[0002] Bite force refers to the chewing pressure generated by the contraction of the masticatory muscles when the upper and lower teeth come into contact. The maintenance of the normal organizational structure and function of the periodontal tissue depends on the action of normal bite force.

[0038] Embodiment 1

[0039] Refer to Figures 1-4 As shown, this embodiment provides a biting force monitoring system, including:

[0040] A monitoring body 1, the monitoring body 1 has a cavity 12 for accommodating multiple teeth of the first dental arch, and the geometric shape of the cavity 12 is basically consistent with the geometric shape of the first dental arch, so that when the first dental arch is accommodated in the cavity 12, the position between the first dental arch and the monitoring body is stable; the opposing dental arch of the first dental arch is the second dental arch. During occlusion, the surface of the monitoring body 1 facing the second dental arch is the first surface 10, and the surface of the second dental arch facing the monitoring body 1 is the second surface. The geometric shape of the first surface 10 is consistent with the geometric shape of the second surface, so that the first surface 10 and the second surface are basically in contact during occlusion; specifically, the second surface is the surface of the second dental arch facing the opposing dental arch (i.e., the occlusal surface of the second dental arch), and the first surface 10 and the occlusal surface of the second dental arch are in concave-convex fit, so that the first surface 10 and the second surface are basically in contact during occlusion; wherein, the monitoring body 1 is a housing adapted to the shape of the first dental arch;

[0041] Bite force acquisition module 2. The inner surface of the cavity 12 facing the occlusal surface of the first dental arch is the third surface 11. A plurality of bite force acquisition modules 2 are arranged in sequence along the direction of the dental arch of the first dental arch on both the third surface 11 and the first surface 10. The plurality of bite force acquisition modules 2 on the third surface 11 correspond one-to-one in position to the plurality of bite force acquisition modules 2 on the first surface 10. The plurality of bite force acquisition modules on the third surface 11 correspond one-to-one to multiple teeth in the first dental arch;

[0042] Data processing module 7. The bite force acquisition module 2 is electrically connected to the data processing module 7.

[0043] Bite force is generated by the occlusion between the upper and lower teeth. When the bite force acquisition module in this embodiment is specifically used, the user's teeth are accommodated in the cavity 12 on the monitoring body 1, so that the monitoring body 1 is firmly worn on the user's first dental arch. The bite force acquisition modules 2 respectively installed on the first surface 10 and the third surface 11 are located between the cusp and the fossa, and can fully, comprehensively and accurately acquire the bite force, realizing three-dimensional monitoring of the user's bite force and comprehensively acquiring the bite force information of the entire dental arch.

[0044] Among them, the bite force acquisition module 2 includes a plurality of force measurement points. The plurality of force measurement points in each bite force acquisition module correspond to the cusp-fossa 60 positions of the teeth 6 on the first dental arch corresponding to its position. The cusp-fossa of each tooth is the area where stress is concentrated, which is of great significance for the measurement of bite force. Setting the bite force acquisition module 2 corresponding to the cusp-fossa position of the tooth can further more fully, comprehensively and accurately acquire the bite force of the entire dental arch.

[0045] Specifically, the bite force acquisition module 2 is a force sensor; among them, the bite force acquisition module 2 in this embodiment can be a thin film pressure sensor; a groove for installing the bite force acquisition module 2 is provided on the inner surface of the cavity 12, and the bite force acquisition module 2 is installed in the groove, and its surface forms a cavity 12 that coincides with the geometric shape of the first dental arch with the remaining inner surface of the cavity 12

[0046] Specifically, a silk fibroin film 5 is covered outside each bite force acquisition module 2. The silk fibroin film 5 is used as a protective layer to protect the bite force acquisition module 2. The silk fibroin film 5 has the functions of antibacterial sealing and can further stabilize the bite force acquisition module 2.

[0047] Specifically, the data processing module 7 includes a signal processing circuit, a central processor, a memory and a display;

[0048] The bite force acquisition module 2 is connected to the input end of the signal transmission belt 4 through the connection line 3. The output end of the signal transmission belt 4 is connected to the input end of the signal processing circuit. The output end of the signal processing circuit is connected to the ADC port of the central processor. The input ends of the display and the memory are both connected to the output end of the central processor. The signal of the bite force acquisition module 2 is transmitted through the signal transmission belt 4. The signal transmission belt 4 includes a plurality of signal channel lines 41 to achieve multi-channel signal transmission and can accelerate the signal transmission speed. Among them, the connection line 3 includes multiple groups of sub-connection lines 3. Each group of sub-connection lines 3 is connected to one bite force acquisition module 2. The connection line 3 can also be connected in series between multiple bite force acquisition modules 2.

[0049] The monitoring body 1 in this embodiment can be prepared by an integral molding process. For example, it can be prepared by vacuum thermoforming or 3D printing technology. After obtaining the digital models of the user's first dentition and second dentition, producing the monitoring body 1 in this embodiment through 3D printing technology can make the shape of the cavity 12 match the shape of the first dentition, which can not only ensure the sufficiency, comprehensiveness, and accuracy of obtaining bite force data, but also improve the wearing comfort of the user. The matching part of the cavity 12 in the monitoring body 1 in this embodiment with the cusp and fossa of the teeth accommodated therein is a protrusion 1313. The bite force acquisition module 2 on the first surface 10 corresponds to the position of the protrusion 1313. It should be noted that the bite force acquisition module 2 on the first surface 10 corresponding to the position of the protrusion 1313 is not limited to a single point on the first surface 10 and the third surface 11, but can also be the area around the protrusion 1313 on the first surface 10 and the third surface 11.

[0050] In a possible embodiment, the number of force measurement points in the bite force acquisition modules 2 near both ends of the monitoring body 1 is more than that in the bite force acquisition modules 2 in the middle of the monitoring body 1.

[0051] In a possible embodiment, the number of force measurement points in the bite force acquisition module on the third surface 11 is equal to the number of force measurement points in the bite force acquisition module provided on the first surface 10 corresponding to its position.

[0052] In a possible embodiment, the distance between the cusp and fossa of two adjacent teeth in the first dentition is d, and the numbers of force measurement points in the bite force acquisition module 2 corresponding to the positions of these two teeth are N1 and N2 respectively, where both N1 and N2 are inversely proportional to d; among them, in the specific implementation process, when the distance between two adjacent teeth, such as the lateral incisor and the canine, is very close in individual users, the number of force measurement points in the bite force acquisition module 2 corresponding to the positions of the lateral incisor and the canine can be set to be less than the number of force measurement points in the remaining bite force acquisition modules 2. This is because the distance between the cusp and fossa of the lateral incisor and the cusp and fossa of the canine is relatively small. Reducing the number of force measurement points can not only fully, comprehensively and accurately collect the bite force of the entire dentition, but also save costs. As shown in the appendix Figure 3 As shown, the cavity 12 includes a second cavity 122 for accommodating the lateral incisor and the canine, and also includes a first cavity 121 for accommodating the remaining teeth.

[0053] Embodiment 2

[0054] The difference between the bite force monitoring system in this embodiment and the bite force monitoring system in Embodiment 1 is that the housing in this embodiment includes an outer housing and an inner housing disposed inside the outer housing. The inner housing has a cavity 12, and the inner surface of the outer housing has a wire groove, and the connecting wire 3 is accommodated in the wire groove;

[0055] The outer housing and the inner housing are detachably and hermetically connected to prevent the connecting wire 3 from being eroded by water vapor.

[0056] Among them, a part of the inner surface of the outer housing protrudes outward to form a wire groove for accommodating the connecting wire 3. A retaining structure for preventing relative movement between the outer housing and the inner housing is provided between the remaining inner surfaces of the outer housing and the outer surface of the inner housing. Relative movement between the outer housing and the inner housing will affect the accuracy of bite force monitoring.

[0057] In a possible embodiment, the retaining structure is a frosted structure, and the frosted structure includes a first frosted layer provided on the outer surface of the inner housing and a second frosted layer provided on the inner surface of the outer housing and in close contact with the first frosted layer.
