Abstract
Description
Technical Field
[0001] This invention relates to the field of fixed orthodontic treatment, specifically to a bracket with adjustable groove width. Background Technology
[0002] Brackets are an important component of fixed orthodontic technology. They are directly bonded to the tooth crown surface with adhesive. The archwire applies various types of orthodontic forces to the teeth through the brackets. Their main function is to fix the archwire, thereby enabling the archwire to function better, transmit orthodontic forces, and control the three-dimensional movement of the teeth at one time to achieve the purpose of orthodontic treatment.
[0003] Existing technologies also include some brackets, such as patent applications with application numbers 202422258703.6, 201810392969.6, 202310411914.6, 202421181556.0, and 200720008768.9. However, their disclosed technical solutions still have issues such as: fixed bracket groove width, incisors on the mesial and distal sides, which can expand the tooth axial tilt range during tooth movement, resulting in rapid early tooth movement but difficulty in achieving tooth alignment later; when aligned with round wires, teeth can move with greater axial tilt within the lower wide groove, but after switching to square wires, the archwire can only move within the upper narrow groove with limited range. Due to the double-layered grooves, the orthodontic appliance is relatively thick, resulting in poor comfort. When teeth are significantly rotated in the early stages, the archwire cannot be inserted into the groove, wasting more time in early alignment. Clinically, it requires constant monitoring of tooth tilt and complex procedures to adjust the angle between the bracket base and body, making this approach difficult to implement. While better control of tooth tilt generally improves treatment efficiency, this is because during tooth retraction, more attention is paid to the movement of the canines, and canine tilting is easier to achieve than overall movement. This approach favors overall movement and is not conducive to improving treatment efficiency. Although the gingival wings of the bracket can be moved as a whole to increase the groove width, this movement of the bracket wings, rather than individual movement, leads to poor adjustment of tooth tilt. Summary of the Invention
[0004] The present invention aims to overcome the shortcomings of the prior art by providing a groove width adjustable bracket.
[0005] This application provides the following technical solution: An adjustable groove width bracket includes a base plate, characterized in that: a platform is provided on the base plate, and a pair of first bracket wings and a pair of movable second bracket wings are fixedly connected on the platform, the pair of first bracket wings are diagonally distributed, the pair of second bracket wings are also diagonally distributed, and tying wires are wound on one of the first bracket wings and the other of the second bracket wings along the width direction of the platform.
[0006] Based on the above technical solutions, the following further technical solutions are also possible: The platform is provided with a pair of through holes corresponding to the second support wing. One end of the through hole is provided with a notch. The through hole and the bottom plate below it form a groove-shaped structure with one end open. The groove-shaped structure is a dovetail groove. The lower end of the second support wing is provided with a dovetail that matches the sliding groove.
[0007] The platform is a rectangular plate structure.
[0008] The pair of grooves are distributed in parallel to each other.
[0009] Advantages of the invention: This invention has a simple structure and is easy to use. It solves the problems that may occur when brackets are bonded during orthodontic treatment. For example, when there is a difference between the bracket axis and the tooth axis, the movable wing can effectively adjust the axis of the appliance. In cases where the anterior teeth need to be retracted during orthodontic treatment, the bilateral canines are the key teeth for retraction in the anterior region, and the axial control is relatively complex. The movable wing appliance can effectively solve this problem. Attached Figure Description

Figure 4 yes Figure 3 Left view of (a). Detailed Implementation
[0011] like Figure 1-4 As shown, an adjustable groove width bracket includes a base plate 1, a rectangular plate-shaped platform 2 connected to the base plate 1, and a pair of first bracket wings 3 fixedly connected to the platform 2, the pair of first bracket wings 3 being diagonally distributed on the platform 2.
[0012] A pair of elongated through holes 5 are distributed on platform 2, with a notch 5a at one end of each through hole 5 communicating with the outer circular surface of platform 2. This allows the through hole 5 and the bottom plate 1 below it to form a groove-shaped structure with one open end, which is a dovetail groove. A second support wing 4 is slidably connected to each groove-shaped structure, and a dovetail corresponding to and cooperating with the groove 5 is provided at the lower end of the second support wing 4.
[0013] The second bracket wing 4 and the first bracket wing 3 are evenly distributed around the vertical rod section a, which is perpendicular to the platform 2. A hook section b is connected to the vertical rod section a. A pair of first bracket wings 3 and a pair of second bracket wings 4 form a bowwire groove 6 that corresponds to and engages with the bowwire.
[0014] Usage process: When in use, the bow wire 7 is inserted into the bow wire groove 6, then the position of the second bracket wing 4 is adjusted, and then the first bracket wing 3 and the second bracket wing 4, which are distributed along the width direction of the base plate 1, are wrapped with ligature wire 8 and tightened to complete the fixation. Figure 4 The middle arrow indicates the direction of movement of the second bracket wing 4 during actual use.
