Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to a dental bracket and orthodontic appliance. Background Technology

[0002] During orthodontic treatment, the brackets are fixed to the tooth surface, and the archwire passes through the archwire groove of the bracket. The archwire is then ligated and fixed to the bracket by ligatures or wires. The orthodontic force of the archwire is transmitted to the tooth through the bracket, causing the tooth to make the expected slight displacement, thereby achieving the purpose of straightening the teeth.

[0003] However, existing dental brackets are relatively square in shape. For example, Chinese patent document CN222285652U discloses an orthodontic bracket and orthodontic appliance. The orthodontic bracket has sharp edges and corners, and the bracket body is divided into four small pieces by the archwire groove. It has a strong foreign body sensation and poor wearing comfort. Moreover, there are many small grooves, which easily trap dirt and grime, making it difficult to clean and easy to breed bacteria, posing certain hygiene and safety hazards. Utility Model Content

[0006] In one embodiment, the groove and the traction hook mounting slot are arranged perpendicular to each other.

[0007] In one embodiment, the bottom of the curved support wing is provided with a limiting portion that bends downward toward the base.

[0008] In one embodiment, the top of the curved support wing is provided with an alignment baseline groove.

[0009] In one embodiment, the alignment baseline groove is set at a preset angle to the groove.

[0010] In one embodiment, at least one of the curved support wings is provided with a label groove.

[0011] In one embodiment, the base base has an arc-shaped groove on the side away from the bracket.

[0012] In one embodiment, the base has rounded chamfers at its corners.

[0013] This utility model also discloses a dental orthodontic appliance, including an archwire and the aforementioned dental brackets, wherein a portion of the archwire is housed inside the dental brackets.

[0014] In one embodiment, the bowwire is made of any one of stainless steel, nickel-titanium alloy, β-titanium alloy, and cobalt-chromium alloy.

[0015] The above-mentioned solution of this utility model has the following beneficial effects:

[0016] This new type of dental bracket features two curved bracket wings on the bracket body, with only one groove between them. This design eliminates sharp edges, preventing the risk of scratching the mouth or irritating the oral mucosa, resulting in superior wearing comfort. The single groove structure avoids the problem of multiple grooves, reducing the accumulation of dirt and grime, facilitating cleaning and maintenance, and inhibiting bacterial growth, thus ensuring safety.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0024] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Furthermore, the term "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only; for example, “inner,” “outer,” “left,” “right,” and similar expressions are for illustrative purposes only and are not intended to limit the scope of the invention.

[0026] Please refer to Figures 1 to 5 This is a schematic diagram of the dental bracket 100 of this utility model. The dental bracket 100 includes a base 20, a bracket body 30 connected to the base 20, and two curved bracket wings 40 extending from the bracket body 30. A groove 31 is provided on the top of the bracket body 30, located between the two curved bracket wings 40. A traction hook mounting slot 32 is provided on the bottom of the bracket body 30. In use, multiple dental brackets 100 are first fixed to their corresponding tooth surfaces via the base 20. Adhesive is applied to the bottom surface of the base 20 and the tooth surface wings to fix the dental brackets 100. Then, a portion of the archwire is embedded into the groove 31, and rubber bands are tied around the dental bracket 100 to fix the archwire, thus completing the installation. Different thicknesses and materials of archwires are selected according to different stages of orthodontic treatment to achieve the corrective purpose.

[0027] Furthermore, the base 20 has an arc-shaped groove 21 on the side away from the bracket body 30. The arc-shaped groove 21 fits the tooth surface better, making it easier for the entire tooth bracket 100 to fit and be fixed to the tooth. In order to ensure that the base 20 is smoother and rounder and will not irritate the oral mucosa and corners of the mouth, the corners of the base 20 are provided with arc-shaped chamfers 22.

[0028] Furthermore, in this embodiment, the groove 31 and the traction hook mounting slot 32 are arranged perpendicularly to each other, wherein the traction hook mounting slot 32 is a rectangular slot, so that the traction hook is not easy to loosen or rotate during installation, and the installation stability is very good. With the setting of the traction hook mounting slot 32, the traction hook can be assembled and used according to the patient's usage, which is very flexible and practical.

[0029] Furthermore, the bottom of the curved bracket wing 40 is provided with a limiting part 41 that bends downward toward the base 30. The limiting part 41, the curved bracket wing 40, and the bracket body 30 form a limiting cavity, which facilitates the installation of rubber rings to fix the archwire. In this embodiment, a spherical surface structure is formed between the two curved bracket wings 40, with a smooth and rounded shape.

[0030] Furthermore, the top of the curved bracket wing 40 is provided with an alignment baseline groove 42, wherein the alignment baseline groove 42 is set at a preset angle with the groove 31. This preset angle can be 10°, 15°, 20°, etc., and is not limited to any one of them here. In this embodiment, the alignment baseline groove 42 is a shallow and narrow groove, which prevents dirt from accumulating, facilitates cleaning, greatly reduces the difficulty of cleaning, and brings convenience to patients for daily wear and use. The setting of the alignment baseline groove 42 facilitates the alignment and calibration of the dental bracket 100 with the teeth during installation, ensuring quick installation and correct positioning.

[0031] Furthermore, at least one curved bracket wing 40 is provided with a marking groove 43, and a marking is set inside the marking groove 43. This makes it easy to record each tooth bracket 100 so that the corresponding tooth can be quickly found and installed. Moreover, the groove structure ensures that the marking inside does not protrude above the surface of the curved bracket wing 40, does not create sharp edges, and does not cause any foreign body sensation when wearing it, making it very practical.

[0032] The aforementioned dental bracket 100, with two curved bracket wings 40 on the bracket body 30 and only one groove 31 between the two curved bracket wings 40, avoids sharp edges, eliminating the risk of scratching the mouth or irritating the oral mucosa during use, resulting in good wearing comfort. The overall structure has only one groove 31, avoiding the problem of multiple grooves 31, making it less prone to dirt and grime accumulation, facilitating cleaning and maintenance, and preventing bacterial growth, thus ensuring safety. The inclusion of traction hook mounting holes 32 allows for easy installation of traction hooks as needed, enabling the rubber bands to traction and position the upper and lower orthodontic appliances, enhancing practicality.

[0033] This utility model also discloses a dental orthodontic appliance (not shown), which includes an archwire (not shown) and the aforementioned dental brackets 100. A portion of the archwire is housed within the dental brackets 100. In use, one archwire is used with multiple dental brackets 100. The archwire is made of any one of stainless steel, nickel-titanium alloy, β-titanium alloy, and cobalt-chromium alloy.
