Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, and more particularly to a bite plate system and a method for detecting and intervening in abnormal oral behaviors. BACKGROUND

[0002] Temporomandibular disorders (TMD) is a common oral disease with a high incidence of 30-80%, which can cause temporomandibular joint pain, facial deformity, and mandibular movement disorders, etc. Its occurrence and development are closely related to the mental state, and seriously affect the quality of life of patients. Epidemiological studies show that about 40-60% of TMD patients also have bruxism (daytime clenching or nighttime grinding), and about 15-30% have abnormal tongue habits. These abnormal oral behaviors are particularly prominent in orthodontic patients and stress-sensitive groups, and can seriously affect the treatment effect and even cause irreversible changes in occlusion.

[0003] Bite plates are the main non-surgical intervention devices, but the existing bite plate technology has significant limitations: traditional bite plates can mechanically adjust the jaw position, but cannot monitor and correct the patient's clenching, grinding at night, and abnormal tongue movement, etc. pathogenic abnormal oral behaviors in real time, resulting in limited treatment effect; the patient may continue to clench and grind teeth at high intensity during wearing, and the related muscles are not effectively re-educated, and the symptoms are likely to recur once the wearing is stopped.

[0004] Existing intelligent improvements mainly focus on single-mode monitoring. For example, only integrating pressure sensors can only detect the clenching contact event and the force, but cannot distinguish between normal swallowing, occasional clenching, or continuous grinding symptoms, and more importantly, cannot perceive the position and activity of the tongue; only having an electromyography detection device can monitor the abnormal electrical activity of the masticatory muscles, but the signal is easily disturbed, the wearing comfort is poor, and the position and activity of the tongue cannot be perceived. Most importantly, most existing devices stop at monitoring and fail to achieve effective intervention. This diagnosis without treatment mode forms an open-loop system and cannot form a real-time feedback treatment closed loop. SUMMARY

[0005] The purpose of the present application is to overcome the shortcomings of the prior art and provide a bite plate system and a method for detecting and intervening in abnormal oral behaviors, which can accurately identify abnormal oral behaviors and provide real-time feedback to warn patients, achieving intelligent treatment and precise treatment.

[0006] To solve the above technical problems, the technical solution adopted by the present application is: a bite plate system, comprising: a bite plate main body; a sensor module comprising a first pressure sensor array and a second pressure sensor array mounted on the bite plate body, the first pressure sensor array for monitoring bite force, the second pressure sensor array for monitoring tongue pressure; a haptic feedback module mounted on the bite plate body for providing haptic cues to the user; a control module mounted on the bite plate body for signal transmission and processing, the first pressure sensor array and the second pressure sensor array being communicatively connected to an input of the control module, the haptic feedback module being communicatively connected to an output of the control module.

[0007] By integrating bite force and tongue pressure dual monitoring, comprehensive monitoring and real-time intervention are achieved. The system can comprehensively capture the two main abnormal oral behaviors (bruxism / teeth clenching and abnormal tongue) that cause TMD aggravation. Combined with haptic feedback, real-time closed-loop treatment from "perception" to "intervention" is realized, breaking the limitations of traditional bite plates that only have physical isolation without behavior correction function. By integrating the sensing, feedback and control modules on the bite plate body, high integration and miniaturization of the system are achieved, forming an independent and wearable integrated device, greatly improving the comfort and convenience of daily use for patients, and laying the foundation for long-term, unobtrusive home monitoring and treatment. By setting the control module, the foundation for intelligent treatment is laid, allowing simple sensor signals to be processed, analyzed and made into intelligent decisions, providing core hardware support for subsequent algorithm optimization, personalized threshold setting and other advanced functions.

[0008] The control module includes a control unit, a wireless communication unit for communication with a terminal device and / or a cloud server, and a power supply unit for powering the sensor module, the haptic feedback module, the control unit and the wireless communication unit; the sensor module, the haptic feedback module and the wireless communication unit are communicatively connected to the control unit; the terminal device is used to display real-time visual charts about the data collected by the sensor module, and to receive user input for configuring and updating the judgment threshold and feedback parameters of the control module; the cloud server is used to store trend reports reflecting changes in the frequency and intensity of the user's bite force exceeding the standard. Through wireless communication, doctors can remotely view data and adjust treatment parameters (such as threshold), and patients do not need to visit the doctor frequently, improving treatment efficiency and accessibility. Doctors can remotely and individually adjust the judgment threshold and feedback parameters based on the real-time data and long-term trends of each patient, to achieve a "tailored" dynamic treatment plan, avoiding one-size-fits-all and improving efficacy. The introduction of the cloud server enables the system to store and analyze long-term data and generate trend reports, thereby quantifying rehabilitation progress and providing objective, data-based evidence for doctors to assess treatment effectiveness, predict disease progression and adjust long-term treatment strategies.

[0009] The first pressure sensor array is embedded in the occlusal surface of the molar area of the bite plate body, and the second pressure sensor array is embedded in the lingual side of the lower anterior teeth of the bite plate body. The occlusal force monitoring point is arranged in the molar area (the main force bearing area of the occlusal force), and the lingual pressure monitoring point is arranged on the lingual side of the lower anterior teeth (the typical action point of the abnormal tongue protrusion behavior), so that the signals collected can best reflect the target abnormal behavior, and the accuracy and effectiveness of monitoring are improved; the layout scheme enables the sensors to be located in the functional area, and meanwhile, interference to the normal occlusion of teeth and the normal activity of the tongue is avoided, and the wearing comfort is maximized under the premise of ensuring the function.

[0010] The tactile feedback module comprises at least one resonance motor, which is installed on the buccal side of the molar area of the bite plate body and / or the lingual side area of the bite plate body. The resonance motor has the characteristics of fast starting, soft vibration and low energy consumption, and can provide a private feedback that only the wearer himself can clearly perceive and is not noticeable, which is very suitable for use in social occasions or sleep. The feedback device is arranged on the buccal side of the molar area and the lingual side area, so that the user can more intuitively and quickly understand the type of abnormal behavior indicated by the feedback through the difference in vibration position (for example, buccal side vibration prompts occlusal abnormality, and lingual side vibration prompts tongue protrusion abnormality), and the learning process of behavior correction is accelerated.

[0011] The lingual side of the lower anterior teeth of the bite plate body and the buccal side of the molar area of the two sides of the bite plate body are respectively provided with mounting cavities, and the resonance motor is installed in the mounting cavities. By opening the customized mounting cavities, the resonance motor can be perfectly embedded in the interior of the bite plate body, avoiding the formation of a conspicuous protrusion in the oral cavity, minimizing the foreign body sensation, protecting the oral soft tissue and improving the feasibility of long-term wearing. The mounting cavities provide a stable fixing base for the resonance motor, which helps the vibration energy to be more efficiently transmitted to the bite plate body and the oral tissue, ensuring that the feedback signal is clear and discernible.

[0012] The bite plate body is covered with a resin covering layer, and a stainless steel sheet is arranged between the resonance motor and the resin covering layer. The resin covering layer completely isolates the electronic elements from the oral environment, ensuring the biological safety and sealing of the system and preventing saliva erosion. At the same time, it also plays a role in smoothing the surface and improving comfort. The addition of the stainless steel sheet as a vibration diffusion plate can effectively convert the local strong vibration of the resonance motor into a larger area, more gentle but more perceptible vibration field, solving the problem of weak vibration perception caused by the small size of the micro motor, and greatly optimizing the user experience.

[0013] The application also provides a method for detecting and intervening in oral abnormal behavior, which adopts the above-mentioned bite plate system and comprises the following steps: S1, collecting the pressure signals in the oral cavity of the user in real time through the sensor module; S2, the control module processes and extracts features from the collected pressure signals to obtain characteristic values including bite force and tongue pressure; S3, compare the characteristic values with the preset threshold values, when the characteristic values exceed the corresponding preset threshold values, control the haptic feedback module to provide real-time haptic intervention to the user.

[0014] Preferably, the haptic feedback module includes a resonance motor arranged on the lingual side of the lower anterior teeth of the bite plate body and the buccal side of the molar area on both sides of the bite plate body; in step S3, the process of the haptic feedback module providing real-time haptic intervention to the user is: When the bite force characteristic value exceeds the preset bite force threshold value, it is determined that the vertical bite force is abnormal, and the resonance motors located on the buccal side of the molar area on both sides of the bite plate body are controlled to vibrate simultaneously; When the tongue pressure characteristic value exceeds the preset tongue pressure threshold value, it is determined that the tongue pressure is abnormal, and the resonance motor located on the lingual side of the lower anterior teeth of the bite plate body is controlled to vibrate.

[0015] By designing different vibration positions (both sides simultaneously vs. lingual side single point) for "occlusion abnormality" and "tongue pressure abnormality", the user can intuitively distinguish the current error behavior type without thinking, greatly improving the efficiency and accuracy of behavior retraining. Bilateral simultaneous vibration prompts occlusion abnormality, which is consistent with the physiological characteristics of bilateral coordination of occlusion behavior itself; while targeted lingual vibration directly points to the occurrence site of abnormal behavior, which is consistent with intuitive cognition and helps the brain quickly establish the cause-and-effect relationship between "behavior-feedback".

[0016] Preferably, in step S3, in addition to determining that the vertical bite force is abnormal, the time for which the bite force characteristic value exceeds the preset bite force threshold value must also exceed the preset first time threshold value; In addition to determining that the tongue pressure is abnormal, the time for which the tongue pressure characteristic value exceeds the preset tongue pressure threshold value must also exceed the preset second time threshold value.

[0017] It can effectively filter out transient signals generated by normal physiological activities such as swallowing, coughing, speaking or accidental tooth collision, ensuring that the system only intervenes when it detects a continuous, pathologically significant abnormal behavior, thereby improving the reliability and professionalism of the system and avoiding user frustration or abandonment of treatment due to frequent false positives.

[0018] Preferably, the control module includes a wireless communication unit in communication with a terminal device and / or a cloud server, which uses the terminal device to display a visual chart of the data collected by the sensor module in real time, and receives user input to configure and update the judgment threshold and feedback parameters of the control module, and / or uses the cloud server to store a trend report reflecting the frequency and intensity changes of the user's bite force exceeding the standard, to quantify the progress of rehabilitation.

[0019] By deeply integrating the treatment method with digital management, it is not only a separate treatment device, but also a digital medical platform connecting doctors and patients. The overall business model of "device + service" is realized, and the comprehensive effects of remote monitoring, personalized adjustment and quantitative evaluation are ensured.

[0020] Compared with the prior art, the present application has the following beneficial effects: (1) By integrating bite force and tongue pressure double monitoring, comprehensive monitoring and real-time intervention are realized. The system can comprehensively capture two main abnormal oral behaviors (bruxism / tight bite and abnormal tongue) that cause TMD to worsen. Combined with tactile feedback, real-time closed-loop treatment from "perception" to "intervention" is realized, breaking through the limitation of traditional bite plate which only has physical isolation but no behavior correction function. The sensing, feedback and control modules are all integrated on the bite plate main body, realizing high integration and miniaturization of the system, forming an independent and wearable integrated device, greatly improving the comfort and convenience of daily use of patients, and laying a foundation for long-term, unobtrusive home monitoring and treatment. By setting the control module, the foundation for intelligent treatment is laid, so that simple sensor signals can be processed, analyzed and made into intelligent decisions, providing core hardware support for subsequent algorithm optimization, personalized threshold setting and other advanced functions; (2) Through wireless communication, doctors can remotely view data and adjust treatment parameters (such as threshold), and patients do not need to frequently return to the hospital, improving treatment efficiency and accessibility. Doctors can remotely and individually adjust the judgment threshold and feedback parameters according to the real-time data and long-term trend of each patient, realize the "tailor-made" dynamic treatment scheme, avoid one-size-fits-all, and improve the curative effect. The introduction of cloud server enables the system to store and analyze long-term data, generate trend reports, and thus quantify the rehabilitation progress, providing objective and data-based basis for doctors to evaluate treatment effect, predict disease development and adjust long-term treatment strategy; (3) The resonant motor has the characteristics of fast start, soft vibration and low energy consumption, can provide a private feedback that only the wearer himself can clearly perceive, and is not noticeable, which is very suitable for use in social occasions or sleep. By setting the feedback device on the buccal side and the lingual side of the bruxism area, the user can more intuitively and quickly understand the type of abnormal behavior indicated by the feedback through the difference in vibration position (such as buccal side vibration indicating bite abnormality, and lingual side vibration indicating tongue abnormality), accelerating the learning process of behavior correction.

[0022] The present application will be further described in conjunction with the specific implementation. Embodiments

[0023] An intelligent bite plate system, comprising: a bite plate body; a sensor module comprising a first pressure sensor array and a second pressure sensor array mounted on the bite plate body, the first pressure sensor array being configured to monitor bite force, and the second pressure sensor array being configured to monitor tongue pressure; a haptic feedback module mounted on the bite plate body and configured to provide haptic cues to a user; a control module mounted on the bite plate body and configured to transmit and process signals, the first pressure sensor array and the second pressure sensor array being communicatively connected to an input of the control module, and the haptic feedback module being communicatively connected to an output of the control module.

[0024] By integrating bite force and tongue pressure dual monitoring, comprehensive monitoring and real-time intervention are achieved. The system can comprehensively capture two main abnormal oral behaviors (bruxism / teeth clenching and abnormal tongue) that lead to TMD aggravation. Combined with haptic feedback, real-time closed-loop treatment from "perception" to "intervention" is achieved, breaking through the limitations of traditional bite plates that only have physical isolation but no behavior correction function. By integrating the sensing, feedback, and control modules on the bite plate body, system integration and miniaturization are achieved, forming an independent, wearable integrated device that greatly improves patient comfort and daily use convenience, laying the foundation for long-term, unobtrusive home monitoring and treatment. By setting the control module, the foundation for intelligent treatment is laid, allowing simple sensor signals to be processed, analyzed, and made into intelligent decisions, providing core hardware support for subsequent algorithm optimization, personalized threshold setting, and other advanced functions.

[0025] The control module comprises a control unit (MCU), a wireless communication unit for communicating with the terminal device and / or the cloud server, and a power supply unit for powering the sensor module, the tactile feedback module, the control unit, and the wireless communication unit; the sensor module, the tactile feedback module, and the wireless communication unit are respectively in communication connection with the control unit; the terminal device is used to display a visual chart about the data collected by the sensor module in real time, and receive the user input for configuring and updating the judgment threshold and the feedback parameter of the control module; the cloud server is used to store the trend report reflecting the frequency and intensity change of the user's excessive bite force. Through wireless communication, the doctor can remotely view the data and adjust the treatment parameters (such as threshold), and the patient does not need to frequently return to the hospital, thereby improving the treatment efficiency and accessibility. The doctor can remotely and individually adjust the judgment threshold and the feedback parameter according to the real-time data and long-term trend of each patient, realize the "tailor-made" dynamic treatment scheme, avoid one-size-fits-all, and improve the curative effect. The introduction of the cloud server enables the system to store and analyze long-term data, generate a trend report, thereby quantifying the rehabilitation progress, and providing an objective and data-based basis for the doctor to evaluate the treatment effect, predict the disease development, and adjust the long-term treatment strategy.

[0026] The power supply unit comprises a battery and a charging module, and the charging module can be charged repeatedly.

[0027] The first pressure sensor array is embedded in the occlusal surface of the molar area of the bite plate body, and the second pressure sensor array is embedded in the lingual side of the lower anterior teeth of the bite plate body. The bite force monitoring point is arranged in the molar area (the main force bearing area of the bite force), and the lingual pressure monitoring point is arranged in the lingual side of the lower anterior teeth (the typical action point of the abnormal tongue protrusion behavior), so that the collected signals can best reflect the target abnormal behavior, and the monitoring accuracy and effectiveness are improved; the layout scheme enables the sensors to be located in the functional area, and avoids interference with the normal occlusion of teeth and the normal activity of the tongue, thereby maximizing the wearing comfort under the premise of ensuring the function.

[0028] The tactile feedback module comprises at least one resonance motor, which is installed on the buccal side of the molar area of the bite plate body and / or the lingual side area of the bite plate body. The resonance motor has the characteristics of fast starting, soft vibration, and low energy consumption, can provide a private feedback that only the wearer himself can clearly perceive and does not attract attention, and is very suitable for use in social occasions or sleep. The feedback device is arranged on the buccal side of the molar area and the lingual side area, so that the user can more intuitively and quickly understand the type of abnormal behavior indicated by the feedback through the difference in vibration position (such as buccal side vibration indicating occlusion abnormality, and lingual side vibration indicating tongue protrusion abnormality), thereby accelerating the learning process of behavior correction.

[0029] The occlusal plate body is covered with a resin cover layer, and a stainless steel sheet is arranged between the resonance motor and the resin cover layer. The resin cover layer completely isolates the electronic components from the oral environment, ensuring the biological safety and sealing of the system, and preventing saliva from eroding. At the same time, it also plays a role in smoothing the surface and improving comfort. Adding a stainless steel sheet as a vibration diffusion plate can effectively convert the local strong vibration of the resonance motor into a larger area, more gentle but more perceptible vibration field, solving the problem of weak vibration perception caused by the small size of the micro motor, and greatly optimizing the user experience. It should be noted that after encapsulation by the resin cover layer, it can also be coated with paraffin or epoxy for further system protection.

[0030] Among them, the first pressure sensor array and the second pressure sensor array are both flexible pressure film sensor arrays, which are light and thin and can be bent, and can be applied to curved surface measurement and can be adjusted to different shapes as needed.

[0031] In implementation, the flexible pressure film sensor array collects pressure, and through the conduction process of circuit voltage division + low noise operational amplifier + multiplexer (MUX) → analog-to-digital converter (ADC), the signal received by the sensor module is conducted to the control module for processing.

[0032] It should be noted that the first pressure sensor array and the second pressure sensor array can also be capacitive flexible pressure sensor arrays, which have high sensitivity and stability and can accurately detect the pressure on the corresponding side. Embodiment

[0033] This embodiment is similar to Embodiment One, except that the first pressure sensor array is arranged on the molar area of each side of the occlusal plate body, and the resonance motor is arranged in the installation cavity arranged on the lingual side of the lower anterior tooth of the occlusal plate body and the buccal side of the molar area of each side of the occlusal plate body. By arranging the customized installation cavity, the resonance motor can be perfectly embedded in the occlusal plate body, avoiding the formation of a prominent protrusion in the oral cavity, minimizing the foreign body sensation, protecting the oral soft tissue, and improving the feasibility of long-term wear. The installation cavity provides a stable fixing base for the resonance motor, which helps the vibration energy to be more efficiently transmitted to the occlusal plate body and the oral tissue, ensuring that the feedback signal is clear and distinguishable.

[0034] In this embodiment, the resonance motor is arranged on the buccal side of the molar area of each side of the occlusal plate body, and the first pressure sensor array on each side can detect the pressure of the molar area on each side of the occlusal plate body, for subsequent judgment of whether the corresponding side is abnormal and intervention when abnormal.

[0035] In the manufacture of the bite plate body, first, the dental arch data of the upper and lower jaws of the patient is obtained through oral scanning. The patient's bilateral posterior dental area is placed with cotton rolls, and the muscles are gently occluded to obtain a stable and comfortable centric relation position after muscle de-programming. The mechanical face bow is positioned, the data is transferred to the digital virtual jaw frame, and the bite plate worn by the lower dental arch is designed digitally. The material of the bite plate body is resin material, and the thickness of the jaw pad is generally 2-3mm.

[0036] The manufacturing process of the flexible pressure film sensor includes: selecting a 25-micron-thick polyimide (PI) film as a flexible substrate; improving the surface performance through plasma cleaning; dispersing carbon nanotubes (CNTs) in a solvent, uniformly ultrasonic, and then coating the conductive composite material on the flexible substrate by spraying, spin coating and screen printing process; coating a conductive polymer to make an electrode; covering another layer of flexible film (such as PDMS) to protect the sensitive layer and avoid environmental interference while maintaining flexibility.

[0037] The preparation process of the resonance motor includes: selecting an ultra-thin flat linear resonance motor (LRA), with a diameter of about 1 cm and a thickness of about 3 mm, and bonding at the corresponding position by resin material. The start and stop of the LRA are very fast and sensitive. Buccal side of molar area: embed the LRA in the buccal side flange area of the bite plate, i.e. close to the buccal mucosa of the molar area, avoiding the occlusal surface. The vibration here will be transmitted to the buccal mucosa, which can be perceived by the patient; lower anterior teeth lingual side: place the LRA in the lingual side of the lower anterior teeth, close to the tongue tip but need to reserve a protective layer to prevent direct contact with the tongue surface; installation cavity of molar area buccal side: length x width x height is 14mm x 8mm x 3.5mm. Lower anterior lingual side installation cavity: length x width x height is 10mm x 4.5mm x 2.8mm, and 1mm resin covering layer is reserved on the top to transmit tactile sensation. The actual thickness of the flat linear resonance motor is designed according to the actual thickness of the flat linear resonance motor. A stainless steel sheet is added between the bite plate body reserved space and the resonance motor to enhance the diffusion ability of vibration.

[0038] The embodiment realizes comprehensive monitoring and real-time intervention by integrating bite force and tongue pressure double monitoring. The system can comprehensively capture two main abnormal oral behaviors (bruxism / tight bite and abnormal tongue) that cause TMD aggravation. Combined with tactile feedback, the system realizes real-time closed-loop treatment from "perception" to "intervention", breaking the limitation of traditional bite plate which only has physical isolation but no behavior correction function. The sensing, feedback and control modules are all integrated on the bite plate main body, realizing high integration and miniaturization of the system, forming an independent and wearable integrated device, greatly improving the comfort and convenience of daily use of patients, and laying a foundation for long-term and unobtrusive home monitoring and treatment. By setting the control module, the foundation of intelligent treatment is laid, so that simple sensor signals can be processed, analyzed and made into intelligent decisions, providing core hardware support for subsequent algorithm optimization, personalized threshold setting and other advanced functions; through wireless communication, doctors can remotely view data and adjust treatment parameters (such as threshold), and patients do not need to visit the doctor frequently, improving treatment efficiency and accessibility. Doctors can remotely and individually adjust the judgment threshold and feedback parameters according to the real-time data and long-term trends of each patient, realize the "tailor-made" dynamic treatment plan, avoid one-size-fits-all, and improve the treatment effect. The introduction of the cloud server enables the system to store and analyze long-term data, generate trend reports, and thus quantify the rehabilitation progress, providing objective and data-based basis for doctors to evaluate treatment effect, predict disease development and adjust long-term treatment strategy; the resonant motor has the characteristics of fast start, soft vibration and low energy consumption, and can provide a private feedback that only the wearer can clearly perceive, which is not noticeable and very suitable for use in social occasions or sleep. By setting the feedback device on the buccal side and the lingual side of the bruxism area, the user can more intuitively and quickly understand the type of abnormal behavior indicated by the feedback through the difference in vibration position (such as buccal side vibration indicating occlusal abnormality and lingual side vibration indicating tongue abnormality), accelerating the learning process of behavior correction. Embodiment

[0039] The application also provides a method for detecting and intervening abnormal oral behaviors, which adopts the bite plate system of embodiment one or embodiment two, as shown in Figure 1 The method comprises the following steps: S1, real-time acquisition of the intraoral pressure signal of the user by the sensor module; S2, processing and feature extraction of the acquired pressure signal by the control module to obtain feature values including bite force and tongue pressure; S3, comparison of the feature values with the preset threshold values, and when the feature values exceed the corresponding preset threshold values, the tactile feedback module provides real-time tactile intervention to the user.

[0040] The tactile feedback module comprises resonance motors arranged on the lingual side of the lower anterior teeth of the bite plate body and the buccal side of the molar area on both sides of the bite plate body; in step S3, the process of the tactile feedback module providing real-time tactile intervention to the user is as follows: When the occlusal force characteristic value exceeds the preset occlusal force threshold value, it is determined that the vertical occlusal force is abnormal, and the resonance motors arranged on the buccal side of the molar area on both sides of the bite plate body are controlled to vibrate simultaneously; When the tongue pressure characteristic value exceeds the preset tongue pressure threshold value, it is determined that the tongue pressure is abnormal, and the resonance motor arranged on the lingual side of the lower anterior teeth of the bite plate body is controlled to vibrate.

[0041] By designing different vibration positions (both sides simultaneously vs. lingual side single point) for "occlusal abnormality" and "tongue pressure abnormality", the user can intuitively distinguish the current error behavior type without thinking, greatly improving the efficiency and accuracy of behavior retraining. The simultaneous vibration of both sides prompts the occlusal abnormality, which is consistent with the physiological characteristics of bilateral coordination of occlusal behavior itself; while the targeted lingual vibration directly points to the occurrence site of abnormal behavior, which is consistent with intuitive cognition and helps the brain quickly establish the cause-and-effect relationship between "behavior-feedback".

[0042] In step S3, in addition to determining that the vertical occlusal force is abnormal, the time for which the occlusal force characteristic value exceeds the preset occlusal force threshold value also needs to exceed the preset first time threshold value; in addition to determining that the tongue pressure is abnormal, the time for which the tongue pressure characteristic value exceeds the preset tongue pressure threshold value also needs to exceed the preset second time threshold value. This can effectively filter out transient signals generated by normal physiological activities such as swallowing, coughing, speaking, or accidental tooth collision, ensuring that the system only intervenes when a continuous, pathologically significant abnormal behavior is detected, thereby improving the reliability and professionalism of the system and avoiding user frustration or abandonment of treatment due to frequent false positives.

[0043] The control module further comprises a wireless communication unit in communication with a terminal device and / or a cloud server, which utilizes the terminal device to display a visual chart of the data collected by the sensor module in real time, and receives user input for configuring and updating the judgment threshold and feedback parameters of the control module, and / or utilizes the cloud server to store a trend report reflecting changes in the frequency and intensity of the user's occlusal force exceeding the standard, to quantify the progress of rehabilitation.

[0044] By deeply integrating the treatment method with digital management, it is not only an isolated treatment device, but also a digital medical platform connecting doctors and patients. The overall business model of "device + service" is realized, ensuring the comprehensive effect of remote monitoring, personalized adjustment, and quantitative evaluation.

[0045] In this embodiment, a multimodal biofeedback system is constructed using a sensor module. When in use, the biofeedback system establishment process includes: data acquisition, signal conditioning, feature extraction and threshold judgment, tactile feedback decision-making, data encapsulation and transmission, and cloud / mobile visualization and analysis.

[0046] The specific working principle is as follows: Data Acquisition and Signal Conditioning 1) The sensor module detects the pressure signal, converts it into a digital signal through a microchip, and outputs an analog voltage signal. That is, the MCU of the control module reads the raw voltage values ​​of all sensor channels in a loop at a certain sampling rate (such as 100-200Hz) through an analog-to-digital converter (ADC).

[0047] 2) The raw voltage signal may contain high-frequency noise (such as muscle tremors and circuit noise). The low-noise instrumentation amplifier improves the signal-to-noise ratio. The control module retains the effective pressure change trend. After calibration and normalization, the ADC reading is converted into a standardized pressure physical quantity. It can also calculate the asymmetry index (AI) based on the signals from both molar regions to ensure that the data from all sensor channels are synchronized in time, providing a consistent timestamp for subsequent analysis.

[0048] (2) Feature extraction and real-time judgment (the core algorithm runs on the MCU of the control module) 1) Feature extraction: Bite force calculation: The total bite force at the current moment is obtained by weighting the readings of all sensors in the molar area. ; Tongue pressure pattern analysis: monitoring the pressure values ​​of the tongue side sensor .

[0049] 2) Threshold judgment and feedback decision: The MCU of the control module will calculate in real time Compared with the dentist's preset bite force threshold Compare and calculate the pressure values ​​from the tongue-side sensor. To determine whether it continuously exceeds the tongue pressure threshold within a specific time period. (This indicates that the patient is abnormally pressing their teeth against the ground.) , These all represent the critical forces considered potentially capable of causing damage. If... If this is detected, it indicates excessive vertical biting force, and the resonant motors on both sides are immediately activated simultaneously, providing a 50-100ms pulse alert; if If this is detected, it is determined to be abnormal tongue pressure, and the resonant motor on the lingual side of the lower anterior teeth is activated, providing a pulse prompt of 50-100ms.

[0050] Anti-jitter processing: To avoid false trigger caused by transient disturbance (e.g. sudden cough or swallow), the requirement is and the corresponding threshold must be exceeded and last for a certain time (e.g. 100ms) to confirm the trigger.

[0051] 3) Data packaging and wireless transmission: The data packaging content needs to be adjusted, focusing on the transmission of the value. At the same time, the real-time data frame contains: the data collected by the sensor module, the calculated real-time feature values (including , and the rate of change of total bite force over time ), event flags (0: no event; 1: triggered by excessive bite force; 2: triggered by tongue pressure).

[0052] 4) Data processing and presentation of terminal device and cloud server: Terminal device: Real-time visualization: heat map: used to display the distribution of force, helping doctors determine whether the force is concentrated on an abnormal point. Statistical chart: time series curve chart: Y axis is the total bite force . A curve shows the change, and a clear reference line marks , and each feedback event is marked on the curve. Column chart / statistical panel: shows the number of times the total bite force exceeds the threshold, the cumulative duration, the maximum bite force value, etc. during this wearing period.

[0053] Parameter configuration: the core parameters set by the doctor remotely are: bite force threshold , feedback mode (such as pulse intensity, mode) and tongue pressure threshold .

[0054] Cloud server: Long-term trend analysis report mainly shows the frequency and intensity changes of the patient's daily / weekly bite force exceeding the standard, quantifying the progress of rehabilitation.
