Further, the arch wire is a square wire, the buccal tube is a round buccal tube, and the diameter of the buccal tube is larger than the height and width of the arch wire.

Further, the rubber ring of the force-applying component is pulled to twice the original diameter, the rubber ring is a rubber ring for ligation, and the pulling wire is a ligation wire that passes through the rubber ring to form a closed-loop structure.

Further, the arch wire (1) is a titanium-nickel square wire of 0.021×0.025 inches; the buccal tube (2) has an inner diameter of 0.036 inches and a length of 0.25 inches.

Compared with the prior art, the utility model has the following beneficial effects:

In the utility model, the full-size rocking chair arch wire (bracket groove 0.022×0.028 inches) on the one hand increases the friction between the bracket and the arch wire, which is beneficial to prevent the distal drift of the anterior teeth; on the other hand, the rocking chair arch wire The wire increases the root-lingual torque of the anterior teeth and enhances the anchorage of the anterior teeth. In this way, the force generated by the deformed rubber ring in the force-reinforcing component pulls the target molars to move mesially and close the interdental space of the defective teeth, which is sufficient. The anchorage of the overall group of teeth. After the end of the rocking chair arch wire is fixed on the molar by the buccal tube, the deformation force generated by the arch wire in the horizontal and vertical directions can cause the buccal inclination of the molar, thereby effectively preventing the lingual inclination during the mesial translation of the lower molar. The buccal canal is bonded to the molars mesially and obliquely, causing the deformation of the archwire to produce a force that is opposite to the trend of mesial torsion and mesial inclination during the mesial translation of the molars, thereby reducing the proximal Middle torsion and mesial tilt occur. Therefore, the utility model can realize the mesial translation of the lower molars, and prevent the occurrence of mesial twisting, mesial inclination and lingual inclination during the mesial translation of the lower molars. The utility model is suitable for the mesial translation correction of lower molars.

As shown in FIG. 1 , a lower molar mesial translation assembly mainly includes an arch wire 1 , a buccal tube 2 , a plurality of brackets 3 , an independent traction hook 4 and a booster assembly 5 . Wherein, in use, the buccal tube 2 is used to be fixed on the molars to be translated in a mesial oblique manner, and multiple brackets 3 are used to be attached to the multiple bicuspids and anterior teeth in front of the molars to be translated in the lower jaw in sequence, One end of the arch wire 1 is connected to the buccal tube 2, and the rest of the wire passes through the grooves of multiple brackets (3) and is fixed in sequence, and is in the shape of a rocking chair bow. The independent traction hook 4 is used to set on the same side as the molar to be translated Between the lower lateral incisors and the mandibular canines, the force component 5 is connected between the traction hook of the buccal tube and the independent traction hook.

In particular, in order to increase the frictional force between the bicuspid region and the arch wire 1, a bicuspid ligature wire 5 and a bicuspid ligature ring 6 are also provided to double-ligate the arch wire 1 attached to the first 1. On the bracket 3 of the second bicuspids to prevent the bicuspids from drifting away.

In order to maintain the stability in the horizontal direction, the arch wire 1 adopts a square wire, specifically a 0.021×0.025-inch titanium-nickel square wire; in order to reduce the friction between the arch wire 1 and the buccal tube 2, the buccal tube 2 adopts a round tube Buccal tube, and the diameter of the buccal tube 2 is greater than the height and width of the archwire 1, specifically a round tube buccal tube with an inner diameter of 0.036 inches and a length of 0.25 inches can be selected. At the same time, the round tube buccal tube 2 cooperates with the rocking chair arch wire 1 made of square wire, and the elastic force generated by the horizontal deformation of the arch wire 1 can cause the buccal inclination of the molars and prevent the lingual inclination of the molars. In this implementation, bracket 3 selects MBT straight wire arch metal bracket.

In order to achieve the mesial translation of the traction mandibular second molar, the force-applying assembly uses a rubber ring 51 to cover the traction wire 52, the traction wire 52 is wound on the independent traction hook 4, and the rubber ring 51 is pulled to The other end is sleeved on the traction hook 21 of the buccal tube 2 after twice the original diameter. During specific implementation, a rubber ring for ligation can be selected as the rubber ring 51 , and the traction wire 52 is restrained in a way that the ligation wire passes through the rubber ring and is wound into a closed-loop structure.
