Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to an archwire end protection device for oral orthodontics. Background Art

[0002] Orthodontic archwire is a medical device used in orthodontic surgery. The correction force exerted by the orthodontic archwire guides the teeth to make them straight. Since orthodontic archwires are generally hard metal archwires, such as stainless steel archwires or nickel-titanium alloy archwires, the ends of the archwires usually need to be processed after installation to avoid damage to the oral cavity. At present, the common treatment methods are to bend the end of the arch wire back or to wrap the end of the arch wire with a silicone sleeve. However, the treatment method of bending the end of the arch wire back is difficult to operate and time-consuming, and it is difficult for some alloy arch wires to be bent back or the arch wire is damaged and the length changes during the bending process, which affects the correction force of the arch wire and thus affects the orthodontic treatment effect. For the method including the silicone sleeve, on the one hand, the silicone sleeve cannot be stably fixed and is very easy to fall off after long-term wearing. On the other hand, the silicone sleeve cannot fix the end of the arch wire. In addition, the existing arch wire end generally uses a metal band fixed on the tooth to fix the end of the orthodontic arch wire. Since the metal band needs to surround the tooth and be put on the tooth to fix the bracket and the end of the arch wire, the operation steps are complicated and it is very easy to cause discomfort when wearing.

[0003] Therefore, it is necessary to design a protective device that can provide continuous protection to the oral cavity and effectively fix the end of the arch wire. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the present invention, the present invention is now further described in conjunction with specific implementation methods.

[0034] Embodiment 1:

[0035] like Figure 1~Figure 5 As shown, the utility model provides an archwire end protection device for oral orthodontics, which includes a detachably connected bracket 1 and a protective sleeve 2. It should be noted that the archwire 3 is a mature prior art, and its specific structure and material are not described here. The archwire 3 can be round wire or square wire. This embodiment is described by taking square wire as an example.

[0036] like Figure 2 As shown, the dental bracket 1 comprises a slot seat 11 and a slot frame 12 arranged above the slot seat 11, a bonding surface 111 for adhering to the tooth surface is arranged at the bottom of the slot seat 11, and two slot frames 12 are arranged in parallel and spaced apart. The slot frame 12 is provided with a groove 121 adapted to the archwire 3, and frame wings 122 symmetrically arranged on both sides of the groove 121, wherein a ligation groove 123 arranged opposite to the slot seat 11 is arranged at the bottom of the frame wing 122, and the ligation groove 123 is arranged in parallel with the groove 121.

[0037] Optionally, in some embodiments, the slot frame 12 is connected to the slot seat 11 in an integrated structure.

[0038] like Figure 1 , Figure 3 As shown, the protective sleeve 2 includes a main body 21 that abuts against the outer side of the slot frame 12 at one end of the bracket slot 1, and a cover portion 22 that covers the bracket slot 1. The cover portion 22 is located directly above the groove 121 and the two side wings 122. Figure 4As shown, the main body 21 is provided with a locking groove 211 adapted to the arch wire 3, and the locking groove 211 is arranged relatively parallel to the groove 121, so that the end of the arch wire 3 fixed in the groove 121 can be inserted into the locking groove 211. The upper end surface of the covering part 22 is a smooth arc surface to avoid damage to the mucosa inside the oral cavity.

[0039] Optionally, in some embodiments, the main body 21 and the cover 22 are connected in an integrated structure.

[0040] like Figure 4 As shown, the main body 21 is provided with guide blocks 23 symmetrically distributed on both sides of the locking groove 211, and the guide blocks 23 include a baffle 231 and an insert block 232 connected to each other. Figure 1 As shown, the baffle 231 is arranged relative to the outer side of the frame wing 122 of the slot frame 12 so as to abut against the outer side of the frame wing 122 of the slot frame 12, and the insert block 232 is adapted to the ligation groove 123 of the frame wing 122 so as to extend into the ligation groove 123 at the bottom of the frame wing 122 and abut against it.

[0041] Optionally, in some embodiments, the guide block 23 is connected to the main body 21 in an integrated structure, and the baffle 231 is connected to the insert block 232 in an integrated structure.

[0042] like Figure 3 , Figure 4 As shown, the cover portion 22 is provided with limit blocks 221 symmetrically distributed on both sides of the locking groove 211, and the limit blocks 221 are movably hinged to the cover portion 22 so that the limit blocks 221 can be completely embedded in the gap between the adjacent slot frames 12 of the dental bracket slot 1 to play a limiting role (refer to Figure 1 ), or completely detach from the adjacent slot frame 12 to install or remove the protective cover 2 (reference Figure 5 When the limiting block 221 is completely embedded in the gap between the adjacent slot frames 12, the two sides of the limiting block 221 are respectively in contact with the slot frames 12 on both sides, thereby playing a role of lateral limiting.

[0043] Embodiment 2:

[0044] For Example 2 of the utility model, Figure 6 , Figure 7 Note that description of parts that are not different from those in Embodiment 1 will be omitted and will be given the same reference numerals.

[0045] like Figure 6 , Figure 7As shown, the utility model relates to an archwire end protection device for oral orthodontics, wherein the main body 21 is also provided with an adjustment component 24 movably embedded in the locking groove 211, and the adjustment component 24 includes an outer plate 241 adapted to the locking groove 211, an inner plate 243 movably embedded in the locking groove 211, a spring 242 located between the inner plate 243 and the outer plate 241, and a bolt 244 threadedly connected to the inner plate 243.

[0046] The outer plate 241 abuts against the end of the arch wire 3 inserted into the locking groove 211, and the two ends of the spring 242 abut against the outer plate 241 and the inner plate 243 respectively, thereby playing a clamping role on the arch wire 3. On the one hand, it can cover the end of the arch wire 3 to prevent it from causing damage to the oral cavity and play a protective role. On the other hand, it can fix the end of the arch wire 3 to prevent the end of the arch wire 3 from deviating, sliding out, or even detaching from the bracket 1, especially when the arch wire 3 becomes loose after wearing for a long time. In addition, the movable outer plate 241 connected to the spring 242 can adapt to arch wires 3 with different lengths at the end, improve practicality and expand the scope of application. At the same time, it can effectively maintain the correction force at the end of the arch wire 3, reduce the sliding phenomenon of the arch wire 3 caused by the loosening of the end of the arch wire 3, and reduce the problem of poor orthodontic treatment effect.

[0047] The bolt 244 rotatably passes through the main body 21 of the protective sleeve 2. By rotating the bolt 244, the distance between the inner plate 243 and the bottom of the locking groove 211 can be adjusted to adjust the deformation stroke of the spring 242, thereby changing the force of the outer plate 241 on the arch wire 3 to make it match the force generated by the arch wire 3 itself, thereby improving the orthodontic correction effect of the arch wire 3; at the same time, even if the arch wire 3 becomes loose after being worn for a long time, it will not fall off accidentally.

[0048] Specifically, the inner plate 243 is provided with a threaded hole compatible with the bolt 244, and the main body 21 of the protective sleeve 2 is provided with a countersunk locking hole compatible with the bolt 244. The bolt 244 can only be rotatably embedded in the countersunk locking hole and cannot move along the direction of the locking groove 211. By rotating the bolt 244, the inner plate 243 threadably connected to the bolt 244 moves along the direction of the locking groove 211.

[0049] Optionally, in some embodiments, the bolt 244 is rotatably connected to the inner plate 243, and the main body 21 of the protective sleeve 2 is provided with a threaded hole adapted to the bolt 244. The inner plate 243 is driven away from or close to the bottom of the locking groove 211 by rotating the bolt 244. At this time, the bolt 244 and the inner plate 243 move synchronously.

[0050] To sum up, the arch wire end protection device for oral orthodontics provided by the utility model can replace the silicone sleeve or metal band ring set at the end of the arch wire in the prior art, so as to prevent the arch wire end from causing damage to the oral cavity, and at the same time effectively fix the arch wire end, thereby avoiding the arch wire slipping out and falling off caused by loosening or deviation of the arch wire end, thereby improving the oral orthodontic correction effect.

[0051] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
