Abstract
Description
Technical Field
[0001] This utility model relates to the field of orthodontic technology, and in particular to an orthodontic oblique guide accessory structure. Background Technology
[0002] Skeletal Class II malocclusion is a common malocclusion in clinical practice. Its pathogenesis involves overdevelopment of the maxilla or underdevelopment of the mandible, or both. For patients with mandibular underdevelopment, functional orthodontic treatment during the growth and development period can help promote mandibular development, reduce the severity of skeletal deformity, and decrease the likelihood of orthognathic surgery.
[0003] In recent years, clear aligner technology has been used in orthodontic treatment, with transparent braces increasingly being combined with functional orthodontic treatment. This technology promotes mandibular development while enabling three-dimensional control of teeth, creating better conditions for mandibular protrusion and overcoming the shortcomings of traditional fixed and functional orthodontic treatments in terms of aesthetics and comfort. Current technology involves integrally molding mandibular protrusion guiding components on both sides of the clear aligner. These components include an upper guide pad and a lower guide pad, both with beveled sides. These bevels engage to create an interaction force that forces the mandible forward, thus correcting mandibular retrusion.
[0004] However, in the existing technology, the upper and lower guide pads are set up with their slopes facing each other, and there are no guardrails around them, which makes them more prone to lateral slippage, thus affecting the overall orthodontic effect.
[0005] Therefore, there is a need to provide an orthodontic guide accessory structure to solve the above problems. Utility Model Content
[0006] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an orthodontic oblique guide attachment structure that avoids lateral slippage between the contact surfaces of the upper and lower guide pads after tooth occlusion, thus ensuring the effectiveness of malocclusion correction.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is: an orthodontic guide accessory structure, including an upper guide pad and a lower guide pad; the upper guide pad and the lower guide pad are integrally formed on the upper and lower invisible braces, respectively; the upper guide pad extends with two guide wings at one end near the lower guide pad; the two guide wings and the first surface on the upper guide pad form a defined space; when closed, the defined space can partially enclose the lower guide pad, and the first surface can abut against the second surface on the lower guide pad.
[0008] Furthermore, the ends of the two guide wings near the lower guide pad are inclined away from the center line of the upper guide pad's width direction. This makes the cross-section of the two guide wings funnel-shaped, forming a defined space for guiding the movement of the lower guide pad.
[0009] Furthermore, the two guide wings are symmetrically arranged along the centerline of the upper guide pad's width direction. This ensures that the lower guide pad will not slip laterally against the upper guide pad in either the vertical direction, further guaranteeing the orthodontic effect after the braces are worn.
[0010] Furthermore, the guide wing is tilted at an angle of 10 to 60 degrees. This tilting angle serves two purposes: firstly, it prevents interference caused by the contact and contact between the second surface of the lower guide pad and the first surface of the upper guide pad during engagement; secondly, it limits the direction of movement of the lower guide pad, preventing lateral slippage between its second surface and the first surface of the upper guide pad.
[0011] Furthermore, the guide wing covers at least 2 mm of the lower guide pad in the first direction. The first direction refers to the length direction of the upper guide pad. The guide wing has a length of at least 2 mm in the first direction to ensure that the lower guide pad will never detach from the defined space during occlusion. The guide wing can always guide the movement and contact between the lower and upper guide pads, ensuring that the first surface on the upper guide pad will never slip against the second surface on the lower guide pad, thus guaranteeing the orthodontic effect.
[0012] Furthermore, there is a horizontal gap between the first surface of the upper guide pad and the second surface of the lower guide pad, and the gap is 0.2~2.5mm.
[0013] Furthermore, the guide wing includes a guide surface and an outer surface, the guide surface being a plane close to the lower guide pad, and the outer surface being an arc surface away from the lower guide pad.
[0014] Furthermore, the first surface is a smooth inclined surface that is recessed in the direction away from the lower guide pad, and the second surface is a smooth inclined surface that is inclined in the direction closer to the upper guide pad. The first surface and the second surface are matched.
[0015] The beneficial effects of this utility model are:
[0016] In this invention, two guide wings provide guidance for the relative movement of the lower guide pad and the upper guide pad, ensuring that the lower guide pad always moves within the limited space formed between the two guide wings and the first surface. This prevents lateral slippage between the contact surfaces of the upper and lower guide pads after the teeth are occluded, effectively avoiding tooth deviation during orthodontic treatment and further ensuring the effectiveness of malocclusion correction.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0023] See appendix Figures 1 to 4 As shown, an orthodontic guide accessory structure in this embodiment includes an upper guide pad 3 and a lower guide pad 4. The upper guide pad 3 and the lower guide pad 4 are integrally formed on the upper invisible braces 1 and the lower invisible braces 2, respectively. The upper guide pad 3 and the lower guide pad 4 are generally set in the posterior tooth area of the invisible braces. According to the patient's orthodontic needs, their size can be adjusted during the manufacturing process of the upper guide pad 3 and the lower guide pad 4, and they can be used for unilateral or bilateral orthodontic treatment.
[0024] Specifically, in some embodiments, the guide pad 3 is generally long enough to cover two to three of the patient's teeth.
[0025] Two guide wings 5 extend from the end of the upper guide pad 3 near the lower guide pad 4. These two guide wings 5 form a defined space with the first surface 6 of the upper guide pad 3. When closed, this defined space partially encloses the lower guide pad 4, and the first surface 6 abuts against the second surface 7 of the lower guide pad 4. Specifically, the defined space encloses the end of the lower guide pad 4 near the upper guide pad 3; the first surface 6 and the second surface 7 of the upper guide pad 3 refer to the opposite sides of the two guide pads.
[0026] During occlusion, the upper guide pad 3 and the lower guide pad 4 move relative to each other under the movement of the upper and lower teeth until the first surface 6 on the upper guide pad 3 and the second surface 7 on the lower guide pad 4 come into contact, that is, the first surface 6 and the second surface 7 fit together. Since the upper jaw has a greater force than the lower jaw, the upper guide pad 3 can exert a forward force on the lower guide pad 4 to force the lower jaw to remain in a forward protruding state during the long-term closure process, thereby achieving the effect of correcting the retraction of the lower jaw.
[0027] See appendix Figure 2 During the continuous opening and closing of the oral cavity, the two guide wings 5 provide guidance for the relative movement of the lower guide pad 4 and the upper guide pad 3, ensuring that the lower guide pad 4 always moves left and right within the limited space formed between the two guide wings 5 and the first surface 6. That is, the two guide wings 5 limit the distance the lower guide pad 4 moves in the left and right directions, so that there will be no lateral slippage between the contact surfaces of the upper guide pad 3 and the lower guide pad 4 after the teeth are occluded, effectively avoiding the occurrence of malocclusion during the orthodontic process.
[0028] The two guide wings 5 are inclined at their ends near the lower guide pad 4, away from the center line of the upper guide pad 3 in the width direction. This makes the cross-section of the two guide wings 5 funnel-shaped, forming a defined space for guiding the movement of the lower guide pad 4.
[0029] Specifically, the two guide wings 5 are set on the end of the upper guide pad 3 near the lower guide pad 4. The specific position is not limited, as long as the minimum distance between the two guide wings 5 is slightly greater than the length of the second surface 7 on the lower guide pad 4, so as to ensure that when the two guide wings 5 are engaged, the second surface 7 on the lower guide pad 4 can smoothly and completely abut against the first surface 6 on the upper guide pad 3, and the two guide wings 5 will not interfere with the movement of the lower guide pad 4 when engaged.
[0030] See appendix Figure 2 The two guide wings 5 are symmetrically arranged along the center line of the upper guide pad 3 in the width direction. This ensures that the lower guide pad 4 will not slip laterally with the upper guide pad 3 in either the vertical direction, further guaranteeing the orthodontic effect after the braces are worn.
[0031] The guide wing 5 is tilted at an angle of 10 to 60 degrees. The tilting angle can prevent interference caused by the contact and contact between the second surface 7 on the lower guide pad 4 and the first surface 6 on the upper guide pad 3 during engagement; on the other hand, it limits the movement direction of the lower guide pad 4 and prevents the second surface 7 on it from sliding against the first surface 6 on the upper guide pad 3.
[0032] The guide wing 5 covers the lower guide pad 4 by at least 2 mm in the first direction. The first direction refers to the length direction along the upper guide pad 3. The guide wing 5 is at least 2 mm long in the first direction to ensure that the lower guide pad 4 will never detach from the defined space during occlusion. The guide wing 5 can always guide the movement and contact between the lower guide pad 4 and the upper guide pad 3 to ensure that the first surface 6 on the upper guide pad 3 will never slip against the second surface 7 on the lower guide pad 4, thus ensuring the orthodontic effect.
[0033] There is a horizontal gap between the first surface 6 of the upper guide pad 3 and the second surface 7 of the lower guide pad 4, with a gap of 0.2~2.5mm. Specifically, the horizontal gap between the upper guide pad 3 and the lower guide pad 4 is consistent with the thickness of the invisible braces. During the fabrication of the guide pads, the upper guide pad 3 and the lower guide pad 4 are placed inside the braces model and integrally formed with the braces through a molding process. The horizontal gap between the lower guide pad 4 and the upper guide pad 3 ensures that, after integral forming and with the thickness of the braces, the thickness of the braces themselves will not interfere with the occlusal treatment of the lower guide pad 4 and the upper guide pad 3 when the patient uses them.
[0034] The guide wing 5 includes a guide surface 51 and an outer surface 8. The guide surface 51 is a plane close to the lower guide pad 4, and the outer surface 8 is an arc surface away from the lower guide pad 4.
[0035] In some embodiments, the connection between the guide surface 51 and the outer side surface 8 at the end away from the upper guide pad 3 is rounded; the two sides of the upper guide pad 3 and the lower guide pad 4 in the length direction are multiple continuous arc surfaces 9, and the connection between the outer periphery surfaces of the upper guide pad 3 and the lower guide pad 4 are all arc surfaces, so that the user's oral cavity will not be damaged after wearing.
[0036] The first surface 6 is a smooth, concave slope that tilts away from the lower guide pad 4, and the second surface 7 is a smooth, concave slope that tilts towards the upper guide pad 3. The first surface 6 and the second surface 7 fit together. The upper jaw has greater force than the lower jaw. When the user wears braces and closes their mouth, the upper guide pad 3 exerts a forward force on the lower guide pad 4, forcing the lower jaw to remain in a forward-protruding state during long-term closure, thereby achieving the effect of correcting mandibular retraction.
[0037] It should be noted that the first surface 6 can also be an inwardly concave, inclined arc surface. In order for the second surface 7 to fit perfectly with the first surface 6, it can be set as an outwardly protruding arc surface. After the user wears invisible braces with guide pads, it can also achieve the effect of correcting and shrinking the mandible.
[0038] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
