Description

Technical Field

[0001] This utility model relates to the field of orthodontics, specifically to an orthodontic appliance with a traction element. Background Technology

[0002] In existing technology, orthodontic brackets or buccal tubes include a base plate and a main body. The main body is block-shaped and has a through groove for threading the archwire. Some brackets and buccal tubes also have traction hooks for attaching traction wires or rubber bands to achieve a traction effect.

[0003] Existing traction hooks are generally positioned in the gingival direction of the orthodontic appliance, which causes significant discomfort. To address this technical issue, the applicant has developed brackets with detachable traction hooks and buccal tubes with rotatable, concealable traction hooks, significantly improving the comfort of both products.

[0004] However, whether it is tapping a threaded hole in the bracket to make the traction hook detachable, or setting a pivot on the cheek tube to make the traction hook rotatable and stored, both require extremely high production and processing technology requirements and costs. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an orthodontic device with a traction component that can effectively reduce production and processing requirements and costs.

[0006] An orthodontic appliance with a traction element includes a main body with an archwire channel extending through both sides of the main body. It also includes a traction element fixedly connected to the main body. The traction element includes a connecting portion and a traction portion. One end of the connecting portion is fixedly connected to the main body, and the other end is connected to the traction portion. In an initial configuration, the traction portion of the traction element is attached to or close to the surface of the main body. In a second configuration, the traction element and / or the main body undergo metallic deformation to create a suspension gap between the traction portion of the traction element and the surface of the main body, thereby enabling the traction element to provide traction.

[0007] Compared with existing technologies, this invention offers the following advantages: The orthodontic appliance of this invention has at least an initial form and a second form. In the second form, a suspension gap exists between the traction portion of the traction member and the surface of the main body. Therefore, the traction component of the traction member in the initial form is closer to the surface of the main body than the traction component in the second form. Consequently, the traction component in the initial form does not protrude as much as in the second form, reducing damage to the oral mucosa and avoiding foreign body sensation and discomfort. Furthermore, unlike traditional orthodontic appliances that use threaded holes to make the traction member detachable or a rotating shaft to allow for rotation and concealment, this invention's orthodontic appliance uses metallic deformation to switch forms, resulting in a simple, stable, and low-cost overall structure.

[0008] Furthermore, in the second embodiment where the traction component involves metallic deformation, the deformation occurs in the connecting portion and / or the traction portion. The traction component comprises two parts: a connecting portion and a traction portion. Metallic deformation in either part can create a suspension gap between it and the surface of the main body. Therefore, for different orthodontic appliances, parameters such as the material and radial dimensions of the traction and connecting portions can be appropriately adjusted so that only one part or both of the traction and connecting portions deform, thereby adapting to the needs of different orthodontic appliances.

[0009] Specifically, the traction part and the connecting part are connected at a non-flat angle. The traction part and the connecting part form a bent shape, which is one way to realize the hooking function of the traction component.

[0010] Specifically, the shape of the traction element is generally L-shaped, J-shaped, T-shaped, Y-shaped, or ↑-shaped. For traction elements that form a bent shape, the traction part can have one bend, such as an L-shaped hook, or two bends, such as a T-shaped hook, or even more than three bends.

[0011] Furthermore, the radial dimension of the connecting portion is smaller than that of the traction portion. This is another form of forming the hook function of the traction component.

[0012] Specifically, the shape of the traction component is generally shaped like a ball cap, mushroom, teardrop, T, Y, or ↑.

[0013] Furthermore, the surface of the main body is partially concave, and the concave portion accommodates the traction portion of the traction member in its initial state. By providing a concave portion on the main body to accommodate the traction portion in its initial state, the orthodontic appliance in its initial state becomes more comfortable and free of foreign body sensation.

[0014] Furthermore, in its initial form, the traction portion of the traction element is either completely housed within the concave portion, or partially exposed outside the concave portion. In the embodiment where the traction portion of the traction element is completely housed within the concave portion in its initial form, the initial form of the orthodontic appliance achieves maximum comfort. In the embodiment where the traction portion is partially exposed outside the concave portion in its initial form, while maintaining comfort, the traction element is easier to position and apply force with tools, thus facilitating the doctor's operation.

[0015] Furthermore, the archwire channel divides the main body into two ends, with at least one end recessed to form two independent ligation wings. The traction member is connected to the recessed portion, or in its initial form, the traction portion of the traction member is housed within the recessed portion. The traction member is concealed between the two ligation wings, thus preventing the traction hook from irritating the oral mucosa in its initial form.

[0016] Furthermore, the bowwire channel divides the main body into two ends, with at least one end recessed to form two independent ligation wings. The traction member is connected to either of these ligation wings. In the second configuration, where the main body involves metallic deformation, the ligation wings are the ones undergoing metallic deformation. In the initial configuration, the ligation wings are attached to or near the main body by folding or other means, causing the traction member to adhere to or approach the surface of the main body. When traction is required, the metallic deformation straightens the ligation wings, creating a suspension gap between the traction member and the surface of the main body, thus enabling the traction member to perform traction. During the straightening of the ligation wings, whether or not the traction member itself undergoes metallic deformation is not critical, as long as it does not affect the traction function of the traction member itself.

[0017] Specifically, the orthodontic appliance also has a cover portion, and the archwire channel divides the main body into two ends. The cover portion is slidably connected to one of the ends for closing or opening the archwire channel.

[0018] Specifically, the main body is further provided with a base plate, which is disposed on the bottom surface of the main body; and / or, the overall outline of the main body is hemispherical, semi-ellipsoidal or semi-cylindrical.

[0019] Specifically, the main body and / or traction component are provided with an opening groove for tool positioning and force application, making the doctor's operation faster and easier.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0036] This utility model relates to an orthodontic appliance with a traction component, comprising a main body having an archwire channel passing through both sides of the main body, and a traction component fixedly connected to the main body. The traction component includes a connecting portion and a traction portion. One end of the connecting portion of the traction component is fixedly connected to the main body, and the other end of the connecting portion is connected to the traction portion. In an initial state, the traction portion of the traction component is attached to or close to the surface of the main body. In a second state, the traction component and / or the main body undergo metallic deformation to create a suspension gap between the traction portion of the traction component and the surface of the main body, thereby enabling the traction component to provide traction.

[0037] Example 1

[0038] like Figure 1-5 As shown, Embodiment 1 is a cheek tube with a traction member, including a main body 110 and a traction member 120 fixedly connected to the main body 110. The traction member 120 is fixedly connected to the main body 110. The fixed connection can be welding or integral molding. In Embodiment 1, the main body 110 and the traction member 120 are fixedly connected by welding.

[0039] Specifically, the overall outline of the main body 110 in Embodiment 1 is semi-ellipsoidal. Embodiment 1 is a buccal tube, which is bonded to the molars. The buccal tube is generally a shape close to a transverse cuboid with the major axis greater than the minor axis. This embodiment is semi-ellipsoidal, which is more rounded and comfortable than a general cuboid or roughly rectangular buccal tube. In other embodiments, the orthodontic appliance of this utility model can also be cuboid or semi-cylindrical.

[0040] The main body 110 has a wire channel 111 that runs through both sides of the main body 110. The wire channel 111 divides the main body 110 into two ends, namely a first end 115 and a second end. The bottom of the first end 115 and the bottom of the second end are connected by a base of the main body. The first end 115 is recessed to form two independent ligation wings 113, which are used for wire ligation. The recessed portion 117 between the two ligation wings 113 accommodates the traction member 120 in its initial state. The recessed portion 117 is partially recessed to form a semi-circular notch, which is an opening groove 119 for prying open the traction member 120 with a tool.

[0041] The traction member 120 of Embodiment 1 includes a connecting portion 122 and a traction portion 124. The rod-shaped connecting portion 122 and the rod-shaped traction portion 124 are connected at approximately a right angle to form an L-shape. One end of the connecting portion 122 of the traction member 120 is fixedly connected to the main body 110, and the other end of the connecting portion 122 of the traction member 120 is connected to the traction portion 124.

[0042] In the initial configuration of the orthodontic appliance of Embodiment 1, the traction member 120 is attached to the surface of the main body 110. Specifically, the connecting portion 122 of the traction member 120 is bent, such that the traction portion 124 of the traction member 120 is attached to the concave portion 117 of the main body 110 and corresponds to the opening groove 119 above it.

[0043] In Example 1, the orthodontic appliance is switched from the initial form to the second form. Specifically, a tool, such as a probe, is used to locate the opening groove 119. The tip of the probe applies force to the traction member 120, causing the connecting part 122 of the traction member 120 to deform metallically and reduce the degree of bending. This results in a suspension gap between the traction part 124 and the surface of the main body 110, enabling the traction member 120 to perform the traction function and placing the traction member 120 in a usable state.

[0044] In other embodiments, the traction portion 124 of the traction member 120 in its initial state may not be attached to the surface of the main body 110. The traction portion 124 of the traction member 120 in its initial state may be close to the surface of the main body 110. The difference between close and attached is that close means that the traction portion 124 and the surface of the main body 110 still maintain a certain distance, so that there is a suspension gap between the traction portion of the traction member and the surface of the main body.

[0045] The buccal tube of Embodiment 1 also includes a base plate 130, the surface of which is fixedly connected to the bottom surface of the main body 110. The bottom surface of the base plate 130 is used for bonding to the tooth surface. The base plate 130 helps to increase the contact area between the buccal tube / bracket and the teeth, resulting in a more secure bond. The base plate 130 is widely used as a standard component of orthodontic appliances.

[0046] Compared with existing technologies, the orthodontic appliance of Embodiment 1 has an initial form and a second form. In the second form, there is a suspension gap between the traction portion of the traction member and the surface of the main body. In the initial form, the traction portion of the traction member is closer to the surface of the main body, making it less protruding than in the second form. This can reduce damage to the oral mucosa and avoid foreign body sensation and discomfort to a certain extent. Moreover, unlike traditional orthodontic appliances that use threaded holes to make the traction member detachable or use a rotating shaft to make the traction member rotatable and hidden, the orthodontic appliance of Embodiment 1 switches forms through metallic deformation, making the overall structure simple, stable, and inexpensive.

[0047] In other embodiments, the shape of the traction member is generally J-shaped, T-shaped, Y-shaped, or ↑-shaped, etc. As long as the traction part and the connecting part of the traction member are not connected at a flat angle, traction can be achieved.

[0048] In Embodiment 1 above, only the connecting portion of the traction member undergoes metallic deformation. In other embodiments, when the tool applies force to the traction member, both the connecting portion and the traction portion may undergo metallic deformation simultaneously or sequentially. Taking Embodiment 1 as an example, when the tool applies force to the traction member, the connecting portion of the traction member reduces its bending degree. At the same time, the traction portion, which is perpendicularly connected to the connecting portion, is pulled and deformed, causing the traction portion to connect to the connecting portion at an obtuse angle, resulting in the end of the traction portion curving upwards.

[0049] In other embodiments of traction components with specific shapes, the connecting portion and the traction portion of the traction component are folded, so that the traction portion of the traction component adheres to or is close to the surface of the main body. When the tool applies force to the traction component, only the traction portion of the traction component undergoes metallic deformation. Taking Embodiment 1 as an example, when the tool applies force to the traction component, the connecting portion of the traction component does not reduce its degree of bending. Instead, the traction portion, which is connected at a right angle to the connecting portion, is pulled and deformed, so that the traction portion and the connecting portion are connected at an obtuse angle, resulting in the end of the traction portion curving upwards.

[0050] In this embodiment 1, a notch is provided in the main body to obtain an opening groove for tool positioning. In other embodiments, the position and shape of the opening groove on the main body are adjusted according to the convenience of tool positioning. Furthermore, the opening groove can be provided on the traction member.

[0051] This embodiment 1 presents a cheek tube with a traction member, having an initial form and a second form. However, metallic deformation is a continuous process, and the force applied to the traction member results in a non-unique distance between the traction portion of the traction member and the surface of the main body. Therefore, embodiment 1 may also have a third form, a fourth form, etc. The distance in the third and fourth forms may or may not meet the suspension requirements; the value that meets the suspension requirements may be different from that in the second form, but it can still be used for traction by the traction member. The forms are not limited to the initial form and the second form; the same applies to the following embodiments, and will not be repeated.

[0052] Example 2

[0053] like Figure 6-10 As shown, Embodiment 2 is a tray with a traction member, including a main body 210 and a traction member 220 fixedly connected to the main body 210. The traction member 220 is fixedly connected to the main body 210. The fixed connection can be welding or integral molding. In Embodiment 2, the main body 210 and the traction member 220 are fixedly connected by integral molding.

[0054] Specifically, the overall outline of the main body 210 of Embodiment 2 is a square shape with rounded corners. Embodiment 2 is a bracket, which is bonded to the canine or premolar. The bracket is generally a shape close to a longitudinal cuboid or square with the major axis less than or equal to the minor axis. In this embodiment, it is square. In other embodiments, the orthodontic appliance of this utility model can also be hemispherical, semi-ellipsoidal, or semi-cylindrical, etc.

[0055] The main body 210 has a wire channel 211 that runs through both sides of the main body 210. The wire channel 211 divides the main body 210 into two ends, namely a first end 215 and a second end 216. The bottom of the first end 215 and the bottom of the second end 216 are connected by a base of the main body. The first end 215 is recessed to form a groove 218 for storing the traction member 220 in its initial state.

[0056] The corrector in Embodiment 2 also includes a cover portion 240, and the second end portion 216 of the main body portion 210 is slidably connected to the cover portion 240. The cover portion 240 is used to slide open or close the archwire channel 211.

[0057] The bracket in Embodiment 2 also includes a base plate 230, the surface of which is fixedly connected to the bottom surface of the main body 210, and the bottom surface of the base plate 230 is used to bond to the tooth surface.

[0058] The traction component 220 of Embodiment 2 includes a connecting portion 222 and a traction portion 224. The connecting portion 222, which is bent into an L-shaped rod, and the traction portion 224, which is shaped like a ball cap, are connected to each other. That is, the radial dimension of the connecting portion 222 is smaller than that of the traction portion 224. One end of the connecting portion 222 of the traction component 220 is fixedly connected to the main body 210, and the other end of the connecting portion 222 of the traction component 220 is connected to the traction portion 224.

[0059] In the initial configuration of the orthodontic appliance of Embodiment 2, the traction member 220 is attached to the surface of the main body 210. Specifically, the connecting portion 222 of the traction member 220 is bent, such that the traction portion 224 of the traction member 220 is attached to the concave portion of the main body 210.

[0060] In Example 2, the orthodontic appliance is switched from the initial form to the second form. Specifically, a tool, such as a probe, is used to locate the connecting part 222, which is bent into an L-shaped rod. The tip of the probe applies force to the traction member 220, causing the connecting part 222 of the traction member 220 to undergo metallic deformation and reduce the degree of bending. This results in a suspension gap between the traction part 224 of the traction member 220 and the surface of the main body 210, enabling the traction member 220 to perform the traction function and placing the traction member 220 in a usable state.

[0061] Compared with existing technologies, the orthodontic appliance of Embodiment 2 has an initial form and a second form. In the second form, there is a suspension gap between the traction portion of the traction member and the surface of the main body. Therefore, in the initial form, the traction portion of the traction member is closer to the surface of the main body, making it less protruding than in the second form. This can reduce damage to the oral mucosa and avoid foreign body sensation and discomfort to a certain extent. Moreover, unlike traditional orthodontic appliances that use threaded holes to make the traction member detachable or use a rotating shaft to make the traction member rotatable and hidden, the orthodontic appliance of Embodiment 2 switches states through metallic deformation, making the overall structure simple, stable, and inexpensive.

[0062] In other embodiments, the traction portion of the traction member in the initial state may not be attached to the surface of the main body. The traction portion of the traction member in the initial state may be close to the surface of the main body. The difference between close and attached is that close means that the traction member and the surface of the main body still maintain a certain distance, so that there is a suspension gap between the traction portion of the traction member and the surface of the main body.

[0063] In other embodiments, the traction body is generally mushroom-shaped, teardrop-shaped, T-shaped, Y-shaped, or ↑-shaped. Traction can be achieved as long as the radial dimension of the connecting portion of the traction element is smaller than the traction portion. Comparing Embodiments 1 and 2, in Embodiment 1, the traction portion of the initial traction element is almost completely contained within the concave portion, while in Embodiment 2, the traction portion of the initial traction element is partially exposed outside the concave portion. This design is due to limitations in the shape and size of the traction portion, and also because, in the embodiment where the traction portion is completely contained within the concave portion in the initial form, the initial form of the orthodontic appliance achieves maximum comfort. With the traction portion partially exposed outside the concave portion in the initial form, the traction element is easier to position and apply force with tools, facilitating the doctor's operation, while maintaining comfort.

[0064] Example 3

[0065] like Figure 11-15 As shown, Embodiment 3 is a cheek tube with a traction member, including a main body 310 and a traction member 320 fixedly connected to the main body 310. The traction member 320 is fixedly connected to the main body 310. The fixed connection can be welding or integral molding. In Embodiment 3, the main body 310 and the traction member 320 are fixedly connected by integral molding.

[0066] Specifically, in Embodiment 3, the overall outline of the main body 310 is a rounded square shape. The main body 310 has an archwire channel 311 extending through both sides. The archwire channel 311 divides the main body 310 into two ends. The first end 315 is recessed to form two independent ligation wings 313, which are used for wire ligation. The recessed portion 317 between the two ligation wings 313 connects to the traction member 320.

[0067] The corrector in Embodiment 3 also includes a cover portion 340, and the second end portion 316 of the main body portion 310 is slidably connected to the cover portion 340. The cover portion 340 is used to slide open or close the archwire channel 311.

[0068] The bracket in Embodiment 3 also includes a base plate 330, the surface of which is fixedly connected to the bottom surface of the main body 310, and the bottom surface of the base plate 330 is used to bond to the tooth surface.

[0069] The traction member 320 of Embodiment 3 includes a connecting portion 322 and a traction portion 324. The rod-shaped connecting portion 322 and the rod-shaped traction portion 324 are connected at approximately a right angle to form an L-shape. One end of the connecting portion 322 of the traction member 320 is fixedly connected to the main body 310, and the other end of the connecting portion 322 of the traction member 320 is connected to the traction portion 324.

[0070] In the initial configuration of the orthodontic appliance of Embodiment 3, the traction portion 324 of the traction member 320 is close to the surface of the main body 310. Specifically, the connecting portion of the traction member 320 is attached to the inner side of the ligation wing 313 of the main body 310, the traction portion 324 of the traction member 320 is suspended above the connecting portion 322, and the end of the traction portion 324 points towards the base plate 330.

[0071] In Example 3, the orthodontic appliance is switched from the initial form to the second form. Specifically, a tool, such as a probe, is used to locate the traction portion 324 of the traction member 320. The tip of the probe applies force to the traction member 320, causing metallic deformation at the connection between the connecting portion 322 of the traction member 320 and the traction portion 324, thereby causing the traction portion 324 to twist. This changes the direction of the traction portion 324 of the traction member 320 from pointing towards the base plate 330 to being basically parallel to the base plate 330, thus creating a suspension gap between the traction member 320 and the surface of the main body 310. The traction member 320 can then perform the traction function and is in a usable state.

[0072] Compared with existing technologies, the orthodontic appliance of Embodiment 3 has an initial form and a second form. In the second form, there is a suspension gap between the traction portion of the traction member and the surface of the main body. Therefore, in the initial form, the traction portion of the traction member is closer to the surface of the main body, making it less protruding than in the second form. This can reduce damage to the oral mucosa and avoid foreign body sensation and discomfort to a certain extent. Moreover, unlike traditional orthodontic appliances that use threaded holes to make the traction member detachable or use a rotating shaft to make the traction member rotatable and hidden, the orthodontic appliance of Embodiment 3 switches states through metallic deformation, making the overall structure simple, stable, and inexpensive.

[0073] In other embodiments, the traction portion of the traction member in its initial form may be completely attached to the inner side of the ligature wing of the main body.

[0074] In embodiments 1-3 above, the tool applies force to the traction member, causing metallic deformation and changing its shape. In other embodiments, such as a bracket with a traction member, the main body has an archwire channel running through both sides of the main body, dividing the main body into two ends. The first end is recessed to form two independent ligation wings, and the traction member is connected to the ligation wings, adhering to or close to the surface of the main body. In its initial form, the orthodontic appliance and the ligation wings of the traction member are bent and folded metal sheets. When the orthodontic appliance switches from the initial form to the second form, a tool, such as a probe, is used to position the traction member or the folded ligation wings. The probe tip applies force, causing metallic deformation of the ligation wings and reducing the degree of bending, thereby creating a suspension gap between the traction member and the surface of the main body. The traction member can then perform its traction function and is in a usable state.

[0075] Furthermore, in other embodiments, both the traction member and the main body of the orthodontic appliance undergo metallic deformation to create a suspension gap between the traction member and the surface of the main body. For example, a buccal tube with a traction member has an archwire channel running through both sides of the main body, dividing the main body into two ends. The first end is recessed to form two independent ligature wings, and the traction member is connected to the ligature wings, adhering to or close to the surface of the main body. In the initial form, the ligature wings of the traction member are bent and folded metal sheets, and the traction member is also bent and folded in an L-shape. When the orthodontic appliance switches from the initial form to the second form, a tool such as a probe is used to position the traction member or the folded ligature wings. The probe tip applies force, causing the bent and folded traction member and the bent and folded ligature wings to deform metallically, reducing the degree of bending, thereby creating a suspension gap between the traction member and the surface of the main body. The traction member can then perform its traction function and is in a usable state.

[0076] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
