Abstract
Description
Technical Field
[0001] This application relates to the technical field of orthodontic appliances, and in particular to a closed-loop oblique guide brace. Background Technology
[0002] Current orthodontic appliances typically include flat guides and inclined guides. Flat guides are suitable for patients with deep overbite (anterior teeth covering more than 1 / 3 of the jaw). By covering the occlusal surface of the maxillary anterior teeth, the flat guide prevents direct contact between the upper and lower anterior teeth, forcing the mandibular posterior teeth to gradually elongate, thereby increasing the vertical height of the posterior teeth, opening the bite, and reducing anterior overbite. Inclined guides are suitable for patients with functional crossbite. The inclined guide, through its inclined surface design, guides the mandible to slide forward when the mandible is closed, causing the mandibular anterior teeth to gradually retract and the maxillary anterior teeth to gradually protrude, thus correcting the crossbite relationship.
[0003] However, in the existing technology, both planar and inclined guide plates have a technical problem: some patients will unconsciously open their mouths when they are in a deep sleep at night, which makes it impossible for the orthodontic appliance to correct the patient normally. Therefore, this application proposes a closed-knot inclined guide aligner. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a closed-loop oblique brace to solve the technical problem that the braces are less effective when used by patients at night.
[0005] The above-mentioned objective of this application is achieved through the following technical solution: a locking type oblique guide aligner, including an upper aligner, a lower aligner, an upper locking structure, and a lower locking structure, wherein the upper locking structure is disposed on the upper aligner, and the lower locking structure is disposed on the lower aligner. In use, the upper locking structure and the lower locking structure cooperate to lock the upper aligner and the lower aligner closed.
[0006] Furthermore, the upper locking structure is a locking protrusion, one end of which is fixedly connected to the inner arc surface of the upper brace, and the other end of which extends beyond the occlusal surface of the upper brace and has a locking groove. The opening of the locking groove is located on the side surface of the locking protrusion near the outer arc surface of the upper brace. The lower locking structure is a locking block, which is fixedly installed on the inner arc surface of the lower brace. In use, the locking block and the locking groove cooperate to lock the upper and lower braces together.
[0007] By adopting the above technical solution, after medical staff make the upper and lower braces according to the patient's dental mold, they install locking protrusions on the upper braces by heat fusion and make locking grooves on the locking protrusions. Then, they install the locking blocks on the lower braces by heat fusion. Before going to sleep at night, the patient puts the upper braces on the upper teeth and then the lower braces on the lower teeth. The patient then moves the lower teeth forward so that the locking blocks are misaligned with the locking protrusions. Then, the patient closes their mouth so that the end of the locking block away from the lower brace is aligned with the opening of the locking groove. Then, the patient slightly retracts the lower teeth so that the locking block is inserted into the locking groove, thus locking the upper and lower braces together. This achieves the purpose of correcting the patient's functional malocclusion, thereby solving the technical problem of low effectiveness of the braces when the patient uses them at night in the existing technology. When the patient needs to remove the braces, they only need to move the lower teeth forward again to disengage the locking blocks from the locking protrusions.
[0008] Furthermore, the locking block has an inclined surface on the side near the locking protrusion, which is used to assist the patient in closing the upper and lower braces.
[0009] While the above-mentioned technical solutions address the issue of reduced effectiveness of the upper and lower locking structures when patients use braces at night, patients sometimes forget to move their upper or lower teeth forward after putting on the braces. This causes the locking blocks to collide with the locking protrusions when the patient closes the braces, generating a counter-vibration force and affecting the patient's experience. The inclined surface design solves this problem. When the patient closes the braces and forgets to move their upper or lower teeth forward, the locking protrusions contact the inclined surface of the locking blocks. As the patient exerts force when closing the braces, the locking protrusions press against the inclined surface and push the locking blocks forward along the inclined surface. This guides the patient to move their upper or lower teeth forward, preventing the locking blocks and locking protrusions from colliding and generating a counter-vibration force, thus improving the patient's experience.
[0010] Furthermore, the locking block has an arc surface on the side away from the locking protrusion, which is used to assist the patient in opening the upper and lower braces.
[0011] While the above-mentioned technical solutions address the issue of reduced effectiveness of the upper and lower locking structures when patients use braces at night, patients may forget to move their upper or lower teeth forward when opening the braces, hindering the opening process and affecting their experience. The curved surface design solves this problem. When a patient forgets to move their upper or lower teeth forward, the curved surface of the locking block contacts the bottom surface of the locking groove. As the patient applies force, the curved surface of the locking block gradually moves forward, guiding the patient to move their upper or lower teeth forward. This prevents obstruction when opening the braces and improves the patient's experience.
[0012] Furthermore, an arc portion is provided at the connection between the arc surface and the inclined surface.
[0013] By adopting the above technical solution, a sharp end is prevented from forming at the connection between the arc surface and the inclined surface, thereby preventing the connection between the arc surface and the inclined surface from piercing the patient's oral cavity skin, and further improving the patient's user experience.
[0014] In one embodiment, the upper locking structure includes a locking bevel block, which is fixedly disposed on the inner arc surface of the upper brace. The lower locking structure includes a locking recess and a locking groove. The locking recess is fixedly disposed on the inner arc surface of the lower brace. The locking groove is inclinedly opened inside the locking recess, and its opening is located on the side of the locking recess opposite to the locking bevel block. The locking bevel block is adapted to the locking groove, and the locking groove is used to guide the locking bevel block to move the upper brace forward.
[0015] By adopting the above technical solution, firstly, dental molds of the upper and lower teeth are made according to the patient's tooth shape. Then, a locking bevel is installed on the inner arc surface of the upper tooth mold, and a locking recess is installed on the inner arc surface of the lower tooth mold. Finally, upper and lower dental crowns with upper and lower locking structures are cast using the dental molds of the upper and lower teeth. Before going to sleep at night, the patient puts the upper braces on their upper teeth and the lower braces on their lower teeth. Then, the patient closes their mouth. During this process, the locking blocks on the upper braces are gradually inserted into the locking slots. As the locking slots guide the locking blocks, they move the upper braces forward, causing the patient's upper teeth to move forward as well, thus correcting the deep overbite. Because of the inclined design of the locking slots, it takes a greater force for the locking blocks to disengage from the slots. This increases the resistance when the patient opens their mouth, reducing the likelihood of the patient's mouth involuntarily opening while in deep sleep at night. This achieves the goal of solving the technical problem of lower effectiveness of orthodontic appliances when used at night in existing technologies.
[0016] Furthermore, the upper brace, lower brace, upper locking structure, and lower locking structure are all made of medical-grade transparent plastic.
[0017] By adopting the above technical solutions, the upper and lower braces, upper and lower locking structures made of medical transparent plastic have a visual effect, allowing medical staff to observe the orthodontic effect of the upper and lower braces combined with the upper and lower locking structures. They also enhance patient comfort and safety, are lightweight, biocompatible, and resistant to pollution; they are also resistant to chemical corrosion and impact.
[0018] In one embodiment, the upper locking structure includes a locking magnet assembly, which includes two locking magnets, which are respectively fixedly disposed on both sides of the outer arc surface of the upper brace. The lower locking structure includes an attraction magnet assembly, which includes two attraction magnets, which are respectively fixedly disposed on both sides of the outer arc surface of the lower brace. The two attraction magnets are used to attract the two locking magnets one-to-one, so that the locking magnets drive the upper brace forward.
[0019] By adopting the above technical solution, medical staff create upper and lower braces based on the patient's dental mold. Then, locking magnets are installed on the upper braces, and attracting magnets are installed on the lower braces. Before going to sleep at night, the patient puts the upper braces on their upper teeth and the lower braces on their lower teeth. The patient then closes their mouth. At this time, the attracting magnets are located on the side of the locking magnets closest to the patient's lips and attract the locking magnets. The locking magnets are moved forward by the attracting magnets, causing the upper braces to move forward with them, thus correcting the patient's functional malocclusion. Furthermore, the attraction of the magnets to the locking magnets greatly increases the resistance for the patient to open the braces, thereby solving the technical problem of lower effectiveness when patients use orthodontic appliances at night in existing technologies.
[0020] Furthermore, the upper and lower braces are provided with multiple mounting structures for installing the upper locking structure and the lower locking structure, and each of the multiple mounting structures corresponds to a locking magnet or an attracting magnet. The locking magnet and the attracting magnet are both mounted on the braces through the mounting structures.
[0021] Furthermore, the mounting structure includes mounting holes formed on the braces and fixing parts inserted into the mounting holes, and the fixing parts in the plurality of mounting structures are respectively fixedly connected to locking magnets or attracting magnets.
[0022] By adopting the above technical solution, before installing the attraction magnet assembly on the lower brace, the two attraction magnets must first be fixedly installed on the two fixing parts one by one. Then, the other ends of the two fixing parts are inserted into the mounting holes of the lower brace one by one. Finally, the fixing parts are fixed in the mounting holes to complete the installation of the attraction magnet assembly. Similarly, before installing the locking magnet on the upper brace, the two locking magnets must first be fixedly installed on the two fixing parts one by one. Then, the other ends of the fixing parts are inserted into the mounting holes of the upper brace one by one. Finally, the fixing parts are fixed in the mounting holes to complete the installation of the locking magnet assembly.
[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a locking structure, after medical staff create upper and lower braces based on the patient's dental impression, they install locking protrusions on the upper braces using a heat-fusion method, and create locking grooves on the locking protrusions. Then, they install the locking blocks on the lower braces using a heat-fusion method. Before going to sleep at night, the patient puts the upper braces on their upper teeth and then the lower braces on their lower teeth. The patient then moves their lower teeth forward, causing the locking blocks to shift away from the locking protrusions. Then, the patient closes their mouth, so that the end of the locking block facing away from the lower brace is aligned with the opening of the locking groove. The patient then slightly retracts their lower teeth, allowing the locking block to insert into the locking groove, thus locking the upper and lower braces together. This achieves the purpose of correcting the patient's functional malocclusion, thereby solving the technical problem of low effectiveness of the orthodontic appliances when the patient uses them at night in existing technologies.
[0024] 2. Through the locking structure, the patient puts the upper braces on the upper teeth and the lower braces on the lower teeth before going to sleep at night. Then the patient closes their mouth. During this process, the locking blocks on the upper braces gradually insert into the locking grooves. As the locking grooves guide the locking blocks, the locking blocks move the upper braces forward, causing the patient's upper teeth to move forward as well, thereby correcting the deep overbite. Furthermore, because the locking grooves are tilted, it takes a greater force for the locking blocks to disengage from the locking grooves. This increases the resistance when the patient opens their mouth, thus reducing the possibility that the patient's mouth will involuntarily open while in deep sleep at night. This achieves the goal of solving the technical problem of the low effectiveness of orthodontic appliances when patients use them at night in existing technologies.
[0025] 3. Through the locking structure, after medical staff create the upper and lower braces based on the patient's dental impression, they then install locking magnets on the upper braces and attracting magnets on the lower braces. Before going to sleep at night, the patient puts the upper braces on their upper teeth and the lower braces on their lower teeth. The patient then closes their mouth. At this time, the attracting magnets are located on the side of the locking magnets closest to the patient's lips and attract the locking magnets. The locking magnets are moved forward by the attracting magnets, causing the upper braces to move forward with the locking magnets, thus correcting the patient's functional malocclusion. Furthermore, the attraction magnets, after attracting the locking magnets, greatly increase the resistance for the patient to open the braces, thereby solving the technical problem of low effectiveness when patients use orthodontic appliances at night in existing technologies.

Detailed Implementation
[0028] The present application will be further described in detail below with reference to the accompanying drawings.
[0029] Example 1, referring to Figure 1 , Figure 2 A locking type oblique guide aligner includes an upper aligner 10, a lower aligner 11, an upper locking structure, and a lower locking structure. The upper locking structure is disposed on the upper aligner 10, and the lower locking structure is disposed on the lower aligner 11. In use, the upper locking structure and the lower locking structure cooperate to lock the upper aligner 10 and the lower aligner 11 closed. The upper locking structure is a locking protrusion 200. One end of the locking protrusion 200 is fixedly connected to the inner arc surface of the upper aligner 10, and the other end of the locking protrusion 200 extends beyond the occlusal surface of the upper aligner 10 and has a locking groove 202. The opening of the locking groove 202 is located on the side surface of the locking protrusion 200 near the outer arc surface of the upper aligner 10. The lower locking structure is a locking block 201. The locking block 201 is fixedly installed on the inner arc surface of the lower aligner 11. In use, the locking block 201 and the locking groove 202 cooperate to lock the upper aligner 10 and the lower aligner 11 closed.
[0030] Both the upper brace 10 and the lower brace 11 can be manufactured using casting, injection molding, or 3D printing. The locking protrusion 200 and locking block 201 can be integrated, heat-fused, or installed on the brace 1 using other fixing methods. Regarding the occlusal surface of the upper brace 10, it is the side opposite to the lower brace 11 when worn on the patient's teeth. Similarly, the end face of the lower brace 11 is the side opposite to the upper brace 10 when worn on the patient's teeth. Regarding the inner curved surface of the upper brace 10, it is the side facing away from the patient's lips when worn; correspondingly, the side closer to the patient's lips is the outer curved surface. Regarding the inner curved surface of the lower brace 11, it is the side facing away from the patient's lips when worn; correspondingly, the side closer to the patient's lips is the outer curved surface.
[0031] For example, after medical staff make the upper brace 10 and lower brace 11 based on the patient's dental impression, they install a locking protrusion 200 on the upper brace 10 by heat fusion and create a locking groove 202 on the locking protrusion 200. Then, they install a locking block 201 on the lower brace 11 by heat fusion. Before going to sleep at night, the patient puts the upper brace 10 on the upper teeth and then puts the lower brace 11 on the lower teeth. The patient then moves the lower teeth forward, causing the locking block 201 to shift away from the locking protrusion 200, and then closes the mouth. The upper lip is moved so that the end of the locking block 201 facing away from the lower brace 11 is aligned with the opening of the locking slot 202. Then, the patient slightly retracts the lower teeth so that the locking block 201 is inserted into the locking slot 202, thereby locking the upper brace 10 and the lower brace 11 together. This achieves the purpose of correcting the patient's functional malocclusion, thus solving the technical problem of low effectiveness of the orthodontic appliance when used at night in the existing technology. When the patient needs to remove the brace 1, he / she only needs to move the lower teeth forward again so that the locking block 201 disengages from the locking protrusion 200.
[0032] It should be noted that if the patient has a deep overbite, the locking protrusion 200 can be placed on the inner arc surface of the lower brace 11, and the locking block 201 can be placed on the inner arc surface of the upper brace 10. In this case, when the patient uses the device, he / she needs to move his / her upper teeth forward and then close his / her mouth so that the end of the locking block 201 facing away from the upper brace 10 is opposite to the opening of the locking groove 202. Then, he / she slightly retracts his / her upper teeth so that the locking block 201 is inserted into the locking groove 202, thereby locking the upper brace 10 and the lower brace 11 together and achieving the purpose of correcting the patient's deep overbite.
[0033] Although the upper and lower locking structures solve the technical problem of low effectiveness of the orthodontic appliances when used at night in the prior art, patients may sometimes forget to move their upper or lower teeth forward after putting on the upper braces 10 and lower braces 11. As a result, when the patient closes the upper braces 10 and lower braces 11, the locking block 201 will hit the locking protrusion 200 and generate a counter-vibration force, which affects the patient's user experience. In order to solve this technical problem, this embodiment has an inclined surface 203 on the side of the locking block 201 near the locking protrusion 200. The inclined surface 203 is used to assist the patient in closing the upper braces 10 and lower braces 11.
[0034] By setting the inclined surface 203, when the patient closes the upper braces 10 and lower braces 11 and forgets to move the upper or lower teeth forward, the locking protrusion 200 will contact the inclined surface 203 of the locking block 201. As the patient exerts force when closing, the locking protrusion 200 presses against the inclined surface 203 and pushes the locking block 201 forward along the inclined surface 203, so that the patient is guided to move the upper or lower teeth forward, so that the patient can move the upper or lower teeth forward in time, preventing the locking block 201 and the locking protrusion 200 from colliding and generating a counter-vibration force, thereby improving the patient's user experience.
[0035] Although the upper and lower locking structures solve the technical problem of reduced effectiveness of orthodontic appliances when used at night in the prior art, patients may forget to move their upper or lower teeth forward when opening the upper braces 10 and lower braces 11, which hinders the opening of the upper braces 10 and lower braces 11 and affects the patient's user experience. In order to solve this technical problem, this embodiment has an arc surface 204 on the side of the locking block 201 away from the locking protrusion 200. The arc surface 204 is used to assist the patient in opening the upper braces 10 and lower braces 11.
[0036] With the arc surface 204, when the patient opens the upper braces 10 and lower braces 11 and forgets to move the upper or lower teeth forward, the arc surface 204 of the locking block 201 will contact the bottom surface of the locking groove 202. As the patient exerts force, the arc surface 204 of the locking block 201 will abut against the bottom surface of the locking groove 202 and gradually move the locking block 201 forward, so that the patient is guided by the force to move the upper or lower teeth forward, so that the patient can move the upper or lower teeth forward in time and prevent the patient from being obstructed when opening the braces 1, thereby improving the patient's user experience.
[0037] In this embodiment, an arc-shaped portion 205 is provided at the connection between the arc surface 204 and the inclined surface 203. The arc portion 205 is used to prevent the connection between the arc surface 204 and the inclined surface 203 from forming a sharp end, thereby preventing the connection between the arc surface 204 and the inclined surface 203 from piercing the skin inside the patient's mouth, and further improving the patient's user experience.
[0038] In this embodiment, the upper brace 10, the lower brace 11, the upper locking structure, and the lower locking structure are all made of medical transparent plastic.
[0039] Medical transparent plastics specifically include polycarbonate (PC), polymethyl methacrylate (PMMA, i.e., acrylate), polystyrene (PS), K resin, copolyester, and polyurethane.
[0040] Made of medical transparent plastic, the upper brace 10, lower brace 11, upper locking structure, and lower locking structure have a visual effect, allowing medical staff to observe the orthodontic effect of the upper brace 10 and lower brace 11 combined with the upper and lower locking structures. They also enhance patient comfort and safety, are lightweight, biocompatible, and resistant to pollution; they are also resistant to chemical corrosion and impact.
[0041] Example 2, refer to Figure 3 The difference between this embodiment and embodiment 1 is that: the upper locking structure includes a locking wedge 210, which is fixedly disposed on the inner arc surface of the upper dental brace 10; the lower locking structure includes a locking recess 211 and a locking groove 212, which is fixedly disposed on the inner arc surface of the lower dental brace 11; the locking groove 212 is inclinedly opened inside the locking recess 211 and the opening is located on the side of the locking recess 211 opposite to the locking wedge 210; the locking wedge 210 and the locking groove 212 are adapted to each other; and the locking groove 212 is used to guide the locking wedge 210 to move the upper dental brace 10 forward.
[0042] Regarding the locking bevel block 210, it can be installed on the dental brace 1 by means of integration, heat fusion or other fixing methods. Regarding the locking recess 211, it can be installed on the dental brace 1 by means of integration, heat fusion or other fixing methods.
[0043] First, dental molds of the upper and lower teeth are made according to the patient's tooth shape. Then, a punch of locking bevel block 210 is installed on the inner arc surface of the dental mold of the upper teeth. Then, a punch of locking recess 211 is installed on the inner arc surface of the dental mold of the lower teeth. Finally, the upper dental crown 10 and lower dental crown 11 with upper and lower locking structures are cast using the dental molds of the upper and lower teeth. Before going to sleep at night, the patient puts the upper braces 10 on their upper teeth and the lower braces 11 on their lower teeth. Then the patient closes their mouth. During this process, the locking bevel 210 on the upper braces 10 gradually inserts into the locking groove 212. As the locking groove 212 guides the locking bevel 210, it moves the upper braces 10 forward, causing the patient's upper teeth to move forward as well, thereby correcting the deep overbite. Because the locking groove 212 is tilted, the locking bevel 210 requires a greater force to disengage from it. This increases the resistance the patient experiences when opening their mouth, reducing the likelihood of the patient's mouth involuntarily opening during deep sleep at night. This achieves the goal of solving the technical problem of low effectiveness of orthodontic appliances when used at night in existing technologies.
[0044] It should be noted that if the patient has functional malocclusion, the locking oblique block 210 can be set on the inner arc surface of the lower brace 11, and the locking recess 211 can be set on the inner arc surface of the upper brace 10. In this way, when the patient uses it, the locking oblique groove 212 will guide the patient's lower teeth forward through the locking oblique block 210, thereby achieving the purpose of correcting the patient's functional malocclusion.
[0045] Compared to Embodiment 1, the braces in this embodiment are more convenient for patients to use. When using the braces in this embodiment, patients only need to close their mouths to allow the locking bevel 210 to gradually insert into the locking groove 212. As the locking groove 212 guides the locking bevel 210, it moves the upper braces 10 forward, causing the patient's upper teeth to move forward as well, thereby correcting the deep overbite. Furthermore, because the locking groove 212 is tilted, the locking bevel 210 requires a greater force to disengage from the locking groove 212. This increases the resistance when the patient opens their mouth, thus reducing the possibility that the patient's mouth will involuntarily open when they are in deep sleep at night. This achieves the goal of solving the technical problem of the low effectiveness of orthodontic appliances when patients use them at night in the prior art.
[0046] When patients use the braces of Example 1, they need to move their upper or lower teeth forward before they can close their mouths. Although the inclined surface 203 of Example 1 improves the user experience, the resistance is still greater than that of this example. Patients still need to actively move their upper or lower teeth forward. Therefore, this example is more convenient to use than Example 1.
[0047] On the other hand, Example 1 has a more stable locking effect compared to this example. In Example 1, the patient needs to actively move their upper or lower teeth to open their mouth, while in this example, the locking groove 212 and locking block 210 restrict the patient, providing only greater resistance when the patient opens their mouth. The locking effect is lower than that of Example 1. Although the arc surface 204 in Example 1 can assist the patient in opening the upper braces 10 and lower braces 11, the patient still ultimately needs to actively move their upper or lower teeth. Therefore, Example 1 has a more stable locking effect compared to this example. In practical applications, Example 1 or Example 2 can be selected according to the patient's condition.
[0048] In this embodiment, the upper brace 10, the lower brace 11, the upper locking structure, and the lower locking structure are all made of medical transparent plastic.
[0049] Medical transparent plastics specifically include polycarbonate (PC), polymethyl methacrylate (PMMA, i.e., acrylate), polystyrene (PS), K resin, copolyester, and polyurethane.
[0050] Made of medical transparent plastic, the upper brace 10, lower brace 11, upper locking structure, and lower locking structure have a visual effect, allowing medical staff to observe the orthodontic effect of the upper brace 10 and lower brace 11 combined with the upper and lower locking structures. They also enhance patient comfort and safety, are lightweight, biocompatible, and resistant to pollution; they are also resistant to chemical corrosion and impact.
[0051] Example 3, referring to Figure 4 The difference between this embodiment and Embodiment 1 is that the upper locking structure includes a set of locking magnets 220, which includes two locking magnets 220, and the two locking magnets 220 are respectively fixedly disposed on both sides of the outer arc surface of the upper brace 10. The lower locking structure includes a set of attracting magnets 221, which includes two attracting magnets 221, and the two attracting magnets 221 are respectively fixedly disposed on both sides of the outer arc surface of the lower brace 11. The two attracting magnets 221 are used to attract the two locking magnets 220 one by one, so that the locking magnets 220 drive the upper brace 10 to move forward.
[0052] The locking magnet 220 and the attracting magnet 221 are both enclosed neodymium iron boron magnets or samarium cobalt magnets. The enclosed neodymium iron boron magnets or samarium cobalt magnets meet medical-grade standards and are harmless to the human body. They are mainly enclosed in a stainless steel or titanium alloy shell with high biocompatibility. Through precision processing, the shell retains a small gap at the contact surface or uses non-magnetic materials for isolation, so that the magnetic field can penetrate the shell in a directional manner and generate an attractive force with the magnet on the other side.
[0053] After medical staff create upper braces 10 and lower braces 11 based on the patient's dental impression, they then install a set of locking magnets 220 on the upper braces 10 and a set of attracting magnets 221 on the lower braces 11. Before going to sleep at night, the patient puts the upper braces 10 on their upper teeth and the lower braces 11 on their lower teeth. The patient then closes their mouth. At this time, the attracting magnets 221 are located on the side of the locking magnets 220 closest to the patient's lips and attract the locking magnets 220. The locking magnets 220 are moved forward by the attracting magnets 221, causing the upper braces 10 to move forward with the locking magnets 220, thereby correcting the patient's functional malocclusion. Furthermore, after the attracting magnets 221 attract the locking magnets 220, they greatly increase the resistance for the patient to open the braces 1, thus solving the technical problem of low effectiveness when patients use orthodontic appliances at night in existing technologies.
[0054] It should be noted that if the patient has a deep overbite, two locking magnets 220 can be fixed on both sides of the outer arc surface of the lower brace 11, and two attracting magnets 221 can be fixed on both sides of the outer arc surface of the upper brace 10. When the patient closes his mouth, the attracting magnets 221 are located on the side of the locking magnets 220 closer to the patient's lips and attract the locking magnets 220. The locking magnets 220 are moved forward by the attracting magnets 221, so that the lower brace 11 moves forward with the locking magnets 220, thereby achieving the purpose of correcting the patient's deep overbite.
[0055] Compared to Example 1, the braces in this embodiment are more convenient for patients to use. When using the braces in this embodiment, the patient only needs to close their mouth so that the attraction magnet 221 is located on the side of the locking magnet 220 close to the patient's lips and attracts the locking magnet 220. The locking magnet 220 is moved forward by the attraction magnet 221, so that the upper braces 10 moves forward with the locking magnet 220 to achieve the purpose of correcting the patient's functional malocclusion. Secondly, after the attraction magnet 221 attracts the locking magnet 220, it greatly increases the resistance for the patient to open the upper braces 10 and the lower braces 11, thereby solving the technical problem of low effectiveness when patients use the orthodontic appliances at night in the prior art.
[0056] When patients use the braces of Example 1, they need to move their upper or lower teeth forward before they can close their mouths. Although the inclined surface 203 of Example 1 improves the user experience, the resistance is still greater than that of this example. Patients still need to actively move their upper or lower teeth forward. Therefore, this example is more convenient to use than Example 1.
[0057] On the other hand, Example 1 has a more stable locking effect compared to this example. In Example 1, the patient needs to actively move their upper or lower teeth to open their mouth, while in this example, the patient is restricted by the attraction magnet 221 attracting the locking magnet 220. This results in greater resistance when the patient opens their mouth, and the locking effect is lower than that of Example 1. Although the arc surface 204 in Example 1 can assist the patient in opening the upper braces 10 and lower braces 11, the patient still ultimately needs to actively move their upper or lower teeth. Therefore, Example 1 has a more stable locking effect compared to this example. In practical applications, Example 1 or Example 3 can be selected according to the patient's condition.
[0058] Secondly, compared to Embodiment 2, the locking effect of this embodiment is more stable. Embodiment 2 only restricts the patient by using the locking groove 212 in conjunction with the locking block 210. The friction between the locking groove 212 and the locking block 210 is significantly lower than the friction between the attracting magnet 221 and the locking magnet 220 in this embodiment. Therefore, the resistance experienced by the patient when opening their mouth in this embodiment is significantly greater than that of the upper and lower locking structures in Embodiment 2. Thus, the locking effect of this embodiment is more stable than that of Embodiment 2. In practical applications, Embodiment 2 or Embodiment 3 can be selected according to the patient's condition.
[0059] In this embodiment, the upper brace 10 and the lower brace 11 are provided with a plurality of mounting structures 3 for mounting the upper locking structure and the lower locking structure, respectively. The plurality of mounting structures 3 correspond one-to-one with the locking magnet 220 or the attracting magnet 221. The locking magnet 220 and the attracting magnet 221 are both mounted on the brace through the mounting structure 3. The mounting structure 3 includes a mounting hole 30 opened on the brace and a fixing part 31 inserted into the mounting hole 30. The fixing parts 31 in the plurality of mounting structures 3 are fixedly connected one-to-one with the locking magnet 220 or the attracting magnet 221.
[0060] The number of mounting structures 3 is the same as the total number of locking magnets 220 and attracting magnets 221. For example, if there are four locking magnets 220 and attracting magnets 221, then there are also four mounting structures 3. The four mounting holes 30 are located in pairs on both sides of the outer arc surface of the upper brace 10 and the outer arc surface of the lower brace 11. The four fixing parts 31 are fixed at one end in the mounting hole 30, and the other end is connected to either the attracting magnet 221 or the locking magnet 220. The locking magnets 220 and attracting magnets 221 can be connected to the fixing parts 31 by adhesive bonding or heat fusion. The fixing parts 31 can be installed in the mounting hole 30 by heat fusion or adhesive bonding. Specifically, the fixing parts 31 can be integrally formed with the magnet and the locking magnet 220 or attracting magnet 221, or they can be made of plastic blocks bonded or heat-fused to the locking magnet 220 or attracting magnet 221.
[0061] Before installing the set of attraction magnets 221 on the lower brace 11, the two attraction magnets 221 must be fixedly installed on the fixing part 31 respectively. Then, the other end of the fixing part 31 is inserted into the mounting hole 30 of the lower brace 11, and the fixing part 31 is then fixed in the mounting hole 30 to complete the installation of the set of attraction magnets 221. Similarly, before installing the locking magnets 220 on the upper brace 10, the two locking magnets 220 must be fixedly installed on the fixing part 31 respectively. Then, the other end of the fixing part 31 is inserted into the mounting hole 30 of the upper brace 10, and the fixing part 31 is then fixed in the mounting hole 30 to complete the installation of the set of locking magnets 220.
[0062] In this embodiment, the upper dental brace 10, the lower dental brace 11, and the mounting structure 3 are all made of medical transparent plastic.
[0063] Medical transparent plastics specifically include polycarbonate (PC), polymethyl methacrylate (PMMA, i.e., acrylate), polystyrene (PS), K resin, copolyester, and polyurethane.
[0064] The upper brace 10, lower brace 11, and mounting structure 3, made of medical transparent plastic, have a visual effect, allowing medical staff to observe the orthodontic effect of the upper brace 10 and lower brace 11 combined with the upper and lower locking structures. They also enhance patient comfort and safety, are lightweight, biocompatible, and resistant to pollution; they are also resistant to chemical corrosion and impact.
[0065] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
