Abstract
Description
Technical Field
[0001] This utility model relates to the field of orthodontic devices, and in particular to an orthodontic device for mandibular arch retraction. Background Technology
[0002] Orthodontic appliances are medical tools used to correct problems such as misaligned teeth and malocclusion. There are many types of appliances that are suitable for patients of different ages, degrees of malocclusion, and aesthetic needs.
[0003] Currently, to facilitate orthodontic treatment, metal brackets are bonded to the surface of each tooth. An archwire is then passed through each bracket, and a cast band is placed around the tooth as a fulcrum. When a target tooth needs correction, a hook on the corresponding metal bracket hooks one end of a rubber band, and the other end of the rubber band is placed across the patient's tongue. The hook on the other metal bracket then hooks the other end of the rubber band, allowing the elasticity of the rubber band to pull the target tooth to the target position.
[0004] Although the above method can achieve traction of the target tooth, the rubber band will compress the patient's tongue during the traction process, causing the patient to experience extremely severe discomfort. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide a mandibular retrusion correction device to solve the technical problem in the prior art where the rubber band compresses the patient's tongue during traction, causing extremely serious discomfort to the patient.
[0006] The present invention provides a mandibular retrusion correction device, including an orthodontic appliance for connecting with teeth in the working area and teeth in the non-working area, a cast band ring having at least one traction hook, and at least one elastic element. The cast belt loop is used to be fitted onto the teeth in the non-working area, and the traction hook is used to face the teeth in the working area. When the cast belt ring is fitted onto the tooth in the non-working area, a traction gap is formed between the traction hook and the tooth in the working area; One end of the elastic element is used to connect to a portion of the orthodontic appliance corresponding to the teeth in the working area, and the other end is connected to the traction hook by bypassing the tooth surface of the corresponding teeth in the working area. Through the elastic element, a portion of the orthodontic appliance is moved toward the traction gap to pull the teeth in the working area to the target position.
[0007] Furthermore, the orthodontic appliance includes an archwire and multiple brackets with hooks.
[0008] Furthermore, the plurality of brackets are respectively used to connect to the teeth in the working area and the teeth in the non-working area, the archwire is used to pass through the plurality of brackets, and the hook is used to hook one end of the elastic element.
[0009] Furthermore, the cast belt ring also includes a plurality of first ring members, at least one second ring member, and a connecting member; The connecting member is disposed between the second ring member and a first ring member adjacent to the second ring member.
[0010] Furthermore, the first ring members are respectively used to be fitted onto the multiple teeth on the first side, the second ring members are used to be fitted onto at least one tooth on the second side, and the connector is used to abut against the multiple teeth on the third side, so that the cast belt ring forms multiple fixed fulcrums on the multiple teeth through the first ring members, the second ring members, and the connector.
[0011] Furthermore, the corrective device also includes multiple traction hooks and multiple elastic elements; Each of the aforementioned traction hooks is used in conjunction with each of the aforementioned elastic elements, and each of the aforementioned traction hooks is used to target different teeth in the working area.
[0012] Furthermore, the plurality of said traction hooks are connected in sequence, and at least one of said traction hooks is connected to the second ring member.
[0013] Furthermore, the plurality of first ring members, the connecting member, the second ring member, and the traction hook are continuously cast and integrally formed.
[0014] Compared with the prior art, the mandibular retrusion correction device shown in this utility model has the following advantages: The orthodontic device for mandibular retrusion provided by this utility model includes an orthodontic appliance, a cast band with at least one traction hook, and at least one elastic element. During orthodontic treatment, the cast band can be fitted onto the teeth in the non-working area, and the traction hook can be positioned directly opposite the teeth in the working area. Utilizing the traction gap formed between the traction hook and the teeth in the working area, one end of the elastic element is connected to the corresponding portion of the orthodontic appliance around the tooth surface of the working area. The elastic element is then connected to the traction hook. Through the elasticity of the elastic element, the teeth in the working area can be pulled to the target position. This achieves orthodontic traction without requiring a rubber band to be placed across the patient's tongue, solving the problem in existing technologies where rubber bands compress the patient's tongue, causing discomfort during traction.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0021] Example Please see Figure 1 and Figure 2 As shown, this is an orthodontic device for mandibular retrusion according to an embodiment of the present invention. It includes an orthodontic appliance 100 for connecting with teeth 400 in the working area and teeth 400 in the non-working area. In this example, the orthodontic appliance 100 includes an archwire 110 and a plurality of brackets 120 with hooks 130. Specifically, the plurality of brackets 120 are respectively used to connect with teeth 400 in the working area and teeth 400 in the non-working area. The archwire 110 is used to pass through the plurality of brackets 120, and the hooks 130 are used to hook one end of the elastic member 300.
[0022] It should be noted that you should refer to [link / reference]. Figure 2 As shown, tooth 400 in the working area refers to the area 400 of the tooth that needs traction orthodontic treatment, which is... Figure 2 The 400mm teeth with thickened midline, and the 400mm teeth in the non-working area refer to the normal 400mm teeth area, which is... Figure 2 In actual operation, each tooth 400 in the working and non-working areas of the patient's oral cavity is connected to a bracket 120. The bracket 120 can be a metal bracket, and each bracket 120 has a hook 130.
[0023] To address the technical problem of existing orthodontic devices causing severe discomfort to patients during traction due to the elastic band compressing their tongue, the orthodontic device for mandibular retrusion shown in this example also includes a cast band loop 200 with at least one traction hook 210 and at least one elastic element 300. The casting ring 200 is used to be fitted onto the tooth 400 in the non-working area, and the traction hook 210 is used to face the tooth 400 in the working area. When the casting ring 200 is fitted onto the tooth 400 in the non-working area, a traction gap is formed between the traction hook 210 and the tooth 400 in the working area. One end of the elastic element 300 is used to connect to the part of the orthodontic appliance 100 corresponding to the tooth 400 in the working area, and the other end is connected to the traction hook 210 by passing around the tooth surface of the corresponding tooth 400 in the working area. Through the elastic element 300, the part of the orthodontic appliance 100 is moved toward the traction gap to pull the tooth 400 in the working area to the target position.
[0024] In practical implementation, a traction hook 210 is arranged on the cast band 200 so that when the cast band 200 is fitted on the tooth 400 in the non-working area, the traction hook 210 can be directly aligned with the tooth 400 in the working area. Utilizing the traction gap formed between the traction hook 210 and the tooth 400 in the working area, one end of the elastic element 300 is connected to the corresponding part of the orthodontic appliance 100 of the tooth 400 in the working area. The elastic element 300 is then connected to the traction hook 210 by passing around the tooth surface of the corresponding tooth 400. Through the elastic action of the elastic element 300, the tooth 400 in the working area can be pulled to the target position, achieving traction correction of the tooth 400 without having to cross the patient's tongue with a rubber band. This solves the problem in existing technologies where the rubber band compresses the patient's tongue, causing discomfort during the traction process.
[0025] To further understand this case, please refer to [the relevant documents / references]. Figure 2 As shown, Figure 2The thickened section in the middle line represents the working area of tooth 400, which is the tooth 400 that needs correction. This tooth 400 has a bracket 120 and a hook 130. When correction is needed, the hook 130 of the bracket 120 on the tooth 400 hooks one end of the elastic element 300, and the elastic element 300 is wrapped around the upper surface of the tooth 400. The other end of the elastic element 300 is then hooked by the traction hook 210 to achieve a traction effect on the tooth 400. Figure 2 The part marked on the middle arrow indicates the traction direction.
[0026] It should be noted that in this example, the rigidity of the traction hook 210 is sufficient to support the traction force of the elastic element 300 on the target tooth 400. Since the rigidity of the traction hook 210 can be adjusted through actual processing, it will not be specifically explained here.
[0027] It should be noted that the elastic element 300 can be a component with elastic function, such as an orthodontic rubber band or a traction chain. Since the elastic element 300 is a conventional prior art in this field, it is not specifically limited here.
[0028] In addition, to ensure that the cast belt ring 200 has sufficient stability on the tooth 400, in this example, the cast belt ring 200 also includes a plurality of first ring members 220, at least one second ring member 230 and a connector 240, wherein the connector 240 is disposed between the second ring member 230 and a first ring member 220 adjacent to the second ring member 230.
[0029] Specifically, multiple first ring members 220 are respectively used to be fitted onto multiple teeth 400 on the first side, a second ring member 230 is used to be fitted onto at least one tooth 400 on the second side, and a connector 240 is used to abut against multiple teeth 400 on the third side, so that the cast belt ring 200 forms multiple fixed fulcrums on multiple teeth 400 through the first ring member 220, the second ring member 230 and the connector 240.
[0030] Please refer to it again. Figure 2 As shown, the multiple teeth 400 on the first side refer to Figure 2 The left side teeth 400, and the multiple teeth 400 on the second side refer to... Figure 2 The right side teeth 400, and multiple teeth 400 on the third side refer to... Figure 2 The teeth 400 in the middle of the hook 210 can provide multi-point support by using the first ring 220, the second ring 230 and the connector 240 to ensure the stability of the hook 210 during the traction process.
[0031] Additionally, it should be noted that since different patients need to correct different numbers of teeth 400, in this example, the orthodontic device for mandibular retrusion is not limited to one traction hook 210 and one elastic element 300. It may also include multiple traction hooks 210 and multiple elastic elements 300. Each traction hook 210 is used in conjunction with each elastic element 300. Each traction hook 210 is used for different teeth 400 facing the working area. Specifically, multiple traction hooks 210 are connected in sequence, and at least one traction hook 210 is connected to the second ring 230.
[0032] It should be further noted that, given that the number of traction hooks 210 can be adjusted according to the number of teeth 400 that the patient needs to traction, no special limit is made here.
[0033] To ensure the strength of the cast ring 200, in some preferred embodiments, multiple first rings 220, connectors 240, second rings 230, and traction hooks 210 are continuously cast and integrally formed.
[0034] In summary, the orthodontic device for mandibular retrusion provided in this embodiment includes an appliance 100, a cast band 200 with at least one traction hook 210, and at least one elastic element 300. When the patient's teeth 400 are being corrected, the cast band 200 can be fitted onto the teeth 400 in the non-working area, and the traction hook 210 can be positioned directly opposite the teeth 400 in the working area. Utilizing the traction gap formed between the traction hook 210 and the teeth 400 in the working area, one end of the elastic element 300 is connected to the portion of the appliance 100 corresponding to the teeth 400 in the working area. The elastic element 300 is then connected to the traction hook 210 by passing around the tooth surface of the corresponding tooth 400. Through the elastic action of the elastic element 300, the teeth 400 in the working area can be pulled to the target position. This achieves traction correction of the teeth 400 without having to cross the patient's tongue with a rubber band, solving the problem in the prior art where the rubber band compresses the patient's tongue, causing discomfort during traction.
