DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] In the description of the present application, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0032] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0034] In the existing orthodontic treatment, orthodontic wires are used to provide continuous correction force for misaligned teeth. Specifically, the restoring force of the orthodontic arch wire deforming to the target shape pushes the misaligned teeth to the target position. The restoring force is first transmitted to the orthodontic bracket, and then to the teeth. The teeth gradually shift to the target position under continuous force, and finally each tooth is squeezed to the corresponding position by the orthodontic wire and arranged neatly, achieving the purpose of orthodontic correction. Due to the obvious differences in different oral environments, the correction force provided by the orthodontic wire is too large or too small, which will have an adverse effect on the correction process. However, it is difficult to directly apply orthodontic wires in clinical practice to make them adapt well to the target oral environment, and doctors need to have sufficient experience. This subjective judgment of whether the correction force of the orthodontic wire is appropriate by the doctor is less reliable, because the correction force generated by the deformation of the orthodontic wire is difficult to accurately determine, and it is difficult to meet the development direction of precise orthodontics. Therefore, it is necessary to understand the performance of the orthodontic wire in a specific use environment through simulation. However, the current simulation device is difficult to efficiently and accurately simulate the use of the orthodontic wire in the target environment. Deformed dental models are used to simulate the application of orthodontic wires and related components in the oral environment, but the simulation effect is not good enough, and bracket particles may fall off, which will have an adverse effect on the results.

[0035] Therefore, the embodiment of the present application provides an orthodontic wire application simulation device 100, which has the characteristics of simple and stable structure and strong operability. Figure 1 A schematic diagram of an orthodontic wire application simulation device 100 in one embodiment of the present application; Figure 2 This is a schematic diagram of a first pressing plate 110 in an embodiment of the present application; Figure 3 FIG. 1 is a schematic diagram of the second pressing plate 120 in one embodiment of the present application. Figures 1 to 3 As shown, the orthodontic wire application simulation device 100 includes:

[0036] A first pressing plate 110, wherein a screw hole 111 is disposed on the first pressing plate 110, and the screw hole 111 passes through the first pressing plate 110;

[0037] A second pressing plate 120, wherein the second pressing plate 120 is provided with an avoidance hole 121, and the avoidance hole 121 can be communicated with the screw hole 111 when the first pressing plate 110 and the second pressing plate 120 overlap;

[0038] A locking structure, used to lock the first pressing plate 110 and the second pressing plate 120 in an overlapping state;

[0039] The ejector screw 130 cooperates with the screw hole 111 and is used to penetrate from one side of the first pressing plate 110 to the other side.

[0040] In the embodiment of the present application, the first pressing plate 110 and the second pressing plate 120 can be stably maintained in an overlapping state by a locking structure, and the orthodontic wire 200 is clamped therebetween. When the orthodontic wire 200 is between the first pressing plate 110 and the second pressing plate 120, the ejector screw 130 is screwed into the screw hole 111 from the side of the first pressing plate 110 away from the second pressing plate 120, and is ejected from the side of the first pressing plate 110 close to the second pressing plate 120, thereby supporting the orthodontic wire 200 and pushing the orthodontic wire 200 into the avoidance groove, causing bending and deformation. When using the orthodontic wire application simulation device 100 of the embodiment of the present application, the amount of downward pressure of the ejector screw 130 can be accurately controlled by screwing the ejector screw 130, thereby accurately controlling the deformation amount of the orthodontic wire 200. Therefore, it is possible to better simulate the elastic changes and stress-induced martensitic phase transformation of the orthodontic wire 200 under the state of abnormal tooth arrangement, and then analyze the fracture mechanics of the orthodontic wire 200 and the force attenuation of the orthodontic wire 200 in the oral environment.

[0041] like Figure 2As shown, in this embodiment, the first pressing plate 110 includes a plurality of spaced screw holes 111, and when the first pressing plate 110 and the second pressing plate 120 are in an overlapping state, at least one screw hole 111 is connected to the avoidance hole 121. It should be understood that the arrangement of the plurality of screw holes 111 allows for more options for the deformation test position of the orthodontic wire 200. When the second pressing plate 120 is replaced according to the situation, resulting in a change in the position of the avoidance hole 121, more screw holes 111 can ensure that there are screw holes 111 that can correspond to the avoidance hole 121.

[0042] In addition, more screw holes 111 can be provided to fix the orthodontic wire 200 clamped between the first pressing plate 110 and the second pressing plate 120 with screws, and the insertion position of the screws used for fixing should be staggered from the avoidance holes 121 .

[0043] As shown in the figure, a plurality of screw holes 111 are arranged at intervals along the U-shaped path. This arrangement is more consistent with the arrangement of teeth in the oral cavity during actual application, and can more accurately simulate clinical applications. It should be understood that in the embodiment of the present application, the U-shaped path can be roughly U-shaped, and in order to adapt to the shape of the orthodontic wire, the path can be partially bent and deformed to a certain extent.

[0044] It should be understood that the arrangement, density and number of the screw holes 111 should be selected according to actual needs and are not limited to the number and arrangement shown in the figure.

[0045] In this embodiment, the second pressing plate 120 includes a plurality of avoidance holes 121 arranged at intervals, and when the first pressing plate 110 and the second pressing plate 120 are in an overlapping state, each avoidance hole 121 is connected to at least one screw hole 111. Figure 3 As shown, four avoidance holes 121 are provided on the second pressing plate 120 , and the four avoidance holes 121 are spaced apart from each other. The avoidance holes 121 are used to reserve a certain space so that the orthodontic wire 200 can be deformed into the avoidance holes 121 .

[0046] Since the size of the avoidance hole 121 will have a certain influence on the deformation of the orthodontic wire 200, in an optional embodiment of the present application, the diameter of the avoidance hole 121 can be selected to be 3 mm to 20 mm. Optionally, the specific size of the avoidance hole 121 can be determined according to the distance between the two crowns in the simulated tooth shape, for example, the diameter of the avoidance hole 121 is the same as the distance between the center points of the two crowns in the simulated tooth shape.

[0047] Optionally, the avoidance hole 121 may be a blind hole, the opening of which faces the first pressing plate 110 ; the avoidance hole 121 may also be a through hole.

[0048] It should be understood that in other optional embodiments of the present application, the number of the avoidance holes 121 can be increased or decreased according to actual simulation conditions. The shape of the avoidance holes 121 is not limited to a circle, but can also be an ellipse, a bar, a rectangle or other shapes.

[0049] In an optional embodiment, a loading groove 123 for accommodating the orthodontic wire 200 is provided on the surface of the second pressing plate 120, and the extension path of the loading groove 123 is consistent with the arrangement path of the plurality of screw holes 111 and passes through the avoidance hole 121. Figure 3 As shown in the figure, the loading groove 123 also presents a U-shape, which is consistent with the arrangement path of the screw holes 111. When the first pressing plate 110 and the second pressing plate 120 are in an overlapping state, the projection of each screw hole 111 on the second pressing plate 120 falls within the loading groove 123 or the avoidance hole 121, so that the ejector screw 130 screwed into the screw hole 111 can always abut against the orthodontic wire 200 installed in the loading groove 123.

[0050] In this embodiment, the locking structure includes a fastener (not shown in the figure), a first mounting hole 112 located at the first pressure plate 110, and a second mounting hole 122 located at the second pressure plate 120. The fastener cooperates with the first mounting hole 112 and the second mounting hole 122 to lock the first pressure plate 110 and the second pressure plate 120 in an overlapping state.

[0051] Specifically, the first mounting hole 112 may be a through hole with a smooth inner wall, the inner wall of the second mounting hole 122 may have an inner screw hole 111, and the fastener may be a screw, which passes through the first mounting hole 112 and is threadedly matched with the second mounting hole 122, thereby completing the fastening of the first pressing plate 110 and the second pressing plate 120. It is understandable that the second mounting hole 122 may also be set as a through hole with a smooth inner wall, and the fastener may be a bolt or nut, which may also play a fixing role.

[0052] In this embodiment, the first pressing plate 110 and the second pressing plate 120 are both rectangular plates, the first mounting holes 112 are located at the four corners of the first pressing plate 110, and the second mounting holes 122 are located at the four corners of the second pressing plate 120. Of course, the distribution positions of the first mounting plate and the second mounting plate can also be adjusted, but a one-to-one correspondence should be ensured.

[0053] In other optional embodiments, the locking structure may also include a clamping structure (not shown in the figure) for clamping the first pressure plate 110 and the second pressure plate 120 or a snap structure (not shown in the figure) for connecting the first pressure plate 110 and the second pressure plate 120.

[0054] In an optional embodiment of the present application, the orthodontic wire application simulation device 100 may further include a water tank, in which the first pressing plate 110 and the second pressing plate 120 are disposed. The water tank may be used to hold physiological saline to further simulate the environment of the oral cavity.

[0055] Furthermore, the water tank may be provided with a heating component so that the physiological saline in the water tank is always maintained at a reasonable oral temperature, thereby achieving a more accurate simulation.

[0056] The method of using the orthodontic wire application simulation device 100 provided in this embodiment is:

[0057] First, the orthodontic wire 200 is placed in the loading groove 123 of the second pressing plate 120, and then the first pressing plate 110 is placed on the second pressing plate 120, and the first pressing plate 110 is tightly fixed on the second pressing plate 120 using a locking structure. Then, the ejector screw 130 is screwed into the screw hole 111 corresponding to the avoidance hole 121, and finally abuts against the orthodontic wire 200. Then, the deformation amount of the orthodontic wire 200 is controlled by the screw-in amount. When the orthodontic wire 200 is adjusted to a suitable deformation amount, the entire first pressing plate 110 and the second pressing plate 120 are placed in a water tank, and the water tank is filled with physiological saline, which is maintained at 37 degrees Celsius by a heating component to accurately simulate the environment of the oral cavity. After a certain test time, the orthodontic wire 200 can be taken out to analyze the elastic change and force attenuation of the orthodontic wire 200. Through the device provided in the embodiment of the present application, the deformation amount of the orthodontic wire 200 can be freely and conveniently adjusted, and the whole process is simple and stable, and the use conditions are not harsh.

[0058] In summary, the orthodontic wire application simulation device 100 provided in the embodiment of the present application includes a first pressing plate 110, a second pressing plate 120, a locking structure and an ejection screw 130. The first pressing plate 110 is provided with a screw hole 111, and the screw hole 111 passes through the first pressing plate 110. The second pressing plate 120 is provided with an avoidance hole 121, and the avoidance hole 121 can be connected with the screw hole 111 when the first pressing plate 110 and the second pressing plate 120 overlap. The locking structure is used to lock the first pressing plate 110 and the second pressing plate 120 in an overlapping state. The ejection screw 130 cooperates with the screw hole 111 to pass through from one side of the first pressing plate 110 to the other side. When the orthodontic wire 200 is simulated and tested, the orthodontic wire 200 is clamped by the first pressing plate 110 and the second pressing plate 120, and the orthodontic wire 200 passes through the avoidance hole 121, and then the ejector screw 130 passes through the screw hole 111 and is held against the orthodontic wire 200, and the deformation of the orthodontic wire 200 is controlled by the screwing depth of the ejector screw 130. Therefore, the orthodontic wire application simulation device 100 can conveniently simulate the deformation state of the orthodontic wire 200 in clinical application, and the structure is simple, stable, and easy to operate.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
