Oval through holes 5 penetrating through the bracket base 1 are respectively arranged on two sides (namely, near and far positions) of the bracket base 1, and the oval through holes 5 are perpendicular to the archwire slot 4, as shown in fig. 3 and 4. The oval through hole 5 can be internally penetrated by a traction rod 6, two ends of the traction rod 6 extend out of the oval through hole 5, one end of the traction rod 6, which is positioned on one side of the sliding cover 2, is provided with an anti-falling component 7 for preventing the traction rod 6 from sliding out of the oval through hole 5, the tail end of the other end of the traction rod 6 is expanded to form a circular hole 8 or a C-shaped hole 9, as shown in fig. 6 and 7, the other end of the traction rod 6 in fig. 6 and 7 forms a circular hole 8, and the other end of the traction rod 6 in fig. 8 forms a C-shaped hole 9. The traction rod 6 is of a detachable design, for example, the traction rod 6 is arranged into two sections, and the two sections are connected through clamping or bolts, so that the traction rod can be placed in the oval through hole 5 of the bracket base 1 or detached from the oval through hole 5 of the bracket base 1 according to requirements.
Two flat archwires 10 can be placed in the front-back direction in the archwire slot 4, as shown in fig. 1, 2 and 8, two stacked flat archwires 10 are adopted, the flat archwires 10 are easier to clamp into the archwire slot 4, the gap between the archwire slot 4 and the flat archwires 10 is reduced, and alignment is facilitated. The appliance system also includes a series of corrective archwires, particularly flat square wires 10 that can be placed back and forth.
The two ends of the arch wire slot 4 are arranged obliquely to the tooth surface, or a semicircular groove 12 which is inclined to the tooth surface is arranged in the middle of the two ends of the arch wire slot 4, as shown in figure 5. The inclined length of the two ends of the archwire slot 4, as in the inclined section 11 of figures 3, 4, 6 and 7, is 1mm. The proximal and distal middle bottoms of the archwire slots 4 are inclined 1mm toward the tooth surface, and the single-sided tight ligation more easily causes deformation of the archwire, thereby better aligning the teeth. The semicircular grooves 12 inclined to the tooth surface are arranged, and the circular archwire placed in the archwire slot 4 is easier to deform at the two ends of the archwire slot 4, so that the teeth are aligned more easily.
The bracket base body 1 is also provided with an oval through hole 5 penetrating through the bracket base body 1 near the middle part, one end of the traction rod 6 is bent back and clung to the bracket base body to form an anti-drop component 7, the cross section of the part of the traction rod 6 positioned in the oval through hole 5 is an oval cross section, the oval cross section of the traction rod 6 is matched with the cross section of the oval through hole 5, the structure of the traction rod 6 is as shown in fig. 9 and 10, and the other end of the traction rod 6 is provided with a round hole 8 or a C-shaped hole 9, which can be determined according to a round arch wire convenient to install.

The two bracket bodies 3 respectively extend to the direction far away from the archwire slot 4 and form bracket wings, the edges of the bracket wings are designed to be excessive in arc, and the distance from the slot bottom (especially the near-far middle edge) of the bracket slot 4 to the bottom of the bracket wings is 0.008-0.010 inch, which is smaller than the diameter of the thinnest aligned steel wire. This distance allows sufficient friction between the ligature wire and the archwire when the ligature wire is ligatured to the bottoms of the two brackets 3.
After the self-locking correction system which is beneficial to multidimensional control is bonded and fixed on the tooth surface, two stacked flat archwires 10 are clamped into the archwire slot 4, and the circular archwires pass through the circular holes 8 or the C-shaped holes 9 at the end parts of the traction rods 6, so that the tooth torque is improved, namely the tooth root alignment is assisted. When ligature wires are ligated at the bottoms of the two bracket bodies 3, because the distance between the bottom of the bracket body 3 and the bottom of the arch wire groove 4 is small, positive pressure exists between the ligature wires and the flat arch wires 10, and the friction force between the ligature wires and the flat arch wires 10 is increased through tight ligation, so that the teeth can be stabilized, the movement of the teeth is reduced, and the anchorage is enhanced. The ligature wire 13 is tightly ligated by bypassing the bracket wings on one side through the oval through hole, and the main arch wire is more easily deformed so as to better align the torsion teeth, as shown in fig. 11.
