Description

Technical Field

[0001] This invention belongs to the field of dental orthodontic instruments, and particularly relates to a double-wire bracket, especially a bracket that allows two wires to pass through simultaneously. Background Technology

[0002] Existing movable wing brackets bring great convenience to orthodontic clinics. However, in the later stages of alignment, an additional thin wire is often introduced to assist in providing torque, significantly shortening the correction time. For example:

[0003] CN202420062341.0 discloses a combined bracket, including a bracket base and a bracket wing. The bracket wing is slidably inserted into a longitudinal channel of the bracket base via inserts, forming a sliding connection structure between the two. A through hole parallel to the channel is provided in the middle of the bracket base, through which a stud of a split auxiliary tube is inserted. The bifurcated end of the stud passes through the through hole and bends to block the channel opening, thus constraining the bracket wing. This bracket provides a more convenient connection method for clinical use and meets the needs of different scenarios, but it also has the disadvantages of complex structure and large size.

[0004] The object of this invention is to find a more reasonable technical solution. Summary of the Invention

[0005] The purpose of this invention is to design a double-wire bracket that allows for the simultaneous insertion of both archwire and steel wire; another secondary purpose is to utilize the steel wire to form a self-locking limit on the bracket wings, ensuring safety during use.

[0006] The technical solution of this invention is implemented as follows: A double-wire bracket includes a bracket base and a bracket wing. The bracket wing is slidably inserted into the longitudinal slide of the bracket base by means of an insert, forming a sliding connection structure between the two. The bracket base has a base plate and an integral fixed wing. The base plate has two parallel vertical baffles protruding from its surface, forming a slide between the two vertical baffles. A tube hole is formed at the upper part of the vertical baffles, penetrating the slide. The fixed wing has an upward-facing ligating hook at the top and a downward-facing transverse slot for inserting the bowwire at the middle of the two vertical baffles. The bracket wing has an insert at its bottom and a downward-facing ligating hook at its top. An arc-shaped hook is formed at the upper end of the insert opposite to the downward-facing ligating hook. The insert is inserted into the slide on one side of the bracket base, forming an adjustable groove between the bracket wing and the fixed wing. The arc-shaped hook at the upper end of the insert can hook the wire passing through the tube hole.

[0007] The bracket wing is opposite to the direction of the downward ligating hook and is also machined with a bow wire cover. When the ligation is in place, the bow wire cover can cover the top of the adjustment groove.

[0008] As a preferred embodiment, the bracket seat is further provided with a transverse protrusion in the transverse slot separated by the fixed wing. The protrusion and the fixed wing form a fixed groove with a fixed width, and the protrusion and the bracket wing form an adjustable groove with an adjustable width.

[0009] The transverse slot on the bracket is an angled slot, the fixed wing and the protruding block facing each other are parallel inclined surfaces, forming an angled fixed groove, and the protruding block and the bracket wing facing each other are both right angle surfaces, forming a right angled adjustment groove.

[0010] The arc-shaped hook is either a circular arc-shaped hook or a long groove hook with rounded ends.

[0011] This invention directly processes a tube hole at the end of the bracket seat to allow the auxiliary steel wire to pass through. The other end is fitted with a bracket wing to form an adjustable groove, which allows for the insertion of the archwire and gradual ligation and tightening, forming a double-wire synergistic application of corrective force. In addition, the passing steel wire forms a self-locking limit on the bracket wing to prevent it from falling out. The whole invention has the characteristics of unique concept, compact structure and safe operation. Attached Figure Description

[0023] 3—Bowwire; 31—Steel wire; Detailed Implementation

[0024] Reference Figures 1 to 4 The double-wire bracket includes a bracket base 1 and a bracket wing 2. The bracket base 1 has a base plate 11 and an integral fixing wing 12. The base plate 11 conforms to the curvature of the tooth surface and has an adhesive texture on its bottom surface, which is common knowledge. The surface of the base plate 11 has two parallel vertical guards 13 protruding, forming a slide 14 between the two vertical guards 13. A tube hole 131 is opened in the upper part of the vertical guards 13 to pass through the slide, so that the auxiliary orthodontic wire 31 can pass through to help align the teeth. The fixing wing 12 is integrally located in the middle of the two vertical guards 13. The top is machined with an upward ligating hook 121, and the downward side forms a horizontal slot 15 for the archwire to be inserted. The fixing wing 12 spans the two vertical guards 13 to form a closed slide 14. This closed slide section is used to constrain the insert 21 of the bracket wing, forming a sliding connection structure between the two.

[0025] The bottom of the bracket wing 2 is connected to a pin 21, and the top is machined with a downward-facing ligating hook 22. The pin 21 and the downward-facing ligating hook 22 are offset from each other and face opposite directions. The upper end of the pin 21 is machined with an arc-shaped hook 23. The pin 21 is inserted into the slide 14 on one side of the bracket seat. An adjustable groove 151 with an adjustable width is formed between the bracket wing 2 and the fixed wing 12, which allows the archwire to be easily inserted into the groove. The arc-shaped hook 23 at the upper end of the pin 21 can hook the steel wire passing through the tube hole 131. The steel wire forms a limit to prevent the bracket wing 2 from coming out, thus achieving the purpose of self-locking.

[0026] Furthermore, the bracket wing 2, facing away from the downward ligating hook direction, is also machined with a wire cover 24. When the ligation is in place, the wire cover 24 can cover the adjustment groove 151, forming a multi-angle constraint on the wire 3 and maximizing the torque.

[0027] As a preferred embodiment, the bracket seat also features a transverse protrusion 152 in the transverse slot 15 separated by the fixed wing 12. The protrusion 152 and the fixed wing 12 form a fixed-width fixed groove 153, while the protrusion 152 and the bracket wing 2 form an adjustable groove 151. This can be selected according to different stages of the treatment. As shown in Figure 5, at the initial stage of treatment, when tooth misalignment is severe, the adjustable groove 151 can be used to allow the archwire 3 to enter. Under the action of the ligation rubber band, corrective force is gradually applied to the teeth. This is one of the advantages of the adjustable groove. As shown in Figure 6, in the later stages of treatment, when the teeth have basically moved to the designed target position, the archwire 3 can be adjusted into the fixed groove 153 to maintain its position and stabilize the jawbone. Furthermore, one advantage of having two types of grooves is that when changing the archwire 3, either a flat wire or a thick wire can be selected according to different clinical stages to provide corrective force from the vertical or horizontal directions, achieving a more humane treatment process.

[0028] In conjunction with the above-mentioned orthodontic process, the arc hook 23 on the bracket wing insert can be designed as an arc hook. Only when the bracket wing 2 moves into place will the arc hook 23 hook onto the steel wire 31 for self-locking, and the ligature rubber ring can be removed to maintain the stability of the bracket.

[0029] Furthermore, the transverse slot 15 on the bracket 1 is an angled slot, and the facing surfaces of the fixed wing 12 and the protrusion 152 are parallel inclined surfaces, forming an angled fixing groove 153. The angled fixing groove 153 generates a specific angle of torque on the horizontally inserted bow wire 3, while the facing surfaces of the protrusion 152 and the bracket wing 2 are both right angle surfaces, forming a right angle adjustment groove 151.

[0030] Reference Figure 7 As another example, the arc hook 23 is a long groove hook with rounded ends, which allows the pin 21 of the bracket wing to be hooked by the steel wire passing through the pipe hole when inserted into place, while allowing the bracket wing 2 to have a relatively long adjustment stroke, ensuring that the entire stroke of the adjustment groove 151 is constrained. In this example, there is no protruding stop design, only an adjustment groove 151.

[0031] The terms "up" and "down," "top" and "bottom," and "vertical" mentioned above are based on the vertical orientation shown in the illustration. The bottom and top surfaces are defined as follows: the former faces inwards from the drawing, and the latter faces outwards from the drawing. Figure 1 Directional markers.
