Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to an orthodontic appliance. Background Technology
[0002] With the improvement of people's living standards, the demand for obtaining and maintaining correct occlusion, improving facial aesthetics, and enhancing oral hygiene is becoming increasingly strong. Consequently, the development of orthodontic appliances for correcting teeth is also improving, but competition is also becoming increasingly fierce.
[0003] In related technologies, orthodontic appliances include brackets and cover components that are detachably connected to the brackets. In some orthodontic cases, traction devices need to be fixed to the brackets to facilitate the use of traction materials (such as ligatures) to move the teeth. However, traditional traction devices, when fixed to the brackets, can easily create a foreign body sensation, which is detrimental to improving user experience and wearing comfort. Utility Model Content
[0004] This application provides an orthodontic appliance. When using this appliance, the user is less likely to experience a foreign body sensation, which improves the user experience and wearing comfort.
[0005] The technical solution is as follows:
[0006] According to a first aspect of the embodiments of this application, an orthodontic appliance is also provided, including a bracket, a cover, and a traction member. The bracket includes a carrier, a limiting body, and a mating body. The limiting body and the mating body are fixedly spaced and fixed to the carrier along a first direction to form an archwire groove. The limiting body includes a first surface disposed on a side of the limiting body away from the mating body. The cover is slidably connected to the mating body and is movable relative to the limiting body along the first direction, such that the cover has a closed state (closing the archwire groove) and an open state (opening the archwire groove). The traction member includes a connecting body and a traction body fixedly connected to the connecting body. The connecting body is detachably connected to the bracket, such that at least a portion of the traction body protrudes from the limiting body in a direction away from the mating body. The traction body includes a second surface, at least a portion of which smoothly engages with the first surface.
[0007] The technical solutions provided by the embodiments of this application have at least the following beneficial effects:
[0008] When using this orthodontic appliance, the brackets are fixed to the teeth via the support body, while the cover body slides through the fitting body. Moving the cover body opens the archwire slot. The archwire is then placed in the slot, and moving the cover body again conceals the archwire slot, confining it within the slot. During orthodontic treatment, when traction devices (such as ligatures) are needed to move the teeth, the connector is used to fix the traction device to the brackets. The traction body then engages with the traction device (such as ligatures) for binding, facilitating tooth movement and improving orthodontic efficiency.
[0009] When users wear orthodontic appliances with traction components, the smooth connection between the second and first surfaces ensures a seamless transition between the traction body and the limiting body, reducing the likelihood of a foreign body sensation and improving user experience and comfort. Furthermore, after the traction device (such as ligature wire) is applied and the alignment is completed, the connector and bracket can be removed, separating the traction component from the bracket, further reducing the foreign body sensation and enhancing user experience and comfort.

[0066] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this application. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this application.
[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.
[0068] To better understand the orthodontic appliance of this application, the following description is provided in conjunction with the accompanying drawings.
[0069] like Figures 1 to 8 As shown, in some embodiments, this application provides a bracket 100, a cover 200, and a traction member 300. The bracket 100 includes a carrier 110, a limiting body 120, and a mating body 130. The limiting body 120 and the mating body 130 are fixedly disposed on the carrier 110 at a distance along a first direction to form an archwire groove 140. The limiting body 120 includes a first surface 121, which is disposed on the side of the limiting body 120 away from the mating body 130. The cover 200 is slidably connected to the mating body 130 and is movable relative to the limiting body 120 along the first direction, so that the cover 200 has a closed state with the archwire groove 140 closed and an open state with the archwire groove 140 open. The traction member 300 includes a connecting body 310 and a traction body 320 fixedly connected to the connecting body 310. The connector 310 is detachably connected to the bracket 100, such that at least a portion of the traction body 320 protrudes from the limiting body 120 in a direction away from the mating body 130. The traction body 320 includes a second surface 321, at least a portion of which is smoothly engaged with the first surface 121.
[0070] When the orthodontic appliance 10 is in use, the bracket 100 is fixed to the teeth via the carrier 110, while the cover 200 is slidably connected to the mating body 130. The archwire slot 140 is opened by moving the cover 200. Then, the archwire 20 is placed in the archwire slot 140, and the cover 200 is moved again to cover the archwire slot 140, thus confining the archwire 20 within the slot. When it is necessary to use a traction device (such as a ligature wire) to move the teeth during orthodontic treatment, the traction device 300 is fixed to the bracket 100 via the connector 310. Then, the traction body 320 is used to bind and cooperate with the traction device (such as a ligature wire), which facilitates the use of the traction device (such as a ligature wire) to move the teeth, thereby improving the orthodontic efficiency.
[0071] When a user wears the orthodontic appliance 10 with the traction element 300, the smooth connection between the second surface 321 and the first surface 121 ensures a smooth connection between the traction body 320 and the limiting body 120. This reduces the likelihood of a foreign body sensation during wear, improving user experience and comfort. Furthermore, after the traction device (such as ligature wire) is secured and corrected, the connector 310 and the bracket 100 can be removed, separating the traction element 300 from the bracket 100. This further reduces the foreign body sensation and enhances user experience and comfort.
[0072] It should be noted that "the cover 200 is slidably connected to the mating body 130 and can move relative to the limiting body 120 along the first direction", that is, the sliding direction of the cover 200 is set in the same direction as the first direction.
[0073] In some embodiments, the first direction is arranged to intersect with the thickness direction of the support body 110. In this way, the limiting body 120 and the mating body 130 protrude from the support body 110 in the same direction along the thickness direction of the support body 110, and after the cover 200 and the mating body 130 are slidably connected, they will not interfere with the support body 110.
[0074] It should be noted that "the first direction intersects with the thickness direction of the carrier 110" includes intersecting at an acute angle, intersecting at an obtuse angle, and intersecting at a right angle (that is, the first direction is perpendicular to the thickness direction of the carrier 110).
[0075] Combined with appendix Figure 2 As shown, the first direction is the X-axis direction. Optionally, the first direction is the length direction of the base. The thickness direction of the support 110 is the Z-axis direction.
[0076] Optionally, such as Figure 2As shown, in some embodiments, the first surface 121 includes at least the upper surface of the limiting body 120, and the second surface 321 includes at least the upper surface of the traction body 320. Thus, the orthodontic appliance 10 is fixed to the user's teeth (or dental mold) by the carrier 110, and the upper surfaces of the limiting body 120 and the traction body 320 are most likely to come into contact with the user's tongue and / or lips. At this time, the upper surface of the limiting body 120 and the upper surface of the traction body 320 smoothly connect, making the connection between the traction member 300 and the limiting body 120 smooth, effectively reducing the foreign body sensation experienced by the user during the wearing of the orthodontic appliance 10, improving the user experience and wearing comfort.
[0077] like Figure 2 as well as Figure 6 or Figure 13 or Figure 20 As shown, in some embodiments, the second surface 321 is spaced apart from the support body 110 along the thickness direction of the support body 110, and the highest point of the traction body 320 is not higher than the highest point of the bracket 100. Thus, the spaced-apart arrangement of the second surface 321 from the support body 110 facilitates the use of the traction body 320 to fix traction objects (such as ligatures). Furthermore, the fact that the highest point of the traction body 320 is not higher than the highest point of the bracket 100 effectively reduces the patient's foreign body sensation, improving user experience and wearing comfort.
[0078] like Figures 3 to 7 As shown, in some embodiments, at least one of the first surface 121 and the second surface 321 has a convex arc surface, which is located at the junction of the two. This convex arc surface makes the junction of the first surface 121 and the second surface 321 smoother and less uncomfortable to the touch. When the user's tongue and / or lips come into contact with the convex arc surface, it is less likely to cause a foreign body sensation, thereby reducing the patient's foreign body sensation and improving the user experience and wearing comfort. It also makes the orthodontic appliance 10 more rounded and smooth, without obvious sharp edges.
[0079] Optionally, such as Figure 1 as well as Figure 5 As shown, in some embodiments, the outer surface and edges of the bracket 100 are rounded (e.g., rounded corners, deburred, or polished). This makes the orthodontic appliance 10 more rounded and smooth, without obvious sharp edges.
[0080] Optionally, such as Figure 1 as well as Figure 5 As shown, in some embodiments, the outer surface and edges of the cover 200 are rounded (e.g., rounded corners, deburred, or polished). This makes the orthodontic appliance 10 more rounded and smooth, without obvious sharp edges.
[0081] Optionally, such as Figure 3As shown, in some embodiments, the outer surface and edges of the traction member 300 are rounded (e.g., rounded corners, deburred, or polished). This makes the orthodontic appliance 10 more rounded and smooth, without obvious sharp edges.
[0082] It should be noted that the phrase "at least a portion of the second surface 321 smoothly connects with the first surface 121" should be interpreted broadly, meaning that the junction between the first surface 121 and the second surface 321 should not feel rough to the touch. It should not cause a foreign body sensation when in contact with the tongue and / or lips. Specifically, this includes at least a portion of the second surface 321 smoothly connecting with the first surface 121, at least a portion of the second surface 321 smoothly connecting with the first surface 121, and at least a portion of the second surface 321 having an arc-shaped transition with the first surface 121.
[0083] like Figures 1 to 6 As shown, in some embodiments, the first surface 121 and the second surface 321 are smoothly connected. In this way, the connection between the first surface 121 and the second surface 321 can disperse the stress generated during the biting process, thereby minimizing the patient's foreign body sensation, improving the user experience and wearing comfort, and also reducing the risk of the traction component 300 falling off.
[0084] It should be noted that "smooth transition" should be interpreted broadly to include various surface transition methods, such as cylindrical arc surfaces, elliptical cylindrical arc surfaces, ellipsoidal arcs, and spherical arcs. Specifically, smooth transition includes arc transitions, internal tangent transitions, external tangent transitions, and so on.
[0085] like Figures 2 to 6 As shown, in some embodiments, the first surface 121 includes a first curved surface 1211, and the second surface 321 includes a second curved surface 3211. The second curved surface 3211 smoothly connects with the first curved surface 1211. Thus, by utilizing the smooth connection between the first curved surface 1211 and the second curved surface 3211, the orthodontic appliance 10 becomes more rounded and smooth, without obvious sharp edges. Furthermore, the cooperation between the first curved surface 1211 and the second curved surface 3211 can disperse the stress generated during food biting, thereby reducing the patient's foreign body sensation, improving user experience and wearing comfort, and enhancing the fixation reliability of the traction component 300.
[0086] It should be noted that the first curved surface 1211 should be interpreted broadly to include non-planar surfaces that are not rough to the touch. Specifically, the first curved surface 1211 includes at least one of curved surfaces, spherical surfaces, etc.
[0087] It should be noted that the second surface 3211 should be interpreted broadly to include non-planar surfaces that are not rough to the touch. Specifically, the first surface 1211 includes at least one of curved surfaces, spherical surfaces, etc.
[0088] It should be noted that curved surfaces include cylindrical curved surfaces, elliptical curved surfaces, etc. Spherical surfaces include spherical surfaces, ellipsoidal surfaces, etc.
[0089] In some embodiments, the first curved surface 1211 is tangent to the second curved surface 3211, so that the first surface 121 and the second surface 321 transition smoothly. In this way, it is easy to achieve a smooth connection between the first curved surface 1211 and the second curved surface 3211, which helps to reduce the design difficulty of the orthodontic appliance 10.
[0090] It should be noted that "the first surface 1211 is tangent to the second surface 3211" should be interpreted broadly, including tangency in the extension direction of the first surface 1211 and / or the second surface 3211, or tangency due to contact between the first surface 1211 and the second surface 3211. Furthermore, tangency includes internal tangency (e.g., ...). Figure 32 (as shown) or external incision (such as) Figure 2 , Figure 7 as well as Figure 15 (As shown).
[0091] Optionally, in some embodiments, the first curved surface 1211 is a first arc surface, the second curved surface 3211 is a second arc surface, and the arc length corresponding to the second arc surface can be tangent to the arc length corresponding to the first arc surface.
[0092] Optionally, such as Figure 2 as well as Figure 7 As shown, the first surface 121 also includes a first plane 1213 that smoothly transitions with the first arcuate surface. (Ref) Figure 2 As shown, a portion of the plane of the cover component 200 is disposed on the first surface 121.
[0093] like Figures 11 to 16 As shown, in some embodiments, the first surface 1211 is a partial sphere, the second surface 3211 is a partial sphere, and the sphere corresponding to the second surface 3211 can be tangent to the sphere corresponding to the first surface 1211.
[0094] See you later Figures 3 to 7 As shown, in some embodiments, the first curved surface 1211 is provided with a first notch 1212, and a portion of the traction body 320 is embedded in the first notch 1212 so that the second curved surface 3211 and the first curved surface 1211 are smoothly connected. Thus, by partially embedding the traction body 320 into the first notch 1212, the traction body 320 and the limiting body 120 fit more tightly, and the smooth connection between the second curved surface 3211 and the first curved surface 1211 makes the connection between the traction member 300 and the support member 100 smoother, further reducing the feeling of foreign objects and improving user experience and wearing comfort.
[0095] like Figures 9 to 13As shown, in other embodiments, the first surface 121 and the second surface 321 transition smoothly. This also achieves a smooth connection between the first surface 121 and the second surface 321, reducing discomfort and discomfort, thus improving user experience and wearing comfort.
[0096] Furthermore, such as Figures 9 to 13 As shown, in some embodiments, the first surface 121 includes a first plane 1213 and a second notch 1214 adjacent to the first plane 1213. The second surface 321 is provided with a second plane 3212. A portion of the traction body 320 is embedded in the second notch 1214 so that the first plane 1213 and the second plane 3212 are smoothly connected. In this way, by partially embedding the traction body 320 in the second notch 1214, the traction body 320 and the limiting body 120 fit more tightly, and by smoothly connecting the second plane 3212 with the first plane 1213, the connection between the traction member 300 and the bracket member 100 is smoother and more seamless, further reducing the feeling of foreign objects and improving the user experience and user wearing comfort.
[0097] Optionally, in some embodiments, the cover 200 includes a fourth surface 210 that smoothly connects with the first surface 121. Thus, the cover 200 and the bracket 100 transition smoothly, making the orthodontic appliance 10 smoother overall with no obvious sharp edges, further reducing the feeling of foreign objects, improving user experience and wearing comfort.
[0098] In combination with any of the above embodiments, such as Figure 2 as well as Figure 3 As shown, or as Figure 14 as well as Figure 15 As shown, in some embodiments, the traction body 320 further includes a first mating surface 322, which is adjacent to and smoothly transitions with the second surface 321. At least a portion of the first mating surface 322 is in contact with the limiting body 120, so that at least a portion of the first surface 121 and at least a portion of the second surface 321 are smoothly connected. Thus, by having at least a portion of the first mating surface 322 in contact with the limiting body 120, the traction body 320 and the limiting body 120 are more tightly fitted, and by having the second plane 3212 smoothly connect with the first plane 1213, the connection between the traction member 300 and the bracket member 100 is smoother and more seamless, further reducing the feeling of foreign objects and improving the user experience and wearing comfort.
[0099] In addition, since the traction body 320 contacts the limiting body 120 through the first mating surface 322, it is convenient to realize the limiting fit between the traction body 320 and the limiting body 120.
[0100] Optionally, such as Figures 14 to 20 As shown, or Figures 21 to 24As shown, in some embodiments, the first mating surface 322 is adapted to and adheres to the first surface 121, so that at least a portion of the first surface 121 smoothly connects with at least a portion of the second surface 321. Thus, the first mating surface 322 directly adheres to the first surface 121, allowing the second surface 321 to better smoothly transition according to the extension direction of the first surface 121. This also helps to increase the area of the second surface 321 connecting to the first surface 121, further reducing the feeling of foreign matter.
[0101] In conjunction with any embodiment of the first mating surface 322 described above, such as Figure 16 as well as Figure 17 As shown, or as Figure 18 As shown, in some embodiments, a recess 10b is formed between the smooth transition between the first mating surface 322 and the second surface 321 and the limiting body 120. Thus, the recess 10b is allowed at the junction of the first surface 121 and the second surface 321, which can reduce the manufacturing difficulty and assembly accuracy of the bracket 100 and the traction member 300, and reduce the manufacturing cost of the orthodontic appliance 10.
[0102] Optionally, in some embodiments, the maximum width of the recess 10b is L1, where 0 ≤ L1 ≤ 0.7 mm. This reduces the likelihood of a foreign body sensation in the first direction.
[0103] Optionally, 0.1mm ≤ L1 ≤ 0.6mm. Optionally, 0.2mm ≤ L1 ≤ 0.5mm. Optionally, 0.3mm ≤ L1 ≤ 0.6mm.
[0104] Optionally, L1 = 0.1mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.62mm, 0.7mm.
[0105] It should be noted that, as Figures 13 to 15 As shown, the width of the recess 10b can be understood as the gap between the traction body 320 and the limiting body 120 after the traction member 300 and the bracket member 100 are connected in place. For example, in the first direction, that is, the X-axis direction, the gap between the traction body 320 and the limiting body 120 at the same height position in the first direction is the width of the recess 10b. The maximum width of the recess 10b is also the maximum gap between the traction body 320 and the limiting body 120.
[0106] like Figure 14 as well as Figure 15As shown, in some embodiments, the limiting body 120 and / or the body 200 are provided with grooves, which form an opening slot 101 when the cover body is in the closed state. The maximum width of the recess 10b is less than the maximum width of the opening slot 101. In this way, the opening slot 101 is fully utilized to limit the recess 10b, making the recess 10b less likely to produce a foreign object sensation in the first direction.
[0107] like Figure 16 or Figure 21 As shown, the maximum width of the opening slot 101 is H1.
[0108] In combination with any of the above embodiments, such as Figure 2 , Figure 15 or Figure 22 As shown, in some embodiments, the traction body 320 further includes a third surface 323 disposed below the second surface 321 and a first side surface 324 disposed between the third surface 323 and the second surface 321, with the first side surface 324 smoothly transitioning to the first surface 121. This ensures a smooth connection between the traction body 320 and the limiting body, further improving user experience and wearing comfort.
[0109] like Figure 20 As shown, in some embodiments, the third surface 323 and the first side surface 324 are smoothly transitioned. This makes the traction body 320 more rounded and smooth, without obvious sharp edges, reducing the feeling of foreign objects and improving the user's comfort when wearing the orthodontic appliance 10.
[0110] In some embodiments, the third surface 323 transitions smoothly with the first surface 121. This makes the traction body 320 more rounded and smooth, without obvious sharp edges, reducing the feeling of foreign objects and improving the user's comfort when wearing the orthodontic appliance 10.
[0111] Optionally, such as Figure 21 As shown, in some embodiments, a portion of the first side surface 324 is spaced apart from the limiting body 120 along the first direction to form a first hook groove 3241. This facilitates the use of the first limiting body 120 and the end of the traction body 320 to form the first hook groove 3241, which is convenient for binding the traction object (e.g., ligating wire).
[0112] like Figure 3 , Figure 14 , Figure 17 or Figure 25 As shown, in some embodiments, at least a portion of the first side surface 324 is recessed to form a second hook groove 3242. Thus, the traction body 320 forms the second hook groove 3242, facilitating the securing of the traction object (e.g., ligating wire). Furthermore, it is not limited by the outer surface shape of the restraining body 120, increasing the design flexibility of the traction member 300.
[0113] Optionally, such as Figure 33 As shown, the first hook groove 3241 is connected to the second hook groove 3242, which facilitates the accommodation of more and / or larger traction objects (such as ligature wires), and makes it convenient to fix the traction objects (such as ligature wires) to the traction body 320.
[0114] It should be noted that the suspended end of the traction body 320 is provided with a hook groove on at least one side to achieve traction.
[0115] like Figure 17 As shown, in some embodiments, the first side surface 324 includes two sides, which are spaced apart on both sides of the second surface 321. This facilitates the formation of grooves on both sides of the traction body 320.
[0116] Furthermore, two hook grooves are formed by the two first side surfaces 324, enabling the traction component to pull in both near-center and far-center directions. When the suspended end not only protrudes but also bends inward and hooks back, the risk of the towed object falling off is reduced.
[0117] like Figure 23 As shown in Figure 24, in some embodiments, the second surface 321 and the first side surface 324 have a smooth transition. This makes the traction body 320 more rounded and smooth, without obvious sharp edges, reducing the feeling of foreign objects and improving the user's comfort when wearing the orthodontic appliance 10.
[0118] In some embodiments, the second surface 321 and the third surface 323 are smoothly transitioned. This makes the traction body 320 more rounded and smooth, without obvious sharp edges, reducing the feeling of foreign objects and improving the user's comfort when wearing the orthodontic appliance 10.
[0119] In combination with any of the above embodiments, such as Figure 15 , Figure 22 or Figure 26 As shown, in some embodiments, the traction body 320 further includes an end face 325 adjacent to the second surface 321, with the second surface 321 and the end face 325 smoothly transitioning. This smooth transition between the second surface 321 and the end face 325 makes the end of the traction body 320 smoothly transition, reducing the likelihood of a foreign body sensation during the user's wearing of the orthodontic appliance 10, thus improving the user experience and wearing comfort.
[0120] like Figure 12 , Figure 22 or Figure 26 As shown, in some embodiments, the end face 325 is composed of an arc surface, a spherical surface, a plane, or a combination of at least two. This allows for flexible rotation as needed.
[0121] Optionally, such as Figures 26 to 30 As shown, in some embodiments, the end face 325 is spherical and cooperates with the limiting body to form a hook groove.
[0122] It should be noted that there are various ways to achieve the detachable connection between the connector 310 and the bracket 100, including but not limited to adhesive fixing, screw fixing, tenon fixing, snap fixing, etc., and any traditional technology that meets the requirements of this application can be used.
[0123] In combination with any of the above embodiments, such as Figure 2 As shown, in some embodiments, the carrier 110 is provided with a connecting recess 111, and at least a portion of the connector 310 is inserted into the connecting recess 111. Thus, the insertion of at least a portion of the connector 310 into the connecting recess 111 secures the traction member 300 to the bracket member 100, minimizing or eliminating the external space occupied by the traction member 300, reducing the feeling of foreign objects, and improving the user's comfort when wearing the orthodontic appliance 10.
[0124] Optionally, such as Figure 15 , Figure 22 or Figure 27 As shown, in some embodiments, the connecting recess 111 includes a connecting hole 1111, and the limiting body 120 is provided with a clearance hole 122 communicating with the connecting hole 1111. The connecting body 310 includes a first insert body 311 that engages with the connecting hole 1111 and a reinforcing rib 312 that connects to the first insert body 311 and the traction body 320. The reinforcing rib 312 is embedded in the clearance hole 122. Thus, by inserting the first insert body 311 into the connecting hole 1111, the traction member 300 and the bracket member 100 are fixed, making the traction member 300 and the bracket member 100 fit tightly, reducing the feeling of foreign objects, and improving the comfort of the user wearing the orthodontic appliance 10.
[0125] By setting the reinforcing rib 312, the connection strength between the connector 310 and the traction body 320 can be improved, ensuring that the traction body 320 can reliably pull the towed object. The reinforcing rib 312 is embedded in the clearance hole 122, which makes the traction component 300 and the bracket component 100 fit tightly and reduces the feeling of foreign objects.
[0126] Optionally, such as Figure 32 As shown, in some embodiments, the connecting recess 111 includes at least two slots spaced apart from the carrier 110, and the connecting body 310 includes a latch 313 corresponding to each of the at least two slots. The latch 313 is inserted into the slot and engages with the carrier 110. Thus, by inserting the latch 313 into the slot and engaging with the carrier 110, the traction member 300 and the bracket member 100 are easily fixed together, facilitating easy assembly and disassembly. Furthermore, using slots to accommodate the latch 313 ensures a tight fit between the traction member 300 and the bracket member 100, reducing the feeling of foreign objects and improving the user's comfort when wearing the orthodontic appliance 10.
[0127] like Figure 33As shown, in some embodiments, a hook groove is provided between the traction body 320 and the limiting body 120. The orthodontic appliance 10 also includes a locking member 400, which includes a buckle body 410 and a pressing body 420 fixedly connected to the buckle body 410. The buckle body 410 engages with the hook groove to fix the pressing body 420 in the archwire groove 140. At least a portion of the buckle body 410 smoothly connects to the first surface 121 and / or the second surface 321. In this way, the locking member 400 is securely connected to the orthodontic appliance 10 through the buckle body 410, and the pressing body 420 is used to press the archwire 20, making it easy to fix the archwire 20.
[0128] At least a portion of the buckle 410 smoothly connects with the first surface 121 and / or the second surface 321, making the connection between the locking member 400 and the limiting body 120 and / or the traction body 320 smooth. This reduces the feeling of foreign objects during the user's wearing of the orthodontic appliance 10, thus improving the user experience and wearing comfort.
[0129] In conjunction with the aforementioned embodiments of the first and second hook grooves, such as Figure 33 As shown, in some embodiments, a portion of the first side surface 324 is spaced apart from the limiting body 120 along a first direction to form a first hook groove 3241. At least a portion of the first side surface 324 is recessed to form a second hook groove 3242, which communicates with the first hook groove 3241 to form a hook groove.
[0130] In some embodiments, the orthodontic appliance also includes a locking element (not shown) that cooperates with the bracket to at least secure the cover element in a closed state.
[0131] It should be noted that there are various ways to implement the locking mechanism, including but not limited to screw locking, elastic locking, etc., which can be achieved in traditional technologies and will not be elaborated on here.
[0132] Optionally, the carrier includes a base. This facilitates a secure connection between the base and the teeth.
[0133] It should be noted that the "fitting body" can be "part of the bracket", that is, the "fitting body" is integrally formed with "other parts of the bracket, such as the carrier"; or it can be an independent component that can be separated from "other parts of the bracket, such as the carrier", that is, the "fitting body" can be manufactured independently and then combined with "other parts of the bracket, such as the carrier" to form a whole.
[0134] Equivalently, "a certain body" or "a certain part" can be a portion of the corresponding "component," meaning that "a certain body" or "a certain part" is integrally formed and manufactured with the "other parts of the component"; or it can be an independent component that can be separated from the "other parts of the component," meaning that "a certain body" or "a certain part" can be manufactured independently and then combined with the "other parts of the component" to form a whole. The expression of "a certain body" or "a certain part" in this application is merely one embodiment for ease of reading, and is not intended to limit the scope of protection of this application.
