Description

Technical Field

[0001] The utility model relates to the technical field of dental orthodontic medical treatment, in particular to an ultra-thin standard bracket with a strip-shaped arch without vertical holes. 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 strip straight wire arch bracket disclosed in the Chinese utility model patent announcement number CN 204468308 U includes a base plate and a bracket body disposed on the base plate, a bracket groove with a rectangular cross section is disposed on the bracket body, the bottom surface of the bracket groove forms a preset torque with the surface of the base plate, a strip arch wire is disposed in the bracket groove, and the wide surface of the strip arch wire fits with the bottom surface of the groove to generate automatic torque. When the wide surface of the strip arch wire fits with the bottom surface of the groove through conventional ligation, the teeth can generate automatic torque to reach the normal torque; the change of the bracket groove structure and the combination with the strip arch wire can simultaneously perform various tooth movements such as alignment, leveling, adduction, torque, etc.

[0005] Although the above-mentioned ribbon straight wire bracket can reduce the complexity of clinical operation, improve the efficiency and accuracy of tooth movement, and shorten the clinical correction period through automatic torque and synchronous tooth movement. However, since the bracket body is not only provided with vertical grooves interlaced with the horizontal bracket grooves (see the appendix of its manual), Figure 1 , located between the left and right rows of ligature wings), and a vertical hole is also provided. The related issues arising from this are as follows:

[0006] (1) The height of the bracket body relative to the base plate is 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;

[0007] (2) When used on the patient's teeth, it is easy to irritate the lip mucosa and cause discomfort;

[0008] (3) When chewing, the high bracket body is more susceptible to impact from food, and the impact of food may cause the bracket to fall off, affecting the smooth and continuous correction;

[0009] (4) Vertical troughs and vertical holes are prone to accumulating dirt and residual food residues and are difficult to clean, which is not conducive to maintaining oral hygiene and health.

[0010] Therefore, in order to further optimize the above products, we have improved the existing ribbon straight wire brackets. Utility Model Content

[0011] In view of the above problems, the utility model provides an ultra-thin standard bracket with a strip arch without vertical holes. By eliminating the vertical countersunk groove and the vertical hole structure on the bracket body, it can not only simplify the bracket processing technology and reduce the manufacturing cost, 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 falling off accidentally, 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.

[0012] The technical solution of the utility model is: an ultra-thin standard bracket with a strip-shaped arch without vertical holes, comprising a base plate and a bracket body arranged on the base plate, wherein a groove for cooperating with a strip-shaped arch wire is horizontally arranged on the bracket body, and the bottom surface of the groove forms a preset torque with the surface of the base plate, and when the strip-shaped arch wire is incorporated into the bracket groove, the wide surface of the strip-shaped arch wire fits with the bottom surface of the groove to generate automatic torque, and there is no vertical sink groove intersecting with the middle of the groove, and the base of the bracket body has no vertical hole, so that the base height of the bracket body can be fully reduced, and the bottom surface of the groove is close to the base plate, so that the overall height of the bracket body is reduced. The strip-shaped arch wire is a kind of arch wire with a rectangular cross section, and its characteristic is that the vertical surface of the strip-shaped arch wire is a wide surface, and the horizontal surface is a narrow surface.

[0013] Preferably, the groove width is greater than 0.025 inches, and the groove depth is less than or equal to 0.025 inches.

[0014] Preferably, the bracket body is rectangular as a whole, that is, the left and right sides of the bracket body are flush, and the upper and lower sides of the bracket body are flush.

[0015] Preferably, the bracket body has four ligation wings, which are divided into two rows, left and right, and the four ligation wings are respectively arranged and extended vertically.

[0016] Preferably, the periphery of the ligation wing, the periphery of the base and the periphery of the bottom plate are respectively provided with chamfers to eliminate sharp corners, so that the bracket is more rounded as a whole.

[0017] Preferably, a positioning mark is also provided on the ligation wing.

[0018] 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.

[0019] The beneficial effects of the present invention are as follows: the present invention can simplify the bracket processing technology and reduce the manufacturing cost by eliminating the vertical groove and vertical hole structure on the bracket body, and can also minimize the height of the bracket body, thereby achieving ultra-thin evolution of the bracket and improving 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.

[0030] like Figures 1 to 3 As shown, in this embodiment, the bracket body 1 has four ligation wings 4, which are divided into two rows, left and right, and the four ligation wings 4 are respectively arranged and extended vertically.

[0031] In this embodiment, the periphery of the ligation wing 4, the periphery of the base 7 and the periphery of the bottom plate 5 are respectively provided with chamfers, preferably, arc chamfers are adopted to eliminate sharp corners and make the bracket more rounded as a whole.

[0032] In this embodiment, a positioning mark is also provided on the ligation wing 4.

[0033] For this reason, the utility model can simplify the bracket processing technology and reduce the manufacturing cost by eliminating the vertical groove and vertical hole structure on the bracket body, and can also minimize the height of the bracket body, thereby achieving ultra-thin evolution of the bracket and improving 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.
