Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to an orthodontic appliance and orthodontic system with traction and locking function. Background Technology

[0002] During orthodontic treatment, traction hooks are typically used to gradually move a portion of the teeth to the correct position. The ideal orthodontic process is as follows: A first orthodontic appliance with a first traction hook is fixed to the surface of the first tooth, which does not need to be moved. A second orthodontic appliance with a second traction hook is fixed to the surface of the second tooth, which needs to be moved to the correct position. Then, a rubber band is placed on the first and second traction hooks. The elastic force of the rubber band is transmitted to the first and second orthodontic appliances to pull the second tooth to the correct position.

[0003] However, when using traditional orthodontic appliances for correction, at least the following two problems exist:

[0004] 1. The archwire is placed in the archwire slot of the orthodontic appliance. During traction, due to the elastic force of the rubber band, the elastic force is transmitted to the second orthodontic appliance through the second traction hook, forcing the second orthodontic appliance to move the second tooth. At the same time, the elastic force is also transmitted to the first orthodontic appliance through the first traction hook, causing the first orthodontic appliance to also move relative to the archwire, thus affecting the correction effect and prolonging the treatment time.

[0005] 2. Traction hooks are usually formed on the body of orthodontic appliances by welding, bonding or integral molding. When the traction function is not needed, the traction hook protrudes from the body, which can easily cause a foreign body sensation and may also scratch the inner lip lining, causing ulcers. Utility Model Content

[0006] Therefore, it is necessary to provide an orthodontic appliance and orthodontic system with traction locking function that can lock the archwire and is detachable when not in use, in order to address the above-mentioned technical problems.

[0007] An orthodontic appliance with traction locking function includes a main body and a cover. The main body has an archwire groove that runs through it along the mesiodistal direction, dividing the main body into a first working wing and a second working wing. The cover is movably disposed on the second working wing and can open or close the archwire groove. The main body also has an assembly groove for detachably assembling a traction member. The traction member includes a traction section, a connecting section, and an adapter section connected in sequence. The adapter section is adapted to the main body. The connecting section is at least partially located within the assembly groove. A locking part protrudes from the connecting section and corresponds to the archwire groove to directly or indirectly limit the archwire.

[0008] In one embodiment, the mounting groove is connected to the archwire groove, the mounting groove extends along the gingival-maxillary direction, and may or may not penetrate the main body.

[0009] In one embodiment, the locking portion includes at least one protrusion for abutting or directly limiting the bowwire.

[0010] In one embodiment, the assembly groove is connected to the bowwire groove, the assembly groove extends in a mesiodistal direction, and may or may not penetrate the main body.

[0011] In one embodiment, a locking member is also included, which is located at the connection between the assembly groove and the bow wire groove. The locking part is linked with the locking member to limit the bow wire, thereby realizing that the locking part is used to indirectly limit the bow wire.

[0012] In one embodiment, the traction member is rotatable relative to the mounting groove, and the locking portion includes at least one protrusion for abutting or directly limiting the bowwire.

[0013] In one embodiment, the locking portion is provided with a through hole to allow the locking portion to expand or contract radially.

[0014] In one embodiment, the locking part includes at least two clamping arms spaced apart from each other for clamping the bowwire.

[0015] In one embodiment, the assembly groove is not connected to the bow wire groove, and a locking groove is also provided on the main body. The locking groove is connected to the bow wire groove, and the locking part is located in the locking groove and directly or indirectly limits the bow wire.

[0016] In one embodiment, the adapter segment can be bent after passing through the mounting slot; or

[0017] The adapter section is provided with external threads, and the second working wing is provided with an adapter groove that communicates with the bowwire groove. The adapter groove is provided with internal threads, and the adapter section and the adapter groove are engaged by threaded connection; or

[0018] The adapter section is snapped onto the second working wing using a snap-fit ​​method.

[0019] In one embodiment, at least one of the following features is also included:

[0020] The traction section protrudes from the assembly slot;

[0021] The traction section includes an integrally formed rod and a ball cap. One end of the rod is connected to the connecting section, and the other end of the rod is suspended and connected to the ball cap.

[0022] The traction section, the connecting section, and the adapter section are integrally formed;

[0023] The assembly groove includes a large-diameter section and a small-diameter section connected in sequence;

[0024] The assembly groove is at least partially connected to the bottom wall of the bowwire groove;

[0025] The connecting section is also provided with a limiting part at one end near the traction section. The limiting part is used to abut against the first working wing to prevent the traction member from excessively extending into the assembly groove.

[0026] An orthodontic system includes at least one orthodontic appliance and traction element having a traction locking function as described in any of the preceding claims, the traction element being detachably mounted in a mounting slot.

[0027] The above-mentioned orthodontic appliances with traction locking function have at least the following advantages:

[0028] During orthodontic treatment, when traction is required, the traction device is installed in the mounting slot. After assembly, the adapter section fits into the main body to fix the traction device to the main body. At this time, the connecting section is at least partially located in the mounting slot, and the traction section protrudes from the main body to achieve the traction function. The locking part protruding on the connecting section directly or indirectly limits the archwire, preventing the archwire from moving relative to the archwire slot. Therefore, during traction, the elastic force of the rubber band is transmitted to the second orthodontic appliance through the second traction hook, forcing the second orthodontic appliance to move the second tooth. At the same time, the elastic force is also transmitted to the first orthodontic appliance through the first traction hook, but because the locking part directly or indirectly limits the archwire, the first orthodontic appliance will not move relative to the archwire or will move very little, thus improving the orthodontic efficiency. When traction is not needed, the entire traction device can be removed from the mounting slot. Attached Figure Description

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] Please see Figures 1 to 7 The orthodontic system 10 in the first embodiment includes at least one orthodontic appliance 100 (hereinafter also referred to as orthodontic appliance 100) with traction and locking function and a traction member 200, wherein the traction member 200 is detachably installed on the orthodontic appliance 100 to enable the orthodontic appliance 100 to have the traction and locking function. The following description uses an orthodontic bracket as an example to illustrate the orthodontic appliance 100. Specifically, the orthodontic appliance 100 with traction and locking function 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 can also be a buccal tube.

[0057] Furthermore, the main body 110 is provided with an archwire groove 111, which runs through the main body 110 in a mesiodistal direction. 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. The archwire groove 111 is mainly used to hold the archwire 20. The archwire 20 transmits torque to the orthodontic appliance 100, and then through the orthodontic appliance 100, it transmits the torque to the teeth, causing the teeth to slowly move to the correct position.

[0058] The main body 110 is also provided with an assembly groove 140, which is connected to the bow wire groove 111. The assembly groove 140 is used to detachably mount the traction member 200. Specifically, the assembly groove 140 is at least partially connected to the bottom wall of the bow wire groove 111, and the height of the top of the assembly groove 140 is equal to or greater than the bottom wall of the bow wire groove 111. Therefore, after the traction member 200 is mounted in the assembly groove 140, it can limit or abut the bow wire 20 to achieve the purpose of locking.

[0059] The traction component 200 includes a traction section 210, a connecting section 220, and an adapter section 230 connected sequentially. The adapter section 230 is adapted to the main body 110. In this embodiment, the traction section 210, connecting section 220, and adapter section 230 are integrally formed, which is simple to manufacture and ensures strength. Specifically, the traction section 210 protrudes from the mounting groove 140, thus the traction section 210 is used for the traction attachment to be fitted, and plays a traction function. The traction section 210 includes an integrally formed rod body 211 and a ball cap body 212. One end of the rod body 211 is connected to the connecting section 220, and the other end of the rod body 211 is suspended and connected to the ball cap body 212. The rod body 211 is mainly used for the traction attachment to be fitted, and the ball cap body 212 is mainly used to prevent the traction attachment fitted on the rod body 211 from falling off. The number of ball cap bodies 212 can be at least one, for example, one, two, or more.

[0060] The adapter segment 230 is adapted to the main body 110 to mount the traction member 200 onto the main body 110. Specifically, in this embodiment, the adapter segment 230 is adapted to the second working wing 113, and the adapter segment 230 can bend after passing through the mounting groove 140. Correspondingly, the mounting groove 140 extends along the gingival direction and penetrates the main body 110, and the adapter segment 230 bends after passing through the mounting groove 140, such as... Figure 2 As shown. Of course, in other embodiments, the assembly groove 140 may also extend along the proximal-distal direction and penetrate the main body 110, and the adapter section 230 may bend along the direction close to the first working wing 112 or close to the second working wing 113 after passing through the assembly groove 140.

[0061] Alternatively, in other embodiments, the adapter segment 230 is not bent, but is installed into the assembly groove 140 by means of threads. In this case, the assembly groove 140 may or may not penetrate the main body 110. Specifically, the adapter segment 230 is provided with external threads, and the second working wing 113 is provided with an adapter groove that communicates with the bowwire groove 111. The adapter groove is provided with internal threads, and the adapter segment 230 and the adapter groove are engaged by means of threads. Alternatively, the adapter segment 230 is snapped onto the second working wing 113 by means of a snap-fit ​​mechanism.

[0062] Please see Figure 3 , 6 In specific embodiment 7, the connecting section 220 near the traction section 210 is further provided with a limiting part 221. The limiting part 221 is used to abut against the first working wing 112 to prevent the traction member 200 from excessively extending into the assembly groove 140. Specifically, the width of the limiting part 221 is larger than the width of the assembly groove 140. By providing the limiting part 221, the traction member 200 can be prevented from excessively extending into the assembly groove 140 and losing its traction function.

[0063] Furthermore, the connecting section 220 is at least partially located within the assembly groove 140, and a locking part 222 protrudes from the connecting section 220. The locking part 222 corresponds to the bow wire groove 111 to directly or indirectly limit the bow wire 20. Specifically, limiting the bow wire 20 includes, but is not limited to, pressing against the bow wire 20, having a clearance between the bow wire 20 and the bow wire 20 to restrict the movement of the bow wire 20.

[0064] Please see Figures 3 to 7 Specifically, the locking part 222 includes at least one protrusion, which is used to abut or directly limit the bowwire 20. The protrusion protrudes from the outer side of the connecting part, and after the protrusion enters the mounting groove 140, the height of the protrusion interferes with the bowwire 20, thereby jointly abutting the bowwire 20 along the jaw direction through the side 223 of the protrusion and the side wall and bottom wall of the bowwire groove 111, preventing the bowwire 20 from moving. Correspondingly, the mounting groove 140 includes a large-diameter section and a small-diameter section connected in sequence. The large-diameter section is located on the first working wing 112 and accommodates the connecting section 220 and the locking part 222, while the small-diameter section is located on the second working wing 113 and accommodates the adapter section 230 and part of the connecting section 220.

[0065] Of course, in other embodiments, the archwire 20 can also be prevented from moving by the side surface 223 of the protrusion and the side and bottom walls of the archwire groove 111 together pressing against the archwire 20 along the gum line. Alternatively, the archwire 20 can be prevented from moving by the side surface 223 and / or top surface of the protrusion together pressing against the side and / or bottom walls of the archwire groove 111 and the bottom surface of the cover portion 120.

[0066] Please see Figure 8 and 9In the second embodiment, the differences from the first embodiment include, but are not limited to, the fact that the bowwire 20 is abutted against by the top surface 224 of the protrusion and the side and bottom walls of the bowwire groove 111. The top surface 224 of the protrusion is an inclined surface, and the height of the inclined surface gradually decreases along the direction close to the second working wing 113. Therefore, the relative position of the traction member 200 and the bowwire 20 can be adjusted by fine-tuning to better lock bowwires 20 of different sizes. Alternatively, in other embodiments, the top surface 224 of the protrusion is a flat surface, and the bowwire 20 is abutted against by the top surface 224 of the protrusion and the bottom surface of the cover portion 120. Alternatively, in other embodiments, the top surface 224 of the protrusion is an inclined surface, and the height of the inclined surface gradually decreases along the direction close to the first working wing 112.

[0067] Please see Figure 10 and 11 In the third embodiment, the differences from the first embodiment include, but are not limited to, the traction member 200 indirectly limiting the archwire 20. Specifically, the orthodontic system 10 also includes a locking member 240, located at the connection between the mounting groove 140 and the archwire groove 111. The locking part 222, in conjunction with the locking member 240, limits the archwire 20, thereby achieving indirect limiting of the archwire 20 by the locking part 222. Specifically, the locking member 240 includes a linkage part 241 and a locking plate 242 that are interconnected or integrally formed. The linkage part 241 is linked with the locking part 222. The locking plate 242 is located in the archwire groove 111. By linking the linkage part 241 with the locking part 222, the linkage part 241 can drive the locking plate 242 to move, thereby achieving the purpose of indirectly locking the archwire 20 by the locking part 222. The contact area between the locking plate 242 and the archwire 20 is larger, which can better ensure the locking effect.

[0068] Please see Figures 12 to 15 In the fourth embodiment, the differences from the first embodiment include, but are not limited to, the locking part 222 of the fourth embodiment includes at least two clamping arms 250 arranged at intervals opposite to each other, the clamping arms 250 being used to clamp the bowwire 20. Specifically, when the traction member 200 is installed into the mounting groove 140, the clamping arms 250 are also located in the bowwire groove 111, the clamping arms 250 have a certain elasticity, and the bowwire 20 is clamped in the clamping arms 250 at the same time as it is inserted into the bowwire groove 111.

[0069] Please see Figures 16 to 18 In the fifth embodiment, the differences from the first embodiment include, but are not limited to, the traction member 200 of the fifth embodiment being rotatable relative to the mounting groove 140, and the locking part 222 including at least one protrusion for abutting or directly limiting the bow wire 20. When it is necessary to abut or limit the bow wire 20, the traction member 200 is rotated, thereby causing the protrusion to rotate to a position where it can abut or limit the bow wire 20.

[0070] In other embodiments, the locking part 222 is provided with a through hole to allow the locking part 222 to expand or contract radially, thereby generating an elastic force in the locking part 222 to elastically limit the bowwire 20.

[0071] Of course, in other embodiments, the mounting groove may not be connected to the bowwire groove. Instead, a locking groove is formed on the main body, which is connected to the bowwire groove. The locking part is located in the locking groove and directly or indirectly limits the bowwire. For example, the locking groove is formed on the first working wing, and the locking part passes through the locking groove and directly or indirectly limits the bowwire. Alternatively, the locking groove is formed on the second working wing, and the locking part passes through the locking groove and directly or indirectly limits the bowwire.

[0072] The above-mentioned orthodontic system 10 has at least the following advantages:

[0073] During orthodontic treatment, when traction is required, the traction component 200 is installed in the mounting slot 140. After assembly, the adapter section 230 is fitted to the main body 110 to fix the traction component 200 on the main body 110. At this time, the connecting section 220 is at least partially located in the mounting slot 140, and the traction section 210 protrudes outward from the main body 110 to achieve the traction function. The locking part 222 protruding on the connecting section 220 directly or indirectly limits the archwire 20, preventing the archwire 20 from moving relative to the archwire slot 111. Therefore, during traction, the elastic force of the rubber band is transmitted to the second orthodontic appliance 100 through the second traction hook, forcing the second orthodontic appliance 100 to move the second tooth. At the same time, the elastic force is also transmitted to the first orthodontic appliance 100 through the first traction hook. However, since the locking part 222 directly or indirectly limits the archwire 20, the first orthodontic appliance 100 will not move relative to the archwire 20 or will move only a small distance, thus improving the orthodontic efficiency. When the traction function is not needed, the entire traction component 200 can be removed from the assembly slot 140.

[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.
