Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and more specifically, to a multi-functional orthodontic appliance for orthodontic use. Background Technology

[0002] Underbite is a common oral malocclusion characterized by the lower teeth overlapping the upper teeth, contrary to the normal bite relationship of "upper teeth covering lower teeth," commonly known as "prognathism." The causes of underbite are mainly divided into three categories: skeletal underbite, dental underbite, and functional underbite. Skeletal underbite is caused by uneven jaw development (i.e., small maxilla, large mandible); dental underbite is caused by abnormal tooth position, resulting in the lower teeth biting in front of the upper teeth; functional underbite is caused by bad oral habits, mainly tongue thrusting and other bad tongue habits.

[0003] Currently, the treatment of malocclusion relies on orthodontic appliances, but existing appliances typically have the following problems: Firstly, the orthodontic appliance is equipped with traction hooks. Currently, the traction hooks are usually connected to the base by being embedded in it. However, because the traction hooks need to withstand a lot of traction force during operation, and are only fixed by the wrapping force of the base, the traction hooks are easily pulled out of the base after long-term stress or aging of the base resin, resulting in loosening or even falling off, which seriously affects the treatment effect. Moreover, this embedded connection means that the position of the traction hooks cannot be adjusted after the base is formed, resulting in poor flexibility and greater difficulty in later maintenance. Secondly, existing orthodontic appliances can usually only target one of the causes of skeletal malocclusion, dental malocclusion, and functional malocclusion, and cannot take into account all dimensions at the same time, resulting in poor treatment effect. Utility Model Content

[0004] In view of this, in order to solve the above problems, this utility model provides a multi-functional orthodontic appliance for oral orthodontics.

[0005] This utility model is achieved through the following technical solution.

[0006] A multi-functional orthodontic appliance for oral orthodontics includes: a base; a fixed archwire mounted on the base, the fixed archwire including an inlay section embedded inside the base and two mounting sections extending outside the base, the two mounting sections being located on opposite sides of the base; two traction hooks, each fixedly connected to one of the mounting sections; a guide arch, mounted on the base, including a first orthodontic section and a second orthodontic section, the first orthodontic section abutting against the labial surfaces of the maxillary anterior teeth, and the second orthodontic section abutting against the labial surfaces of the mandibular anterior teeth; a tongue spring mounted on the inner side of the base, the tongue spring abutting against the inner side of the maxillary anterior teeth; and multiple tongue spikes, the multiple tongue spikes being spaced apart and mounted at the bottom of the base.

[0007] In the above scheme, the archwire base is used for the patient's teeth to bite down, achieving retention. The fixed archwire is stably connected to the archwire base through interlocking sections. The fixed archwire has two installation sections located outside the archwire base for mounting traction hooks on both sides. The traction hooks are used to connect to external fixation devices for traction. The first orthodontic segment of the guide arch has two sections, which contact the labial surfaces of the maxillary anterior teeth on both sides, stimulating maxillary bone growth through force. The second orthodontic segment is arc-shaped, which cooperates with the labial surface of the mandibular anterior teeth, guiding mandibular retraction by applying posterior force to the labial surface of the mandibular anterior teeth. Through the cooperation of the first and second orthodontic segments, the problem of underbite (prognathism) is corrected. The tongue spring abuts against the inner surface of the maxillary anterior teeth, improving dental problems by applying force to the teeth. The tongue spike is located at the bottom of the base, correcting bad tongue habits in the oral cavity through physical obstruction.

[0008] It should be noted that in traditional orthodontic appliances, the traction hook is directly connected to the base, with one end of the traction hook embedded in the base. Because the traction hook needs to withstand a lot of force during operation, it is easy for it to be pulled out of the base, resulting in loosening and seriously affecting the treatment effect. In contrast, the traction hook of this invention is fixedly installed on the mounting section of the fixed archwire exposed outside the appliance. Compared with direct connection to the base, installing the traction hook on the fixed archwire can effectively prevent the traction hook from loosening and improve the connection stability. In addition, the above-mentioned method of connecting the traction hook by embedding it in the base makes it impossible to adjust the position of the traction hook after the base is formed. However, the connection method of this application allows the position of the traction hook to be adjusted according to the actual situation after the base is formed, which is more flexible and makes subsequent maintenance of the traction hook easier.

[0009] In one example of this utility model, the traction hook is connected to the mounting section by welding.

[0010] The above solution provides a fixed connection method between the traction hook and the installation section. The welding method is simple to operate, and the connection effect is stable and highly corrosion resistant. It can be effectively applied to complex oral environments and ensure the reliability of the connection.

[0011] In one example of this utility model, both the fixed bowwire and the guide bow are made of bent metal wire.

[0012] In the above solution, the metal material has sufficient hardness, is not easily deformed or broken, and can withstand strict disinfection processes such as high temperature and high pressure. It can effectively kill bacteria and viruses, avoid cross-infection, and at the same time, it has strong wear resistance and corrosion resistance, resulting in a longer service life.

[0013] In one example of this utility model, the two ends of the fixed archwire are embedded inside the base and are bent into a U-shape.

[0014] In the above scheme, the U-shaped bend is located inside the base, which can enhance the connection stability between the fixed archwire and the base, ensuring that the fixed archwire will not shift.

[0015] In one example of this utility model, the guide bow further includes a connecting segment embedded inside the base, and the first correction segment is located between the second correction segment and the connecting segment.

[0016] In the above scheme, the connecting section is used to install the guide bow and the base. Both the connecting section and the first correction section are provided in two parts. The connecting section is the part of the guide bow near both ends, and the part between the two first correction sections forms the second correction section.

[0017] In one example of this utility model, the tongue spring is made of bent metal wire, one end of the tongue spring is embedded inside the base, and is bent to form a hook-shaped part.

[0018] In the above scheme, the hook-shaped part is located inside the base plate, which is used to securely connect the tongue spring to the base plate, so as to ensure stable force on the teeth and guarantee the treatment effect.

[0019] In one example of this invention, the base is made of a polymer material.

[0020] In the above-mentioned solution, the polymer material has a smooth surface to avoid causing discomfort to the patient, and it is easy to shape and has high processing flexibility, which can be customized to meet the patient's needs. In addition, the polymer material has excellent biocompatibility, making it safer to use in the oral cavity.

[0021] In one example of this utility model, an external traction and fixation device is also included, which is connected to the traction hook via a rubber band.

[0022] In the above scheme, the extraoral traction fixation device is worn on the patient's face and is connected to the traction hook located in the oral cavity by a rubber band to provide continuous and stable traction force and ensure the treatment effect.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: The traction hook of this application is fixedly connected to the fixed archwire installed on the base. Compared with the traditional embedded traction hook, it can effectively improve the anti-detachment ability and connection stability of the traction hook. At the same time, since the traction hook is not directly connected to the base, this split structure is conducive to the fine adjustment of the traction hook installation position and the later maintenance work. The flexibility and convenience are higher than the traditional embedded structure. The orthodontic appliance of this application can treat multiple dimensions simultaneously, including the jawbone, jaw position, teeth, and bad tongue habits, taking into account skeletal, dental, and functional factors, and can effectively improve the treatment effect of reverse overbite correction.

[0028] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0029] Please refer to Figure 1 and Figure 2A multi-functional orthodontic appliance for oral orthodontics includes a base 1, a fixed archwire 2, traction hooks 3, guide arches 4, tongue springs 5, and tongue spikes 6. The fixed archwire 2 is mounted on the base 1 and includes an inlay section 21 embedded inside the base 1 and two mounting sections 22 extending outside the base 1, located on opposite sides of the base 1. Two traction hooks 3 are provided, each fixedly connected to one of the mounting sections 22. The guide arches 4 are mounted on the base 1 and include a first orthodontic section 41 and a second orthodontic section 42. The first orthodontic section 41 abuts against the labial surfaces of the maxillary anterior teeth 7, and the second orthodontic section 42 abuts against the labial surfaces of the mandibular anterior teeth (not specifically shown in the figure). The tongue springs 5 ​​are mounted on the inner side of the base 1 and abut against the inner side of the maxillary anterior teeth 7. Multiple tongue spikes 6 are provided and spaced apart at the bottom of the base 1.

[0030] It should be noted that this orthodontic appliance is specifically designed to fit snugly against the upper anterior teeth (teeth #7) during installation. Figure 1 This is a side view of the appliance after it has been installed on the maxillary anterior tooth 7. Figure 2 The dashed line in the figure represents the part located inside the base 1.

[0031] The base 1 is used for the patient's teeth to bite and achieve retention. The fixed archwire 2 is securely connected to the base 1 through an inlay section 21 embedded within the base 1. The fixed archwire 2 has two installation sections 22 located outside the base 1 for mounting traction hooks 3 on both sides. The traction hooks 3 are used to connect with external fixation devices to ensure continuous traction force. The first orthodontic segment 41 of the guide arch 4 has two sections that contact the labial surfaces of the maxillary anterior teeth 7. By applying continuous force, it stimulates the maxilla to grow forward and improve maxillary hypoplasia. The second orthodontic segment 42 is arc-shaped and cooperates with the labial surface of the mandibular anterior teeth. By applying backward force to the labial surface of the mandibular anterior teeth, it guides the mandible to retract. Through the cooperation of the first orthodontic segment 41 and the second orthodontic segment 42 on the guide arch 4, the problem of reverse overbite (i.e., underbite) is corrected. The lingual spring 5 abuts against the inner surface of the maxillary anterior teeth 7. By applying force to the teeth, it improves dental problems. The tongue spike 6 is located at the bottom of the base, and it corrects bad tongue habits in the oral cavity by physically blocking them. As can be seen from the above, the orthodontic appliance of this application can treat multiple dimensions such as jawbone, jaw position, teeth and bad tongue habits at the same time, taking into account skeletal, dental and functional factors, and can effectively improve the correction effect of malocclusion.

[0032] Preferably, the traction hook 3 and the mounting section 22 are connected by welding. The welding process is simple, the connection is stable, and the corrosion resistance is strong. It can be effectively applied to complex oral environments and ensure the reliability of the connection.

[0033] It should be noted that traditional orthodontic appliances mainly connect the traction hook to the base by embedding a part of the traction hook into the base. However, since the traction hook needs to withstand a lot of traction force during operation, and the traction hook is only fixed by the wrapping force of the base, the traction hook is easily pulled out of the base after long-term stress or aging of the base resin, resulting in loosening or even falling off, which seriously affects the treatment effect. In contrast, the traction hook 3 of this application is welded to the installation section 22 of the fixed archwire 2 exposed outside the base, that is, it is indirectly fixed to the base 1 through the fixed archwire 2. The fixed archwire 2 and the traction hook 3 are rigidly connected by metal, which can greatly improve the anti-fall-off ability and connection stability of the traction hook 3. Furthermore, traditional embedded traction hooks cannot be adjusted in position after the base is formed. In contrast, with this application, if the position of the traction hook 3 needs fine-tuning after the base 1 is formed (e.g., if there is a deviation in the direction of traction force), the position can be adjusted simply by heating, disassembling, and re-welding, without damaging the main body of the base 1, offering greater flexibility. Directly embedded traction hooks, on the other hand, require grinding away the covering base for adjustment, which is not only time-consuming but may also weaken the base's strength, or even require remanufacturing the entire base, making it very troublesome. Additionally, the traction hook 3 in this application is not directly connected to the base 1. If the traction hook 3 subsequently experiences slight deformation, repair work can be performed directly on the base 1. In contrast, if a traditional embedded traction hook is damaged or deformed, part of the base needs to be removed for repair, and the base resin needs to be refilled after repair, making the process and operation more complex.

[0034] In this embodiment, both the fixed bow wire 2 and the guide bow 4 are made of bent metal wires. The metal material has sufficient hardness, is not easily deformed or broken, and can withstand strict sterilization processes such as high temperature and high pressure. It can effectively kill bacteria and viruses and avoid cross-infection. At the same time, it has strong wear resistance and corrosion resistance and a longer service life.

[0035] Preferably, both the fixed archwire 2 and the guide bow 4 are made of stainless steel. Stainless steel has high strength, strong corrosion resistance, low irritation to human oral tissues, and better biocompatibility.

[0036] In this embodiment, the two ends of the fixed archwire 2 are embedded inside the base 1 and are bent to form a U-shaped bend 221. The U-shaped bend 221 is located inside the base 1, which can enhance the connection stability between the fixed archwire 2 and the base 1, so as to ensure that the fixed archwire 2 will not shift.

[0037] Understandably, the U-shaped curve 221 is also part of the installation section 22.

[0038] In this embodiment, the guide bow 4 further includes a connecting segment 43, which is embedded inside the base 1. The first corrective segment 41 is located between the second corrective segment 42 and the connecting segment 43. The connecting segment 43 is used to install the guide bow 4 onto the base 1. Both the connecting segment 43 and the first corrective segment 41 are provided in two sections. The connecting segment 43 is the part of the guide bow 4 near both ends, and the part between the two first corrective segments 41 is the second corrective segment 42.

[0039] In this embodiment, the tongue spring 5 is made of bent metal wire, with one end of the tongue spring 5 embedded inside the base 1 and bent to form a hook-shaped portion 51. The hook-shaped portion 51 is located inside the base 1 and is used to securely connect the tongue spring 5 to the base 1, thereby ensuring stable force application to the teeth and guaranteeing the treatment effect.

[0040] In this embodiment, there are a total of 4 tongue springs 5, each of which abuts against a tooth. In actual implementation, the number of tongue springs 5 ​​can be adjusted according to actual needs.

[0041] In this embodiment, one end of the tongue spike 6 is embedded in the base 1, thereby achieving a secure connection with the base 1.

[0042] Preferably, the tongue spike 6 is also made of bent metal wire, and both the tongue spring 5 and the tongue spike 6 are made of stainless steel.

[0043] In this embodiment, the base plate 1 is made of a polymer material. The polymer material has a smooth surface to avoid causing discomfort to the patient, and it is easy to shape and has high processing flexibility, allowing for personalized customization to meet the patient's needs. In addition, the polymer material has excellent biocompatibility, making it safer for use in the oral cavity.

[0044] Preferably, the base 1 is made of resin.

[0045] In this embodiment, an extraoral traction fixation device (not specifically shown in the figure) is also included. The extraoral traction fixation device is connected to the traction hook 3 via a rubber band. The extraoral traction fixation device is worn on the patient's face and is connected to the traction hook 3 located inside the oral cavity via a rubber band to provide continuous and stable traction force, so that the various functional components in the oral cavity can apply force correctly to the affected area and ensure the treatment effect.
