bracket

Abstract

This utility model relates to a support bracket, comprising a main body, a cover, a support member, and a push plate. A receiving groove is formed on the bottom surface of the archwire groove, and the push plate is disposed within the receiving groove. A mounting groove is located below the receiving groove and is connected to the archwire groove through the receiving groove. The other end of the support member passes through the mounting groove and is bent. The support member, connecting part, and mating part together encircle the main body. The middle section of the support member abuts against the push plate, causing the push plate to move or deform towards the archwire groove, thereby achieving the purpose of locking the archwire or reducing clearance. In this application, locking or reducing clearance is achieved by inserting one end of the support member into the mounting groove, thereby forcing the push plate to move or deform towards the archwire groove. The support member, connecting part, and mating part together encircle the main body, eliminating the need for threads on the support member, greatly reducing manufacturing difficulty and cost. Furthermore, the push plate has a plate-like structure, resulting in a larger contact area with the archwire and better locking or clearance reduction effects.

Description

Technical Field

[0001] This utility model relates to the field of orthodontic treatment technology, and in particular to a bracket. Background Technology

[0002] Brackets are mainly used in orthodontic treatment to help teeth move to the ideal position. They are suitable for various malocclusions, such as crowded teeth, gaps, and reverse bite.

[0003] In the process of orthodontic treatment using brackets, the process usually involves steps such as alignment and leveling, closing gaps, and fine-tuning. In these steps, it is often necessary to reduce the clearance between the archwire and the archwire slot or to prevent relative movement between the archwire and the archwire slot (also known as locking) in order to better express data such as torque, compensation, axial tilt, and clearance, and improve the efficiency of orthodontic treatment.

[0004] Existing guide rails, such as the Chinese patent with publication number CN209645107U, disclose a traction hook comprising an integrally formed ball hook head, hook arm, and limiting arm. This traction hook is used to adjust the vertical displacement of the square wire within the bow wire groove, thereby reducing clearance and preventing locking. However, this solution's effect on reducing clearance or preventing locking is not ideal.

[0005] Other types of brackets, such as the Chinese patent with publication number CN109091254B, disclose an adjustment mechanism connected to an adjustment plate for locking and reducing clearance. The adjustment mechanism includes a rod-shaped drive rod, with a connector at the end of the drive rod fixedly connected to the adjustment plate. The drive rod is a threaded rod, with a connector at the end of the threaded rod connecting to the adjustment plate. Because the bracket itself is very small, with an overall size of only about 2mm-4mm, and the threaded rod is even smaller at the micrometer level, this solution has a complex manufacturing process and high cost. Utility Model Content

[0006] Therefore, it is necessary to provide a bracket that reduces clearance and has a better locking effect, while also being simple to manufacture and low in cost, to address the aforementioned technical problems.

[0007] A bracket, comprising:

[0008] The main body is provided with an archwire groove that runs through the main body in a mesiodistal direction. The archwire groove divides the main body into a first end and a second end. A receiving groove is formed on the bottom surface of the archwire groove. The main body is also provided with an installation groove located below the receiving groove. The installation groove runs through the gingival-maxillary direction of the main body and is connected to the archwire groove through the receiving groove.

[0009] A cover portion is movably disposed on the second end, and the cover portion can open or close the bowwire groove;

[0010] The support member includes a support portion, a connecting portion, and a mating portion. One end of the support portion is connected to one end of the connecting portion, and one end of the mating portion is connected to the other end of the connecting portion. The other end of the support portion can be bent after passing through the mounting groove. The support portion, connecting portion, and mating portion together encircle the main body portion.

[0011] A push plate is disposed in the receiving groove. The middle section of the support part can abut against the push plate to move the push plate toward the bow wire groove and / or deform it, thereby reducing clearance or locking.

[0012] In one embodiment, the receiving groove extends along the mesiodistal direction of the archwire groove, and the pusher plate is elongated and extends along the mesiodistal direction of the archwire groove and is adapted to the receiving groove.

[0013] In one embodiment, the opposite side walls of the receiving groove are provided with slots, and the opposite ends of the push plate are provided with protrusions, the protrusions cooperating with the slots; or

[0014] The receiving groove has protrusions on its opposite side walls, and the push plate has slots on its opposite ends, with the slots engaging with the protrusions.

[0015] In one embodiment, the top surface of the support is a slope, and gradually decreases in the direction away from the connecting portion; and / or

[0016] The supporting part has the same structure as the mating part and is symmetrically arranged with respect to the centerline of the mating part; or

[0017] The supporting part and the mating part have different structures, and the length of the supporting part is greater than that of the mating part.

[0018] In one embodiment, the main body is further provided with a through-gingual groove, the through-gingual groove being spaced apart from the mounting groove and communicating with the receiving groove. The mating part passes through the mating groove, and the middle section of the mating part can abut against the push plate to move the push plate closer to the archwire groove and / or deform it, thereby reducing clearance or locking.

[0019] The main body is also provided with a mating groove that runs through its gingival direction. The mating groove is spaced apart from the mounting groove and is not connected to the receiving groove. The mating part passes through the mating groove.

[0020] In one embodiment, the connecting portion is provided with an elastic portion that can abut against the main body portion to eliminate the misalignment caused by bending at the other end of the support portion.

[0021] In one embodiment, a traction hook is provided on the side of the first end facing away from the second end. The lip side of the traction hook is an arc surface, and the lip side of the first end is an arc surface. The lip side of the traction hook and the lip side of the first end are smoothly connected and the traction hook is integrally formed with the first end.

[0022] In one embodiment, the traction hook includes a traction portion and an extension portion. The traction portion has a connecting end and a suspended end. The connecting end of the traction portion is integrally formed with the first end. The extension portion is disposed at the suspended end of the traction portion and extends along the proximal-distal direction.

[0023] In one embodiment, the suspended end of the traction hook is closer to the tongue side than the connecting end.

[0024] In one embodiment, a base plate is further included, which is disposed on the bottom surface of the main body, and a ligation groove is formed between the base plate and the first end and the second end, with the support portion located within the ligation groove.

[0025] The above-mentioned brackets have at least the following advantages:

[0026] Because the bottom surface of the bowwire groove has a receiving groove, the push plate is set in the receiving groove, and the mounting groove is located below the receiving groove and connected to the bowwire groove through the receiving groove, when it is necessary to lock the bowwire or reduce clearance, the support is installed on the main body. Specifically, the other end of the support is passed through the mounting groove and bent. At this time, the support, connecting part, and mating part together surround the main body. The middle section of the support abuts against the push plate, causing the push plate to move or deform towards the bowwire groove, thereby achieving the purpose of locking the bowwire or reducing clearance. Because in this application, locking or reducing clearance is achieved by inserting one end of the support of the support into the mounting groove, thereby forcing the push plate to move or deform towards the bowwire groove, and the support, connecting part, and mating part together surround the main body, there is no need to set threads on the support, which greatly reduces the manufacturing difficulty and cost. Moreover, the push plate is a plate structure with a larger contact area with the bowwire, so the locking or clearance reduction effect is better. Attached Figure Description

[0041] Unless otherwise stated, the following structural description requires the use of a frame of reference for the maxillary teeth to describe embodiments of the present invention. Therefore, as used herein, terms such as labial, lingual, mesial, distal, occlusal, and gingival, used to describe brackets, are relative to the selected frame of reference. However, embodiments of the present invention are not limited to the selected frame of reference and the terms used, as brackets can be used on other teeth in the oral cavity and in other directions.

[0042] For example, brackets can also be coupled to the lingual surface of teeth and fall within the scope of this invention. Those skilled in the art will recognize that the descriptive terms used herein may not be directly applicable when there are changes in the frame of reference. However, embodiments of this invention are intended to be independent of position and orientation within the oral cavity, and the related terminology used to describe the embodiments is merely to provide clear illustration of the embodiments in the drawings. Similarly, the related terms labial, lingual, mesial, distal, occlusal, and gingival in no way limit this invention to a particular position or orientation.

[0043] The terms labial, lingual, mesial, distal, occlusal, and gingival are industry terms used in orthodontic treatment. Taking an upper jaw tooth as an example, the tooth surface can be roughly divided into six surfaces. The surface of the tooth that occludes with the lower jaw teeth is the occlusal surface; the surface of the tooth that connects to the attached gingival tissue is the gingival surface; the occlusal surface and the gingival surface are opposite each other, and the direction formed by the occlusal surface and the gingival surface is also called the gingio-occlusal direction. The surface of the tooth facing the lips is the labial surface, and the surface of the tooth facing the tongue is the lingual surface; the labial surface and the lingual surface are opposite each other, and the direction formed by the labial surface and the lingual surface is also called the labiolingual direction. The two surfaces of the tooth that contact adjacent teeth are the mesial surface and the distal surface, the difference being their distance from the center; the direction formed by the two is also called the mesiodistal direction, or mesiodistal direction.

[0044] Furthermore, in the description of direction, "lip-tongue direction" generally refers to two directions. However, "lip-tongue direction" specifically refers to a single direction, that is, from the side of the lips to the side of the tongue, and this is used to distinguish them.

[0045] Please see Figures 1 to 10In one embodiment, the bracket 10 includes a main body 100, a cover 200, a support 300, a push plate 400, an elastic self-locking member (not shown), and a base plate 500. Specifically, the main body 100 is provided with an archwire groove 110, which extends through the main body 100 along the mesiodistal direction. The archwire groove 110 is mainly used to accommodate the archwire 20. Because different orthodontic steps require archwires 20 with different cross-sectional shapes (e.g., square archwires with a square cross-section, circular archwires with a circular cross-section) and different sizes, the size of the archwire groove 110 is usually designed to be larger than the size of the archwire 20. This size mainly refers to the width in the gingival-occlusal direction and the height in the labiolingual direction. It is precisely because the size of the archwire groove 110 is larger than the size of the archwire 20 that a locking function or a reduction in clearance is needed to better express data and thus improve orthodontic efficiency.

[0046] It should be noted that you should refer to [link / reference]. Figure 6 The locking function referred to in this application mainly refers to the push plate 400 pressing against the bow wire 20, preventing the bow wire 20 from moving or rotating within the bow wire groove 110. Please refer to... Figure 5 The reduction of clearance referred to in this application mainly means that the push plate 400 does not completely abut against the bow wire 20, but occupies part of the space of the bow wire groove 110 by means of the push plate 400, thereby reducing the effective space of the bow wire groove 110. There is still a certain clearance between the bow wire 20 and the cover plate. At this time, the bow wire 20 can move or rotate in the bow wire groove 110, but the degree of this movement or rotation is smaller than when the push plate 400 is not provided.

[0047] Please see Figure 3 The archwire groove 110 divides the main body 100 into a first end 120 and a second end 130. A cover 200 is movably disposed on the second end 130, and the cover 200 can open or close the archwire groove 110. For example, the cover 200 can be slidably disposed on the second end 130 to move closer to or further away from the first end 120, thereby closing or opening the archwire groove 110. An elastic self-locking member is disposed on the second end 130, with one end protruding from the second end 130. Correspondingly, the bottom surface of the cover 200 is provided with a locking groove (not shown) that cooperates with the elastic self-locking member. It should be noted that the structure of the elastic self-locking member and the locking groove can adopt a structure that can achieve self-locking in the prior art, which is not the inventive point of this application.

[0048] In this embodiment, the first end portion 120 is slightly higher than the second end portion 130. This allows the cover portion 200 to fully cover the archwire groove 110 after assembly onto the second end portion 130. This increases the effective contact length between the cover portion 200 and the archwire 20, better representing the data of the archwire 20 and further improving treatment efficiency. Furthermore, the reduced exposed area of ​​the archwire groove 110 prevents food residue and improves oral hygiene. Of course, in other embodiments, the cover portion 200 can also be rotatably mounted on the second end portion 130, and the first end portion 120 can be flush with the second end portion 130.

[0049] The bottom surface of the archwire groove 110 is provided with a receiving groove 140, which is mainly used to accommodate the push plate 400. The main body 100 is also provided with a mounting groove 150, located below the receiving groove 140. The mounting groove 150 penetrates the gingival-maxillary direction of the main body 100 and is connected to the archwire groove 110 through the receiving groove 140. Furthermore, the mounting groove 150 also penetrates the bottom surface of the main body 100. A base plate 500 is disposed on the bottom surface of the main body 100. Therefore, after the base plate 500 is fixed to the bottom surface of the main body 100, the mounting groove 150 forms a through-hole structure. From the perspective of the injection molding process of the bracket 10, designing the mounting groove 150 to penetrate the bottom surface of the main body 100 is more conducive to demolding and reduces manufacturing difficulty. Of course, in other embodiments, the mounting groove 150 may not penetrate the bottom surface of the main body 100.

[0050] Please see Figure 8 and 9 The support member 300 includes a support portion 310, a connecting portion 320, and a mating portion 330. One end of the support portion 310 is connected to one end of the connecting portion 320, and one end of the mating portion 330 is connected to the other end of the connecting portion 320. That is, the support portion 310 and the mating portion 330 are respectively connected to opposite ends of the connecting portion 320. For example, in this embodiment, the support portion 310, the connecting portion 320, and the mating portion 330 are integrally formed. Please refer to [further details omitted]. Figure 2 , 4 and Figure 7 The other end of the support part 310 can be bent after passing through the mounting groove 150, and the support part 310, the connecting part 320 and the mating part 330 together surround the main body part 100.

[0051] Specifically, the main body 100 is also provided with a mating groove 160 extending through its gingival direction. The mating groove 160 is spaced apart from the mounting groove 150 and is connected to the receiving groove 140. The support part 310 passes through the mounting groove 150, and the mating part 330 passes through the mating groove 160. The middle section of the mating part 330 can also abut against the push plate 400 to move the push plate 400 towards the archwire groove 110 and / or deform it, thereby reducing clearance or preventing locking. By having the support part 310 and the mating part 330 press against the archwire from both sides, the locking effect is better. Of course, in other embodiments, the main body is provided with a mating groove extending through its gingival direction, the mating groove is spaced apart from the mounting groove, and the mating groove is not connected to the receiving groove. The mating part passes through the mating groove. In this case, the mating part cannot be used to lock the archwire. Of course, in other embodiments, the mating groove 160 may not be provided, the mating part 330 may be directly provided on the outside of the main body 100, and the other end of the support part 310 may pass through the mounting groove 150 and be bent to encircle the main body 100 together with the mating part 330 and the connecting part 320.

[0052] Furthermore, the top surface of the support portion 310 can be an inclined surface that gradually decreases in the direction away from the connecting portion 320. This not only facilitates the insertion of the support member 300 into the mounting groove 150, but also allows for fine adjustment of the distance the push plate 400 moves up and down or the extent of its deformation, thereby fine-tuning the tightness of the push plate 400 against the bow wire 20. Of course, in other embodiments, the top surface of the support portion can also be a flat surface or an arc surface, etc.

[0053] Specifically, in this embodiment, the support portion 310 and the mating portion 330 have different structures. The length of the support portion 310 is greater than that of the mating portion 330. Therefore, only the end of the support portion 310 that passes through the mounting groove 150 can be bent, which improves the ease of operation for doctors. After bending, the support portion 310, the connecting portion 320, and the mating portion 330 together encircle the main body 100, and the support portion 310 will not detach from the main body 100. Of course, in other embodiments, the support portion 310 can also have the same structure as the mating portion 330, and the two can be symmetrically arranged with respect to the centerline of the mating portion 330. In this design structure, the end of the support portion 310 that passes through the mounting groove 150 and the end of the mating portion 330 that is away from the connecting portion 320 can both be bent. After bending, the support portion 310, the connecting portion 320, and the mating portion 330 together encircle the main body 100, and the support portion 310 will not detach from the main body 100.

[0054] Please see Figure 8 and Figure 9Specifically, in this embodiment, the connecting portion 320 is further provided with an elastic portion 340. The elastic portion 340 can abut against the main body portion 100 to eliminate the gap caused by bending the other end of the support portion 310, so that the support member 300 will not move with a gap in the gingival-maxillary direction after the other end of the support portion 310 is bent. For example, the elastic portion 340 can be integrally formed with the connecting portion 320. The connecting portion 320 protrudes to the side facing the main body portion 100 to form a protrusion, and a part of the protrusion is hollowed out to form the elastic portion 340. Alternatively, in other embodiments, the elastic portion 340 can be directly provided on the side of the connecting portion facing the main body portion 100 to achieve the purpose of eliminating the gap.

[0055] Please see Figure 3 , 5 In section 6, the push plate 400 is disposed within the receiving groove 140. The middle section of the support portion 310 can abut against the push plate 400 to allow the push plate 400 to move towards the archwire groove 110 and / or deform, thereby achieving the purpose of locking the archwire 20 or reducing clearance. Specifically, the receiving groove 140 extends along the mesiodistal direction of the archwire groove 110, and the push plate 400 is elongated, extending along the mesiodistal direction of the archwire groove 110 and fitting into the receiving groove 140. Therefore, the push plate 400 is approximately parallel to the extending direction of the archwire 20 and the archwire groove 110. Thus, when the push plate 400 performs locking or clearance reduction, the contact area between the push plate 400 and the archwire 20 is larger than that of the structure mentioned in the background art, resulting in better locking or clearance reduction effects, more accurate data expression, and improved orthodontic efficiency. Of course, in other embodiments, the pusher plate can also be a square plate, a circular plate, or a plate structure of other shapes, as long as it can achieve the purpose of increasing the contact area with the bowwire.

[0056] It should be noted that the intermediate section between the support part 310 and the mating part 330 should be interpreted broadly. The intermediate section between the support part 310 and the mating part 330 does not refer to an absolute intermediate section, but should also include a general intermediate section, as long as it achieves the purpose of this application. It should also be noted that the push plate should be interpreted broadly. The push plate not only includes cases with a cross-section of square, rectangle, or parallelogram, but also cases where only the side of the push plate in contact with the archwire is flat, while other surfaces not in contact with the archwire are non-flat, curved, etc.

[0057] Please see Figure 10Specifically, slots (not shown) can be provided on opposite side walls of the receiving groove 140, and protrusions 410 can be provided on opposite ends of the push plate 400. The push plate 400 is positioned in the receiving groove 140 through the engagement of the protrusions 410 and the slots. This structure makes it less likely for the push plate 400 to fall off after being installed in the receiving groove 140. Of course, in other embodiments, protrusions can also be provided on opposite side walls of the receiving groove 140, and slots can be provided on opposite ends of the push plate 400. The push plate 400 is positioned in the receiving groove 140 through the engagement of the protrusions and slots.

[0058] A base plate 500 is disposed on the bottom surface of the main body 100, and a ligation groove 510 is formed between the base plate 500 and the first end 120 and the second end 130. The support member 300 is partially located in the ligation groove 510. For example, the connecting part 320 of the support member is located in the ligation groove, and the part of the support member 310 that is bent after passing through the mounting groove is located in another ligation groove.

[0059] In some embodiments, a traction hook (not shown) is provided on the side of the first end 120 facing away from the second end 130. The traction hook is mainly used to attach traction accessories (such as rubber bands or springs) to achieve the traction function and move two adjacent teeth with a large gap to a reasonable position. The lip side of the traction hook is an arc surface, and the lip side of the first end 120 is also an arc surface. The lip side of the traction hook and the lip side of the first end 120 are smoothly connected and integrally formed with the first end 120. The traction hook includes a traction part and an extension part. The traction part has a connecting end and a suspended end. The connecting end of the traction part is integrally formed with the first end 120, and the extension part is provided at the suspended end of the traction part and extends along the mesiodistal direction. The suspended end of the traction hook is closer to the tongue side than the connecting end. Therefore, the traction hook is a comfort traction hook. The traction hook, support member 300, and locking member are separate structures, manufactured separately, reducing manufacturing difficulty.

[0060] The aforementioned bracket 10 has at least the following advantages:

[0061] Since the bottom surface of the bow wire groove 110 has a receiving groove 140, the push plate 400 is disposed in the receiving groove 140, and the mounting groove 150 is located below the receiving groove 140 and is connected to the bow wire groove 110 through the receiving groove 140, when it is necessary to lock the bow wire 20 or reduce the clearance, the support member 300 is installed on the main body 100. Specifically, the other end of the support member is passed through the mounting groove 150 and bent. At this time, the support member, the connecting member, and the mating member 330 together surround the main body 100. The middle section of the support member abuts against the push plate 400 so that the push plate 400 moves toward the bow wire groove 110 or deforms, thereby achieving the purpose of locking the bow wire 20 or reducing the clearance. Because in this application, the support part of the support member 300 is inserted into the mounting groove 150, thereby forcing the push plate 400 to move or deform in the direction close to the bow wire groove 110 to achieve locking or reduce clearance, and the support part, connecting part and mating part 330 are all wrapped around the main body 100, there is no need to set threads on the support member 300, which greatly reduces the manufacturing difficulty and cost. Moreover, the push plate 400 is a plate structure with a larger contact area with the bow wire 20, so the locking or clearance reduction effect is better.

[0062] The aforementioned bracket 10 has the traction hook designed to be integrally formed with the first end 120, and the traction hook, support member 300, and locking member are separate structures. Therefore, the traction hook can be designed as a comfortable traction hook structure as shown in the figure.
