Description

Technical Field

[0001] This application belongs to the field of orthodontic technology, specifically relating to an orthodontic brace and orthodontic kit. Background Technology

[0002] In some cases of malocclusion, the typical presentation is a posterior position of the mandible relative to the maxilla, accompanied by labial inclination of the lower anterior teeth. When correcting this type of malocclusion, directly guiding the mandible forward (i.e., moving the lower anterior teeth and mandible forward simultaneously) will cause the lower anterior teeth to collide with the inner side of the upper anterior teeth during movement, creating a mechanical obstruction and preventing the mandible from moving further to the ideal position. Therefore, effectively creating the space required for mandibular advancement is a crucial issue worthy of further research. Summary of the Invention

[0003] This application provides an orthodontic braces and orthodontic kit, which can, but is not limited to, solving the problem that the lower anterior teeth collide with the inner side of the upper anterior teeth during movement, causing the mandible to be unable to continue moving forward to the ideal position.

[0004] The technical solution adopted in the embodiments of this application is: In a first aspect, this application provides an orthodontic brace, the orthodontic brace comprising: Occlusal pad, the occlusal pad extending in an arc shape, and the plane tangent to the two ends of the occlusal pad in the extending direction is defined as the rear end face; An upper outer stop, the upper outer stop being connected to the outer end of the occlusal pad and protruding from one side of the occlusal pad, the upper outer stop having a first middle portion, the first middle portion being positioned on the labial side of the upper anterior teeth, the first middle portion having a first inner wall surface, the vertical distance from the first inner wall surface to the rear end face being a first distance L1; and The lower outer guard is connected to the outer end of the occlusal pad and protrudes from the side of the occlusal pad away from the upper outer guard. The lower outer guard has a second middle part, which is used to be disposed on the labial side of the lower anterior teeth. The second middle part has a second inner wall surface, and the vertical distance from the second inner wall surface to the rear end surface is a second distance L2. Wherein, the first distance L1 and the second distance L2 satisfy: L1-L2≥4mm, so that the first inner wall surface is spaced apart from the upper anterior teeth, and the second inner wall surface is in contact with the lower anterior teeth.

[0005] In one embodiment, the first middle portion protrudes in a direction away from the rear end face.

[0006] In one embodiment, the first intermediate portion further has a first outer wall surface that is opposite to the first inner wall surface, and the first outer wall surface is an arc surface.

[0007] In one embodiment, the first intermediate portion further has a first outer wall surface and a transition surface, the first outer wall surface being a surface facing away from the first inner wall surface, the transition surface connecting the first outer wall surface and the first inner wall surface, and the transition surface being an arc surface.

[0008] In one embodiment, the second intermediate portion further has a second outer wall surface opposite to the second inner wall surface, and the vertical distance from the second outer wall surface to the rear end surface is a third distance L3, wherein the first distance L1 is greater than or equal to the third distance L3.

[0009] In one embodiment, in the height direction of the orthodontic braces, the height H1 of the first intermediate portion is greater than the height H2 of the second intermediate portion.

[0010] In one embodiment, the upper outer barrier 12 further includes a first upper cheek side portion and a second upper cheek side portion, the first upper cheek side portion and the second upper cheek side portion being respectively connected to the two ends of the first middle portion.

[0011] In one embodiment, the orthodontic braces further include a lower inner stop, which is connected to the inner end of the occlusal pad and spaced apart from the lower outer stop. The lower inner stop, the lower outer stop, and the occlusal pad together define a lower alveolar ridge for accommodating the mandibular teeth.

[0012] In one embodiment, the orthodontic braces are elastic.

[0013] Secondly, this application also provides an orthodontic kit, which includes orthodontic components and the aforementioned orthodontic braces, wherein the orthodontic braces are used to promote the retraction of the lower anterior teeth, and the orthodontic components are used to guide the mandible forward.

[0014] Compared with the prior art, the beneficial effects of this application are as follows: When a patient wears orthodontic braces, the first intermediate portion is positioned between the upper lip and the upper anterior teeth, and the second intermediate portion is positioned between the lower lip and the lower anterior teeth. Since the first distance L1 and the second distance L2 satisfy the condition L1-L2≥4mm, the first inner wall of the first intermediate portion is separated from the upper anterior teeth, and the second inner wall of the second intermediate portion is in contact with the lower anterior teeth. It is understandable that the upper lip will exert pressure on the first intermediate portion, and the lower lip will exert pressure on the second intermediate portion. Because the first inner wall is separated from the upper anterior teeth, the pressure from both lips will not be transmitted to the upper anterior teeth. Because the second inner wall is in contact with the lower anterior teeth, the pressure from both lips will be transmitted to the lower anterior teeth through the second intermediate portion. Under this continuous action, the lower anterior teeth will retract, thus increasing the horizontal distance between the lower and upper anterior teeth, thereby creating the space required for mandibular advancement and providing a spatial basis for subsequent mandibular guidance forward.

[0029] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0030] Please refer to Figures 1 to 4 This application provides an orthodontic brace 10, which includes: an occlusal pad 11, an upper outer guard 12, and a lower outer guard 13.

[0031] The occlusal pad 11 extends in an arc shape, and the planes tangent to the two ends of the occlusal pad 11 in the extending direction are defined as the rear end face M (see...). Figure 3 ).

[0032] The upper outer stop 12 is connected to the outer end of the occlusal pad 11 and protrudes from one side of the occlusal pad 11. The upper outer stop 12 has a first middle portion 121, which is used to be positioned on the labial side of the upper anterior teeth. The first middle portion 121 has a first inner wall surface 1211, and the vertical distance from the first inner wall surface 1211 to the rear end surface M is a first distance L1 (see...). Figure 4 ).

[0033] The lower outer stop 13 is connected to the outer end of the occlusal pad 11 and protrudes from the side of the occlusal pad 11 opposite to the upper outer stop 12. The lower outer stop 13 has a second middle portion 131, which is used to be positioned on the labial side of the lower anterior teeth. The second middle portion 131 has a second inner wall surface 1311, and the vertical distance from the second inner wall surface 1311 to the posterior end face M is a second distance L2 (see...). Figure 4 ).

[0034] Wherein, the first distance L1 and the second distance L2 satisfy: L1-L2≥4mm, so that the first inner wall surface 1211 is spaced apart from the upper anterior teeth, and the second inner wall surface 1311 is in contact with the lower anterior teeth.

[0035] Specifically, the occlusal pad 11 has an arch-shaped orientation, and the upper outer guard 12 and the lower outer guard 13 are respectively protruding on opposite sides of the occlusal pad 11. The upper outer guard 12 and the lower outer guard 13 are connected to the outer end of the occlusal pad 11 along the orientation of the occlusal pad 11, so that the orthodontic braces 10 presents an arch-shaped structure as a whole, which can match the shape of the patient's dental arch.

[0036] The occlusal pad 11 has two ends in the arcuate extension direction, and the rear end face M is tangent to these two ends. It should be noted that the rear end face M here is a virtual plane defined for the convenience of describing the orthodontic aligner 10 provided in this application, and does not imply that the rear end face M exists on the orthodontic aligner 10 product.

[0037] The upper outer stop 12 includes a first intermediate portion 121, which has a first inner wall surface 1211. The vertical distance from the first inner wall surface 1211 to the rear end surface M is a first distance L1. Since the upper outer stop 12 is curved and connected to the occlusal pad 11 along the arcuate direction, the first distance L1 from the first inner wall surface 1211 of the first intermediate portion 121 to the rear end surface M is not equal everywhere.

[0038] The lower outer stop 13 includes a second intermediate portion 131, which has a second inner wall surface 1311. The vertical distance from the second inner wall surface 1311 to the rear end face M is a second distance L2. Since the lower outer stop 13 is curved and connected to the occlusal pad 11 along the arcuate direction, the second distance L2 from the second inner wall surface 1311 to the rear end face M is not equal everywhere.

[0039] The first distance L1 and the second distance L2 satisfy the condition: L1-L2≥4mm. The specific values ​​of L1-L2 can be 4mm, 4.1mm, 4.3mm, 4.5mm, 4.9mm, 5mm, 5.2mm, 5.5mm, 5.6mm, 5.8mm, 6mm, 6.2mm, 6.5mm, etc. It should be noted that "L1-L2≥4mm" here means that "on the same cross-section, the difference between the first distance L1 from the first inner wall surface 1211 to the rear end surface M and the second distance L2 from the second inner wall surface 1311 to the rear end surface M is greater than or equal to 4mm (i.e., a comparison between the first distance L1 and the second distance L2 formed by the first inner wall surface 1211 and the second inner wall surface 1311 to the rear end surface M on the same cross-section)". The cross-section refers to a plane perpendicular to the rear end surface M and parallel to the height direction of the orthodontic aligner 10 (the height direction of the orthodontic aligner 10 is also the thickness direction of the occlusal pad 11). Figure 4 The diagram shown is a schematic diagram of the orthodontic brace 10 in the cross-sectional state of AA.

[0040] When the patient wears the orthodontic braces 10, the occlusal pad 11 is positioned between the maxillary and mandibular teeth, allowing the patient to bite and exercise the masseter muscle to correct occlusal function. The first intermediate portion 121 is positioned between the upper lip and the upper anterior teeth, and the second intermediate portion 131 is positioned between the lower lip and the lower anterior teeth. Because the first distance L1 is greater than the second distance L2, the first inner wall surface 1211 of the first intermediate portion 121 is spaced apart from the upper anterior teeth, and the second inner wall surface 1311 of the second intermediate portion 131 is in contact with the lower anterior teeth. Understandably, the upper lip will apply pressure to the first intermediate portion 121, and the lower lip will apply pressure to the second intermediate portion 131. Since the first inner wall surface 1211 is separated from the upper anterior teeth, the pressure from the upper and lower lips will not be transmitted to the upper anterior teeth. Since the second inner wall surface 1311 is in contact with the lower anterior teeth, the pressure from the upper and lower lips will be transmitted to the lower anterior teeth through the second intermediate portion 131. Under continuous action, the lower anterior teeth will retract, thereby increasing the horizontal distance between the lower and upper anterior teeth, thus creating the space required for the mandible to move forward, providing a spatial basis for subsequently guiding the mandible forward.

[0041] In one embodiment, please refer to Figure 1The first middle portion 121 protrudes away from the rear end face M. That is, the first middle portion 121 is outwardly convex, which can better ensure that when the orthodontic braces 10 are worn, the first middle portion 121 can be away from the upper front teeth to form a gap and avoid the pressure of the upper and lower lips being transmitted to the upper front teeth.

[0042] In one embodiment, please refer to Figure 1 The first intermediate portion 121 also has a first outer wall surface 1212 that is opposite to the first inner wall surface 1211, and the first outer wall surface 1212 is an arc surface. It is understood that when the orthodontic braces 10 are worn, the upper lip will be tightly pressed against the first outer wall surface 1212. In this embodiment, the first outer wall surface 1212 is set as an arc surface, so that the upper lip can adaptively fit against the first outer wall surface 1212, thereby improving wearing comfort.

[0043] In one embodiment, please refer to Figure 5 The first intermediate portion 121 also has a first outer wall surface 1212 and a transition surface 1213. The first outer wall surface 1212 is a surface that is opposite to the first inner wall surface 1211. The transition surface 1213 connects the first outer wall surface 1212 and the first inner wall surface 1211. The transition surface 1213 is an arc surface.

[0044] Understandably, when the orthodontic braces 10 are worn, the upper lip will not only press against the first outer wall surface 1212, but may also abut against the transition surface 1213. In this embodiment, the transition surface 1213 is set as a curved surface, which can avoid discomfort when the upper lip abuts against the transition surface 1213. The type of the transition surface 1213 can be, but is not limited to, a curved surface.

[0045] In one embodiment, please refer to Figure 4 The second intermediate portion 131 also has a second outer wall surface 1312 that is opposite to the second inner wall surface 1311. The vertical distance from the second outer wall surface 1312 to the rear end surface M is a third distance L3, and the first distance L1 is greater than or equal to the third distance L3.

[0046] "The first distance L1 is greater than the third distance L3" means that "on the same cross section, the first distance L1 from the first inner wall surface 1211 to the rear end surface M is greater than the third distance L3 from the second outer wall surface 1312 to the rear end surface M". The cross section refers to a plane that is perpendicular to the rear end surface M and parallel to the height direction of the orthodontic brace 10 (the height direction of the orthodontic brace 10 is also the thickness direction of the occlusal pad 11).

[0047] In this embodiment, by setting the first distance L1 to be greater than or equal to the third distance L3, it can be ensured that when the orthodontic braces 10 are worn, the distance between the first inner wall surface 1211 and the upper anterior teeth is larger. The larger the distance, the greater the pressure exerted by the upper lip on the first middle part 121, thereby more effectively promoting the retraction of the lower anterior teeth.

[0048] In one embodiment, please refer to Figure 4 In the height direction of the orthodontic aligner 10 (i.e., the thickness direction of the occlusal pad 11), the height H1 of the first intermediate portion 121 is greater than the height H2 of the second intermediate portion 131. This arrangement allows more of the first intermediate portion 121 to be covered by the upper lip, thus increasing wearing stability and preventing the orthodontic aligner 10 from detaching from the mouth during wear.

[0049] In one embodiment, please refer to Figure 2 The upper outer barrier 12 also includes a first upper cheek side portion 122 and a second upper cheek side portion 123, which are respectively connected to the two ends of the first middle portion 121 in the extending direction.

[0050] When the patient wears the orthodontic braces 10, both the first upper buccal side 122 and the second upper buccal side 123 are located inside the oral cavity, with the first upper buccal side 122 facing the left posterior teeth and the second upper buccal side 123 facing the right posterior teeth. By setting the first upper buccal side 122 and the second upper buccal side 123, the contact area between the upper inner band and the oral cavity can be increased, thereby avoiding the problem of the orthodontic braces 10 detaching from the oral cavity during wearing. It should be noted that, in the wearing state, the first upper buccal side 122 can be spaced apart from the left posterior teeth or can be fitted to the posterior teeth; similarly, the second upper buccal side 123 can be spaced apart from the left posterior teeth or can be fitted to the posterior teeth.

[0051] In one embodiment, please refer to Figure 6 The orthodontic braces 10 also include a lower inner stop 14, which is connected to the inner end of the occlusal pad 11 and is spaced apart from the lower outer stop 13. The lower inner stop 14, the lower outer stop 13, and the occlusal pad 11 together define a lower alveolar 15 for accommodating the mandibular teeth.

[0052] Specifically, the lower outer barrier 13 also includes a first lower cheek side portion 132 and a second lower cheek side portion 133 (see Figure 2The first lower buccal portion 132 and the second lower buccal portion 133 are respectively connected to the two ends of the second intermediate portion 131 in the extending direction. The lower inner stop 14 is spaced apart from the first lower buccal portion 132, the second intermediate portion 131, and the second lower buccal portion 133, thereby forming the lower alveolar ridge 15 together with the occlusal pad 11. When the patient wears the orthodontic braces 10, the mandibular teeth are located in the lower alveolar ridge 15, which can align the mandibular teeth. That is to say, the orthodontic braces 10 can also align the mandibular teeth while promoting the retraction of the lower anterior teeth.

[0053] In one embodiment, the orthodontic aligner 10 is elastic, meaning it can undergo elastic deformation under a certain external force. This type of elastically deformable orthodontic aligner 10 can also be called a silicone orthodontic appliance, which is more suitable for children in their growth and development stage. It should be noted that the term "silicone" in this context does not imply that the core material is silicone, but only indicates that it is soft and elastic to the touch. The orthodontic aligner 10 can be made of, but is not limited to, elastic materials such as thermoplastic elastomer (TPE), thermoplastic polyurethane elastomer (TPU), and silicone rubber.

[0054] Please refer to Figure 7 This application also provides an orthodontic kit, which includes an orthodontic element 20 and an orthodontic brace 10 as described in any of the above embodiments. The orthodontic brace 10 is used to promote the retraction of the lower anterior teeth, and the orthodontic element 20 is used to guide the mandible forward.

[0055] The orthodontic appliance 20 is used in conjunction with the orthodontic braces 10. For cases where the mandible is positioned posteriorly relative to the maxilla and is accompanied by labial inclination of the lower anterior teeth, the orthodontic braces 10 are first worn to promote the retraction of the lower anterior teeth, thereby creating the space required for the mandible to move forward. Then, the orthodontic appliance 20 is worn to guide the mandible forward, so that the mandible is in the ideal position.

[0056] For details regarding the orthodontic braces 10, please refer to the description in the embodiments, which will not be repeated here.

[0057] Among them, the orthodontic appliance 20 can be, but is not limited to, silicone appliances, fixed appliances, removable appliances, invisible appliances, etc., as long as it can guide the mandible forward, and there is no limitation here.

[0058] The technical means disclosed in this application are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
