TECHNICAL FIELD

[0001] The present application relates to the technical field of tooth correction, and in particular to a kind of invisible retainer. BACKGROUND

[0002] Tooth corrector is a kind of device for correcting malocclusion, which can be freely taken off by patient or doctor, and is retained by the clamping action of clasp and the adsorption of mucosa. According to the need, spring and other accessories can be added to the corrector to generate correction force, so as to achieve the purpose of correcting malocclusion.

[0003] Retainer is a device worn to consolidate the treatment effect after tooth correction is completed and to keep teeth stable in new position. After tooth correction is completed, teeth are not stable in new position, and often need to wear retainer to keep teeth in new position on alveolar bone and wait for the remodeling of alveolar bone to reduce recurrence as much as possible.

[0004] In related art, the retainer is usually made of transparent plastic and steel wire. When the retainer is installed on teeth, the retainer wraps the teeth as a whole, which affects the use of teeth and the aesthetic appearance of teeth. CONTENT OF THE INVENTION

[0008] By adopting the above technical solution, the mouthpiece structure is closely fitted to the surface of the teeth of the corrector, which can provide retention force for the teeth after active treatment. The fixing structure is set on the gums of the corrector, which can increase the fitting area of the retainer in the oral cavity of the corrector, so that the wearing of the retainer is stable. When the corrector wears the retainer, the retainer only wraps the lower half of the teeth, and the corrector can use normal oral functions such as mastication. The retainer is invisible when it is exposed to the outside, which achieves the effect of invisible wearing and improves the aesthetic appearance when the retainer is worn. Therefore, the corrector is also more willing to wear it for a long time, which is more helpful to maintain the correction effect. At the same time, the retainer can be worn and removed by itself, and does not need to be specially disassembled and assembled every time. Only regular reexamination is needed, which is more convenient and practical.

[0009] Optionally, the outer side of the mouthpiece structure and the fixing structure is provided with a relief surface simulating the relief of the gums and teeth.

[0012] By adopting the above technical solution, the thickness of the inner side ring is 1-2mm, as the inner side ring is close to the inner side of the oral cavity, there is a larger space, and the foreign body sensation is not easy to occur when worn, and the 1.5-2mm thick inner side ring structure has high strength and is not easy to deform, which can play a major supporting and retaining role; the thickness of the outer side ring is 0.5-1mm, which is relatively thin, helping to improve the comfort of wearing, at the same time, the 0.5-1mm thick outer side ring can be bent and deformed, facilitating wearing; the inner side ring pulls and fixes the outer side ring, so that the retainer can fix the position of the teeth of the orthodontic patient without the assistance of steel wires.

[0013] Optionally, the opening of the mouthpiece structure away from the fixing structure is provided with a rounded corner.

[0014] By adopting the above technical solution, the rounded corner makes the opening of the mouthpiece structure away from the fixing structure have a smooth transition, which is used to reduce the damage of the retainer to the oral mucosa when worn, and improve the comfort of the retainer when worn.

[0015] Optionally, the mouthpiece structure and the fixing structure are made of polyethylene terephthalate-1,4-cyclohexane dimethyl ester (PETG) as the material.

[0016] By adopting the above technical solution, the retainer is made of PETG, which is almost invisible after being worn by the orthodontic patient and is not easy to be perceived, has better aesthetics, therefore, the orthodontic patient is also more willing to wear it for a long time, which helps to maintain the correction effect; and PETG can be recycled and used, which is friendly to the environment.

[0017] Optionally, the mouthpiece structure and the fixing structure are integrally formed.

[0018] By adopting the above technical solution, the manufacturing process of the retainer is simple and the operation is convenient.

[0019] Optionally, the mouthpiece structure and the fixing structure are integrally formed by using 3D printing technology.

[0020] By adopting the above technical scheme, the 3D printing technology can significantly shorten the manufacturing time of the retainer, improve the manufacturing efficiency of the retainer, and meanwhile, the 3D printing can manufacture a complex structure according to requirements, that is, the accuracy and quality of the manufacturing are ensured, and the problem of material waste in the traditional manufacturing process is reduced.

[0021] To sum up, the present application has at least one of the following beneficial technical effects:

[0022] 1. When the corrector wears the retainer, the retainer only wraps the lower half of the teeth, and the corrector can perform normal oral functions such as mastication, and has high practicability; and generally, the part of the teeth exposed outside cannot see the retainer, achieving the effect of invisible wearing, improving the aesthetic degree when the retainer is worn, so that the corrector is also more willing to wear it for a long time, which is more helpful to maintain the correction effect;

[0023] 2. The retainer can be worn and removed by itself, and does not need to be specially disassembled and assembled each time, but only needs regular reexamination, which is more convenient and practical;

[0024] 3. The thickness of the inner ring is 1.5-2mm, which plays a main supporting and retaining role, and the thickness of the outer ring is 0.5-1mm, which helps to improve the wearing comfort; the inner ring pulls and fixes the outer ring, so that the retainer can fix the position of the teeth of the corrector without the assistance of steel wires;

[0025] 4. The 3D printing technology can significantly shorten the manufacturing time of the retainer, improve the manufacturing efficiency of the retainer, and meanwhile, the 3D printing can manufacture a complex structure according to requirements, that is, the accuracy and quality of the manufacturing are ensured, and the problem of material waste in the traditional manufacturing process is reduced.
