Description

Technical Field

[0001] The utility model relates to the technical field of dental orthodontic medical treatment, in particular to an ultra-thin easy-torque ribbon-shaped orthodontic bracket. Background Art

[0002] The band-shaped orthodontic bracket uses an automatic torque mechanism and a fully synchronized tooth movement mechanism to solve the problem of the existing fixed correction technology that the tooth movement is carried out according to the inherent procedure, the efficiency is low, and the accuracy is difficult to control from the perspective of the fixed corrector structure and performance mechanism. It reduces the complexity of clinical operations, improves the efficiency and accuracy of tooth movement, and shortens the clinical correction cycle.

[0003] In recent years, band brackets have been widely accepted and praised by the market and patients due to their higher correction efficiency.

[0004] For example, a Chinese utility model patent publication number CN 210990828 U discloses an easy-torque band-shaped orthodontic bracket system, which includes a base plate and a bracket body. The bracket body includes a bracket base and ligature wings that are respectively cantilevered obliquely outward from the four sides of the bracket base. The bracket base and the ligature wings are an integrated structure. The four peripheral corners of the bracket base are rounded transitions, the lower side of the ligature wings is an upwardly arched arc surface, and a rounded curved transition is formed between the lower side of the ligature wings and the corresponding corners of the bracket base. An archwire groove is formed between the upper and lower rows of ligature wings, and the ligature wings on the left and right sides are respectively wide mouths.

[0005] Although the above-mentioned easy-torque ribbon arch orthodontic bracket system shortens the effective contact length between the archwire slot and the ribbon archwire by directly extending the ligature wings from the four corners of the bracket base, making it easier for the ribbon archwire to be inserted into the archwire slot and easier to ligature in place; the upper arch design on the lower side of the ligature wing and the arc chamfer design on the outer wall of the bracket body avoid jamming when the ligature wire slides, reducing the difficulty of clinical ligature operation. However, since the positioning midline between the left and right ligature wings on the bracket body is a groove structure (see the attached manual of its manual) Figure 1 , the depression between the left and right ligature wings), and a bolt hole structure (a vertical channel) is also provided on the base of the bracket body. The related issues caused by this are as follows:

[0006] (1) The positioning midline of the groove structure separates the left and right ligature wings into two sections, which weakens the overall structural strength of the bracket body, affects the structural performance of the ligature wings, and increases the risk of ligature wing breakage;

[0007] (2) The existence of an auxiliary structure at the base of the bracket causes the height of the bracket body relative to the base plate to be relatively high, or in other words, the thickness of the bracket body is relatively thick, making the bracket as a whole appear complex and clumsy and unable to be further refined;

[0008] (3) When used on the patient's teeth, the high bracket body is easy to irritate the lip mucosa and cause discomfort;

[0009] (4) When chewing, the bracket with a higher height is more likely to be impacted by food, and the impact of food may cause the bracket to fall off, affecting the smooth and continuous correction;

[0010] (5) The positioning center line of the groove structure and the bolt holes on the base are easy to accumulate dirt and residual food residues and are difficult to clean, which is not conducive to maintaining oral hygiene and health.

[0011] Therefore, in order to further optimize the above products, we improved the existing easy-torque band-bow orthodontic bracket system. Utility Model Content

The ribbon-shaped arch wire is a kind of arch wire with a rectangular cross-section, which is characterized in that the vertical surface of the ribbon-shaped arch wire is a wide surface, and the horizontal surface is a narrow surface.

[0014] Preferably, the positioning center line between the left and right ligation wings is an upward convex structure. Compared with the positioning center line of the previous groove structure, the upward convex structure can not only maintain the structural continuity of the left and right ligation wings, but also serve as a reinforcing rib of the left and right ligation wings, thereby enhancing the overall structural strength of the bracket body, improving the structural performance of the ligation wings, and greatly reducing the risk of ligation wing breakage.

Compared with the positioning center line of the previous groove structure, the convex structure can not only maintain the structural continuity of the left and right ligation wings, but also serve as a reinforcing rib of the left and right ligation wings, thereby enhancing the overall structural strength of the bracket body, improving the structural performance of the ligation wings, and greatly reducing the risk of ligation wing breakage.

[0025] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the technical scheme in the embodiment of the utility model will be described in more detail below in conjunction with the drawings in the embodiment of the utility model. In the drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The described embodiments are part of the embodiments of the utility model, not all of the embodiments. The embodiments and directional terms described below with reference to the drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. The embodiments of the utility model are described in detail below in conjunction with the drawings.

[0026] The specific structure and identification method of the present utility model are described below in conjunction with the accompanying drawings and examples.

[0027] like Figures 1 to 4 As shown, an ultra-thin easy-torque ribbon-shaped orthodontic bracket comprises a base plate 1 and a bracket body 2 arranged on the base plate 1, wherein the bracket body 2 comprises a bracket base 3 and ligature wings 4 respectively cantilevered obliquely outward from the surrounding parts of the bracket base 3, and a groove 5 for receiving a ribbon-shaped arch wire is formed between the upper and lower rows of ligature wings 4, the groove 5 is passed through from left to right, and there is no vertical depression intersecting with the groove 5 in the middle; the ligature wings 4 on the left and right sides respectively form wide openings, and the base of the bracket body 2 is not provided with bolt holes, so that the height of the base 3 of the bracket body 2 can be fully reduced, and the bottom surface of the groove 5 forms a preset torque with the surface of the base plate 1, and when the ribbon-shaped arch wire 6 is incorporated into the bracket groove 5, the wide surface of the ribbon-shaped arch wire 6 fits with the bottom surface of the groove to generate automatic torque, and the bottom surface of the groove 5 is close to the base plate 1, so that the overall height of the bracket body 2 is reduced. The ultra-thin easy-torque band-shaped orthodontic bracket can not only simplify the processing technology and reduce the manufacturing cost, but also minimize the height of the bracket body 2, realize the ultra-thin evolution of the bracket, and improve the comfort of use.

[0028] It is necessary to add that, Figure 3 As shown, the ribbon archwire 6 is an archwire with a vertical rectangular cross section, which is characterized in that the vertical surface of the ribbon archwire 6 is a wide surface, while the horizontal surface is a narrow surface. Under the same conditions, compared with the traditional square wire, the use of the ribbon archwire can make the depth of the groove shallower, which is also conducive to minimizing the height of the bracket body and realizing the ultra-thin evolution of the bracket. In addition, in this embodiment, compared with the prior art, the removed bolt hole or vertical hole structure can be assisted by orthodontic accessories if necessary, without the need to stack the structure on the bracket body.

[0029] like Figures 1 to 4As shown, in this embodiment, the positioning center line 7 between the left and right ligation wings is an upward convex structure. Compared with the positioning center line of the previous groove structure, the positioning center line 7 of the upward convex structure can not only maintain the structural continuity of the left and right ligation wings, but also become the reinforcing ribs of the left and right ligation wings 4, thereby enhancing the overall structural strength of the bracket body 2, improving the structural performance of the ligation wings 4, and greatly reducing the risk of ligation wings 4 breaking. Preferably, the upward convex structure is an upwardly protruding edge rib.

[0030] like Figures 1 to 4 As shown, in this embodiment, the four peripheral corners of the bracket base 3 are rounded transitions, the lower side of the ligation wing 4 is an upwardly arched arc surface, and a rounded curved surface transition is formed between the lower side of the ligation wing 4 and the corresponding corners of the bracket base to eliminate sharp corners and make the bracket more rounded as a whole.

[0031] like Figures 1 to 4 As shown, in this embodiment, the bracket base 3 and the ligation wing 4 are an integrated structure.

[0032] like Figures 1 to 4 As shown, in this embodiment, the ligation wings 4 of the bracket body 2 are distributed in an X shape as a whole. The ends of the ligation wings 4 are bent downward to form a buckling shape. The bottom of the groove 5 is provided with a position mark 8. The ligation wings 4 are provided with a positioning mark 9.

[0033] When in use, attach the base plate of the bracket to the outer surface of the tooth, allow the ribbon archwire to be incorporated into the groove, and tie it with the ligature wire (bypassing the ligature wing) to block the ribbon archwire in the groove. A preset torque is formed through the bottom surface of the groove and the surface of the base plate. Under the action of the preset torque, the tooth generates a correction force and gradually deflects. At the same time, as the tooth deflects, the twisting degree of the ribbon archwire gradually decreases, and the torque it generates also automatically and correspondingly decreases until the torque returns to zero; when the tooth is completely corrected in place, the tooth inclination returns to the tooth inclination angle it should have, and after a period of stable maintenance, the bracket and archwire can be removed.

[0034] For this reason, the utility model can not only simplify the bracket processing technology and reduce the manufacturing cost by eliminating the bolt hole structure on the bracket body, but also minimize the height of the bracket body, realize the ultra-thin evolution of the bracket, and improve the comfort of use; reduce the impact of food, prevent the bracket from accidentally falling off, ensure the correction process continues smoothly, and improve the accuracy and efficiency of tooth correction; reduce the structure that is easy to hide dirt and reduce food residue, which is conducive to keeping the oral cavity clean and healthy.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
