connecting member 3 are firmly connected to the parts of the ferrule 1 corresponding to wrapping the first posterior tooth and the second posterior tooth, so that the whole ferrule 1 presents a structure similar to the Chinese character 'Ri' (day). The length of the connecting member 3 can be customized or adjusted according to the ideal distance between the first posterior tooth and the second posterior tooth of different patients to ensure that the two posterior teeth can be accurately spaced and fixed.

[0039] When the ferrule 1 is worn on the first posterior tooth and the second posterior tooth, the connecting member 3 is located between the two posterior teeth to precisely control the distance between them. During orthodontic treatment, the connecting member 3 can withstand forces from different directions and prevent the first posterior tooth and the second posterior tooth from moving unnecessarily in the horizontal or vertical directions. For example, when the patient chews food or speaks, the connecting member 3 can effectively resist the squeezing force between the teeth and keep the position of the posterior teeth stable.

[0040] The length of the connecting member 3 is customized according to the specific oral conditions of the patient. Before manufacturing the orthodontic appliance, the doctor will determine the optimal distance between the first posterior tooth and the second posterior tooth through oral scanning and model analysis. Then, a connecting member 3 with a suitable length is selected according to this distance to ensure that it can effectively fix the posterior teeth without affecting the normal oral function of the patient.

[0041] The embodiment of the present application provides an orthodontic appliance, including the above-mentioned orthodontic auxiliary device, and further including a dental brace, and a groove matching the positioning block 2 is provided on the dental brace.

[0042] Specifically, the preferred braces are transparent braces without brackets. Transparent braces without brackets are generally made of transparent polymer materials, such as thermoplastic polyurethane (TPU), polyethylene terephthalate-1,4-cyclohexanedimethanol (PETG), etc. The bracketless design eliminates protrusions in the mouth like traditional metal brackets, reduces irritation and friction to the oral mucosa, effectively reduces the incidence of oral discomfort symptoms such as oral ulcers and swollen gums, and improves the comfort of patients when wearing them. From the perspective of mechanical properties, although bracketless braces do not have a directly visible rigid connection between metal brackets and archwires, they are precisely designed based on the patient's tooth model using digital manufacturing technology. Through software simulation and analysis of the force requirements of the patient's teeth, the thickness and material elastic modulus of different parts of the braces are set differently, so as to achieve precise force application to the teeth. For example, for tooth areas that require greater corrective force, the corresponding braces will be appropriately thickened and materials with a higher elastic modulus will be selected to ensure that sufficient corrective force can be applied to promote tooth movement; for teeth that only need to maintain their current position or make fine adjustments, thinner and moderately elastic materials will be used to avoid excessive force.

[0043] In cooperation with the orthodontic auxiliary device, the groove on the bracketless braces is tightly fitted with the positioning block 2. The depth, width of the groove and the shape and size of the positioning block 2 are carefully designed to ensure that the braces can stably work with the ring 1 during the correction process. When the patient wears the braces, the braces use the close connection between the groove and the positioning block 2 to accurately transmit the correction force to the ring 1 and the posterior teeth, guiding the posterior teeth to remain stable while allowing the front teeth to move in an orderly manner according to the predetermined correction plan. Moreover, the bracketless braces are easy for patients to take off and put on by themselves, which is not only convenient for patients' daily oral cleaning, can effectively remove food residues and maintain oral hygiene, but also makes it more convenient for patients to take off the braces when eating or in special occasions, further improving the convenience of patients' use, and comprehensively improving the effect, comfort and compliance of orthodontic correction.

[0044] The ring 1 is made of metal material and has an annular structure, and its inner diameter is tightly fitted with the crown part of the first posterior tooth and the second posterior tooth. This tight fit is based on the good plasticity and stability of the metal, so that the ring 1 can firmly wrap the two posterior teeth to form a relatively stable whole. The rigidity of the metal can resist the various forces exerted on the posterior teeth during orthodontic correction, prevent the posterior teeth from being easily displaced, thereby effectively limiting the movement of the first posterior teeth and the second posterior teeth, and providing a stable posterior tooth support foundation for the entire orthodontic correction. For example, under the influence of the complex chewing force of the oral cavity and the correction force applied by the braces, the ring 1, by virtue of its metal material and tightly wrapped structure, keeps the position of the posterior teeth relatively fixed, so that the orthodontic correction force can act more accurately on other teeth that need to be moved, such as the front teeth.

[0045] The positioning block 2 is a convex block structure, there is at least one of them and they are evenly distributed on the outer surface of the collar 1. The positioning block 2 is integrally formed with the collar 1, and this integrally formed structure ensures the stability of the connection between the positioning block 2 and the collar 1. When the braces are worn, the grooves on the braces interact with the positioning block 2. The evenly distributed positioning blocks 2 allow the braces to accurately match the collar 1 in all directions, ensuring that the correction force applied by the braces can be evenly transmitted to the collar 1 and the posterior teeth through the positioning blocks 2. For example, during the correction process, the pressure exerted by the braces on the positioning block 2 will be converted into a control and guiding force on the posterior teeth. Since the positioning blocks 2 are evenly distributed, the force on the posterior teeth is evenly distributed, avoiding abnormal tooth movement or damage caused by excessive local force.

[0046] The braces are provided with grooves matching the positioning block 2. During the wearing process of the braces, the braces are engaged with the positioning block through the grooves. As the braces are gradually put into place, the grooves begin to contact and interact with the positioning block 2. The braces are transmitted to the collar 1 and the posterior teeth through the positioning block 2, achieving precise control of the posterior teeth anchorage, while also guiding the front teeth and other teeth to move in a predetermined direction.

[0047] The present application provides an orthodontic correction method, referring to Figure 4 , the main process of the method is described as follows: S1: Perform a comprehensive oral examination to determine the position and condition of the teeth that need correction. Then use oral instruments to create a certain gap between the first and second posterior teeth. The gap is 0.3mm-0.7mm. Then use oral scanning equipment to make the first tooth model. Among them, high-precision optical scanning technology is used to scan the patient's oral cavity in all directions. This scanning technology can clearly capture the shape, position, color of teeth, and related information of gums and jaws, with a resolution of up to micron level, ensuring the acquisition of extremely detailed oral data. At the same time, the automated diagnosis system analyzes the scanned data in real time, using the built-in oral database and intelligent algorithms to accurately determine the health status, arrangement and occlusion of the teeth, and accurately locate the position of the teeth that need correction, especially focusing on the first and second posterior teeth.

[0048] According to the diagnosis results, the automated treatment planning software automatically generates a personalized treatment plan to determine the size of the gap between the first and second posterior teeth. The gap value is accurately calculated by an algorithm based on multiple factors such as the patient's tooth crowding and occlusal requirements, and the range is strictly controlled between 0.3mm-0.7mm. Subsequently, according to the instructions, the appropriate orthodontic device (such as a tooth-splitting spring that automatically adjusts the force and direction) is selected, and the first and second posterior teeth are pushed out to a predetermined gap in a specific direction with precise force and direction. The enamel on the teeth can also be taken into account to obtain the predetermined gap by removing the enamel on the adjacent surfaces of the two teeth. During the entire process, pressure and position sensors are installed in the patient's mouth to monitor the movement of the teeth in real time to ensure that the operation is safe and in line with expectations. After the operation is completed, the mouth is scanned again to obtain accurate first tooth model data, which is automatically transmitted to the central data processing system.

[0049] S2: Based on the first tooth model, a ring 1 and a positioning block 2 are made, and the ring 1 with the positioning block 2 is inserted into the first posterior tooth and the second posterior tooth, the ring 1 is tightly fitted to the crown surface of the tooth, and the positioning block 2 is correctly positioned, and then the ring 1 and the tooth are scanned again to obtain a second tooth model with the ring 1; Among them, after receiving the data of the first tooth model, the central data processing system transmits it to the automatic design software for orthodontic auxiliary devices. Based on advanced artificial intelligence algorithms and mechanical simulation technology, the software automatically designs the most optimized structure of the collar 1 and positioning block 2 according to the shape and position of the posterior teeth in the first tooth model and the principle of orthodontic mechanics. The inner diameter of the collar 1 is accurately calculated by the algorithm to ensure that the fit with the crown of the posterior teeth reaches the highest standard. The shape, number and distribution position of the positioning block 2 are also determined through simulation analysis to ensure that the best correction force transmission effect can be achieved when combined with the braces.

[0050] After the design is completed, the data is sent to the metal 3D printing automated production line. On the production line, the high-precision metal 3D printer selects metal materials that meet biocompatibility standards (such as medical titanium alloys) based on the design data and prints according to the preset process parameters. During the printing process, the real-time monitoring system uses laser measurement and image recognition technology to monitor the molding quality of the collar 1 and the positioning block 2 to ensure that the dimensional accuracy is controlled within a very small error range (for example, ±0.05mm) and the surface roughness meets the smooth standard. After printing is completed, the automatic sorting and cleaning equipment processes the product to remove excess materials and support structures.

[0051] Then, according to the pre-set program and oral model data, the ring 1 with the positioning block 2 is accurately inserted into the first and second posterior teeth in the patient's mouth. During the insertion process, a micro force sensor and a visual recognition system are used to ensure that the ring 1 fits tightly against the crown surface of the tooth and the positioning block 2 is accurately positioned. After the ring 1 is worn, the ring 1 and the teeth are scanned again to obtain the second tooth model data with the ring 1 and transmit it back to the central data processing system.

[0052] S3: importing the model data of the second tooth model into the orthodontic design software, adjusting it according to the specific orthodontic needs and oral conditions, and generating the third tooth model after the adjustment is completed; Among them, the central data processing system imports the data of the second tooth model with the ring 1 into the orthodontic design intelligent software. The software integrates rich orthodontic clinical experience data and advanced biomechanical simulation engines. Doctors enter key parameters in the software through the remote operation interface according to the patient's specific orthodontic goals (such as improving facial aesthetics, optimizing occlusal function, etc.). The software automatically adjusts the tooth model comprehensively based on these parameters and the actual oral condition using complex algorithms. During the adjustment process, the software simulates various situations after tooth movement in real time, including the impact on adjacent teeth, gums and jaws, and presents it to the doctor in a three-dimensional visual form. Doctors can further optimize and adjust the parameters based on the simulation results until the ideal orthodontic design is achieved.

[0053] After the adjustment is completed, the software automatically generates the third tooth model data and stores it in the central data server, while marking the patient's personal information and treatment progress, providing complete data support for subsequent braces production and tracking.

[0054] S4: The model data of the third tooth model is transmitted to the braces production equipment, and the braces matching the third tooth model are produced by using digital manufacturing technology, and the braces are worn in the patient's mouth.

[0055] Among them, the central data processing system transmits the third tooth model data to the automatic production workshop of braces. Large-scale digital manufacturing equipment in the production workshop (such as multi-nozzle light-curing 3D printers or high-speed hot pressing molding machines) select polymer materials with excellent elasticity and biocompatibility (such as polycarbonate) according to the data, and produce braces according to the preset process procedures. During the production process, the quality control system uses machine vision and physical performance testing equipment to monitor and automatically adjust the dimensional accuracy, surface quality and mechanical properties of braces in real time to ensure that each brace meets high quality standards.

[0056] After the braces are automatically packaged and marked, they are delivered to the patients together with the wearing instruction video and electronic instruction documents. Patients wear the braces at home according to the detailed instructions in the video and documents. When wearing them, patients can use devices such as mobile phones or smart mirrors to assist in observing the fit of the braces with the teeth through augmented reality (AR) technology to ensure that the grooves on the braces and the positioning blocks 2 on the ring 1 are accurately set. At the same time, patients can communicate with doctors in real time through the online consultation platform and feedback problems during the wearing process. Doctors provide remote guidance and adjustment suggestions based on the feedback to ensure the smooth progress of the orthodontic correction process. Throughout the process, the patient's wearing data and feedback information are automatically recorded and transmitted back to the central data processing system for doctors to track and evaluate.

[0057] Specifically, in some possible embodiments, the steps of transmitting the model data of the third tooth model to a braces production device, using digital manufacturing technology to produce a braces matching the third tooth model, and wearing the braces in the patient's mouth include: Obtaining model data of the third tooth model and constructing a corresponding three-dimensional model of the braces; Based on the model data of the third tooth model and the model data of the braces three-dimensional model, in the three-dimensional model environment, simulate the effect of wearing the braces three-dimensional model on the third tooth model, and determine the positional relationship between the groove on the braces and the positioning block 2; Use software measurement tools to determine whether there is a misalignment setting between the groove and the positioning block 2. If there is a misalignment setting, further measure the misalignment distance of the misalignment setting; Compare the measured misalignment distance with the preset reasonable range; If the misalignment distance is within a reasonable range, it is confirmed that the braces meet the requirements; If the misalignment distance is not within a reasonable range, the braces need to be adjusted or remade.

[0058] Among them, after receiving the model data of the third tooth model, it is imported into the professional braces design software. The software first parses and preprocesses the data to identify the key features in the tooth model, such as the contour, height, width, curvature of the teeth, and the position of the ring 1 and the positioning block 2. Then, according to the preset braces design template and parameters, the software automatically generates an initial braces 3D model. The shape of this model matches the third tooth model, and it initially has the basic shape of the braces, including the overall contour of the braces, the inner surface that fits the teeth, and the texture of the outer surface. During the construction process, the software uses advanced geometric modeling algorithms to ensure the accuracy and smoothness of the braces model, laying the foundation for subsequent simulation and adjustment.

[0059] Using the simulation function of the software, the generated three-dimensional model of the braces and the third tooth model are simulated to wear in a virtual three-dimensional model environment. The software simulates the movement trajectory of the braces and the interaction with the tooth model during actual wearing through precise collision detection and physical simulation algorithms. In this process, the focus is on the contact and fit between the groove on the braces and the positioning block 2. The software will calculate and record the relative position relationship between the groove and the positioning block 2 at different wearing stages, including their initial contact point, contact angle, and position changes as the braces are gradually put into place. Through multiple simulated wearing, analysis is performed from different angles and directions to determine the optimal position relationship between the groove and the positioning block 2 under the ideal wearing state, to ensure that the two can accurately match and achieve effective correction force transmission.

[0060] Use the built-in measurement tools in the software to conduct a detailed inspection of the groove and positioning block 2 after simulated wearing. The measurement tool first determines whether there is a misalignment setting between the groove and positioning block 2. If there is a misalignment, the software will further measure the specific parameters of the misalignment, mainly the misalignment distance. The measurement method is to select specific reference points on the groove and positioning block 2 (such as the center of the groove and the geometric center of positioning block 2) and calculate the actual distance between the two reference points in three-dimensional space. At the same time, the software will also analyze the direction of the misalignment to determine whether there is a misalignment in the horizontal direction, vertical direction or other angles, providing comprehensive data support for subsequent evaluation and adjustment.

[0061] Compare the measured misalignment distance with the preset reasonable range. The preset reasonable range is determined based on many factors such as the mechanical principles of orthodontic correction, clinical experience, and the manufacturing accuracy of braces and correction aids. For example, in the horizontal direction, a reasonable misalignment distance may be set within the range of ±0.2mm, and in the vertical direction it may be within the range of ±0.15mm. If the measured misalignment distance is within this reasonable range, the software will automatically confirm that the braces meet the requirements and generate a corresponding quality report. This report contains information such as the model data of the braces, the simulated wearing effect, the positional relationship between the groove and the positioning block 2, and the measurement results of the misalignment distance, providing a basis for subsequent production and use.

[0062] If the misalignment distance is not within a reasonable range, the software will automatically generate an adjustment plan based on the measurement results. The adjustment plan includes suggestions for modifying the braces model, such as adjusting the position, shape or depth of the groove, or changing the distribution angle of the positioning block 2 on the ring 1. The technician manually or automatically adjusts the braces model in the braces design software according to the adjustment plan provided by the software (if the software has an automatic optimization function). After the adjustment is completed, simulate wearing and misalignment detection are performed again until the misalignment distance meets the requirements. If the standard cannot be met after multiple adjustments, the software will determine that the braces need to be remade. At this time, a new braces 3D model will be regenerated, and the above simulated wearing, detection and adjustment process will be repeated to ensure that the braces finally produced can perfectly match the orthodontic auxiliary device and achieve accurate orthodontic correction effects. Throughout the process, the software will record each adjustment operation and result to form a detailed braces production process file for easy traceability and quality control.

[0063] Specifically, in some possible embodiments, the method further includes: Obtaining the current dental model and the current orthodontic appliance model of the patient at the current treatment stage; storing model data of a current tooth model and model data of a current orthodontic appliance model; Based on the current tooth model and the current orthodontic appliance model, determining the positional relationship between the groove and the positioning block 2 in the current orthodontic appliance model; Based on the current tooth model, the adjustment scheme of the groove and the positioning block 2 is automatically calculated to adapt to the changes of the teeth.

[0064] During each stage of the patient's orthodontic treatment, the patient's oral cavity is scanned regularly using an oral scanning device. The scanning device uses advanced non-contact optical scanning technology to quickly and accurately obtain the three-dimensional model data of the patient's current teeth and orthodontic devices in the oral cavity. During the scanning process, the patient needs to keep the oral cavity still, and the scanning device scans the oral cavity at multiple angles to ensure that the shape and position changes of the teeth and the status of the orthodontic device are fully captured. The acquired raw scan data is preprocessed and spliced ​​to form a complete current tooth model and current orthodontic device model.

[0065] After the data is acquired, the model data is transmitted to the central data management system in real time through wireless transmission technology (such as Wi-Fi or Bluetooth). The central data management system classifies and organizes the data, stores it according to the patient's personal information and treatment stage, and builds a complete patient orthodontic treatment file.

[0066] The central data management system imports the data of the current tooth model and the current orthodontic appliance model into professional analysis software. The software uses image recognition and feature extraction algorithms to identify the groove and positioning block 2 structure in the orthodontic appliance model, as well as the characteristic points related to it on the tooth model. By calculating the spatial coordinate relationship between these characteristic points, the actual position relationship between the groove and the positioning block 2 on the teeth in the current orthodontic appliance model is determined. For example, the relative distance between the center of the groove and the center of the positioning block 2, the angle deviation and other parameters are calculated, and the fit of the groove and the positioning block 2 in different parts of the tooth (such as the mesial, distal, buccal, lingual, etc. of the crown) is analyzed to generate a detailed position relationship report.

[0067] Based on the current tooth model, the analysis software further evaluates the changes in the teeth since the last stage of treatment. Using advanced machine learning algorithms and orthodontic mechanical models, the software automatically calculates the adjustment scheme required for the groove and positioning block 2 to adapt to the current changes in the teeth based on the change parameters such as the direction of movement, movement amount, rotation angle, etc. of the teeth, combined with the goals and expected effects of orthodontic treatment. During the calculation process, the software considers multiple factors, such as the remaining correction space, the force balance of the teeth, the health of the periodontal tissues, etc. For example, if the teeth move more in a certain direction, the software will calculate how the groove and positioning block 2 should adjust the angle or position to apply appropriate correction force to guide the teeth to continue to move to the ideal position while avoiding excessive pressure on the teeth and periodontal tissues. The adjustment scheme includes specific adjustment values ​​(such as the displacement of the groove, the rotation angle of the positioning block 2, etc.) and the order and timing of the adjustment, providing doctors with scientific and accurate treatment decision-making basis. Throughout the process, the software continuously learns and optimizes the calculation model, and improves the accuracy and effectiveness of the adjustment scheme based on a large amount of clinical data and actual treatment effect feedback.

Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
