[0002] With the development of science and technology, orthodontic technology is moving towards a more intelligent and precise direction. Traditional braces only provide physical correction, and current braces all use traditional dental braces. There is no way to obtain the pressure applied by the braces on the teeth. During the process of dental correction, it is very important to monitor and obtain the pressure applied by the braces on the teeth. Orthodontics at different stages may require different pressure sizes and distributions. Obviously, current dental braces do not have the ability to provide real-time pressure data to help with more effective correction. Traditional orthodontic methods rely on experience judgment and regular visits to the dentist to adjust the braces. Therefore, there is currently a lack of a device for obtaining pressure signals on braces to achieve intelligence. Utility Model Content

[0009] A photoelectric film is also embedded on the top surface of the second flexible electrode, and the photoelectric film is connected to the first flexible electrode through a flexible FPC;

[0010] The photoelectric film is in contact with the inside of the tooth socket of the dental brace, and is arranged on the inner wall of the front end of the tooth socket to receive the incident light source.

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1 As shown, it is a schematic diagram of the structure of the pressure data acquisition device of the utility model. The utility model is a pressure data acquisition device for wearable braces, comprising: a pressure sensitive unit and a signal output unit packaged on the braces body;

[0031] The pressure sensitive unit is used to obtain the electrical signal generated by the pressure change between the braces body and the teeth in real time, and send it to the terminal device through the signal output device;

[0032] The signal output unit is used to measure the electrical signal of the pressure response of the pressure sensitive unit and perform preprocessing, and then send the converted digital signal to the smart terminal device, so that the pressure sensitive unit can communicate wirelessly with the smart terminal device outside the oral cavity through the signal output device.

[0033] like Figure 2 to Figure 4 As shown, there are multiple structural views of the pressure sensitive unit of the utility model and a manufacturing flow chart thereof, the pressure sensitive unit comprises: a first flexible substrate 1, a first flexible electrode 2, a dielectric film 3, a second flexible electrode 4, and a second flexible substrate 5;

[0034] The first flexible electrode 2 and the second flexible electrode 4 are respectively embedded on the first flexible substrate 1 and the second flexible substrate 5 to form an integrated structure.

[0035] A dielectric film 3 is sandwiched between the first flexible substrate 1 and the second flexible substrate 5; and the upper and lower surfaces of the dielectric film 3 are attached to the top surface of the first flexible electrode 2 and the bottom surface of the second flexible electrode 4 respectively;

[0036] A photoelectric film 6 is also embedded on the top surface of the second flexible electrode 4, and the photoelectric film 6 is connected to the first flexible electrode 2 through a flexible FPC 7, which is equivalent to the positive and negative poles of the photoelectric film being connected to the first and second flexible electrodes respectively, to supply power to the pressure sensitive unit and the signal output unit.

[0037] The photoelectric film 6 is in contact with the inside of the tooth socket of the wearable orthodontic braces, and the photoelectric film 6 is arranged at the inner wall of the front end of the tooth socket to receive the incident light source.

[0038] like Figure 3 As shown, the size of the first flexible electrode 2 is the same as the size of the second flexible electrode 4;

[0039] The length of the dielectric film 3 is greater than that of the first flexible electrode 2 or the second flexible electrode 4 , and the upper and lower surfaces of the dielectric film 3 are respectively covered on the first flexible electrode 2 and the second flexible electrode 4 .

[0040] The first flexible electrode 2 and the second flexible electrode 4 are both electrode patches made of conductive metal, or three-dimensional network structure electrodes with conductive nanoparticles or nanowires loaded on melamine materials. In this embodiment, three-dimensional network structure electrodes are used.

[0041] The first flexible substrate 1 and the second flexible substrate 5 are both substrates of a material, and the first flexible substrate 1 and the second flexible substrate 5 are the same in size.

[0042] The dielectric film 3 is a polymer material containing at least one of polydimethylsiloxane, polyurethane, polyimide, and polyvinyl alcohol, or at least one fluorine-containing polymer material, or a composite of the dielectric film 3 as a matrix material and one or more ceramic phase and conductive phase materials.

[0043] The surface of the dielectric film 3 is provided with a microstructure using natural materials such as wood or sandpaper as a template; wherein the microstructure is a micro-nanostructure array composed of any one of a dome, a pyramid, and a cylinder. The effect of the micro-nanostructure array is as follows: Figure 5 As shown;

[0044] like Figure 1 As shown, there are multiple pressure sensitive units, and the shape and size of each pressure sensitive unit are the same as the shape and size of the force-bearing area of ​​the brace body.

[0045] A plurality of pressure sensitive units are distributed between the tooth surface and the inner surface of the braces through the first flexible substrate 1 and the second flexible substrate 5, and are arranged at various pressure points of concern in orthodontics;

[0046] When the first flexible substrate 1 or the second flexible substrate 5 is squeezed, the electrode and the dielectric film 6 are deformed or the electrical performance parameters are changed, which causes the change of the electrical signal and is sent to the smart terminal device through the signal output device to complete the collection of tooth force data.

[0047] The working principle of the utility model is as follows:

[0048] When the user is wearing the braces, the braces will exert force on the teeth. The force will decrease over time, and the pressure collection device will respond to the pressure change and generate a pressure signal.

[0049] When the pressure acquisition device acquires the pressure signal, the photoelectric film 6 receives the light source in real time, and the positive and negative electrodes of the photoelectric film are respectively connected to the first and second flexible electrodes to supply power to the pressure sensitive unit and the signal output unit.

[0050] The pressure sensitive unit converts the pressure signal into an electrical signal and sends it to the signal output unit; the signal output unit converts the received pressure analog signal into a digital signal and transmits it to the terminal device for data processing, thereby completing the collection of pressure data.

[0051] In summary, the utility model embeds flexible sensors in transparent orthodontic braces to monitor the force on the corrected teeth in real time. There is no need for a follow-up visit with a doctor, only regular testing of the force on the teeth is required, thereby shortening the correction period and reducing costs, and solving the instability caused by wearing traditional braces.

[0052] The above description is only an implementation method of the utility model and is not intended to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, expansion, etc. made within the spirit and principle of the utility model are included in the protection scope of the utility model.
