The occlusal force measuring device is a measuring device formed by combining a wireless transmission technology with a pressure sensor and a pressure measuring module and is used for measuring the occlusal force between teeth. In particular, the bite force measuring device comprises at least a bite sensing piece, typically a sheet-like member, adapted to be placed in the tooth. The occlusion sensing sheet is internally provided with a pressure sensing element. When measuring the occlusal force between the teeth, the occlusal induction piece is arranged between the teeth to be measured, the pressure measuring module reads the relevant parameters from the pressure sensor, and then the data is transmitted out through the wireless transmission module coupled with the pressure measuring module. A reading device, such as a smart terminal like a computer, a mobile phone, etc. or a specially developed device, is in communication connection with the wireless transmission module to read data related to the dental occlusal force. The reading means usually comprise a display device for displaying the pressure value. When the occlusal force measuring device is used for measuring the occlusal force, the occlusal induction sheet is firstly placed between teeth to be measured, the wireless transmission module transmits data measured by the pressure sensor, and then the reading device demodulates the received data to obtain a pressure value. The implementation of the wireless transmission technology in the present application can be implemented in various ways, including but not limited to RFID technology, bluetooth technology, ZigBee technology, and WIFI technology. The occlusion force measuring device is very convenient to use, safe, reliable and long in service life.
Fig. 1-3 show schematic views of an application of an occlusion force measuring device according to an embodiment of the application from different view angles, respectively. The bite force measuring device 100 includes a bite sensing piece 110, a pressure measuring module 120, and a wireless signal transmission module 130. Wherein the occlusion sensing piece 110 has a thin sheet shape and can be placed between the upper and lower teeth. The engagement sensor sheet 110 may be an ultra-thin flexible printed circuit board, the thickness of which can be as thin as 0.1mm, and can be made into different models as required, as shown in fig. 4. For example, when used to measure full-mouth bite force, the bite-sensing piece 110 can be an arched sheet that conforms to the shape of the dental arch; when measuring the biting force of a single tooth or a partial row, the biting-in sensing chip 110 may be a strip-shaped sheet. The occlusion sensing piece 110 has pressure sensors 111 arranged longitudinally and transversely in a film so as to be able to accurately measure the magnitude and distribution of the occluding force between teeth. The engagement sensing piece 110 can be repeatedly used and still maintain high reliability. Each pressure sensor 111 has an electrical parameter that varies with ambient pressure. For example, the pressure sensor 111 may be a piezoresistive pressure sensor, the resistance value of which changes significantly with changes in mechanical deformation. When the pressure sensor 111 is deformed under pressure, the pressure to be measured can be obtained by measuring the resistance value of the piezoresistive pressure sensor and then according to the corresponding relationship between the resistance value and the pressure. According to the measured pressure and the pressure distribution, the occlusal force and the occlusion state between the upper and lower teeth can be obtained. Furthermore, the occlusion mechanics tracks of all directions and all point positions under the tooth occlusion motion state can be monitored and measured through real-time measurement.
The pressure measuring module 120 is used for measuring the electrical parameter of the pressure sensor 111 and calculating the pressure value according to the measured electrical parameter. In the illustrated embodiment, the load cell module 120 is formed by coupling a plurality of integrated circuit chips, but it should be understood that it may be formed by coupling discrete components. And the wireless transmission module 130 is coupled to the pressure measuring module 120 and transmits the pressure value from the pressure measuring module 120 according to the calculated pressure value. Typically, the pressure measurement module 120 is integrated with the wireless transmission module 130. The wireless transmission module 130 is connected to the engagement induction plate 110 through a wire 140. Preferably, the entire occlusion force measuring device 100 is a sheet formed of a flexible printed circuit board, and the wire 140, the occlusion sensing piece 110, and the wireless transmission module 130 and the pressure measuring module 120 are integrated in the sheet. The wireless transmission module 130 may be used to transmit the pressure value to a smart terminal, such as a cell phone. In the present invention, the wireless transmission module 130 can transmit the pressure value calculated by the pressure measuring module 120 in real time, so that the distribution of the occlusal force between the upper and lower teeth can be continuously monitored over a period of time, thereby performing orthodontic treatment.
In addition, a flexible rechargeable thin film battery 150 may be provided in the bite force measuring device 100 in order to supply power to the circuit in the bite force measuring device 100 to measure pressure and transmit the measured data. The rechargeable thin film battery 150 may have a thickness of less than about 0.5mm and may be formed in a flexible circuit board by a conventional manufacturing process.
Preferably, the engagement sensing piece 110, the pressure measuring module 120, the wireless signal transmission module 130, and the flexible rechargeable thin film battery 150 (if any) may be integrated into one flexible circuit board, and a waterproof flexible thin film is coated outside the flexible circuit board, so that the internal circuit can be protected and the sterilization process can be conveniently performed.
The bite force measurement device 100 may further comprise a reading module 160. The reading module 160 may be disposed separately from the other parts of the biting force measuring device 100, and may be capable of receiving the data transmitted by the wireless signal transmission module, and demodulating the received data to obtain the pressure value. The reading module 160 may further include a display device for displaying the pressure value. The reading module can adopt an intelligent terminal such as a computer, a mobile phone and the like.
In the embodiment shown in fig. 2, the bite force measuring device 100 is integrated in a mouthpiece in which the bite sensing piece is positioned between teeth, and the pressure measuring module 120, the wireless transmission module 130, and the rechargeable thin film battery 150 are positioned at a portion of the mouthpiece outside the teeth.
In some embodiments, the pressure measuring module 120 and the wireless transmission module 130 may be located outside the oral cavity and connected to the bite sensing piece 110 through the wires 140. Preferably, the conductive wire 140 is also disposed in the flexible printed circuit board having a long bar shape, so that the entire occlusion force measuring apparatus 100 is a sheet formed by one flexible printed circuit board, wherein the portion having the conductive wire 140 has a long bar shape, and the occlusion sensing piece 110, the wireless transmission module 130 and the pressure measuring module 120 are respectively disposed at both ends of the portion. In this case, the conductive wires 140 may be provided with a pluggable electrical connection at the connection with the extraoral portion, thereby facilitating replacement of the bite-sensing piece 110 when the bite-sensing piece 110 is damaged due to repeated use.
In a preferred embodiment, the wireless signal transmission module 130 is an RFID antenna. Among them, the RFID antenna is used for transmitting and receiving electromagnetic waves, and is a conversion device of electromagnetic waves and electrical signals, which can convert electromagnetic waves into electrical signals, or convert electrical signals into electromagnetic waves. In this embodiment, when the pressure value needs to be read, the reading module 160 is opposite to the RFID antenna, so as to send a radio frequency signal to the RFID antenna, and the RFID antenna receives the radio frequency signal and generates an induced current for supplying power to the pressure measuring module 120 and the occlusion sensing piece 110 to measure the pressure and transmit the measured data. In this case, the structure of the dental occlusion force measuring apparatus 100 can be further simplified without providing the rechargeable thin film battery 150.
In a preferred embodiment, the wireless signal transmission module 130 is an NFC antenna supporting the NFC communication standard. NFC (Near Field Communication) is a short-range high-frequency wireless Communication technology evolved from RFID technology, and the operating frequency is 13.56 MHz. NFC has lower power consumption compared to RFID technology.
Fig. 6 shows a schematic view of the load cell module 120 of fig. 1, and as shown, the load cell module 120 includes a measurement unit 121 and a control unit 123.
The measuring unit 121 is coupled to the bite sensing piece 110 for measuring an electrical parameter of the pressure sensor 111 and outputting a pressure signal. Fig. 7 shows an exemplary structure of the measurement unit 121 in fig. 6, and as shown, the pressure sensor 111 is a piezoresistive pressure sensor, and the measurement unit 121 includes resistors R1 and R2 and an analog-to-digital converter (ADC). The ADC includes two differential input terminals 121a (Vin +), 121b (Vin-) and an output terminal Vout. One end of the resistor R1 is connected to a power supply voltage (Vcc), and the other end is coupled to the positive input terminal 121a (Vin +) of the ADC; resistor R2 has one terminal coupled to Ground (GND) and the other terminal coupled to the negative input terminal 121b (Vin-) of the ADC. The pressure sensor 111 has two ends coupled to the positive input terminal 121a (Vin +) and the negative input terminal 121b (V-) of the ADC, respectively. The voltage signal between the two inputs 121a, 121b of the ADC reflects the resistance value at which the pressure sensor 111 is. The ADC may convert the voltage signal to a digitized pressure signal and output via the output terminal Vout. It is understood that the structure of the measurement unit 121 shown in fig. 6 is merely exemplary, and those skilled in the art can design different measurement circuit structures according to the type of the electrical parameter of the pressure sensor 111. The control unit 123 is coupled to the measurement unit 121 and the RFID antenna, respectively. The control unit 123 includes a logic circuit, which receives the pressure signal output by the measuring unit 121, calculates an electrical parameter of the pressure sensor 111 using the pressure signal, and transmits the measured pressure value through the RFID antenna.
Furthermore, the bite force measuring device 100 may further comprise an analyzing module (not shown) capable of receiving the pressure data from the wireless transmission module 130 or the reading module 160 and analyzing the pressure data. The analysis module may be integrated with the reading module 160, may be provided separately, or may be integrated in a smart device. The analysis module can analyze the received data and store the data in a two-dimensional picture or video form, and can display the pressure distribution on partial teeth or full teeth, so that doctors can know the occlusal force condition of patients more intuitively. According to the position information of the upper and lower teeth and the pressure distribution, the analysis module can also provide a tooth three-dimensional display model for clinically observing and researching various related oral clinical symptoms of the patient caused by the occlusion relation. According to the motion trail information of the continuously monitored pressure points, clinical data observation can be provided, and the method plays a guiding role in treatment and rehabilitation of orthodontics, pediatrics and temporomandibular joint disorder. In addition, the temporomandibular joint movement track is recorded by combining the existing jaw frame and the face bow, and an accurate joint diagram can be obtained.
The present invention also provides an oral wearing device 200, as shown in fig. 8. The oral cavity wearing apparatus 200 includes a bite pad portion 210 between upper and lower teeth, and the oral cavity wearing apparatus may include the above-described dental bite force measuring apparatus 100, in which the bite sensing piece 110 is located in the bite pad portion. In this embodiment, the bite sensing piece 110 is positioned between portions of the upper and lower dentitions after the oral cavity worn device 200 is placed in the mouth. The oral device 200 may be, for example, a jaw pad or mouthpiece that is worn on the teeth to prevent bruxism or orthodontics, but it is understood that the oral device may be other oral devices as long as bite pad portions are provided. The load cell module 120, the wireless signal transmission module 130, and the battery, etc. of the dental bite force measuring apparatus 100 may be provided in other portions of the jaw pad or the mouthpiece, for example, in a portion located at one side of the tooth (not shown).
Another embodiment 300 of an oral wearing device according to the present invention is shown in fig. 9.
