[0053] In recent years, the problem of malocclusion in children has become increasingly serious, and the demand for orthodontic treatment has gradually increased. Orthodontics is the process of straightening misaligned teeth by using braces to apply force to the teeth to be straightened, thereby achieving a straight alignment of teeth without damaging the health of the teeth and surrounding tissues.

[0058] like Figures 1 to 8As shown, this application provides a dental appliance, including: an appliance body 10, a power module 30, a sliding limiting structure 40, and a pulsed electromagnetic field module 50. The appliance body 10 is used to correct teeth in the oral cavity and includes a receiving groove 20 and a receiving drawer 21 detachably connected to the receiving groove 20. The power module 30 is housed in the receiving drawer 21 and is detachably attached to the appliance body 10 along with the receiving drawer 21. The power module 30 provides electrical energy. The sliding limiting structure 40 is disposed on the appliance body 10 in a horizontal or vertical direction and can be positioned opposite to an auxiliary position of the teeth being corrected. The pulsed electromagnetic field module 50 is disposed on the sliding limiting structure 40 and connected to the power module 30 to obtain the electrical energy provided by the power module 30. The pulsed electromagnetic field module 50 slides with the sliding limiting structure 40 to a target position opposite to the auxiliary position and generates magnetic induction intensity at the target position relative to the auxiliary position of the teeth being corrected. The specific structure and connection relationship of each device will be described below.

[0059] Specifically, in this embodiment, the orthodontic appliance body 10 includes a horizontal connecting support 14. The outer edges of the horizontal connecting support 14 extend upward and downward respectively to form the labial and buccal guard portions 11 of the orthodontic appliance body 10. The surface height of the labial and buccal guard portions 11 gradually decreases from the middle position of the horizontal connecting support 14 to the two end openings, making the labial and buccal guard portions 11 generally high in the middle and low at both ends, for adapting to oral wear and releasing the dental arch from the muscles of the lips and cheeks. The labial and buccal guard portions 11 include an integrally formed upper lip buccal guard portion and a lower lip buccal guard portion. The inner edges of the horizontal connecting support 14 extend upward and downward respectively to form the lingual guard portion 12 of the orthodontic appliance body 10. The upper surface of the lingual guard portion 12 is smooth, and the lower surface is a protruding arc shape, for adapting to lingual wear and correcting bad tongue thrusting habits. The lingual guard portion 12 includes an integrally formed upper lingual guard portion and a lower lingual guard portion. The upper lip buccal stop 11, the upper end face of the horizontal connecting support 14 and the upper lingual stop form the upper tooth guide groove 13 for wearing the maxillary teeth, and the lower lip buccal stop 11, the lower end face of the horizontal connecting support 14 and the lower lingual stop form the lower tooth guide groove (not shown) for wearing the mandibular teeth. The upper tooth guide groove 13 and the lower tooth guide groove are integrally formed to form the main body 10 of the orthodontic appliance.

[0060] In this embodiment, the orthodontic appliance body 10 further includes a receiving slot 20 and a receiving drawer 21 detachably connected to the receiving slot 20. The receiving slot 20 can be located at any position on the orthodontic appliance body 10; in this embodiment, it is preferably located at the tooth root position and inside the orthodontic appliance body 10. The number of receiving slots 20 can be specifically set according to requirements. The receiving slot 20 has a shape and structure adapted to the receiving drawer 21. For example, if the overall shape and structure of the receiving drawer 21 is cuboid, then the slot of the receiving slot 20 is also cuboid. A detachable drawer 21 is detachably connected to a receiving groove 20. The drawer 21 includes a receiving baffle 22, a receiving carrier 23, and a mounting groove 24. The receiving baffle 22 has a curved surface that adapts to the outer end face of the lip and cheek stop 11. When the drawer 21 is inserted into the receiving groove 20, the receiving baffle 22 is located on the outer end face of the lip and cheek stop 11 and is integrated with it. In one example, the receiving baffle 22 is located on the outer end face of the lip and cheek stop 11 and slightly protrudes from it, with a protrusion height of approximately 1 mm. The receiving carrier 23 is located on the side of the receiving baffle 22 facing the receiving groove 20 and is integrally formed with the receiving baffle 22. The receiving carrier 23 has a shape and structure adapted to the receiving groove 20 so as to be received in the receiving groove 20. The receiving carrier 23 and the receiving baffle 22 are inserted into and received in the receiving groove 20 by friction between the receiving carrier 23 and the groove wall of the receiving groove 20. The assembly groove 24 is provided on the receiving carrier 23 for assembling the battery 31 of the power module 30 (described below).

[0061] It should be noted that the main body 10 of the orthodontic appliance is generally made of silicone. To facilitate the secure mounting of the drawer 21 into the receiving slot 20 of the main body 10, the drawer 21 is also made of silicone. After the drawer 21 is inserted into the receiving slot 20, it is in close contact with the main body 10, ensuring that liquids in the mouth do not enter the receiving slot 20. To facilitate the removal of the drawer 21 from the receiving slot 20, a concealed hook (not shown) and a concealed groove (not shown) are provided on the outer wall of the receiving baffle 22 of the drawer 21. When not in use, the concealed hook is completely housed in the concealed groove, and in this state, the concealed hook and the concealed groove constitute part of the outer wall of the receiving baffle 22. When in use, the concealed hook can be lifted, thereby removing the drawer 21 from the receiving slot 20.

[0062] The power module 30 is housed in the receiving drawer 21 and is detachably attached to the orthodontic body 10 along with the receiving drawer 21. The power module 30 is used to provide electrical energy. Specifically, in this embodiment, the power module 30 includes: a storage battery 31, a power distribution structure 32, and a retractable cable 33. The storage battery 31 is detachably disposed in the receiving drawer 21, specifically in the mounting slot 24 of the receiving drawer 21, and is used to store and release electrical energy. The power distribution structure 32 is disposed on the receiving drawer 21 and connected to the storage battery 31, and is used to adjust and control the storage and discharge of the storage battery 31. Specifically, in this embodiment, the power distribution structure 32 is disposed on one side wall of the receiving carrier 23 and connected to the storage battery 31. One side of the receiving carrier 23 is the side that fits against the receiving baffle 22, and the receiving carrier 23 is disposed in close contact with the receiving baffle 22. The power distribution structure 32 includes a transformer transmission link (not shown), a control terminal (not shown), and a charging line (not shown). The transformer transmission link converts and outputs the current of the battery 31 to provide power to connected structures; the control terminal controls the charging and discharging of the battery 31; and the charging line connects to external structures to charge the battery 31. A retractable cable 33 is disposed in a cable tray 41 (described below). One end of the retractable cable is connected to the power distribution structure 32, and the other end is connected to a cable interface (described below) to transmit the power from the battery 31 to the pulse electromagnetic field module 50. The other end of the retractable cable 33 is plugged into the cable interface to allow connection when needed and disconnection when not needed. Further, in this embodiment, one end of the retractable cable 33 is connected to the transformer transmission link, and the other end is connected to the cable interface to transmit the power from the battery 31 to the pulse electromagnetic field module 50. The retractable ribbon cable 33 can be configured as a spring-shaped ribbon cable or a coiled spring-shaped ribbon cable. The spring-shaped ribbon cable can change its shape according to the applied force. That is, when an external force is applied to the retractable ribbon cable 33, the spring-shaped retractable ribbon cable 33 is stretched. When the external force is removed, the spring-shaped retractable ribbon cable 33 returns to its original position. Thus, without affecting the normal current transmission of the ribbon cable, the neatness of the space occupied by the ribbon cable and the rational use of the space can be maintained.

[0063] In this embodiment, the battery 31 can be charged by removing the receiving drawer 21 from the orthodontic body and then removing it from the receiving drawer 21. Alternatively, the battery 31 can be charged directly without removing the receiving drawer 21. Specifically, the power module 30 further includes a charging interface 34, which is located outside the receiving drawer 21 relative to the battery 31. One end of the charging interface 34 is connected to the power distribution structure 32, and the other end can be connected to an external power source for charging the battery 31. Furthermore, the charging interface 34 is located on the outer wall of the receiving baffle 22 of the receiving drawer 21 relative to the battery 31, and one end of the charging interface 34 is connected to the control terminal and the charging line, while the other end can be connected to an external power source. When the external power source is connected to the charging interface 34, the battery 31 can be charged through the external power source.

[0064] In this embodiment, considering that the orthodontic appliance is placed in the oral cavity, in order to prevent liquid in the oral cavity from flowing into the interior of the receiving drawer 21 through the charging interface 34 and coming into contact with the battery 31 to cause short circuits or other effects, the power module 30 is also provided with a protective patch 35. The protective patch 35 is located on the outside of the receiving drawer 21, specifically on the outer side wall of the receiving baffle 22 of the receiving drawer 21, and can encapsulate the charging interface 34 to prevent liquid in the oral cavity from flowing into the interior of the receiving drawer 21 through the charging interface 34, thereby improving the safety of using the orthodontic appliance.

[0065] In this embodiment, to facilitate the control of opening or closing the battery 31, the power module 30 also includes a switch button 36. The switch button 36 is located outside the accommodating drawer 21, specifically on the outer wall of the accommodating baffle 22 of the accommodating drawer 21, and on the side of the charging interface 34, for easy operation by the user. The switch button 36 is connected to the control terminal of the power distribution structure 32 and is used to control the opening or closing of the battery 31, thereby realizing the discharge of the battery 31. Since the energy of the battery 31 will gradually decrease with the length of use, an indicator light 37 is also provided to clearly know the amount of (remaining) energy of the battery 31. The indicator light 37 is located outside the accommodating drawer 21, specifically in the accommodating baffle 22 (which may be a transparent structure). The indicator light 37 is connected to the control terminal of the power distribution structure 32 and is used to flash when the battery 31 reaches the charging threshold. The indicator light 37 is mainly used to warn users of the remaining power of the battery 31, so that the user can charge the battery 31 in time and thus not affect the normal use of the orthodontic appliance. In addition, the indicator light 37 can also display the remaining power value and flash when fully charged.

[0066] It should be noted that, in order to reasonably control the magnetic induction intensity of the pulse electromagnetic field module 50, the power supply module 30 also includes a speed adjustment button 38. The speed adjustment button 38 is located on the outside of the receiving drawer 21, specifically on the outer wall of the receiving baffle 22 of the receiving drawer 21, and next to the indicator light 37, for convenient user operation. The speed adjustment button 38 is connected to the control terminal of the power distribution structure 32 and is used to control the magnitude of the discharge voltage of the battery 31, thereby enabling the pulse electromagnetic field module 50 to control the magnetic induction intensity of different levels. The magnetic induction intensity of each level is set based on experimental data, which can improve the speed of orthodontic treatment without affecting human health.

[0067] It should also be noted that, in this embodiment, the charging and discharging of the aforementioned battery 31, as well as the control of the indicator light 37 to flash, are implemented by a microprocessor (a conventional PLC (Programmable Logic Controller)). The microprocessor is located in the receiving baffle 22 of the receiving drawer 21 and is connected to the power distribution structure 32, the indicator light 37, and other structures. It is used to cooperate with the switch button 36 to control the charging of the battery 31; to cooperate with the transformer transmission connection and the power control terminal to control the discharging of the battery 31; and to cooperate with the battery 31 and the indicator light 37 to measure the charge of the battery 31 and control the indicator light 37 to flash when the battery 31 reaches the charging threshold.

[0068] In this embodiment, the retractable cable 33 of the power module 30 can be connected to the pulse electromagnetic field module 50 via the sliding limiting structure 40 to supply power to the pulse electromagnetic field module 50. The sliding limiting structure 40 also allows the pulse electromagnetic field module 50 to slide to a target position opposite to the auxiliary position of the orthodontic tooth, so that the pulse electromagnetic field module 50 generates magnetic induction intensity at the target position relative to the auxiliary position of the orthodontic tooth. The sliding limiting structure 40 is disposed on the orthodontic appliance body 10 in a horizontal or vertical direction and can be opposite to the auxiliary position of the orthodontic tooth. The auxiliary position of the orthodontic tooth refers to the location of the surrounding tissues of the orthodontic tooth. The specific structure of the sliding limiting structure 40 disposed on the orthodontic appliance body 10 will be described in detail below.

[0069] Among them, such as Figure 4 and Figure 5As shown, in one structural configuration, a sliding limiting structure 40 is horizontally disposed on the orthodontic body 10. Specifically, the sliding limiting structure 40 includes: a cable tray 41, a horizontal sliding groove 42, multiple edge retaining grooves 44, at least one lever 45, a lever 46, and a sealing strip 47. The cable tray 41 is horizontally recessed into the surface of the lip / cheek guard 11 and / or the tongue guard 12 of the orthodontic body 10. The cable tray 41 has a groove shape adapted to the curved surface of the lip / cheek guard 11 or the tongue guard 12 of the orthodontic body 10. This groove shape can be configured to be wide in the middle and gradually narrow towards both ends, or the groove shape can be configured to have a uniform width. The cable tray 41 is used to accommodate a retractable cable 33, allowing the retractable cable 33 to move and change state within the cable tray 41. In this embodiment, the wiring channel 41 is preferably located on the lip and cheek guard portion 11 of the orthodontic body 10. In this case, the opening of the wiring channel 41 is located on the outer surface of the lip and cheek guard portion 11. Similarly, when the wiring channel 41 is located on the tongue guard portion 10 of the orthodontic body 10, the opening of the wiring channel 41 is located on the outer surface of the tongue guard.

[0070] In this embodiment, the horizontal groove 42 is recessed horizontally into the vertical groove wall of the wiring groove 41 and is located in the horizontal connecting support 14 connecting the upper tooth guide groove 13 and the lower tooth guide groove of the orthodontic appliance body 10. The groove opening of the horizontal groove 42 is located in the vertical groove wall of the wiring groove 41. The vertical groove cross-section of the groove opening of the wiring groove 41 covers and is larger than the vertical groove cross-section of the groove opening of the horizontal groove 42. The groove width of the horizontal groove 42 is small, which can be set to 1 mm. The groove width of the horizontal groove 42 is smaller than the groove width of the wiring groove 41. In the vertical direction, the horizontal groove cross-section of the horizontal groove 42 has an arc shape that is adapted to the orthodontic appliance body. The horizontal cross-section of the horizontal groove 42 can cover the horizontal cross-section of the upper tooth guide groove 13 and the lower tooth guide groove. A plurality of edge slots 44 are recessed at intervals along the edge of the opening of the horizontal groove 42 in the vertical groove wall of the wiring groove 41, and each edge slot 44 is opposite to each tooth.

[0071] At least one paddle 45 is housed in a horizontal slide 42 and can move within the slide 42 to an auxiliary position opposite to the tooth. In this embodiment, the paddle 45 has a coil housing space inside, which is used to house the magnetic generating coil 51 (described below) of the pulse electromagnetic field module 50. The outer end of the paddle 45 is connected to the power module 30. Specifically, the outer end of the paddle 45 includes a ribbon cable interface (not shown). One end of a retractable ribbon cable 33 is connected to the power distribution structure 32, and the other end is connected to the ribbon cable interface to transmit the electrical energy of the battery 31 to the pulse electromagnetic field module 50 through the retractable ribbon cable 33 and the ribbon cable interface. The ribbon cable interface and the other end of the retractable ribbon cable 33 are designed to be pluggable. In this embodiment, the horizontal cross-sectional area of ​​the paddle 45 can cover the auxiliary position of at least one tooth, and the horizontal cross-section of the paddle 45 can also be of various other shapes, such as ellipse, semicircle, square, circle, irregular shape, etc. In one example, the paddle 45 can be made of silicone.

[0072] The lever 46 is integrally formed and connected to the outer end of the paddle 45, and is perpendicular to the paddle 45. It can engage with the edge groove 44 to limit the movement position of the paddle 45 in the horizontal slide groove 42. Specifically, the lever 46 includes an integrally formed engaging end 461 and a toggle end 462. The engaging end 461 has a shape structure adapted to the groove shape of the edge groove 44 so that the engaging end 461 can engage with the edge groove 44. The toggle end 462 is located in the cable tray 41. The toggle end 462 is used to disengage the lever 46 from the edge groove 44 and move the lever 46. Placing the toggle end 462 in the cable tray 41 facilitates user operation. When it is necessary to move the lever 45 to an auxiliary position relative to a tooth, the lever 46 can be moved by moving the lever 46's moving end 462 to disengage the lever 46's locking end 461 from one edge groove 44 and move it along the horizontal direction of the horizontal slide 42 to the auxiliary position relative to a tooth, which is opposite to the other edge groove 44. The lever 46's moving end 462 can then be moved again to engage the lever 46's locking end 461 with the other edge groove 44.

[0073] At least one pick 45 is provided to meet the needs of different teeth being corrected. For example, pick A 45 can be positioned in the horizontal groove 42 to correspond to the auxiliary position of tooth a being corrected; pick B 45 can be positioned in the horizontal groove 42 to correspond to the auxiliary position of tooth b being corrected.

[0074] The pick 45 has a shape and size corresponding to the auxiliary position of the tooth being corrected. The pick 45 can slide through the horizontal groove 42 to the target position corresponding to the auxiliary position of the tooth being corrected, so that the magnetic induction intensity generated by the magnetic generating coil 51 in the pick 45 can be targeted to the auxiliary position of the tooth being corrected. This not only increases the speed of orthodontic treatment, but also improves the accuracy of the teeth that need to be corrected, and also protects the surrounding tissues of other normal teeth, making the overall orthodontic treatment of the user's oral cavity more effective.

[0075] Similarly, in this embodiment, to maintain the sealing and aesthetics of the lip and cheek guard portion 11 of the orthodontic body 10, a sealing strip 47 is also provided. The sealing strip 47 is disposed in the opening of the wiring groove 41 and is used to seal the wiring groove 41. The sealing strip 47 has a shape adapted to the opening of the wiring groove 41, or can cover the shape of the wiring groove 41. When the sealing strip 47 is sealed in the opening of the wiring groove 41, the lip and cheek guard portion 11 of the orthodontic body 10 can form a complete and smooth curved surface, thereby improving both the sealing and aesthetics of the lip and cheek guard portion 11 of the orthodontic body 10. In addition, in this embodiment, the material of the sealing strip 47 can be the same as the material of the orthodontic body 10.

[0076] In another structural form, such as Figure 7 As shown, the sliding limiting structure 40 is horizontally disposed on the orthodontic body 10. Specifically, the sliding limiting structure 40 includes: a cable tray 41, a vertical sliding groove 43, multiple edge retaining grooves 44, at least one lever 45, a lever 46, and a sealing strip 47. The cable tray 41 is horizontally recessed into the surface of the lip / cheek stop 11 and / or the tongue stop 12 of the orthodontic body 10. The cable tray 41 has a groove shape adapted to the curved surface of the lip / cheek stop 11 or the tongue stop 12 of the orthodontic body 10. This groove shape can be wide in the middle and gradually narrows towards both ends, or the groove shape can be uniformly wide. The cable tray 41 is used to accommodate the retractable cable 33, allowing the retractable cable 33 to move and change state within the cable tray 41. In this embodiment, the wiring channel 41 is preferably located on the lip and cheek guard portion 11 of the orthodontic body 10. In this case, the opening of the wiring channel 41 is located on the outer surface of the lip and cheek guard portion 11. Similarly, when the wiring channel 41 is located on the tongue guard portion 10 of the orthodontic body 10, the opening of the wiring channel 41 is located on the outer surface of the tongue guard.

[0077] A vertical groove 43 is recessed vertically into the horizontal groove wall of the wiring groove 41 and is located inside the labial / buccal stop 11 and / or the lingual stop 12. The vertical groove 43 is perpendicular to the wiring groove 41. In this embodiment, the opening of the vertical groove 43 is located on the horizontal groove wall of the wiring groove 41. The groove width of the vertical groove 43 is relatively small, possibly 1 mm, and is smaller than the groove width of the wiring groove 41. The vertical cross-section of the vertical groove 43 can cover the vertical cross-sections of the upper tooth guide groove 13 and the lower tooth guide groove. Multiple edge-mounted slots 44 are recessed at intervals along the edges of the openings of the vertical groove 43 into the horizontal groove wall of the wiring groove 41, and each edge-mounted slot 44 is opposite to each tooth.

[0078] At least one paddle 45 is housed in a vertical slide 43 and can move within the slide 43 to an auxiliary position opposite to the tooth. The paddle 45 has an internal coil housing space for housing the magnetic generating coil 51 (described below) of the pulse electromagnetic field module 50. The outer end of the paddle 45 is connected to the power module 30. Specifically, the outer end of the paddle 45 includes a cable interface. One end of a retractable cable 33 is connected to the power distribution structure 32, and the other end is connected to the cable interface to transmit electrical energy from the battery 31 to the pulse electromagnetic field module 50 via the retractable cable 33 and the cable interface. The cable interface and the other end of the retractable cable 33 are designed for plug-in connection. In this embodiment, the vertical cross-sectional area of ​​the paddle 45 can cover the auxiliary position of at least one tooth, and the vertical cross-section of the paddle 45 can also be of various other shapes, such as ellipse, semicircle, square, circle, or irregular shape. In one example, the paddle 45 can be made of silicone.

[0079] The lever 46 is integrally formed and connected to the outer end of the paddle 45, and is perpendicular to the paddle 45. It can engage with the edge groove 44 to limit the movement position of the paddle 45 in the vertical slide groove 43. Specifically, the lever 46 includes an integrally formed engaging end 461 and a moving end 462. The engaging end 461 has a shape structure adapted to the groove shape of the edge groove 44 so that the engaging end 461 can engage with the edge groove 44. The moving end 462 is located in the cable tray 41. The moving end 462 is used to move the lever 46 out of the edge groove 44 and move the lever 46. Placing the moving end 462 in the cable tray 41 facilitates user operation. When it is necessary to move the lever 45 to an auxiliary position relative to a tooth, the lever 46 can be moved by moving the lever 46's moving end 462 to disengage the lever 46's locking end 461 from one edge groove 44 and move it along the horizontal direction of the horizontal slide 42 to the auxiliary position relative to a tooth, which is opposite to the other edge groove 44. The lever 46's moving end 462 can then be moved again to engage the lever 46's locking end 461 with the other edge groove 44.

[0080] At least one pick 45 is provided to meet the needs of different teeth being corrected. For example, pick A 45 can be positioned in the horizontal groove 42 to correspond to the auxiliary position of tooth a being corrected; pick B 45 can be positioned in the horizontal groove 42 to correspond to the auxiliary position of tooth b being corrected.

[0081] The pick 45 has a shape and size corresponding to the auxiliary position of the tooth being corrected, and the pick 45 can slide through the vertical slide 43 to the target position corresponding to the auxiliary position of the tooth being corrected. This allows the magnetic induction intensity generated by the magnetic generating coil 51 in the pick 45 to act specifically on the auxiliary position of the tooth being corrected. This not only increases the speed of orthodontic treatment but also improves the accuracy of the teeth being corrected, thereby protecting the surrounding tissues of other normal teeth and making the overall orthodontic treatment of the user's oral cavity more effective.

[0082] Furthermore, in one example, such as Figure 8 As shown, the wiring groove 41 is located at the upper or lower edge of the labial / buccal stop 11 and / or the lingual stop 12 of the orthodontic appliance body 10. A vertical groove 43 is recessed vertically into the horizontal groove wall of the wiring groove 41, and the groove shape of the vertical groove 43 is adapted to the curved surface of the labial / buccal stop 11 or the lingual stop 12. At this time, the vertical cross-section of the vertical groove 43 can cover the vertical cross-sections of the upper and lower tooth guide grooves. Correspondingly, the paddle 45 is entirely housed in the vertical groove 43, and during movement, the vertical cross-section of the paddle 45 can sequentially cover the vertical cross-sections of the upper and lower tooth guide grooves. Correspondingly, the lever 46 includes an integrally formed snap-fit ​​end 461 and actuating end 462. The snap-fit ​​end 461 has a shape structure adapted to the groove of the edge slot 44, so that the snap-fit ​​end 461 can snap into the edge slot 44. The actuating end 462 is located in the cable tray 41 and is used to actuate the lever 46 out of the edge slot 44 and move the lever 46.

[0083] In another example, the wiring channel 41 is located in the middle of the lip and cheek guard 11 and / or the tongue guard 12 of the orthodontic body 10. Figure 7As shown), the wiring groove 41 divides the labial / buccal stop 11 and the lingual stop 12 of the orthodontic appliance body 10 into upper and lower parts. Vertical grooves 43 are recessed vertically into the two opposing horizontal groove walls of the wiring groove 41, including an upper vertical groove and a lower vertical groove. At this time, the groove shape of the upper vertical groove matches the curved surface of the upper half of the labial / buccal stop 11 or the upper half of the lingual stop 12, and the vertical cross-section of the upper vertical groove can cover the vertical cross-section of the upper tooth guide groove 13; the groove shape of the lower vertical groove matches the curved surface of the lower half of the labial / buccal stop 11 or the lower half of the lingual stop 12, and the vertical cross-section of the lower vertical groove can cover the vertical cross-section of the lower tooth guide groove. Correspondingly, the edge slot 44 includes an upper edge slot and a lower edge slot. The upper edge slot is recessed along the edge of the opening of the upper vertical slide groove in the upper horizontal groove wall of the cable tray 41, and each upper edge slot is opposite to each upper tooth. The lower edge slot is recessed along the edge of the opening of the lower vertical slide groove in the lower horizontal groove wall of the cable tray 41, and each lower edge slot is opposite to each lower tooth.

[0084] Correspondingly, the paddle 45 includes an upper paddle and a lower paddle. The upper paddle is entirely housed in an upper vertical groove. During movement, the vertical cross-section of the upper paddle sequentially covers the vertical cross-section of the upper tooth guide groove 13. The lower paddle is entirely housed in a lower vertical groove. During movement, the vertical cross-section of the lower paddle sequentially covers the vertical cross-section of the lower tooth guide groove. Correspondingly, the lever 46 includes an upper lever 46 and a lower lever 46. The upper lever 46 is integrally formed and connected to the outer end of the upper paddle, and is perpendicular to the upper paddle. It can engage with the upper edge slot to limit the movement position of the upper paddle in the upper vertical groove. The lower lever 46 is integrally formed and connected to the outer end of the lower paddle, and is perpendicular to the lower paddle. It can engage with the lower edge slot to limit the movement position of the lower paddle in the lower vertical groove. Furthermore, the upper lever 46 includes an integrally formed upper locking end and an upper actuating end 462. The upper locking end has a shape structure adapted to the groove shape of the upper edge slot, so that the upper locking end can be locked into the upper edge slot. The upper actuating end 462 is located in the cable tray 41, and the upper actuating end 462 is used to actuate the upper lever 46 out of the upper edge slot and move the upper lever 46. The lower lever 46 includes an integrally formed lower locking end and a lower actuating end 462. The lower locking end has a shape structure adapted to the groove shape of the lower edge slot, so that the lower locking end can be locked into the lower edge slot. The lower actuating end 462 is located in the cable tray 41, and the lower actuating end 462 is used to actuate the lower lever 46 out of the lower edge slot and move the lower lever 46.

[0085] The horizontal slide 42, multiple edge slots 44, paddle 45, and lever 46 are further refined, making the auxiliary position of paddle 45 relative to the teeth being corrected more precise. Paddle 45 has a shape and size corresponding to the auxiliary position of the teeth being corrected, and paddle 45 can slide through the vertical slide 43 to the target position corresponding to the auxiliary position of the teeth being corrected. This allows the magnetic induction intensity generated by the magnetic generating coil 51 in paddle 45 to act specifically on the auxiliary position of the teeth being corrected, thereby improving the speed of orthodontic treatment and the accuracy of correcting the teeth that need orthodontic treatment. It also protects the surrounding tissues of other normal teeth, making the overall orthodontic treatment of the user's oral cavity more effective.

[0086] Similarly, in this embodiment, to maintain the sealing and aesthetics of the lip and cheek guard portion 11 of the orthodontic body 10, a sealing strip 47 is also provided. The sealing strip 47 is disposed in the opening of the wiring groove 41 and is used to seal the wiring groove 41. The sealing strip 47 has a shape adapted to the opening of the wiring groove 41, or can cover the shape of the wiring groove 41. When the sealing strip 47 is sealed in the opening of the wiring groove 41, the lip and cheek guard portion 11 of the orthodontic body 10 can form a complete and smooth curved surface, thereby improving both the sealing and aesthetics of the lip and cheek guard portion 11 of the orthodontic body 10. In addition, in this embodiment, the material of the sealing strip 47 can be the same as the material of the orthodontic body 10.

[0087] After the sliding limiting structure 40 is set in the main body 10 of the orthodontic appliance, the pulse electromagnetic field module 50 can be placed on the sliding limiting structure 40 and connected to the power module 30 to obtain the power supplied by the power module 30. The pulse electromagnetic field module 50 slides with the sliding limiting structure 40 to a target position relative to the auxiliary position, and generates magnetic induction intensity at the auxiliary position of the orthodontic tooth at the target position. Specifically, in this embodiment, the pulse electromagnetic field module 50 includes a magnetic generating coil 51, which is disposed in a coil accommodating space inside the lever 45 and is connected to a ribbon cable interface. The magnetic generating coil 51 slides with the lever 45 to a target position relative to the auxiliary position, and generates magnetic induction intensity at the auxiliary position of the orthodontic tooth at the target position.

[0088] In this embodiment, other auxiliary structures acting on the teeth being corrected can also be provided in the paddle 45. These structures include heating structures, cooling structures, light-emitting structures, and vibration structures. The heating structure includes a heating tube, the cooling structure includes a condenser tube, the light-emitting structure includes a lamp, and the vibration structure includes an electric motor. These structures can work in conjunction with the pulsed electromagnetic field module 50 to act on the tissues surrounding the teeth being corrected. Of course, these structures can also be used independently to act on the tissues surrounding the teeth being corrected.
