Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oral orthodontics, in particular to an orthodontic accessory and an invisible correction device. Background Art
[0002] Orthodontics refers to correcting teeth and eliminating malocclusion. Invisible braces are a method of orthodontics, which involves entering the patient's teeth into a computer through digitization (3D scanner), simulating the movement of teeth through software, and then outputting the tooth movement process through a 3D printer. The braces are made using lamination technology and worn in the patient's mouth to achieve the effect of orthodontic treatment. In order to enhance the retention of invisible braces and control of teeth, accessories are often bonded to the teeth.
[0003] Most of the existing invisible braces accessories are set on the outside of the teeth, that is, the lip side. On the one hand, this will affect the appearance. On the other hand, when users remove the invisible braces, they are accustomed to picking the braces off from the outside of the teeth, which makes the braces bear greater pressure at the accessories. Moreover, since the invisible braces are made of soft material, they are prone to splitting under this pressure.
[0004] Therefore, it is necessary to provide an orthodontic accessory and an invisible correction device to solve the above problems. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide an orthodontic accessory and an invisible orthodontic device, which are easy to wear and remove, improve the aesthetics and the service life of the invisible orthodontic device, and avoid the phenomenon of invisible orthodontic device breakage.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: an orthodontic attachment, including a lingual attachment bonded to the inner side of the tooth; the lingual attachment includes an attachment surface that fits the back of the tooth, a buckle surface set close to the gums, and a lingual side surface, the lingual side surface is an arcuate surface that connects the attachment surface and the buckle surface and is convexly set toward the lingual side, and the lingual attachment is crescent-shaped. The lingual side surface is an arcuate surface, which can avoid the invisible braces from being easily broken when the invisible braces are set on the teeth, and on the other hand, it will not interfere with the invisible braces when they are brought in. It is obvious that the user is easier to operate when the arcuate surface is pressed into the teeth, making it more convenient to wear.
[0007] The lingual attachment is arranged on the inner side of the teeth, that is, the tongue side. When the user removes the invisible braces, pressure is applied to the invisible braces from the lip side to remove it. The pressure is dispersed when it is transmitted to the tongue side, and the magnitude of the force is much smaller than when it is on the lip side. It can ensure that when the invisible braces are removed, the lingual attachment will not cause the invisible braces to break, thereby effectively improving the service life of the invisible braces.
[0008] Furthermore, the two ends of the lingual attachment in the length direction are corners formed by the attachment surface, the buckle surface and the lingual side surface. That is, the attachment surface, the lingual side surface and the buckle surface constitute the whole crescent-shaped lingual attachment, and the crescent of the crescent-shaped lingual attachment must be oriented toward the gums, so as to realize the buckle of the buckle surface on it to the invisible braces.
[0009] Furthermore, an archwire is inserted into the groove of the lingual attachment, and a plurality of attachment brackets are connected by the archwire.
[0010] Furthermore, the side of the buckle surface away from the lingual side surface is connected to the attachment surface, so that the three surfaces constitute a complete lingual attachment, the lingual side surface at the top can facilitate the wearing of the invisible braces, and the buckle surface at the bottom can prevent the worn invisible braces from being easily separated from the teeth.
[0011] Furthermore, the buckle surface is an arcuate surface, and the arcuate surface is parallel to the jaw plane. The plane parallel to the jaw plane is used to limit the position movement of the invisible brace after wearing, so as to avoid affecting the subsequent correction effect.
[0012] Furthermore, the plane where the attachment surface is located is inclined or perpendicular to the plane where the side of the buckle surface away from the lingual side is located. The inclination or perpendicularity of the buckle surface and the attachment surface can limit the movement of the invisible braces in the vertical direction, thereby ensuring the wearing efficiency of the invisible braces.
[0013] Furthermore, the size of the lingual attachment is one ninth of the tooth position. The space on the lingual side of the oral cavity is smaller than the space on the labial side, so the volume of the lingual attachment can be reduced compared to general attachments. The size of the lingual attachment is about one ninth of the tooth position.
[0014] An invisible brace device includes an invisible brace sleeved on a tooth, wherein an inner wall of the invisible brace close to the tongue side is provided with a receiving groove matching a lingual accessory. The crescent-shaped lingual accessory is arranged on the back of the tooth and matches the receiving groove on the invisible brace, which has a good invisible effect and is more beautiful when worn by the user. The receiving groove can cover the lingual accessory, so that the buckle surface at the bottom of the lingual accessory can effectively buckle the invisible brace, limit its position movement after wearing, and will not affect the effect of subsequent correction.
[0015] Beneficial effects of the utility model:
[0016] In the utility model, the lingual attachment is arranged on the back of the teeth, and the attachment surface, the lingual side surface and the buckle surface cooperate with each other, which is convenient for wearing and removing, effectively improving the aesthetics and the service life of the invisible orthodontic device, and avoiding the phenomenon of the invisible orthodontic device breaking.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with 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 protection scope of the present invention.
[0022] See attached Figures 1 to 3 As shown, an orthodontic attachment in this embodiment includes a lingual attachment 1 bonded to the inner side of a tooth 5; the lingual attachment 1 includes an attachment surface 2 bonded to the back of the tooth 5, a buckle surface 4 arranged close to the gum, and a lingual side surface 3, wherein the lingual side surface 3 is an arcuate surface connecting the attachment surface 2 and the buckle surface 4 and convexly arranged toward the lingual side, and the lingual attachment 1 is arranged in a crescent shape. The lingual side surface 3 is an arcuate surface, which can prevent the invisible braces from being easily broken when the invisible braces are mounted on the teeth 5, and on the other hand, will not interfere with the insertion of the invisible braces. When the arcuate surface is pressed into the teeth 5, it is obvious that the user is easier to operate, making it more convenient to wear.
[0023] The lingual attachment 1 is arranged on the inner side of the tooth 5, that is, the tongue side. When the user removes the invisible braces, pressure is applied to the invisible braces from the lip side to remove it. The pressure is dispersed when it is transmitted to the tongue side, and the magnitude of the force is much smaller than that on the lip side. It can ensure that when the invisible braces are removed, the lingual attachment 1 will not cause the invisible braces to break, thereby effectively improving the service life of the invisible braces.
[0024] The buckle surface 4 is provided to limit the movement of the invisible braces to prevent the invisible braces from being separated from the lingual attachment 1 during use and from falling off easily.
[0025] The invisible orthodontic appliance is mounted on the tooth 5 bonded with the lingual attachment 1, so that the connection between the invisible orthodontic appliance and the tooth 5 is more stable. Specifically, the lingual attachment 1 can be arranged on the central incisors, lateral incisors, canines, second premolars, first molars and second molars on both sides.
[0026] The two ends of the lingual attachment 1 in the length direction are the corners formed by the attachment surface 2, the buckle surface 4 and the lingual side surface 3. That is, the attachment surface 2, the lingual side surface 3 and the buckle surface 4 constitute the whole of the crescent-shaped lingual attachment 1, and the crescent of the crescent-shaped lingual attachment 1 must be oriented toward the gums, so as to realize the buckle of the buckle surface 4 on the invisible braces.
[0027] In some embodiments, an archwire is inserted into the groove of the lingual attachment 1, and a plurality of attachment brackets are connected by the archwire.
[0028] The side of the buckle surface 4 away from the lingual side surface 3 is connected to the attachment surface 2. The three surfaces constitute the complete lingual attachment 1 as a whole, the lingual side surface 3 at the top can facilitate the wearing of the invisible braces, and the buckle surface 4 at the bottom can prevent the worn invisible braces from being easily separated from the teeth 5.
[0029] The buckle surface 4 is an arcuate surface, and the arcuate surface is parallel to the jaw plane. The plane parallel to the jaw plane is used to limit the position movement of the invisible brace after wearing, so as to avoid affecting the subsequent correction effect.
[0030] The plane where the attachment surface 2 is located is inclined or perpendicular to the plane where the side of the buckle surface 4 away from the lingual side surface 3 is located. The attachment surface 2 is bonded to the back of the tooth 5 by glue, and when bonding, it is necessary to ensure that the buckle surface 4 of the lingual attachment 1 is always parallel to the jaw plane. The buckle surface 4 is inclined or perpendicular to the attachment surface 2, which can limit the movement of the invisible braces in the vertical direction, thereby ensuring the wearing efficiency of the invisible braces.
[0031] The size of the lingual attachment 1 is one-ninth of the tooth position. The space on the tongue side in the oral cavity is smaller than the space on the labial side, so the volume of the lingual attachment 1 can be reduced compared to general attachments. The size of the lingual attachment 1 is about one-ninth of the tooth position. In some embodiments, the size of the lingual attachment 1 is set to one-ninth of the tooth position. When the lingual attachment 1 is too small, it is difficult to ensure the force value; when it is too large, it will lead to too large a force value, the invisible braces are not easy to remove, and the user has a strong foreign body sensation in the mouth, and the wearing comfort is not high.
[0032] An invisible brace device includes an invisible brace sleeved on a tooth 5, wherein the inner wall of the invisible brace close to the tongue side is provided with a receiving groove matching the lingual attachment 1. The crescent-shaped lingual attachment 1 is arranged on the back of the tooth 5 and matches the receiving groove on the invisible brace, which has a good invisible effect and is more beautiful when worn by the user. The receiving groove can cover the lingual attachment 1, so that the buckle surface 4 at the bottom of the lingual attachment 1 can effectively buckle the invisible brace, limit its position movement after wearing, and will not affect the effect of subsequent correction. The lingual side surface 3 of the lingual attachment 1 is an arc-shaped surface, so that the invisible brace can be more easily sleeved on the tooth 5 without causing additional interference, making it more convenient for the user to wear.
[0033] Working principle and usage process:
[0034] During installation, the lingual attachment 1 is glued to the outer surface of the tooth 5 to be corrected. During the pasting process, the edges and corners of the lingual attachment 1 are kept facing the gums. Then the invisible braces are worn. The tooth cavity on the invisible braces wraps around the tooth 5, and the receiving groove on it wraps around the lingual attachment 1. The lingual side surface 3 of the lingual attachment 1 is an arc-shaped surface, so it is easier to put the invisible braces on the tooth 5 without causing additional interference, making it more convenient for the user to wear.
[0035] It should be noted that, because the invisible braces are made of transparent polymer material, they have good elasticity and can achieve the above-mentioned wrapping.
[0036] When removing, the user picks off the invisible braces from the lip side. At this time, the hand applies force to the invisible braces. When the applied force is dispersed from the lip side to the lingual attachment 1, the force is much smaller than that on the lip side. This makes the elastic invisible braces less likely to split, which can greatly extend its service life and does not require frequent replacement.
