[0002] Functional silicone dental appliances are freely removable dental appliances. Since they do not need to be fixed on teeth, they are easy to clean, thus better maintaining oral hygiene and reducing the occurrence of dental caries.

[0052] The present application will now be further described based on preferred embodiments and with reference to the accompanying drawings.

[0053] Furthermore, for ease of understanding, various components on the drawings have been enlarged or reduced, but this is not intended to limit the scope of protection of this application.

[0054] Singular forms of words also include plural meanings, and vice versa.

[0056] The vocabulary used in this specification is for illustrative purposes and is not intended to limit the scope of this application. It should also be noted that, unless otherwise expressly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of these terms in this application.

[0057] Figure 1 and Figure 2A schematic diagram of the overall structure of an existing orthodontic appliance is shown. As shown in the figure, the orthodontic appliance 100 includes a U-shaped occlusal pad 102, the outer edges of the U-shaped occlusal pad 102 extending upward and downward to form a lip guard 101, the inner edges of the U-shaped occlusal pad 102 extending upward and downward to form a lingual guard 103, and the lip guard 101 having a plurality of air vents 104 in the middle. The U-shaped occlusal pad 102, the lip guard 101, and the lingual guard 103 together form an orthodontic appliance 100 that adapts to tooth occlusion.

[0058] As mentioned in the background, in order to monitor whether or not a dental appliance is being worn, this application provides a wearing monitoring device that can be used in conjunction with the aforementioned dental appliance 100. The applicant has discovered that when the dental appliance connected to the wearing monitoring device is moved from inside the mouth to outside the mouth, certain signals will change significantly. The wearing status of the dental appliance can be determined by analyzing the changes in these signals. Specifically, the signals that can change significantly can be at least sound signals, gas signals, temperature signals, or distance signals.

[0059] The principle will be explained below using sound signals as an example. Figure 14 As shown, when the orthodontic appliance is worn inside the mouth, the air exhaled from the nasal cavity collides with the monitoring device, causing vibrations and generating sound signals. When the orthodontic appliance is worn continuously inside the mouth, because the position of the monitoring device relative to the nasal cavity is relatively fixed, when the position between the signal acquisition module on the monitoring device and the nasal cavity meets certain conditions, the sound signal that can be acquired is a regular signal with a cycle of one breath, such as... Figure 15 The sound pressure-time curve shown is as follows: T1 represents one respiratory cycle when the orthodontic appliance is worn in the mouth, during which there is a sound pressure peak p1; when the orthodontic appliance is removed from the mouth, the distance between the monitoring device and the nasal cavity gradually increases, and the sound pressure peak in each respiratory cycle gradually decreases during this stage, as shown in p2; as the orthodontic appliance continues to move away from the nasal cavity, the monitoring module can no longer collect the sound signal generated by nasal exhalation, and the sound pressure peak in each respiratory cycle tends to stabilize again, as shown in p3; based on the above pattern, by setting a sound pressure threshold p, when the highest peak sound pressure in a respiratory cycle is less than the threshold p, it indicates that the orthodontic appliance has been removed from the mouth.

[0060] like Figure 16As shown, the changes in the above-mentioned sound signals can also be characterized by changes in the numerical value of sound frequency. When the orthodontic appliance is worn in the mouth, the frequency corresponding to the main peak in cycle T1 is f1. When the orthodontic appliance is removed from the mouth, due to the change in the relative position between the orthodontic appliance and the monitoring device, the frequency corresponding to the main peak in another respiratory cycle T2 becomes smaller, which is f2. Therefore, by setting a threshold f for sound frequency, when the frequency corresponding to the main peak in a respiratory cycle is less than the threshold f, it indicates that the orthodontic appliance has been removed from the mouth.

[0061] Similarly, the signal change can also be a change in the gas signal, specifically a change in carbon dioxide concentration or a change in gas pressure, wherein the changes in carbon dioxide concentration and gas pressure over time follow the same pattern as... Figure 15 The graph of sound pressure changing over time is similar and will not be described in detail here; similarly, by setting a threshold of carbon dioxide concentration as v or a threshold of gas pressure as P, when the peak value of carbon dioxide concentration or the peak value of gas pressure in a respiratory cycle is less than the set threshold, it indicates that the orthodontic appliance has been removed from the mouth.

[0062] In addition, the signal change can also be a change in temperature signal or distance signal. Figure 17 The diagram illustrates the change of temperature or distance signals over time when an orthodontic appliance is removed from inside the mouth and moved outside. Therefore, by setting a temperature threshold Q, if the temperature value measured at any time is less than the threshold, it indicates that the orthodontic appliance has been removed from the mouth. Similarly, by setting a distance threshold D, if the distance value measured at any time is greater than the threshold, it indicates that the orthodontic appliance has been removed from the mouth.

[0063] Clearly, the above signals can originate not only from the nasal cavity but also from the oral cavity.

[0064] In addition, in order to further amplify the changes in the signal when the orthodontic appliance is removed from inside the mouth to outside the mouth, this application also provides a signal enhancement structure, which will be described in conjunction with the following specific embodiments.

[0065] Example 1

[0066] Figure 3 — Figure 6 The diagrams shown are a connection diagram with the orthodontic appliance 100, an overall structural diagram, a top view, and a cross-sectional view. Figure 3 — Figure 6 As shown, this application provides a wearing monitoring device that can be used with the above-mentioned orthodontic appliance 100, which is detachably connected to the orthodontic appliance 100; in use, as... Figure 3 As shown, a monitoring device is attached to the orthodontic appliance 100 to monitor whether the orthodontic appliance 100 is being worn.

[0067] Specifically, the wearing monitoring device comprises a shell 1, a signal acquisition module 2, a control module and a power module (not shown in the figure), wherein the shell 1 is used to accommodate the signal acquisition module 2, the control module and the power module;

[0068] The signal acquisition module 2 is used to acquire signals that change significantly when the dental appliance 100 connected with the wearing monitoring device moves from the mouth to the outside of the mouth;

[0069] The control module is used to process and analyze the signals acquired by the signal acquisition module 2 to determine whether the dental appliance 100 is worn in the mouth, and the control module can also store the above data for subsequent retrieval and use of the above data as needed. It can be imagined that the control module can adopt any electronic device, system or equipment such as a microprocessor that can achieve the above functions of processing, analyzing and storing data;

[0070] The power module is electrically connected with the signal acquisition module 2 and the control module respectively, and is used to supply power to them.

[0071] Specifically, the shell 1 comprises a connecting part 11 and a containing part 13 arranged in sequence, the connecting part 11 is used to be detachably connected with the dental appliance 100, and the containing part 13 is used to accommodate the signal acquisition module 2, the control module and the power module, when the connecting part 11 is connected with the dental appliance 100, the containing part 13 is located outside the mouth;

[0072] Specifically, the connecting part 11 comprises two protruding parts which are connected with the air outlet hole 104 of the dental appliance 100; preferably, the protruding parts are cylindrical, and the diameter of the protruding parts is greater than the diameter of the air outlet hole 104 of the dental appliance 100 matched with the protruding parts, so that the protruding parts and the air outlet hole 104 form an interference fit;

[0073] Optionally, the connecting part 11 comprises more than two protruding parts which are connected with the air outlet hole 104 of the dental appliance 100 respectively, so as to further stabilize the connection.

[0074] Preferably, the shell 1 further comprises a guide plate part 12 located between the connecting part 11 and the containing part 13, when the protruding parts are connected with the air outlet hole 104, the end surface of the guide plate part 12 close to the protruding parts is in contact with the outer side surface of the lip stop 101 of the dental appliance 100; further, in order to improve the comfort of wearing, the two ends of the guide plate part 12 are arranged in a curved shape and the degree of curvature is matched with the lip stop 101 of the dental appliance 100; preferably, the thickness of the containing part 13 is less than the thickness of the guide plate part 12, so as to reduce the volume of the whole wearing monitoring device and further improve the comfort of use.

[0075] Furthermore, the signal acquisition module 2 is disposed on the upper end face of the accommodating portion 13 facing the nasal cavity, and is used to acquire signals originating from the nasal cavity. Preferably, in this embodiment, the horizontal distance between the signal acquisition module 2 and the oral cavity side end face that contacts the housing 1 and the orthodontic appliance 100, that is, the horizontal distance between the signal acquisition module 2 and the oral cavity side end face of the guide plate portion 12, is 0.5 to 5 cm. When the signal acquisition module 2 is in this position, the distance between the signal acquisition module 2 and the nasal cavity can meet the requirements for acquiring signals with significant changes.

[0076] Furthermore, the signal originating from the nasal cavity is the sound signal generated by the exhaled air from the nasal cavity, specifically manifested as sound frequency or sound pressure.

[0077] Furthermore, the signal acquisition module 2 is an acoustic sensor, which is used to acquire and transmit data to the control module for subsequent analysis and recording. The control module determines whether the orthodontic appliance 100 is worn in the mouth by the change in the peak frequency value or peak sound pressure value of the sound within a breathing cycle. Specifically, the threshold of sound frequency is 76-392Hz. When the frequency corresponding to the peak within a breathing cycle is less than this threshold, it indicates that the orthodontic appliance 100 has been moved from inside the mouth to outside the mouth.

[0078] Furthermore, the surface of the acoustic sensor can be covered with a waterproof and sound-permeable membrane. This membrane is used to prevent moisture or dust from entering the acoustic sensor, but at the same time, it allows the acoustic signal to propagate smoothly.

[0079] Alternatively, signals from the nasal cavity can also be gas signals such as carbon dioxide concentration and gas pressure, temperature signals, and distance signals.

[0080] Optionally, the signal acquisition module 2 may also be a carbon dioxide concentration sensor, a gas pressure sensor, a thermal infrared sensor, and an infrared ranging sensor.

[0081] Example 2

[0082] like Figure 7 The cross-sectional view of Embodiment 2 shown is different from Embodiment 1 above. Embodiment 2 also includes a signal enhancement structure 4, which is connected to the outside atmosphere. Specifically, it is a cavity structure disposed on the end face of the housing 1. When it is connected to the orthodontic appliance 100, the first port of the cavity that is connected to the outside atmosphere faces the nasal cavity to amplify the signal from the nasal cavity.

[0083] Specifically, when the collected signal is an acoustic signal, the cavity can repeatedly collide the gas from the nasal cavity with the inner side surface of the cavity, thereby enhancing the vibration of the gas, and thereby amplifying the signal. Compared with the above signal non-enhanced structure, the change of the signal caused by the position change of the dental appliance 100 is more obvious, so that the wearing condition of the dental appliance 100 can be more accurately judged.

[0084] Preferably, the cavity is an arc-shaped cavity, that is, the inner side surface of the cavity is an arc surface, which can further enhance the collision of the gas with the inner surface of the cavity; preferably, a plurality of protruding textures such as dots and strips are arranged on the inner side surface of the cavity to further enhance the vibration of the gas; preferably, the upper end surface of the cavity can be provided with a waterproof sound-permeable film to prevent external moisture or dust from entering the acoustic sensor.

[0085] Further, the signal collection module 2 is an acoustic sensor, which is located in the cavity and has a horizontal distance of 0.5-5 cm from the oral cavity side end surface in contact with the shell 1 and the dental appliance 100. When in this position, the distance between the signal collection module 2 and the nasal cavity can meet the collection of the obviously changed signal.

[0086] Alternatively, the collected signal can be a carbon dioxide concentration signal or a gas pressure signal, and the signal collection module 2 is a carbon dioxide concentration sensor or a gas pressure sensor. When the dental appliance 100 is correctly worn in the mouth, the amount of exhaled gas from the nasal cavity in the cavity of the signal enhancement structure 4 will change regularly with the breathing cycle, thereby causing the carbon dioxide concentration value or the gas pressure value measured by the sensor to also form a periodic change curve. When the dental appliance 100 is removed to the outside of the mouth, the amount of gas in the cavity tends to be stable, and the carbon dioxide concentration value or the gas pressure value in the cavity also tends to be stable.

[0087] Specifically, when the peak value of the carbon dioxide concentration in one breathing cycle is less than the set threshold value 5000 ppm, it indicates that the dental appliance 100 is removed from the mouth to the outside of the mouth.

[0088] Alternatively, the collected signal can also be a temperature signal or a distance signal.

[0089] Alternatively, the signal collection module 2 can also be a thermal infrared sensor or an infrared distance measuring sensor.

[0090] Embodiment three

[0091] Figure 8Fig. 4 shows a cross-sectional view of the signal enhancement structure 4 of Example 3, which is different from the signal enhancement structure 4 of Example 2 described above. The signal enhancement structure 4 of this example is a flow channel structure, which is arranged in the accommodating portion of the housing 1. When used in conjunction with the dental appliance 100, the first port of the signal enhancement structure 4, which is in communication with the atmosphere, faces the nasal cavity. The signal acquisition module 2 is arranged in the flow channel structure to acquire signals from the nasal cavity.

[0092] Specifically, the horizontal distance d1 between the signal acquisition module 2 and the end surface of the housing that is in contact with the dental appliance is 1-8 cm, and the vertical distance h1 between the signal acquisition module 2 and the first port is 0.5-6 cm.

[0093] Example 4

[0094] Figure 9 Fig. 5 shows a cross-sectional view of Example 4, which is different from Example 3 described above in that the signal enhancement structure 4 is a flow channel structure arranged on the oral side of the housing 1 to acquire signals from the oral side, i.e., when used in conjunction with the dental appliance 100, the first port of the flow channel structure, which is in communication with the atmosphere, faces the oral cavity.

[0095] Preferably, the first port is coaxially arranged with the air outlet hole 104 of the dental appliance 100 to better transmit signals from the oral cavity.

[0096] Further, the signal acquisition module 2 is arranged in the flow channel structure, and the horizontal distance between the signal acquisition module 2 and the first port is 0.5-8 cm, which can satisfy the acquisition of signals that change significantly.

[0097] Optionally, the signals from the oral cavity can be acoustic signals, gas signals, temperature signals, or distance signals.

[0098] Optionally, the signal acquisition module 2 can be an acoustic sensor, a carbon dioxide concentration sensor, a gas pressure sensor, a thermal infrared sensor, or an infrared distance sensor.

[0099] Example 5

[0100] Figure 10 and Figure 11 Fig. 6 shows a schematic view and a cross-sectional view of the overall structure of Example 5, which provides another form of signal enhancement structure 4. Based on Examples 2 and 3, a boss is arranged on the nasal side of the accommodating portion 13 of the housing 1, and the signal enhancement structure 4 is arranged in the boss. When used in conjunction with the dental appliance 100, the first port of the signal enhancement structure 4, which is in communication with the atmosphere, faces the nasal cavity. Through the design of the boss, the distance between the first port and the nasal cavity is further shortened, and the signals from the nasal cavity can be better received.

[0101] Specifically, the signal strengthening structure 4 can be a flow channel structure, a cavity structure, or a combination of the two, as long as a gas passage is formed in communication with the outside atmosphere;

[0102] Specifically, the signal collection module 2 is located in the signal strengthening structure 4, the horizontal distance d2 between the signal collection module 2 and the end surface of the shell 1 in contact with the dental appliance 100 is 0.5-7 cm, and the vertical distance h2 between the signal collection module 2 and the first port is 0.5-5 cm;

[0103] Optionally, the signal from the nasal cavity can be an acoustic signal, a gas signal, a temperature signal, or a distance signal.

[0104] Optionally, the signal collection module 2 can be an acoustic sensor, a carbon dioxide concentration sensor, a gas pressure sensor, a thermal infrared sensor, or an infrared distance sensor.

[0105] Embodiment six

[0106] Figure 12 and Figure 13 The overall structure schematic and cross-sectional view of embodiment six are shown respectively, and the difference between this embodiment and the above-mentioned embodiments one to five is that the shell 1 further comprises a signal receiving hole 15 on the end surface close to the oral cavity when connected with the dental appliance 100, one end of the signal receiving hole 15 is matched with the air outlet hole 104 on the dental appliance 100, and the other end is connected with the receiving end of the signal collection module 2 to collect the signal from the oral cavity.

[0107] Preferably, the signal collection module 2 is a thermal infrared sensor to collect temperature data, specifically the infrared heat generated by the oral cavity radiation and then converted into the corresponding temperature;

[0108] Further, the threshold value Q of the temperature signal is set to 34-40℃, and when the measured temperature value is less than the threshold value, it indicates that the dental appliance 100 is moved from the mouth to the outside.

[0109] Optionally, the signal collection module 2 can also be an infrared distance sensor, the signal emitted by the emitting end of the infrared distance sensor reaches the posterior palate of the oral cavity through the signal receiving hole 15 on the shell 1 and the air outlet hole 104 of the dental appliance 100 and is reflected to the receiving end of the infrared distance sensor, and the distance is calculated by the time difference data of signal generation and reception;

[0110] Further, the threshold value D of the distance signal is set to the standard distance+10mm, and the standard distance refers to the distance between the signal collection module 2 and the posterior palate of the oral cavity when the dental appliance 100 is correctly worn in the mouth; when the measured distance value is greater than the threshold value D, it indicates that the dental appliance 100 is moved from the mouth to the outside.

[0111] Optionally, the signal from the oral cavity can also be an acoustic signal or a gas signal.

[0112] Optionally, the signal collection module 2 can also be an acoustic sensor, a carbon dioxide concentration sensor or a gas pressure sensor.
