Description

Technical Field

[0001] This invention mainly relates to the fields of oral temporomandibular joint and orthodontic clinical treatment technology, specifically a soft and elastic occlusal plate for real-time monitoring of occlusal force. Background Technology

[0002] Temporomandibular joint disorder (TMD) is a common oral and maxillofacial disease, and one of the four most prevalent oral diseases in clinical practice. It commonly affects young adults, particularly women, with the highest incidence rate between 20 and 30 years of age, ranging from 28% to 88%. The main symptoms of TMD include abnormal mandibular movement, joint pain, clicking or crepitus sounds, and some patients may also experience headaches, ear symptoms, and even neck and shoulder pain.

[0003] Traditional occlusal splints are unsuitable for measuring occlusal forces and have limited effectiveness in cushioning and releasing excessive occlusal forces. They fail to effectively reduce traumatic stress on teeth and periodontal tissues, potentially leading to further damage. During occlusal force measurement, teeth may experience minute movements, resulting in inaccurate data. This instability not only affects the accuracy of occlusal force monitoring but may also mislead clinical diagnosis. Furthermore, the oral cavity is the beginning of the digestive tract, with primary functions including chewing, sucking, swallowing, speech, sensation, facial expressions, food intake, and respiration. The oral environment is complex; therefore, intraoral devices need to consider effective cleaning mechanisms. The complex structure on the inner side of the occlusal splint easily accumulates saliva and food debris, leading to bacterial growth. Summary of the Invention

[0004] The present invention mainly provides a soft and elastic bite plate for real-time monitoring of bite force, in order to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A soft elastic occlusal plate for real-time monitoring of occlusal force includes a personalized jaw plate. Both ends of the personalized jaw plate are provided with fixing grooves, and multiple placement grooves are provided inside each of the two fixing grooves. A pressure sensing component is embedded inside each placement groove, and a connecting groove is provided on one side of each placement groove. A signal transmission component is electrically connected to one side of the pressure sensing component. The personalized jaw plate has a patch assembly on its inner side.

[0006] Preferably, the personalized jaw plate is made of materials including but not limited to methacrylate resin, silicone and polyetherketone, and both rear ends of the personalized jaw plate are arc-shaped.

[0007] Preferably, the inner wall surface of the fixing groove is smooth, and its depth is in the range of 1 / 3 to 1 / 2 of the tooth surface on the personalized jaw plate surface.

[0008] Preferably, the pressure sensing component includes a pressure sensor and a pressure sensing plate. The pressure sensor is embedded inside the placement slot, and pressure sensing plates are fixedly installed at both ends of the pressure sensor.

[0009] Preferably, each of the two pressure sensing plates is fixedly connected to a placement block on both sides, and the placement block has an elastic plate inside, and a fixing plate is fixedly connected to one side of the elastic plate.

[0010] Preferably, the fixing piece has an arc-shaped structure, and the curvature of the fixing piece matches the shape of the inner cavity of the placement block. The fixing piece is made of polyurethane elastomer, and its elastic modulus ranges from 0.5 MPa to 1 MPa.

[0011] Preferably, the signal transmission component includes a fixed resistor, an operational amplifier chip, a microcontroller, a Bluetooth module, and a power module. The pressure sensor is connected to a fixed resistor on one side, and an operational amplifier chip is connected to another side of the fixed resistor. The operational amplifier chip is connected to a microcontroller on one side, and a Bluetooth module is connected to another side of the microcontroller. The power module is fixedly connected to the bottom of the Bluetooth module.

[0012] Preferably, the patch assembly includes a positioning patch and a cleaning patch, with the positioning patch attached to the inner side of the personalized jaw plate and the cleaning patch attached to the inner side of the positioning patch.

[0013] Preferably, the limiting sheet is made of medical-grade polypropylene and has a thickness of 3mm to 5mm, and the cleaning sheet is made of hydrophilic polyurethane foam and has a thickness of 0.5mm to 1mm.

[0014] Preferably, the microcontroller is an ESP32, the Bluetooth module is an HC-05, and the Bluetooth module is connected to the microcontroller's serial communication interface.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the design of the fixed plate and the elastic plate, the teeth are stably fixed. The patient places the personalized jaw plate in the mouth, aligning the upper and lower teeth with the fixed slot and fitting tightly. When biting, the teeth apply pressure to the fixed plate, pushing it to one side and squeezing the elastic plate. The elastic plate generates a counter-elastic force, which interacts with the force applied by the teeth to form a balance state, firmly fixing the teeth to the top of the pressure sensing plate. This effectively prevents the teeth from moving during biting, ensuring the accuracy and reliability of the measurement data. It not only improves the accuracy of bite force monitoring but also enhances the user's wearing comfort and stability, providing a reliable basis for clinical diagnosis and having significant practical value and clinical significance.

[0016] 2. The personalized jaw plate closely conforms to the occlusal surfaces of the upper and lower teeth, providing a clinical function of buffering and releasing excessive occlusal forces, reducing traumatic stress on the teeth and periodontal tissues. At the same time, several pressure sensors monitor the occlusal forces between the upper and lower teeth in different positions in the oral cavity in real time, and record and transmit the occlusal forces for analysis of occlusal forces in different areas, providing a basis for clinicians to diagnose and treat diseases such as bruxism and temporomandibular joint disorder.

[0017] 3. The use of patch components significantly improves the performance and user experience of the occlusal plate. The limiting patch is made of medical-grade polypropylene with a thickness of 3mm to 5mm. It is directly attached to the inside of the personalized occlusal plate, which not only enhances the overall strength and stability of the occlusal plate, but also ensures its long-term safety and biocompatibility in the oral environment, without causing irritation or damage to oral tissues. The inner cleaning patch is made of hydrophilic polyurethane foam with a thickness of 0.5mm to 1mm, which can effectively absorb saliva in the oral cavity, keep the inside of the occlusal plate clean and dry, and reduce the possibility of bacterial growth.

[0021] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete. Example

[0022] Please refer to the appendix carefully. Figure 1 , 23, 4, 5, 7, A soft, elastic occlusal plate for real-time monitoring of occlusal force, comprising a personalized occlusal plate 1. The personalized occlusal plate 1 is made of materials including, but not limited to, methacrylate resin, silicone, and polyetherketone. These materials not only have good biocompatibility but also possess appropriate elasticity and strength. Furthermore, the rear ends of both sides of the personalized occlusal plate 1 are curved to better conform to the user's oral contour, improving wearing comfort and stability. Fixing grooves 2 are provided at both ends of the personalized occlusal plate 1. The inner wall surface of the fixing grooves 2 is smooth, and their depth is between 1 / 3 and 1 / 2 of the tooth surface on the personalized occlusal plate 1. This design ensures that the teeth are securely embedded in the fixed slots 2 without causing excessive pressure, thus enabling accurate monitoring of occlusal force without affecting the biting function. Both fixed slots 2 have multiple placement slots 3, and each placement slot 3 is embedded with a pressure sensing component 4. The pressure sensing component 4 monitors the magnitude of the occlusal force in real time. The pressure sensing component 4 includes a pressure sensor 401 and a pressure sensing plate 402. The pressure sensor 401 is embedded in the placement slot 3, and pressure sensing plates 402 are fixedly installed at both ends of the pressure sensor 401. The pressure sensing plates 402 transmit the occlusal force... The force is evenly transmitted to the pressure sensor 401, while avoiding direct contact between the pressure sensor 401 and the patient's teeth to prevent saliva from affecting the accuracy of the biting force. Placement blocks 8 are fixedly connected to both sides of the two pressure sensing plates 402, and each placement block 8 contains an elastic plate 9. A fixing plate 10 is fixedly connected to one side of each elastic plate 9. The fixing plate 10 has an arc-shaped structure, and its curvature matches the shape of the inner cavity of the placement block 8. The fixing plate 10 is made of polyurethane elastomer with an elastic modulus ranging from 0.5 MPa to 1 MPa. This elastic modulus setting ensures that the elastic plate 9 can withstand force... It can generate appropriate deformation, thereby providing a stable reaction force for the fixation plate 10. At the same time, it can quickly return to its original shape after the biting force disappears. When the user bites, the teeth will apply pressure to the fixation plate 10, pushing the fixation plate 10 to one side and squeezing the elastic plate 9. After being squeezed, the elastic plate 9 will generate a reverse elastic force, which interacts with the force applied by the teeth to form a balance. This balance can firmly fix the teeth on the top of the pressure sensing plate 402, effectively preventing the teeth from moving during biting, thereby ensuring the accuracy and reliability of the measurement data.

[0023] Please refer to the appendix carefully. Figure 5 , 6A connection slot 5 is provided on one side of the placement slot 3 for placing the signal transmission component 6. The signal transmission component 6 is electrically connected to one side of the pressure sensing component 4. It is used to process, amplify, and convert the bite force signal collected by the pressure sensing component 4, and finally transmit it to an external device wirelessly. The signal transmission component 6 includes a fixed resistor 601, an operational amplifier chip 602, a microcontroller 603, a Bluetooth module 604, and a power module 605. The fixed resistor 601 is connected to one side of the pressure sensor 401. Its main function is to form a voltage divider circuit with the pressure sensor 401. When the pressure sensor 401 is subjected to bite force, its resistance value changes, which causes a change in the voltage output of the voltage divider circuit. This voltage change is the basis for subsequent signal processing. The operational amplifier chip 602 is connected to one side of the fixed resistor 601. Its main function is to amplify the weak voltage signal output by the voltage divider circuit. Through the amplification effect of the operational amplifier chip 602, the signal can be boosted to a suitable voltage range for subsequent processing. The conversion is performed by an ESP32 microcontroller 603 connected to the output of the operational amplifier chip 602. Its main function is to convert the amplified analog voltage signal into a digital signal. The ESP32 has a built-in analog-to-digital converter (ADC), which can accurately convert analog signals into digital signals for further data processing and transmission. The Bluetooth module 604 is an HC-05 model. The Bluetooth module 604 is connected to the microcontroller 603 via a serial communication interface (such as UART). The microcontroller 603 sends the converted digital signal to the Bluetooth module 604 via the serial communication interface. The Bluetooth module 604 then transmits this data wirelessly to external devices (such as mobile phones or PC applications). The power module 605 provides stable power support for the entire signal transmission assembly 6. It is connected to the bottom of the Bluetooth module 604 to ensure that all electronic components (including the pressure sensor 401, operational amplifier chip 602, microcontroller 603, and Bluetooth module 604) receive the required power.

[0024] Please refer to the appendix carefully. Figure 1 , 2 The personalized jaw plate 1 has a patch assembly 7 on its inner side. The patch assembly 7 includes a limiting piece 701 and a cleaning piece 702. The limiting piece 701 is directly attached to the inner side of the personalized jaw plate 1 to improve the overall strength of the personalized jaw plate 1. The cleaning piece 702 is attached to the inner side of the limiting piece 701. The cleaning piece 702 mainly absorbs saliva in the oral cavity, keeping the inner side of the personalized jaw plate 1 clean and dry, reducing the possibility of bacterial growth. The limiting piece 701 is made of medical-grade polypropylene, ensuring that it will not cause irritation or damage to oral tissues during long-term use in the oral environment. The limiting piece 701 is 3mm to 5mm thick. The cleaning piece 702 is made of hydrophilic polyurethane foam and is 0.5mm to 1mm thick. The specific operation method of this invention is as follows: During use, the user first places the personalized jaw plate 1 inside the mouth, ensuring that the upper and lower teeth are accurately aligned with the fixed slot 2, and that the bottom of the upper and lower teeth fit tightly against the bottom wall of the fixed slot 2. When the user bites, the teeth apply pressure to the fixed plate 10, pushing the fixed plate 10 to one side, while simultaneously squeezing the elastic plate 9. The elastic plate 9 generates a counter-elastic force after being squeezed, interacting with the force applied by the teeth to form a balanced state. This balance can firmly fix the teeth on the top of the pressure sensing plate 402, effectively preventing the teeth from moving during biting, thereby ensuring the accuracy and reliability of the measurement data. The pressure sensing plates 402 at both ends of the pressure sensor 401 can sense the magnitude of the biting force in real time. When the biting force acts on the pressure sensing plate 402, the pressure sensor 402... Force sensor 401 converts biting force into a corresponding voltage signal. Fixed resistor 601 is connected in series with pressure sensor 401 to form a voltage divider circuit. When the biting force changes, causing the resistance value of pressure sensor 401 to change, the voltage divider circuit outputs a corresponding, changing voltage signal. The voltage signal is amplified by operational amplifier chip 602 and then transmitted to microcontroller 603. Microcontroller 603 converts the analog voltage signal into a digital signal, which is then wirelessly transmitted to a mobile application on a mobile phone or PC via Bluetooth module 604. This data can be used by clinicians for the diagnosis and treatment of diseases such as bruxism and temporomandibular joint disorder, providing doctors with scientific and accurate evidence to help them better formulate treatment plans and improve treatment outcomes.
