[0002] In the history of orthodontics, an orthodontic appliance was developed to replace the traditional correction technology. The orthodontic appliance is a flexible and movable orthodontic appliance that can be freely removed and worn by the monitored person. By constantly replacing the orthodontic appliance, a good tooth cusp-fossa interlacing relationship can be established.

[0003] However, the success of orthodontic treatment is highly dependent on whether the orthodontic device applies accurate force to the teeth during the entire treatment process. Traditional orthodontic treatment methods usually rely on the doctor's experience and regular feedback from the monitored personnel, and judge the use of orthodontic devices through visual inspection and feedback from users. However, this judgment process is highly dependent on the professional level of the orthodontist, so it is impossible to accurately obtain the effect of the orthodontic treatment process, which leads to unsatisfactory treatment results and ultimately affects the effect of orthodontic treatment.

[0049] Combine the following Figure 1-Figure 8 The present invention describes a monitoring method, system, electronic device and storage medium for an orthodontic correction process.

[0050] Figure 1 This is one of the flow charts of the monitoring method of the orthodontic correction process provided by the present invention, such as Figure 1 As shown, including but not limited to the following steps:

[0051] Step 1: Obtain the dental arrangement of the person to be monitored.

[0052] In order to ensure that the invisible orthodontic appliance can effectively apply the correction force and achieve precise movement of teeth, it is first necessary to obtain the tooth arrangement of the person to be monitored. This step is crucial because the tooth arrangement of each person to be monitored is unique and directly determines the design and effect of orthodontic treatment. By obtaining the tooth arrangement of the person to be monitored, accurate basic data can be provided for the subsequent design of the orthodontic appliance, thereby ensuring that the orthodontic appliance can fit closely to the teeth of the person to be monitored and achieve effective correction force application.

[0053] Specifically, this process first requires a 3D scan of the teeth of the person to be monitored, using advanced 3D scanning technology, such as an oral scanner, to obtain an accurate 3D model of the teeth and their arrangement. These data can fully reflect the current tooth arrangement of the person to be monitored, including the shape, position and distance between the teeth. Then, using these 3D data, a virtual model of the dentition of the person to be monitored is constructed in computer-aided design (CAD) software.

[0054] Step 2: Determine the orthodontic appliance that matches the tooth arrangement, and simulate and analyze the force on the orthodontic appliance during tooth movement to obtain the force distribution of the orthodontic appliance during tooth movement.

[0055] The design and monitoring of orthodontic appliances are key to ensuring accurate application of correction force during tooth movement. To achieve this goal, it is necessary to conduct a detailed simulation analysis of the force applied to the orthodontic appliance during tooth movement, so as to determine the force distribution of the orthodontic appliance in actual use.

[0056] Specifically, first, it is necessary to design the orthodontic appliance in detail through computer-aided design (CAD) software based on the acquired tooth arrangement of the person to be monitored. At this time, the orthodontic appliance is made by hot pressing or 3D printing technology to ensure that its shape completely matches the tooth arrangement of the person to be monitored. This design ensures that the orthodontic appliance can fit the teeth of the person to be monitored tightly and effectively apply the expected correction force.

[0057] Next, mechanical simulation tools such as finite element analysis (FEA) are used to simulate and analyze the forces applied by the orthodontic appliance during tooth movement. This analysis can accurately calculate the stress and strain distribution applied by the orthodontic appliance at each tooth position. By simulating the movement of teeth under the action of the correction force, the force distribution diagram is determined, and the stress concentration area or the position with the greatest change of the orthodontic appliance at different stages is found.

[0058] Step 3: Based on the force distribution, determine the points to be monitored on the orthodontic appliance.

[0059] In a possible implementation, step 3 specifically includes the following steps:

[0060] 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.

[0061] Specifically, based on the previous force distribution simulation analysis, the stress points where the stress concentration or change is the largest during the tooth movement of the orthodontic appliance have been determined. The stress points are the locations in the monitoring area where significant deformation is most likely to occur, and are also the key monitoring points for the effect of the correction force. By determining the points to be monitored in these monitoring areas and using strain sensors to monitor the deformation and stress conditions of the points to be monitored in real time, specifically, by mounting strain sensors in the monitoring areas and collecting and storing data on the deformation of the invisible orthodontic appliance during wearing, the deformation and stress conditions of the orthodontic appliance in actual use can be effectively monitored.

[0062] Step 4: Based on the monitoring data of the monitored points when the monitored person uses the orthodontic appliance, the usage status of the orthodontic appliance is obtained.

[0063] Specifically, it is crucial to analyze the use of orthodontic appliances through monitoring data. The changes in the force applied to the orthodontic appliance during tooth movement can reflect the use effect of the orthodontic appliance and its adaptability in actual operation. Therefore, based on the monitoring data obtained when the monitored person uses the orthodontic appliance, the use of the orthodontic appliance can be accurately judged.

[0064] In the present application, monitoring data can be divided into two types of data: actual dot patterns and actual force values. Therefore, the present application can obtain the usage of the orthodontic device based on the actual dot patterns of the monitored points when the monitored person uses the orthodontic device, or obtain the usage of the orthodontic device based on the actual force values ​​of the monitored points when the monitored person uses the orthodontic device. The usage refers to whether the orthodontic treatment effect of the monitored person meets expectations, and whether the orthodontic device needs to be adjusted or replaced.

[0065] In the following embodiments, the above two methods will be described in detail.

[0066] In one possible implementation, the monitoring data includes an actual dot pattern. Figure 2 , Figure 2 This is a second flow chart of the method for monitoring the orthodontic correction process provided by the present invention. In the first embodiment, step 4 specifically includes steps 41-42:

[0067] Step 41: Obtaining an original dot pattern of the point to be monitored, where the original dot pattern is a dot pattern with the point to be monitored as a reference point.

[0068] In step 41, obtaining the original dot pattern of the point to be monitored is a key step to ensure subsequent monitoring and analysis. The original dot pattern, as a reference pattern, provides a standard state of the orthodontic device without external interference or force. The original dot pattern can be circular, rectangular, or polygonal. The original dot pattern of this application takes a circular dot pattern as an example, which can be referred to Figure 3 , Figure 3 It is a schematic diagram of the original dot matrix provided by the present invention. Step 41, by clarifying the reference state, can subsequently accurately determine whether the orthodontic correction device has been deformed during actual use and the degree of deformation, thereby evaluating the correction effect.

[0069] Specifically, after determining the position of the point to be monitored, an original dot pattern is generated with the point as the reference point (taking the circular dot pattern as an example, the point to be monitored is the center of the circle). The generation of this pattern is based on the measurement and recording of the initial state of the orthodontic device, which represents the stress distribution expected during the design and manufacturing stages of the orthodontic device. Therefore, the construction of the original dot pattern needs to take into account the material properties, geometric shape and initial stress conditions of the orthodontic device.

[0070] Step 42: Taking the point to be monitored as a reference point, the actual dot pattern and the original dot pattern are analyzed to obtain the usage of the orthodontic correction device.

[0071] In step 42, by analyzing the actual dot pattern and the original dot pattern, the state change of the orthodontic appliance during use can be accurately determined. The core of this step is to use the point to be monitored as a reference point, comprehensively analyze the difference between the actual dot pattern and the original dot pattern, so as to evaluate the use effect of the orthodontic appliance and potential adjustment needs.

[0072] The reason for this analysis is that orthodontic appliances may be deformed during actual use due to various factors (such as oral environment, changes in bite force, etc.). If this deformation is not discovered and handled in time, it may affect the treatment effect and even have an adverse effect on the oral health of the monitored personnel. Therefore, by comparing the actual dot matrix pattern with the original dot matrix pattern, the deformation of the orthodontic appliance can be discovered in time to ensure the effectiveness and safety of the treatment process.

[0073] In one possible implementation, refer to Figure 4 , Figure 4 This is the third flow chart of the monitoring method of the orthodontic correction process provided by the present invention, and step 42 specifically includes steps 421-424:

[0074] Step 421: Taking the point to be monitored as a reference point, respectively determine the deformation amount of the actual dot pattern compared with the original dot pattern at each preset angle.

[0075] In step 421, by analyzing the deformation amount of the actual dot pattern compared to the original dot pattern at each preset angle, it is possible to accurately determine whether the orthodontic device has been deformed during use. The reason for this analysis is that the orthodontic device may be affected by uneven forces or other external factors during use, causing its shape to change. This change is often not overall, but local, so by analyzing the deformation amount at each preset angle, the specific location and degree of these local changes can be identified, thereby evaluating the impact of the deformation.

[0076] Specifically, first, the center of the actual dot pattern needs to be aligned with the center of the original dot pattern to ensure that the reference points of the two are consistent. Then, multiple preset angles (such as 0 degrees, 45 degrees, 90 degrees...315 degrees) are selected around the point to be monitored. These angles are determined based on the structural characteristics of the orthodontic correction device and the common force direction. At each preset angle, the radial difference between the actual dot pattern and the original dot pattern is measured. This difference is the deformation amount, which can be recorded as B0, B45, B90...B315.

[0077] In this way, the slight deformation of the orthodontic device in various directions can be accurately captured. If the deformation at all preset angles is zero, it means that the orthodontic device has not deformed during use, and the correction effect is as expected. However, if non-zero deformation appears at certain angles, it means that the orthodontic device has deformed in these directions. The size and direction of the deformation can reflect the specific situation of the orthodontic device being subjected to force, and then infer the possible stress concentration area or cause of deformation.

[0078] Step 422: When all deformation amounts are zero, determine the usage of the orthodontic correction device.

[0079] The reason for this analysis is that the effectiveness of orthodontic appliances depends on their precise shape and stress distribution. Orthodontic treatment is usually divided into multiple stages, each with a specific goal. The orthodontic appliance of one stage is designed to push the teeth to a specific position. When the orthodontic appliance applies the correction force, it will guide the teeth to gradually move to the target position. However, as the teeth move, the force applied by the orthodontic appliance on the teeth will gradually decrease. When the force value tends to stabilize or no longer changes, it means that the force applied by the orthodontic appliance is no longer sufficient to continue to push the teeth to move, and the effectiveness of the correction force has declined.

[0080] If the orthodontic appliance maintains the same shape as the original design during use, that is, the deformation at each preset angle is zero, it means that the teeth and alveolar bone have sufficiently adapted to the current force. At this time, the orthodontic appliance needs to be replaced to enter the next treatment stage to apply new force to continue to guide tooth movement.

[0081] Step 423: When any deformation variable is not zero, based on each deformation variable, the stress value of the actual dot pattern at each preset angle is calculated.

[0082] In step 423, by calculating the stress values ​​of the actual dot pattern at each preset angle, the deformation that may occur in the orthodontic device during use can be deeply analyzed. The key to this step is to convert the deformation variable into a stress value through further processing, so as to quantify the force borne by the orthodontic device in different directions, and then evaluate the stress state of the orthodontic device during use and its impact on the correction effect. The deformation variable itself can only reflect the change in the shape of the orthodontic device, but cannot directly reveal the mechanical reasons behind this change. By calculating the stress value, the root cause of the deformation can be understood more accurately, and it can be determined whether the orthodontic device is in a state of uneven force. If the orthodontic device is subjected to excessive stress in certain directions, it may cause excessive deformation and affect the correction effect.

[0083] In a possible implementation, step 423 specifically includes the following steps:

[0084] The stress value is calculated by the following formula:

[0085] ;

[0086] in, is the stress value at the i-th preset angle, K is the elastic modulus of the material used in the orthodontic correction device, is the deformation at the i-th preset angle.

[0087] Specifically, first take the point to be monitored as the reference point, and use the formula according to the deformation obtained in the previous step Calculate the stress value at each preset angle, where is the stress value at the i-th preset angle, K is the elastic modulus of the material used in the orthodontic correction device, is the deformation at the i-th preset angle. This formula is based on the basic principle of material mechanics, that is, stress is proportional to deformation, and the elastic modulus K reflects the deformation response characteristics of the material under stress.

[0088] Step 424: When all stress values ​​for a preset number of consecutive times do not change, the usage of the orthodontic correction device is determined.

[0089] In step 424, by monitoring the change in stress value within a preset number of consecutive times, the effectiveness of the orthodontic appliance in the current treatment stage can be determined, and it can be determined whether the orthodontic appliance needs to be replaced to enter the next treatment stage. Since orthodontic correction is usually divided into multiple stages, the goal of each stage is to gradually move the teeth to a predetermined position through the force applied by the orthodontic appliance. Therefore, as the teeth move, the force applied by the orthodontic appliance on the teeth will gradually decrease. When the stress value tends to be stable or no longer changes, it indicates that the effectiveness of the correction force has decayed.

[0090] Specifically, in each monitoring, the stress values ​​of the monitored points at various preset angles are recorded. If these stress values ​​remain unchanged in several consecutive monitorings, it means that the teeth and alveolar bones have adapted to the current correction force and no longer move significantly. Therefore, it is necessary to replace the orthodontic appliance to enter the next treatment stage to apply new forces to continue to guide tooth movement.

[0091] In another possible implementation, the monitoring data also includes the actual force value. Figure 5 , Figure 5 This is the fourth flow chart of the monitoring method of the orthodontic correction process provided by the present invention, and step 4 specifically includes steps 43-44:

[0092] Step 43: Obtain the force reference value of the point to be monitored.

[0093] In step 43, obtaining the force reference value of the point to be monitored is a key step. The purpose of this step is to provide a clear reference point in the subsequent monitoring process to evaluate the mechanical state and effectiveness of the orthodontic appliance during use. The force reference value represents the ideal force condition applied by the orthodontic appliance on the teeth in the initial state, so obtaining this reference value is the basis for ensuring the accuracy of subsequent analysis and judgment.

[0094] The reason for this step is that the effectiveness of orthodontic treatment depends on the appropriate force applied by the orthodontic appliance to the teeth. As the teeth move, this force changes, so obtaining a force baseline value in the initial stage helps to determine the attenuation of the force during treatment. When the actual force value monitored is compared with the baseline value, it can be intuitively determined whether the mechanical state of the orthodontic appliance meets expectations, thereby determining whether the orthodontic appliance needs to be adjusted or replaced.

[0095] Specifically, the process of obtaining the force reference value includes the following steps: First, after the orthodontic device is installed for the first time, the initial force value at each preset angle is measured by monitoring the predetermined monitoring points in the orthodontic device. This initial force value is measured before the teeth begin to move, so it can represent the ideal force condition applied by the orthodontic device to the teeth under the design conditions. The specific measurement method can use a high-precision mechanical sensor to ensure the accuracy and reliability of the force reference value.

[0096] Once the force baseline is determined, it will serve as a reference point for subsequent monitoring. During treatment, any force changes that deviate from the baseline will be recorded and analyzed. In this way, the working status of the orthodontic appliance at different time points can be evaluated in real time to determine whether sufficient force can still be applied to promote tooth movement.

[0097] It should be noted that when the orthodontic device monitors the actual force value in real time, the monitoring sensor can be placed at the point to be monitored. The monitoring sensor can be placed on the surface of the orthodontic device by using 3D printing technology and other methods, and stably connected to the orthodontic device. The specific setting of the monitoring sensor can refer to Figure 6 , Figure 6 It is a schematic diagram of the monitoring strain sensing device provided by the present invention. The monitoring sensor can be a separate sensor including a housing and a sensor chip. The housing is made of ceramic, plastic, or metal. The housing is connected to the sensor chip to perform packaging and protection. The sensor chip includes a substrate, a coil, and interconnecting contacts, and can sense strain changes through resistance, capacitance, inductance, magnetoresistance, photoelectric effect, or sound; further, the sensor chip includes a strain sensor and a data collector; the data collector is used to collect, store, and process deformation data collected by the strain sensor. The data collector is connected to the strain sensor through an interconnection interface; the interconnection interface in the data collector can be realized by an independent physical contact probe, or the strain sensor and the data collector can be assembled through a flexible substrate to achieve interconnection.

[0098] Step 44: When the actual force value does not change for a preset number of consecutive times, or when the actual force value is less than the force reference value, the usage of the orthodontic correction device is determined.

[0099] In step 44, by comparing the actual force value of the monitored point with the reference force value, the use status of the orthodontic appliance can be accurately determined, and it can be determined whether the orthodontic appliance needs to be adjusted or replaced. The core of this step is to evaluate whether the orthodontic appliance can still effectively apply sufficient force to push the teeth to continue to move during use, so as to ensure the continuity and effectiveness of orthodontic treatment.

[0100] The reason for this step is that as the treatment progresses, the force applied by the orthodontic appliance on the teeth will gradually decrease. When the teeth gradually approach the designed target position, the force applied by the orthodontic appliance may tend to stabilize or even stop changing, which usually means that the teeth and alveolar bone have adapted to the current force and the effectiveness of the orthodontic appliance has weakened. Therefore, by monitoring the actual force value, it is possible to promptly determine whether the current orthodontic appliance can continue to effectively promote tooth movement, or whether the orthodontic appliance needs to be replaced to apply new force.

[0101] Specifically, first, the actual force value of the monitored point needs to be monitored regularly and compared with the previously obtained force reference value. If the actual force value remains consistent with the reference value or tends to be stable and no longer changes significantly for a consecutive preset number of times, this indicates that the orthodontic device has lost the ability to push the teeth to continue moving, and the teeth have adapted to the current correction force. At this point, the effectiveness of the orthodontic device has diminished, and a new orthodontic device may need to be replaced to provide new force to continue to push the teeth to move.

[0102] In addition, if the actual force value is less than the force reference value, it also indicates that the mechanical effect of the orthodontic appliance has weakened and can no longer effectively apply sufficient force. At this time, it is also necessary to consider replacing the orthodontic appliance to ensure that the treatment process is not interrupted.
