Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to an orthodontic appliance for adjusting the curvature of the dental arch. Background Technology

[0002] In orthodontic treatment, ectopic eruption and impacted teeth are common problems, easily leading to malocclusion and affecting oral function and facial aesthetics. Traditional braces mainly apply force in a single direction through the bending or torque of the archwire, which can easily result in uneven pressure distribution, leading to uneven alveolar bone resorption, increasing the risk of root resorption, and affecting the orthodontic effect. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an orthodontic appliance for adjusting the curvature of the dental arch, which can naturally align the teeth, reduce the risk of root resorption or alveolar bone damage, and ensure the orthodontic effect.

[0004] To solve the above-mentioned technical problems, this utility model provides an orthodontic appliance for adjusting the curvature of the dental arch, including an appliance body, wherein the appliance body has a tooth groove, and the tooth groove is located on the upper side and / or lower side of the appliance body.

[0005] The tooth groove has alternating pressing portions and avoidance portions. The pressing portions have a first width in a preset direction, and the avoidance portions have a second width in a preset direction. The first width is smaller than the second width, and the preset direction is the width direction of the tooth groove.

[0006] As an improvement to the above solution, the tooth groove has an outer edge and an inner edge. The inner wall surface of the outer edge has a plurality of spaced-apart convex surfaces. A transition surface is formed between any two adjacent convex surfaces. The squeezing part is formed between the convex surface and the inner edge. The clearance part is formed between the transition surface and the inner edge.

[0007] As an improvement to the above scheme, the plurality of inner convex surfaces are connected to the plurality of transition surfaces to form a wave shape.

[0008] As an improvement to the above solution, the outer wall surface of the outer edge forms a first wall surface, and the extension direction of the first wall surface is the same as the extension direction of the inner wall surface of the inner edge.

[0009] The inner convex surface forms a first thickness with the first wall surface, and the transition surface forms a second thickness with the first wall surface, wherein the first thickness is greater than the second thickness.

[0010] As an improvement to the above solution, the outer wall surface of the outer edge forms a second wall surface, the second wall surface having a plurality of spaced concave surfaces and a plurality of connecting surfaces, and a connecting surface is arranged between any two adjacent concave surfaces, the concave surfaces being arranged relative to the convex surfaces, and the connecting surfaces being arranged relative to the transition surfaces.

[0011] As an improvement to the above solution, the connecting surface protrudes outward from the concave surface, a third thickness is formed between the concave surface and the convex surface, and a fourth thickness is formed between the connecting surface and the transition surface, wherein the third thickness and the fourth thickness are equal.

[0012] As an improvement to the above solution, multiple concave surfaces and multiple connecting surfaces are connected to form a wave shape.

[0013] As an improvement to the above solution, the third thickness or the fourth thickness is 0.5mm-5mm.

[0014] As an improvement to the above solution, the body of the orthodontic appliance is made of an elastic material.

[0015] Implementing this utility model has the following beneficial effects:

[0016] In this embodiment, the user can bite down on the upper and lower alveoli of the orthodontic appliance body to correct the teeth to be treated. By forming alternating compression and clearance portions within the alveoli, and ensuring that the first width of the compression portion is smaller than the second width of the clearance portion, the alveoli of the orthodontic appliance body exhibit a narrow-wide periodic arrangement. During orthodontic treatment, the narrow compression portions compress the teeth, increasing the restraint force, while the wide clearance portions do not compress the teeth, dispersing the stress on the teeth. This allows the teeth to align naturally, while also dispersing the local impact of the orthodontic force, reducing the risk of root resorption or alveolar bone damage, and ensuring the orthodontic effect of the appliance body.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0023] This invention provides an orthodontic appliance for adjusting the curvature of the dental arch, such as... Figures 1 to 5 As shown, the orthodontic appliance for adjusting the arch curvature of the teeth includes an appliance body 1. The appliance body 1 has alveoli 2, which are located on the upper and / or lower sides of the appliance body 1. Specifically, the alveoli 2 are divided into upper alveoli 2 and lower alveoli 2. The upper alveoli 2 is for upper teeth to bite, and the lower alveoli 2 is for lower teeth to bite. The alveoli 2 has alternating compression portions 21 and clearance portions 22. The compression portions 21 have a first width in a preset direction, and the clearance portions 22 have a second width in a preset direction. The first width is smaller than the second width, and the preset direction is the width direction of the alveoli 2.

[0024] In this embodiment, the user can bite down on the upper and lower alveoli 2 of the orthodontic appliance body 1 to correct the teeth to be treated. By forming alternating compression portions 21 and relief portions 22 in the alveoli 2, and making the first width of the compression portion 21 smaller than the second width of the relief portion 22, the alveoli 2 of the orthodontic appliance body 1 presents a narrow-wide periodic arrangement structure. During orthodontic treatment, the narrow compression portions 21 can be used to compress the teeth, increasing the restraint force on the teeth, while the wide relief portions 22 do not compress the teeth, dispersing the stress on the teeth, thereby allowing the teeth to align naturally. At the same time, it disperses the local impact of the orthodontic force on the teeth, reducing the risk of root resorption or alveolar bone damage, and ensuring the orthodontic effect of the orthodontic appliance body 1.

[0025] Specifically, such as Figures 1 to 3 As shown, the tooth groove 2 has an outer edge 23 and an inner edge 24. The inner wall surface of the outer edge 23 has a plurality of spaced inner convex surfaces 231. A transition surface 232 is formed between any two adjacent inner convex surfaces 231. A pressing part 21 is formed between the inner convex surface 231 and the inner edge 24. A clearance part 22 is formed between the transition surface 232 and the inner edge 24. The inner convex surface 231 and the transition surface 232 are used to make the inner wall surface of the outer edge 23 form a curved wall surface. The teeth are pressed by the inner convex surface 231 protruding towards the tooth groove 2 to complete the orthodontic treatment of the teeth and ensure the alignment of the teeth.

[0026] It should be noted that the height of the inner convex surface 231 is determined based on the distance between the position of the tooth to be treated and the target position of the tooth after treatment. For example, when the distance between the position of the tooth to be treated and the target position of the tooth after treatment is 1 mm, the height of the inner convex surface 231 is 1 mm.

[0027] As a specific embodiment, multiple inner convex surfaces 231 are connected with multiple transition surfaces 232 to form a wave shape, so as to ensure a smooth transition between the inner convex surfaces 231 and the transition surfaces 232 while using the inner convex surfaces 231 to squeeze and correct the teeth. This avoids the formation of sharp connection structures such as right angles or sharp protrusions on the inner wall surface of the outer edge 23, which would cause sharp stimulation to the patient's teeth and ensure the user's wearing comfort when using the orthodontic appliance.

[0028] In addition, it should be noted that when a patient uses the orthodontic appliance for orthodontic treatment, the outer wall of the appliance body 1 will come into contact with the inner wall of the patient's mouth. In order to further ensure the orthodontic effect of the appliance, the shape of the outer wall of the appliance body 1 can be adaptively adjusted.

[0029] As a first optional embodiment, such as Figure 5 As shown, the outer wall surface of the outer edge 23 forms a first wall surface 233. The extension direction of the first wall surface 233 is the same as the extension direction of the inner wall surface of the inner edge 24. That is, when the inner wall surface of the inner edge 24 is a smooth curved surface, the first wall surface 233 is also a smooth curved surface to ensure the wearing comfort of the user when using the orthodontic appliance body 1. The inner convex surface 231 and the first wall surface 233 form a first thickness, and the transition surface 232 and the first wall surface 233 form a second thickness. The first thickness is greater than the second thickness, so that the wall thickness of the outer edge 23 has a periodic gradual change of thick-thin-thick. The thick wall surface formed between the inner convex surface 231 and the first wall surface 233 compresses the teeth, and the thin wall surface formed between the transition surface 232 and the first wall surface 233 adapts to the movement of the teeth, so that the teeth are naturally aligned and the orthodontic effect of the appliance is guaranteed.

[0030] As a second optional embodiment, such as Figure 2 and Figure 4 As shown, the outer wall surface of the outer edge 23 forms a second wall surface 234. The second wall surface 234 has a plurality of spaced concave surfaces 235 and a plurality of connecting surfaces 236. A connecting surface 236 is arranged between any two adjacent concave surfaces 235. The concave surfaces 235 are arranged relative to the convex surfaces 231, and the connecting surfaces 236 are arranged relative to the transition surfaces 232. This makes the outer wall surface of the outer edge 23 also form a curved wall surface, so as to use the convex surfaces 231 to squeeze the teeth for orthodontic treatment and ensure the orthodontic effect while reducing the overall volume of the orthodontic appliance body 1 and reducing the impact of the orthodontic appliance on the patient's facial appearance.

[0031] Furthermore, such as Figures 2 to 4As shown, the connecting surface 236 protrudes outward from the concave surface 235, and a third thickness is formed between the concave surface 235 and the convex surface 231. A fourth thickness is formed between the connecting surface 236 and the transition surface 232. The third thickness and the fourth thickness are equal, so that a uniform thickness is formed between the curved second wall surface 234 and the curved outer edge 23 inner wall surface, avoiding the location of abrupt thickness changes on the outer edge 23 of the alveolar dentition 2, reducing the acute angle formed by the inner or outer wall surface of the outer edge 23 of the alveolar dentition 2, ensuring the contact force of the tooth or oral cavity wall surface, and further ensuring the orthodontic effect on the teeth.

[0032] Specifically, the third or fourth thickness is 0.5mm-5mm to ensure that the outer edge 23 has a certain wall thickness and guarantees its strength. Preferably, the third or fourth thickness is 2.5mm. Of course, the third or fourth thickness can also be 1.5mm, 2mm, or 3.5mm, etc., depending on actual needs.

[0033] As a specific embodiment, multiple concave surfaces 235 and multiple connecting surfaces 236 are connected to form a wave shape, ensuring a smooth transition between the concave surfaces 235 and the connecting surfaces 236. This avoids the formation of sharp connecting structures such as right angles or sharp protrusions on the outer wall surface of the orthodontic body 1, reducing the stimulation of the soft tissues inside the oral cavity by the orthodontic body 1 when the user uses the orthodontic appliance, and further ensuring the user's wearing comfort when using the orthodontic appliance.

[0034] In this embodiment, the orthodontic appliance body 1 is made of an elastic material, such as silicone, to improve the adaptability of the orthodontic appliance body 1, while ensuring the biocompatibility of the orthodontic appliance body 1 and improving the patient's wearing comfort.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
