Description

Technical Field

[0001] The present invention relates to the technical field of tooth correction, and particularly to an integrated invisible orthodontic appliance for specific monitoring of oral odor, and an oral odor monitoring and orthodontic device including the same. Background Art

[0002] The bracketless invisible orthodontic appliance is a transparent device for tooth correction, also known as invisible braces. Due to its advantages of beauty, comfort and high efficiency, it is widely used in orthodontic treatment. However, the problem of oral odor often occurs during the use of the bracketless invisible orthodontic appliance, which not only affects the oral health of patients, but may also have a negative impact on their psychology and social activities. In addition, oral odor may be related to gastrointestinal diseases or systemic diseases, such as gastroesophageal reflux disease or other digestive system problems, or even diabetic ketoacidosis. Therefore, monitoring oral odor not only helps to improve oral hygiene, but also enables timely understanding of the physical health status.

[0003] The patent with the publication number CN 116138912 A discloses a dental irrigator with an oral odor detection function and its working method, which can realize oral odor detection and control the flushing intensity, flushing flow rate or flushing time according to the detection result.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. For those not specified in the embodiments, the conventional conditions or the conditions recommended by the manufacturer are followed. For the reagents or instruments not specified by the manufacturer, they are all conventional products that can be obtained through commercial purchase.

[0049] As shown in the appendix Figures 1-5 The present invention discloses an integrated oral malodor monitoring invisible aligner, including an invisible aligner main body without brackets 1 and an oral malodor detection film 2 located on the lingual and palatal outer wall surfaces of the invisible aligner main body 1.

[0050] The oral malodor detection film 2 is a ultra-thin breathable composite film layer structure, including 1 layer of signal data transmission and processing layer 26 for receiving, processing, and transmitting oral malodor monitoring data and at least 1 layer of malodor detection film layer for monitoring oral malodor; the signal data transmission and processing layer 26 is located between the malodor detection film layer and the invisible aligner main body 1, and the malodor detection film layer is connected to the signal data transmission and processing 26 layer through a micro-port.

[0051] The odor detection film layer includes at least one of the following detection layers: a volatile sulfur compound detection layer 21, an ammonia detection layer 22, a volatile organic compound detection layer 23, a ketone body detection layer 24, and an acidic gas detection layer 25;

[0052] The volatile sulfur compound detection layer 21, the ammonia detection layer 22, the ketone body detection layer 24, the volatile organic compound detection layer 23, and the acidic gas detection layer 25 are arranged in sequence from outside to inside.

[0053] The signal data transmission and processing layer 26 includes a Bluetooth module 266, at least one data processing module, a micro - circuit system 267 for powering the Bluetooth module and the data processing module, and at least one micro - port 268 for connecting the data processing module and the odor detection film layer. The Bluetooth module 266 is wirelessly connected to each data processing module.

[0054] The data processing module includes one of the following: a volatile sulfur compound data processing module 261, an ammonia data processing module 262, a volatile organic compound data processing module 263, a ketone body data processing module 264, and an acidic gas data processing module 265.

[0055] The volatile sulfur compound detection layer 21 includes a SnO 2 thin film and a micro - port 211 disposed on the SnO 2 thin film. The volatile sulfur compound detection layer 21 is used to detect volatile sulfur compounds (VSCs), such as hydrogen sulfide (H 2 S), methanethiol (CH 3 SH), etc. This layer uses a thin film made of metal oxide SnO 2 sensitive to sulfides. The preparation method of the SnO 2 thin film is prior art. In some embodiments of the present invention, the SnO 2 thin film is prepared by the sol - gel method, and the film thickness is controlled at 150 - 200 nm by spin - coating to ensure uniform distribution of the film layer and sensitive response to gases. Then, it is heat - treated at 300 °C for 1 hour to form a stable thin film. After contacting with VSCs such as H 2 S, a redox reaction occurs, resulting in changes in conductivity and color (gradually changing from transparent to gray or brown), and is transmitted through the micro - port 221 to the corresponding data processing module (volatile sulfur compound data processing module 261) in the signal data transmission and processing layer 26.

[0056] The ammonia detection layer 22 includes a flexible electrochemical sensor formed by depositing electrode materials on a flexible substrate and a micro - port disposed on the flexible electrochemical sensor. The ammonia detection layer 22 is used to detect ammonia (NH3 )。The preparation method of this flexible electrochemical sensor is a prior art, which is made by depositing electrode materials on a flexible substrate through sputtering or spraying methods. The electrode thickness is controlled to be 80 - 100 nm, and the sputtering process parameters include a sputtering power of 150 W and a sputtering time of 10 minutes to ensure the uniformity and adhesion of the electrode layer. The electrode material uses a carbon-based electrode, including a glassy carbon electrode, carbon nanotubes, graphene, etc. NH 3 An oxidation reaction occurs on the electrode surface, generating a current signal proportional to the concentration of NH 3 Through the electrode reaction, the chemical change of NH 3 is directly converted into an electrical signal, and the electrical signal is transmitted to the corresponding data processing module (ammonia data processing module 262) in the signal data transmission and processing layer 26 through a micro-port.

[0057] A selective permeable membrane covers the surface of the flexible electrochemical sensor; the selective permeable membrane is a polytetrafluoroethylene film; the thickness of the selective permeable membrane is 10 - 20 μm; it is used to prevent the interference of moisture and other impurities on the detection, and at the same time ensure that NH 3 can pass through smoothly.

[0058] The volatile organic compound detection layer 23, a molecularly imprinted polymer film, and a micro-port disposed on the molecularly imprinted polymer film. The thickness of the molecularly imprinted polymer film is 80 - 120 nm. The volatile organic compound detection layer 23 is used to detect volatile organic compounds (VOCs) produced by oral bacteria metabolism, such as acetic acid, butyric acid, etc. This layer uses molecularly imprinted polymers (MIP), and these polymers have specific adsorption ability for VOCs. When binding to the target molecule, a color change reaction (from colorless to blue or purple) is triggered, and the change in color transmits an electrical signal to the corresponding data processing module (volatile organic compound data processing module 263) in the signal data transmission and processing layer 26 through a micro-port, thereby realizing the concentration detection of VOCs. The preparation method of the molecularly imprinted polymer film is a prior art. In some embodiments of the present invention, the template polymerization method is used to prepare MIP, with acetic acid, butyric acid, etc. as template molecules, and a film with specific binding sites is formed through cross-linking polymerization. The thickness of the film layer is 80 - 120 nm to ensure high sensitivity to the target gas.

[0059] The ketone body detection layer 24 includes an acetoacetone thin film and a micro-port disposed on the acetoacetone thin film. The thickness of the acetoacetone thin film is 50 - 100 μm. The ketone body detection layer 24 is used to detect ketone bodies in the oral cavity. When the ketone body contacts the acetoacetone thin film, it quickly binds and triggers a color reaction, causing the color of the thin film to change from colorless to orange or red. The change in color transmits an electrical signal through the micro-port to the corresponding data processing module (ketone body data processing module 264) in the signal data transmission and processing layer 26. The preparation method of the acetoacetone thin film is prior art. In some embodiments of the present invention, the acetoacetone is evenly distributed on the substrate by dip coating, the coating thickness is 50 - 100 μm, and the sensitivity of the color reaction can be optimized by adjusting the dipping time and solution concentration.

[0060] The acidic gas detection layer 25 includes a thin film coated with methyl red indicator on its surface and a micro-port disposed on the thin film. The thickness of the thin film coated with methyl red indicator on its surface is 50 - 100 μm. When acidic gases, such as hydrogen ions or volatile acidic substances, contact the acidic gas detection layer 25, the pH of this layer decreases, and methyl red changes from yellow to red, and its color change range is a pH value of 4.4 - 6.2. The change in color transmits an electrical signal through the micro-port to the corresponding data processing module (acidic gas data processing module 265) in the signal data transmission and processing layer 26. The preparation of the thin film coated with methyl red indicator on its surface is prior art. In some embodiments of the present invention, the methyl red indicator is evenly coated on the substrate by spraying, the film layer thickness is 50 - 100 μm, and the spraying solution concentration is 0.1 wt%, ensuring that the film layer responds quickly when contacting acidic gases.

[0061] An ultra-thin inert isolation layer is provided between each odor detection film layer; the ultra-thin inert isolation layer is made of nano-scale alumina or silica. The thickness of the ultra-thin inert isolation layer is controlled to be 5 - 10 nm to prevent potential chemical reactions between adjacent film layers.

[0066] The acidic gas data processing module 265 includes a sensor for detecting acidic gases. In some embodiments of the present invention, it is the Hamamatsu S1326-02 sensor.

[0067] The micro-port 268 of the data processing layer is a micro-port that integrates multiple parallel lines, as shown in the appendix. Figure 6 As shown. Each odor detection film layer is connected to the micro-port 268 of the data processing layer through its respective micro-port, thereby realizing the connection between the odor detection film layer and the corresponding data processing module.

[0068] In some embodiments of the present invention, the Bluetooth module 266 and each data module are arranged at the rear part of the bilateral lingual side of the invisible orthodontic appliance.

[0069] The invisible orthodontic appliance body 1 and the oral odor detection film 2 are integrally compression molded. In some embodiments of the present invention, they are integrally compression molded by hot pressing and vacuum packaging.

[0070] In the present invention, the sensors for detecting each odor detection film layer are integrated into the signal data transmission and processing layer 26, which is responsible for simultaneously collecting the transmission and processing of signals from each gas detection film layer. The Bluetooth module 266 and the micro-circuit system 267 for supplying power to the Bluetooth module and each data processing module are also integrated in the data transmission and processing layer 26.

[0071] The micro-circuit system 267 is a thin-film battery, such as a thin-film lithium battery or a thin-film polymer battery. The thin-film battery is designed as an independent module in a thin and compact form (0.5 mm - 1 mm thick) and placed in the signal data transmission and processing layer 26 as a separate module, sharing the power interface with other modules to provide a stable power supply. The power of the thin-film battery is distributed to each module through an integrated circuit (such as a power management unit PMU) to ensure its normal operation. The thin-film battery is connected to each sensor through micro-wires to ensure efficient power transmission and modular design. The micro-circuit system 267 of the present invention is integrated with each data processing module on the same layer to reduce the volume and improve the system stability, while maintaining the comfortable wearing of the invisible orthodontic appliance.

[0113] Embodiment 6

[0114] This embodiment discloses an oral odor monitoring and correction device of the present invention, which includes the integrated oral odor monitoring invisible aligner of Embodiment 3, and further includes a smart device signal-connected to the integrated oral odor monitoring invisible aligner. The smart device includes a mobile phone, a computer, and a smart bracelet. The signal data transmission and processing layer 26 of the integrated oral odor monitoring invisible aligner transmits the monitoring results to the external smart device in a wireless Bluetooth manner, and on the smart device, specific application programs are used to perform real-time monitoring and visualization processing on the data.

[0115] When the present invention is used, the bracketless invisible aligner body 1 is worn on the dentition according to standard operations. Ensure comfort, and at the same time allow the inner side of the aligner to be in direct contact with the oral environment to obtain accurate gas samples.

[0116] An oral odor specific detection layer 2 is fixed at the lingual and palatal inner wall of the bracketless invisible aligner body 1. The composite film layer is closely attached to the area near the posterior teeth where oral gases are concentrated to ensure effective gas contact and stable signal collection. The design of the aligner body 1 closely fits the dentition to avoid signal errors caused by looseness.

[0117] After wearing, oral gases flow through multiple detection film layers, and each detection film responds to specific target gases, such as H 2 S, NH 3 , VOCs, etc., without the need for active operation by the patient or physician.

[0118] The detection layer material undergoes color change or conductivity change in response to specific gases. Each layer of sensor transmits the detected physical signals (color or conductivity) to the signal data transmission and processing layer 26.

[0119] The signal data transmission and processing layer 26 integrates the signals of each detection film layer and performs preliminary processing to ensure signal stability. The processed signals are wirelessly transmitted to an external intelligent device. The transmission frequency can be set as needed, for example, transmitted once every 15 minutes, or triggered by changes in the gas concentration threshold, saving energy consumption.

[0120] The application will automatically receive and decode the data transmitted by the appliance, generating easy-to-understand charts and trend graphs to help the patient or physician understand the changes in oral malodor.

[0121] When the concentration of a specific gas is detected to exceed the healthy threshold, the application will automatically pop up a warning prompt. It is also possible to view the historical records of the detection data to understand the changes in oral health over a period of time.

[0122] The application combines the detection data of each layer to conduct a specific analysis of the gas type. Based on the detected different gas types and concentrations, the application can warn of potential health problems. For example, high-concentration sulfides may indicate the risk of periodontal disease, high-concentration ketones may be related to metabolic abnormalities, and excessive acidic gases may reflect gastric acid reflux, etc. It evaluates oral and systemic health problems from multiple perspectives, improving the accuracy of diagnosis and treatment.

[0123] The above is only a preferred embodiment of the present invention, which is merely illustrative of the present invention and does not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present invention shall fall within the protection scope determined by the claims of the present invention.
