[0041] Combine the following Figure 1-Figure 5 The present invention describes an orthodontic correction device and a monitoring method, system, electronic device and storage medium for the orthodontic correction device.

[0042] Figure 1 Schematic diagram of the orthodontic correction device provided by the present invention, such as Figure 1 As shown, the orthodontic correction device includes an invisible orthodontic correction device 11, a sensor 21 and a radio frequency signal transceiver 31;

[0043] The radio frequency signal transceiver 31 is wirelessly connected to the sensor 21 for sending an inquiry signal to the sensor 21;

[0044] The sensor 21 is placed at a point to be monitored on the surface of the invisible orthodontic appliance 11 and is stably connected to the invisible orthodontic appliance 11, wherein the point to be monitored is a stress point on the invisible orthodontic appliance 11 where stress concentration or change is the greatest;

[0045] The sensor 21 is used to collect the orthodontic correction force of the invisible orthodontic appliance 11 after receiving the inquiry signal, and send the data of the orthodontic correction force to the radio frequency signal transceiver 31 through the reflection signal;

[0046] The radio frequency signal transceiver 31 is also used to analyze the reflected signal after receiving the reflected signal to obtain the orthodontic correction force.

[0047] In an embodiment of the present invention, the orthodontic correction device is composed of an invisible orthodontic appliance 11, a sensor 21 and a radio frequency signal transceiver 31, the purpose of which is to solve the problem that the correction force cannot be monitored in real time in traditional orthodontic treatment, so as to optimize the correction effect. During the orthodontic treatment process, the correction force applied to the teeth must be appropriate so as to gradually move the teeth to the predetermined position. If the correction force is too small, the correction effect will be weakened; if the correction force is too large, it may cause damage to the teeth or periodontal tissues. Therefore, real-time monitoring of changes in correction force is crucial to improving the accuracy and safety of orthodontic treatment.

[0048] In this embodiment, the radio frequency signal transceiver 31 is connected to the sensor 21 via wireless communication, and is mainly used to send an inquiry signal to the sensor 21. The wireless communication method makes the device more comfortable when worn by the patient and avoids the inconvenience and limitations caused by wired connection.

[0049] The sensor 21 is installed at the monitored point on the surface of the invisible orthodontic appliance 11 and is stably connected to the invisible orthodontic appliance 11. The purpose of setting the sensor 21 is to monitor in real time the changes in the corrective force applied to the teeth during the orthodontic correction process, so as to ensure that the corrective force during the correction process is always within a reasonable range. The selection of the monitored point is based on a detailed analysis of the mechanical behavior of the invisible orthodontic appliance 11 during the movement of teeth. Due to the uneven distribution of the corrective force at different positions, certain areas of the invisible orthodontic appliance 11 usually bear greater forces and become areas of stress concentration or the most obvious changes. These areas are usually the key positions where the corrective force acts, so selecting these points as the monitored points can ensure that the sensor 21 can accurately reflect the changes in force during the orthodontic process.

[0050] When the sensor 21 receives the query signal, it immediately starts to collect the current correction force. The sensor 21 is located in the stress concentration area of ​​the invisible orthodontic appliance 11, so it can accurately sense the force applied to the teeth. Through the sensor 21, the physical change of the correction force is converted into an electrical signal.

[0051] The force signal acquired by the sensor 21 is converted into a radio frequency reflection signal through the antenna 203, and then the reflection signal is sent back to the radio frequency signal transceiver 31. After receiving these reflection signals, the radio frequency signal transceiver 31 can accurately calculate the correction force currently applied by the invisible orthodontic appliance 11 by analyzing its frequency and intensity. In this way, the entire system can complete the monitoring of the correction force in a wireless manner, realizing the function of obtaining real-time data without physical connection.

[0052] In a possible implementation, the sensor 21 includes a sensor housing and a sensor chip, wherein the sensor housing is connected to the sensor chip.

[0053] In the embodiment of the present invention, the sensor 21 is composed of a sensor housing and a sensor chip, and the sensor housing is closely connected to the sensor chip. The purpose of this design is to protect the sensitive components of the sensor chip during orthodontic treatment, so that it can work stably in the harsh environment in the oral cavity, and at the same time ensure that the chip can effectively collect correction force data.

[0054] The sensor chip is the core component of the sensor 21, which is responsible for sensing and collecting the correction force applied by the invisible orthodontic appliance 11. Therefore, the working environment of the chip is crucial. In the oral cavity, the sensor 21 needs to withstand multiple external influences such as frequent chewing movements, moisture and temperature changes. Therefore, the design of the sensor housing must not only have good sealing and biocompatibility, but also provide sufficient mechanical strength to protect the chip from external damage.

[0055] In specific implementation, the sensor housing is made of biocompatible materials, such as medical-grade ceramics, plastics or metal materials. These materials can be used for a long time in the oral environment without causing allergic or irritating reactions. The sensor housing is reliably connected to the sensor chip through precision machining to ensure that the chip can still work stably when subjected to external forces. The housing not only plays a physical protective role, but also prevents the chip from getting damp or being interfered with by external impurities, thereby ensuring the long-term stability and accuracy of the sensor 21.

[0056] In a possible implementation, the sensor 21 is fixed at the point to be monitored, or is printed at the point to be monitored by 3D printing technology.

[0057] In an embodiment of the present invention, the sensor 21 is fixed to the monitored point of the invisible orthodontic appliance 11, or is directly printed on the monitored point by 3D printing technology. The purpose of this design is to accurately monitor the correction force applied by the appliance to the teeth during the correction process to ensure the accuracy and real-time feedback of orthodontic treatment. The monitored points are usually located in the areas on the appliance where stress concentration or changes are most obvious. These areas are the key positions where forces act during tooth movement. Therefore, installing or printing sensors 21 at these positions can effectively capture changes in force and ensure smooth progress of correction.

[0058] In specific operations, the point to be monitored is determined based on the analysis of the patient's tooth arrangement and the mechanical behavior of the invisible orthodontic appliance 11. Through mechanical simulation or actual measurement, the area where the invisible orthodontic appliance 11 is subjected to the greatest force during tooth movement is found. The force change in this area is the most obvious, and it is the best position to monitor the correction force. The sensor 21 can be fixed to the point to be monitored in the following two ways:

[0059] Fixing method: Use medical-grade adhesive to fix the sensor 21 at the point to be monitored. The adhesive must have strong adhesion and biocompatibility to ensure that the sensor 21 is stable in the oral environment for a long time and does not produce adverse reactions to the human body. By fixing in this way, the sensor 21 can fit tightly on the surface of the invisible orthodontic appliance 11 and will not move or fall off due to external forces such as friction or chewing during wearing, thereby ensuring that the sensor 21 is always in the best monitoring position.

[0060] 3D printing method: Use 3D printing technology to print the sensor 21 directly on the point to be monitored. This method makes the sensor 21 more closely integrated with the invisible orthodontic appliance 11. The integrated design not only ensures the stability of the sensor 21, but also can accurately locate the position of the sensor 21 during the production process, reducing the complexity of later fixation. This printing method is particularly suitable for orthodontic correction with high precision requirements. By embedding the sensor 21 into the appliance structure, it is more durable and comfortable to wear.

[0061] Through these two methods, the sensor 21 can be stably installed at the point to be monitored, thereby ensuring that it can accurately monitor the force applied by the appliance. The stability of the sensor 21 is crucial to the accuracy of the data, because only when the sensor 21 is in a stable state can the subtle changes in the correction force be accurately captured. If the sensor 21 is displaced, it may cause inaccurate monitoring data, thereby affecting the correction effect.

[0062] In one possible implementation, refer to Figure 2 , Figure 2 It is a schematic diagram of the sensor chip provided by the present invention, the sensor chip includes a piezoelectric substrate 201, a metal interdigital electrode 202 and an antenna 203; the metal interdigital electrode 202 includes an interdigital transducer electrode 2021 and a reflection grating 2022; the interdigital transducer electrode 2021 and the reflection grating 2022 are placed on the surface of the piezoelectric substrate 201; the antenna 203 is connected to the interdigital transducer electrode 2021.

[0063] In an embodiment of the present invention, the design of the sensor chip includes a piezoelectric substrate 201, a metal interdigital electrode 202, and an antenna 203. The structural design of the chip is intended to achieve high-precision orthodontic correction force measurement and transmit data to a radio frequency signal transceiver 31 via wireless communication. By using the piezoelectric substrate 201 and the metal interdigital electrode 202, the sensor 21 can sensitively detect the tiny force changes applied by the invisible orthodontic appliance 11 on the teeth and convert these changes into measurable electrical signals.

[0064] The core component of the sensor chip is the piezoelectric substrate 201, which is usually made of materials such as quartz, lithium niobate, and lithium tantalate because of its excellent piezoelectric properties. Piezoelectric materials can generate electric charges when force is applied, thereby converting mechanical force into electrical signals. This property is very suitable for monitoring the force applied to teeth under the action of braces.

[0065] The metal interdigital electrodes 202 include an interdigital transducer electrode 2021 and a reflective grating 2022, both of which are placed on the surface of the piezoelectric substrate 201. The interdigital transducer electrode 2021 is responsible for converting the mechanical vibration generated by the piezoelectric substrate 201 into an electrical signal, while the reflective grating 2022 is responsible for reflecting the electromagnetic wave signal so as to be wirelessly transmitted through the antenna 203. The design of the metal interdigital electrodes 202 can enhance the sensor 21's ability to sense tiny force changes, ensuring that the sensor 21 can accurately capture the force applied by the invisible orthodontic appliance 11.

[0066] In specific operation, when the invisible orthodontic appliance 11 applies correction force to the teeth, the force will produce a small mechanical deformation through the piezoelectric substrate 201, thereby generating an electrical signal. This electrical signal is further amplified and processed by the interdigital transducer electrode 2021. The antenna 203 is connected to the interdigital transducer electrode 2021 and is responsible for wirelessly transmitting the processed signal to the radio frequency signal transceiver 31. This design ensures that the sensor chip can continuously monitor the change of force and feed back the data to the external device in real time.

[0067] In a possible implementation, the piezoelectric substrate 201 is quartz, lithium niobate, lithium tantalate, PVDF, zinc oxide, PZT, aluminum nitride, silicon dioxide, or a multilayer composite structure consisting of at least two of the above materials.

[0068] In an embodiment of the present invention, the piezoelectric substrate 201 in the sensor chip is made of materials such as quartz, lithium niobate, lithium tantalate, PVDF, zinc oxide, PZT, aluminum nitride, silicon dioxide, or a multilayer composite structure composed of at least two of these materials. The purpose of this design is to improve the sensitivity and accuracy of the sensor 21 to small force changes during orthodontic correction. The selection of these materials, especially the combined use of multilayer composite structures, can effectively optimize the piezoelectric effect and enhance the mechanical response characteristics of the sensor 21.

[0069] Piezoelectric materials can generate electric charges under the action of external forces, so they are very suitable for monitoring the correction force applied by orthodontic appliances. Materials such as quartz, lithium niobate, and lithium tantalate are often used in situations requiring high-precision mechanical sensing due to their stable piezoelectric properties and excellent mechanical properties. For example, quartz has good temperature stability and durability, allowing it to work for a long time in a complex oral environment; while lithium niobate and lithium tantalate, due to their high piezoelectric coefficients, can generate larger electrical signals under smaller forces, thereby enhancing the sensitivity of sensor 21.

[0070] Figure 3 FIG. 1 is a flow chart of a monitoring method for an orthodontic correction device provided by the present invention, such as Figure 3 As shown, including but not limited to the following steps:

[0071] Step 1: Simulate and analyze the force on the orthodontic appliance during tooth movement to obtain the force distribution of the orthodontic appliance during tooth movement.

[0072] In an embodiment of the present invention, the purpose of step 1 is to determine the mechanical properties and key stress areas of the orthodontic appliance by simulating and analyzing the stress conditions of the orthodontic appliance during tooth movement. This analysis is crucial for accurately monitoring the correction force during the orthodontic process, because different teeth are subjected to different forces during movement, and the distribution of these forces directly affects the effect of the correction. Through simulation analysis, the areas where the orthodontic appliance may be subjected to the maximum stress or stress changes during tooth movement can be identified in advance, providing a basis for subsequent monitoring.

[0073] In the specific operation, firstly, based on the three-dimensional model of the patient's teeth, combined with the expected path of tooth movement and the design parameters of the appliance, the mechanical simulation methods such as finite element analysis (FEA) are used to simulate the force conditions of the orthodontic appliance at different stages. This analysis process takes into account the angle of force applied by the appliance on the teeth, the resistance of the teeth, and the response of the periodontal tissue, so as to obtain the distribution of the correction force at different positions on the surface of the teeth and the appliance. The simulation analysis can accurately calculate the force value in each area and show the areas where the force is concentrated or changes greatly.

[0074] The results of this mechanical simulation not only provide a basis for determining the points to be monitored, but also help orthodontists foresee possible orthodontic problems, such as insufficient orthodontic force or excessive periodontal pressure caused by local excessive force. Based on the simulation, orthodontists can fine-tune the design of the orthodontic appliance to ensure that the orthodontic appliance can apply the appropriate force as expected during actual wearing.

[0075] Step 2: Based on the force distribution, determine the points to be monitored on the orthodontic appliance.

[0076] In the embodiment of the present invention, the purpose of step 2 is to determine the points to be monitored on the orthodontic appliance based on the force distribution in step 1. This step is crucial because the points to be monitored represent the locations where stress concentration or changes are most obvious during tooth movement. Selecting appropriate monitoring points can ensure that the sensor can capture the most critical changes in correction force and provide real-time feedback to the correction staff.

[0077] In a possible implementation, step 2 specifically includes the following steps:

[0078] In the stress distribution, determine the stress point where the stress is concentrated or changes the most, and use the stress point as the point to be monitored.

[0079] In the specific operation, firstly, according to the force distribution simulation results in step 1, the stress conditions of the appliance at various positions are systematically analyzed. The selection of force points is mainly concentrated in the stress concentration area, that is, the maximum correction force point generated when the appliance contacts the teeth. These positions are usually the areas that are most sensitive to force during tooth movement. By monitoring these areas, the most representative mechanical data can be obtained.

[0080] To determine the stress concentration or the point of greatest change, simulation techniques such as finite element analysis (FEA) are used to calculate the change in the correction force applied by the appliance at different times and locations. Through analysis, stress concentration points or areas with the greatest force change can be found. These areas are usually located in the direction of tooth movement or on the force-bearing side of a specific tooth, such as the tip of the incisor or the force-bearing area at the root of the molar.

[0081] When finally determining the stress points as monitoring points, select those areas where significant stress changes will occur during the correction process. This stress change may be caused by the adjustment of the direction of tooth movement or the mechanical properties of the appliance. The areas of stress concentration can fully reflect the key mechanical state during correction, so using these areas as monitoring points can ensure the effectiveness and real-time nature of the monitoring data.

[0082] Step 3: Obtain the baseline orthodontic correction force and actual orthodontic correction force of the point to be monitored.

[0083] In an embodiment of the present invention, the purpose of step 3 is to obtain the baseline orthodontic correction force and the actual orthodontic correction force of the monitored point, so as to ensure that the correction personnel can grasp in real time whether the force applied during the correction process meets expectations. This step is very critical because the effect of orthodontic correction is highly dependent on whether the applied correction force is within a reasonable range. Excessive force can cause damage to teeth and periodontal tissues, while too little force may cause the correction to be prolonged or ineffective. Therefore, real-time monitoring and comparison of the baseline orthodontic correction force and the actual orthodontic correction force is an important link to ensure the accuracy of correction.

[0084] In specific implementation, the benchmark orthodontic correction force is first determined. The benchmark orthodontic correction force refers to the ideal applied force designed according to the correction plan. This force value is obtained through analysis of tooth arrangement, correction goals and tooth movement direction. Before the start of correction, the ideal force value that the monitored point should bear at different stages is determined through finite element analysis, mechanical simulation or other related calculation methods. This force value is usually a standard value set by the orthodontic staff according to the specific situation of the patient, which is used as a comparative reference.

[0085] Next, obtain the actual orthodontic correction force. The actual orthodontic correction force is the force value monitored in real time by the sensor. This data is collected from the sensor at the point to be monitored and sent to the radio frequency signal transceiver through wireless transmission. When the patient wears the orthodontic appliance, the sensor continuously records the mechanical state of the point to be monitored, reflecting the actual force value applied by the appliance during the correction process. These force values ​​may change as the teeth move, so it is very important to continuously monitor and record this data.

[0086] Step 4: When the actual orthodontic correction force does not change for a preset number of consecutive times, or when the actual orthodontic correction force is less than the reference orthodontic correction force, it is determined that the orthodontic correction device needs to be replaced.

[0087] In an embodiment of the present invention, the purpose of step 4 is to determine whether the orthodontic device needs to be replaced by real-time monitoring of changes in orthodontic correction force. Specifically, when the actual orthodontic correction force does not change for a preset number of consecutive times, or when the actual orthodontic correction force is less than the reference orthodontic correction force, it is determined that the current orthodontic correction device can no longer effectively apply the correction force, and it should be replaced with the next stage of the correction device. The purpose of this step is to ensure that orthodontic correction can proceed smoothly as planned, and to adjust the correction in time when the teeth reach a certain stage of movement to avoid ineffective correction force application.

[0088] In specific operations, the sensors of the orthodontic appliance will continuously monitor the actual correction force at the monitored point. The system sets a preset threshold for continuous monitoring times to determine whether the force value has changed. If the actual correction force measured for multiple consecutive times (for example, three times) is the same as the previously measured force value, this usually indicates that the tooth has reached the limit of movement under the action of the current appliance, and the force of the appliance has stabilized and no longer applies sufficient movement force to the tooth. At this time, the appliance has completed the current stage of work and needs to be replaced with a new appliance to continue correction.

[0089] In addition, if the actual orthodontic correction force monitored is less than the previously set baseline orthodontic correction force, it means that the appliance has lost sufficient force-applying capacity. At this point, even if you continue to wear the current appliance, the teeth will not move significantly. This may be because the teeth have adapted to the force of the appliance, or the appliance has lost its original force-applying capacity over time. Therefore, this is also one of the criteria for judging the need to replace the appliance.
