Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to an orthodontic appliance with a matching locking element, as well as the locking element and orthodontic system. Background Technology

[0002] Orthodontics refers to the correction of teeth, malocclusion, and deformities. Orthodontic treatment mainly uses various orthodontic appliances to adjust the coordination between facial bones, teeth, and the nerves and muscles of the maxillofacial region. This involves correcting abnormal relationships between the upper and lower jawbones, between the upper and lower teeth, between the teeth and jawbones, and between the nerves and muscles connecting them. The ultimate goal is to achieve balance, stability, and aesthetics in the stomatognathic system. Currently used orthodontic appliances mainly include brackets and buccal tubes. Brackets are a crucial component of fixed orthodontic techniques. The archwire applies corrective force to the teeth through the brackets. The main function of the brackets is to fix the archwire, allowing it to better exert its corrective force to achieve the orthodontic goal. Most existing self-ligating brackets consist of a bracket body and a movable cover, insert, or clamp, which is movably connected to the bracket body and used to open and close the archwire slot that holds the archwire.

[0003] Locking of a bracket refers to adjusting the effective movement space of the archwire within the bracket through specific means, so that the archwire within the bracket can express torque more accurately, or even the archwire within the bracket and the archwire groove of the bracket can be pressed together to make the bracket an active bracket, providing locking force.

[0004] The applicant's previous patent application, 202420261787.6, discloses an orthodontic appliance with traction and locking function, which includes a locking structure for an archwire bracket. The traction element penetrates the main body of the bracket at the center of the archwire groove to lock the archwire. However, the locking structure of this patent and its matching orthodontic appliance may have stability issues in terms of fixed connection. Utility Model Content

[0005] Therefore, it is necessary to provide an orthodontic appliance with a matching locking element, as well as the locking element and orthodontic system, to address the above-mentioned technical problems, thereby improving the stability of the connection between the locking element and its matching orthodontic appliance.

[0006] An orthodontic appliance with a matching locking member includes a main body and a cover. The main body has an archwire groove extending through it in a mesiodistal direction, dividing it into a first working wing and a second working wing. The cover is disposed on the second working wing and switches between opening and closing the archwire groove. The main body also has at least one locking groove and at least one auxiliary groove extending generally in a gingival-maxillary direction. The locking groove extends through or through the archwire groove from the surface of the main body and is used to connect a locking block of the locking member, allowing the locking block to enter the archwire groove and lock the archwire. The auxiliary groove extends through two opposite surfaces of the main body and is used to connect a bendable end of the locking member, allowing the bendable end to engage with the main body, thereby fixing the locking member to the main body.

[0007] The above-mentioned orthodontic appliances with locking grooves have at least the following advantages:

[0008] Compared with existing technologies, this utility model features a dual-groove design—a locking groove and an auxiliary groove. The locking groove primarily addresses the locking function, while the auxiliary groove mainly secures the locking component to the main body for a stable connection. This enhances the stability of the connection between the locking component and its matched orthodontic appliance, thereby improving the overall locking effect of the orthodontic appliance.

[0009] Specifically, the locking groove extends from the surface of the first working wing through the bowwire groove; or, the locking groove extends from the surface of the second working wing through the bowwire groove; or, the locking groove extends from the surface of the first working wing or the second working wing through the bowwire groove and into the other of the first working wing and the second working wing; or, the locking groove extends through both the bowwire groove and the surfaces of the first working wing and the second working wing.

[0010] Preferably, the locking groove penetrates one side wall of the bow wire groove, thereby forming a through hole in the side wall of the bow wire groove; or, the locking groove penetrates both one side wall and the bottom wall of the bow wire groove, thereby forming a notch at the bottom corner of the bow wire groove.

[0011] Preferably, the locking groove extends through both one side wall and the bottom wall of the bow wire groove, forming a notch at the bottom corner of the bow wire groove with a height less than 1 / 2 of the bow wire groove height and a width less than 1 / 3 of the bow wire groove width.

[0012] Specifically, there is one locking groove and one auxiliary groove. The locking groove is located on the surface that bisects the main body in the axial tilt direction, and the auxiliary groove is located on one side of the locking groove. The locking groove corresponds to the middle of the bowwire groove and can lock the bowwire within it from the perspective of force balance. Alternatively, the locking groove and the auxiliary groove are located on opposite sides of the surface that bisects the main body in the axial tilt direction. This design reduces the precision requirements for machining the groove and the locking component.

[0013] Specifically, there is one locking groove and two auxiliary grooves. The locking groove is located on the surface that bisects the main body in the axial tilt direction, and the two auxiliary grooves are symmetrically distributed on both sides of the locking groove. Alternatively, there are two locking grooves and one auxiliary groove. The auxiliary groove is located on the surface that bisects the main body in the axial tilt direction, and the two locking grooves are symmetrically distributed on both sides of the auxiliary groove.

[0014] Furthermore, the auxiliary groove does not penetrate or pass through the bowwire groove, or the auxiliary groove does penetrate or pass through the bowwire groove; or, it also includes a base plate, and the inclination angle of the auxiliary groove is the same as the inclination angle of the base plate. When the auxiliary groove does not interfere with the bowwire groove, the auxiliary groove only serves as an accessory structure to stabilize the locking member on the main body; when the auxiliary groove interferes with the bowwire groove, the auxiliary groove also has the function of a locking groove.

[0015] To solve the above-mentioned technical problems, this utility model also provides a locking component to match the above-mentioned orthodontic appliances. The locking component is generally U-shaped and includes a first section, a second section, and a connecting section. The first section is provided with a locking block, which is used to connect the locking groove. The locking block is used to occupy space in the archwire groove to lock the archwire. The second section is provided with a bendable end, which is used to connect the auxiliary groove. After the bendable end is bent, it engages with the main body to fix the locking component on the main body.

[0016] Compared with the prior art, the locking component of this utility model is a U-shaped rod with a simple structure. Its first section is used for locking, and its second section is used to fix the locking component to the main body. The design is ingenious, easy to install and disassemble, and convenient for doctors to operate.

[0017] Specifically, the bendable end extends from and bends from the main body, and is used to clamp the surface of the main body. The connecting section is used to clamp the opposite surface of the main body, thereby enabling the locking member to clamp the main body from the two opposite surfaces. The locking member clamps the main body through the second connecting section, ensuring that the locking member is securely connected to the main body and does not fall off, thus ensuring that the force exerted by the locking member on the bowwire in the bowwire groove is stable and continuous.

[0018] Preferably, the locking block is located at the suspended end of the first segment, and the cross-sectional dimension of the suspended end of the first segment is larger than the cross-sectional dimension of the connecting end of the first segment. This ensures that the contact area of ​​the locking block is large enough to form a locking surface within the bowwire groove, sufficient to lock the bowwire within the bowwire groove. The locking surface formed on the locking block includes the end face and the side face of the suspended end of the first segment.

[0019] Specifically, the bendable end is the suspended end of the second segment, and the cross-sectional dimension of the suspended end of the second segment is smaller than the cross-sectional dimension of the connecting end of the second segment. This makes the bendable end easy to bend and shape.

[0020] Preferably, the connecting section is provided with a traction structure; and / or, the first section is also provided with a bendable end; and / or, the second section is also provided with a locking block.

[0021] To solve the above-mentioned technical problems, an orthodontic system is also provided, including the above-mentioned orthodontic appliance and the above-mentioned locking component. Attached Figure Description

[0046] It should be noted that the orthodontic appliances mentioned in this utility model refer to orthodontic brackets or buccal tubes, or other orthodontic appliances with similar functions and structures.

[0047] 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 orthodontic appliances, 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 described, as orthodontic appliances can be used with other teeth in the oral cavity and in other directions.

[0048] For example, brackets or buccal tubes can also be coupled to the lingual surface of the 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.

[0049] 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.

[0050] 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.

[0051] Example 1

[0052] Please see Figures 1 to 11 The orthodontic system 10 of Embodiment 1 includes at least one orthodontic appliance 100 and a locking member 200, wherein the locking member 200 is detachably installed on the orthodontic appliance 100 to enable the orthodontic appliance 100 to have a locking function. The following description uses an orthodontic bracket as an example of the orthodontic appliance 100.

[0053] Specifically, the orthodontic appliance 100 includes a main body 110 and a cover 120, with the cover 120 movably disposed on the main body 110. In some embodiments, a base plate 130 is further provided on the bottom surface of the main body 110, and the orthodontic appliance 100 can be bonded to the tooth surface by applying adhesive to the base plate 130. Of course, in other embodiments, the orthodontic appliance 100 may also be a buccal tube.

[0054] Furthermore, the main body 110 is provided with an archwire groove 111, which extends through the main body 110 in a mesiodistal direction. The archwire groove 111 is mainly used to hold the archwire 20, which transmits torque to the orthodontic appliance 100, and then to the teeth, causing the teeth to slowly move to the correct position. The archwire groove 111 divides the main body 110 into a first working wing 112 and a second working wing 113. The cover 120 is movably disposed on the second working wing 113, and the cover 120 can open or close the archwire groove 111. In this embodiment, the self-ligating orthodontic bracket, which is relatively common in this technical field, is a sliding cover self-ligating bracket. A slide rail is provided on the surface of the second working wing 113, and a slide rail is provided on the bottom surface of the cover 120. The slide rail and the slide engage, allowing the cover 120 to slide approximately along the gingival direction on the main body 110, thereby opening or closing the archwire groove 111.

[0055] The main body 110 is also provided with a locking groove 114 and an auxiliary groove 115, which extend generally along the gingival-maxillary direction. The locking groove 114 extends through or through the archwire groove 111 from the surface of the first working wing 112 or the second working wing 113, and the auxiliary groove 115 extends through two opposite surfaces of the main body 110. The locking groove 114 and the auxiliary groove 115 are used for detachably connecting the locking member 200. In this preferred embodiment, the locking groove 114 extends through the archwire groove 111 from the surface of the first working wing 112.

[0056] It should be noted that "through" and "through" are two different definitions. When the locking groove 114 penetrates the bowwire groove 111, it means that the locking groove 114 only connects to one side wall of the bowwire groove 111, extending outward from one side wall of the bowwire groove 111 without extending to the other side wall. However, when the locking groove 114 penetrates the bowwire groove 111, it means that the locking groove 114 extends towards both side walls of the bowwire groove 111.

[0057] In this preferred embodiment, the locking groove 114 is located on the surface that bisects the main body 110 in the axial tilt direction, and the auxiliary groove 115 is located on one side of the locking groove 114. The locking groove 114 corresponds to the middle of the bowwire groove 111, and can lock and limit the bowwire 20 in a balanced manner.

[0058] It should be noted that the so-called surface bisecting the main body 110 in the axial tilt direction is not always the case. Orthodontic appliances, such as a set of orthodontic brackets, typically have more than 20 brackets, each corresponding to a different tooth position. The shape of the main body of each bracket varies slightly depending on the tooth position, primarily due to the axial tilt following the tooth position and the overall tilt at a certain angle. When considering the locking mechanism to balance the force on the orthodontic appliance, the locking block should be placed in the middle of the archwire groove of the orthodontic appliance, that is, at a position that roughly divides the main body 110 into two equal parts in the axial tilt direction.

[0059] Specifically, the locking groove 114 penetrates one side wall of the bow wire groove 111, thereby forming a through hole in the side wall of the bow wire groove 111; or, the locking groove 114 penetrates both one side wall and the bottom wall of the bow wire groove 111, thereby forming a notch at the bottom corner of the bow wire groove 111. Preferably, in this embodiment, the locking groove 114 penetrates both one side wall and the bottom wall of the bow wire groove 111, forming a notch 1110 at the bottom corner of the bow wire groove 111 with a height less than 1 / 2 of the bow wire groove height and a width less than 1 / 3 of the bow wire groove width.

[0060] In this preferred embodiment, the auxiliary groove 115 penetrates two opposing surfaces of the main body 110 along the gingival direction, and the auxiliary groove 115 does not penetrate the archwire groove 111. The auxiliary groove 115 is used to stably connect the locking member 200 to the main body 110. The inclination angle of the auxiliary groove 115 is consistent with the inclination angle of the base plate 130, so that the locking member 200 can enter along the inclination direction of the base plate 130 when inserted.

[0061] The locking member 200 is generally U-shaped and includes a first section 210, a second section 220, and a connecting section 230 connecting the two. The first section 210 corresponds to the locking groove 114 connecting the main body 110, and the second section 220 corresponds to the auxiliary groove 115 connecting the main body.

[0062] The first segment 210 is provided with a locking block 216. In this embodiment, preferably, the locking block 216 is located at the suspended end of the first segment 210. In other embodiments, the locking block 216 can be located in the middle or at the connecting end of the first segment 210. The first segment 210 is inserted into the locking groove 114 of the main body 110, and the locking block 216 enters the bowwire groove 111 to occupy and limit the bowwire, thereby realizing the locking function. In this embodiment, preferably, the locking block 216 is a block with a large cross-sectional dimension, that is, the cross-sectional dimension of the suspended end of the first segment 210 is larger than the cross-sectional dimension of the connecting end of the first segment 210, so that the contact area of ​​the locking block 216 is large enough to form a locking surface in the bowwire groove 111, which is sufficient to lock the bowwire 20 in the bowwire groove 111. Among them, the locking surface that can be formed on the locking block 216 includes the end face and the side face of the suspended end of the first segment 210.

[0063] Specifically, the limiting bowwire 20 is not limited to being pressed tightly against the bowwire 20; even a gap between it and the bowwire 20 can restrict the movement of the bowwire 20, thus achieving a locking effect. This is because the locking block 216, along with the first section 210, enters the bowwire groove 111 along with the locking groove 114 of the main body 110, limiting the bowwire 20. The locking block 216 occupies the internal space of the bowwire groove 111, and even with a gap between it and the bowwire 20, it reduces the movement space of the bowwire 20 within the bowwire groove 111.

[0064] The second segment 220 is provided with a bendable end 228. In this embodiment, preferably, the bendable end 228 is the suspended end of the second segment 220. In other embodiments, the bendable end 228 can be provided in the middle of the second segment 220. The second segment 220 is inserted into the auxiliary groove 115 of the main body 110. The bendable end 228 extends out of the auxiliary groove 115 from the surface of the main body 110. After being bent, the bendable end 228 engages with the main body 110, thereby stably connecting the locking member 200 to the main body 110. In this embodiment, preferably, the bendable end 228 is tail-shaped with a small cross-sectional dimension, that is, the cross-sectional dimension of the suspended end of the second segment 220 is smaller than the cross-sectional dimension of the connecting end of the second segment 220, making the bendable end 228 easy to bend and shape. After the second segment 220 is inserted into the auxiliary groove 115 from the surface of the first working wing 112, the bendable end 228 extends through the surface of the second working wing 113 and bends along the surface of the second working wing 113. Thus, the bendable end 228 clamps onto the surface of the second working wing 113, while the connecting segment 230 of the locking member 200 clamps onto the surface of the first working wing 112. That is, the locking member 200 clamps the main body 110 from two opposite sides, ensuring that the locking member 200 is securely connected to the main body 110 and does not fall off, thereby achieving a stable and continuous force exerted by the locking member 200 on the bowwire 20 in the bowwire groove 111.

[0065] When the locking function is required during orthodontic treatment, the locking element 200 is installed inside the main body 110. Specifically, the locking element 200 is inserted from the surface of the first working wing 112, wherein the first segment 210 is connected to the locking groove 114, and the second segment 220 is connected to the auxiliary groove 115. The locking block 216 of the first segment 210 enters the archwire groove 111 to lock and limit the archwire 20 inside. The bendable end 228 of the second segment 220 extends out of the auxiliary groove 115 from the surface of the second working wing 113 and bends to clamp the surface of the second working wing 113. Furthermore, the connecting section 230 of the locking member 200 clamps onto the surface of the first working wing 112. That is, the locking member 200 clamps the main body 110 from two opposite sides, ensuring that the locking member 200 is securely connected to the main body 110 and does not fall off. This ensures that the force exerted by the locking member 200 on the bowwire 20 in the bowwire groove 111 is stable and continuous. When the locking function is not needed, the entire locking member 200 can be removed from the main body 110.

[0066] In embodiment 1, the locking groove 114 is located on the surface that bisects the main body in the axial tilt direction. In other embodiments, the locking groove 114 is not provided on the surface that bisects the main body in the axial tilt direction; instead, the locking groove 114 and the auxiliary groove 115 are located on opposite sides of the surface that bisects the main body in the axial tilt direction, as shown below. Figure 12 and Figure 13 As shown.

[0067] In Embodiment 1, the locking groove 114 penetrates the archwire groove 111 only on the surface of the first working wing 112, therefore the locking member 200 is inserted into the orthodontic appliance from the side of the first working wing. In other embodiments, the locking groove 114 penetrates the archwire groove 111 on the surface of the second working wing 113, therefore the locking member 200 is inserted into the orthodontic appliance from the side of the second working wing 113, such as... Figure 14 and Figure 15 As shown.

[0068] Alternatively, in other embodiments, the locking groove 114 extends from the surface of the first working wing 112 through the bowwire groove 111 into the second working wing 113, but the locking groove 114 only forms a blind hole inside the second working wing 113 and does not connect to the surface of the second working wing 113. Similarly, in other embodiments, the locking groove 114 extends from the surface of the second working wing 113 through the bowwire groove 111 into the first working wing 112, but the locking groove 114 only forms a blind hole inside the first working wing 112 and does not connect to the surface of the first working wing 112.

[0069] Alternatively, in other embodiments, the locking groove 114 penetrates the surfaces of both the archwire groove 111 and the first working wing 112 and the second working wing 113. Therefore, the locking member 200 can be inserted from the side of the first working wing 112, or the orthodontic appliance can be inserted from the side of the second working wing 113. Figure 16-18 As shown.

[0070] Furthermore, such as Figure 16-18 As shown, the locking groove 114 is the surface of both the first working wing 112 and the second working wing 113. Correspondingly, the first segment 210 of the locking member 200 is provided with a bendable end 228, and the first segment 210 and the second segment 220 of the locking member 200 are also provided with bendable ends 228. At the same time, the clamp is attached to the surface of the second working wing 113, achieving a better and more stable connection to the main body 110. Furthermore, the second segment can also be provided with a locking block 216. Correspondingly, the auxiliary groove 115 also penetrates or extends through the bowwire groove 111. In embodiment 1, the auxiliary groove 115 does not penetrate or extend through the bowwire groove 111, and the auxiliary groove 115 does not interfere with the bowwire groove 111. However, in other embodiments, the auxiliary groove 115 can pass through or penetrate the bow wire groove 111. Under the premise that the auxiliary groove 115 passes through or penetrates the bow wire groove 111, the second segment 220 of the locking member 200 inserted into the auxiliary groove 115 can interfere with the bow wire 20 in the bow wire groove 111 or choose not to interfere, which is determined by the shape and size of the second segment 220 of the inserted locking member.

[0071] Furthermore, in Embodiment 1, the locking member 200 is used only as a locking tool. Figure 16-18 In the illustrated embodiment, a traction structure is provided on the connecting section 230 of the locking member 200, enabling the locking member of this embodiment to simultaneously perform locking and traction functions. In Embodiment 1 or other embodiments, the traction function can be achieved by providing a traction structure on the connecting end 230 without affecting the normal implementation of the original locking function.

[0072] In Embodiment 1, the main body 110 has only one locking groove 114 and one auxiliary groove 115. The locking groove 114 matches the locking block 216 of the locking member 200 to lock and limit the bowwire 20. The auxiliary groove 115 matches the bendable end 228 of the locking member to fix the locking member 200 to the main body 110. In other embodiments, the main body 110 may have at least two auxiliary grooves 115. Correspondingly, the locking member 200 includes two second segments 220, each corresponding to one of the two auxiliary grooves 115. Preferably, the two auxiliary grooves 115 are symmetrically distributed on both sides of the locking groove 114 to fix the locking member 200 to the main body 110 in a balanced manner. Similarly, in other embodiments, the main body 110 may be provided with at least two locking grooves 114. Correspondingly, the locking member 200 includes two first segments 210. Preferably, the two locking grooves 114 are symmetrically distributed to lock the bowwire 20 in a balanced manner.

[0073] Compared with the prior art, this embodiment provides two grooves on the orthodontic appliance—a locking groove and an auxiliary groove—corresponding to the locking function and the function of stable connection to the main body, respectively. This ensures the locking function and allows the locking component to be stably fixed to the main body, thereby improving the overall functional level of the locking component.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
