And the guiding hole 620 is opened in the third fitting region 930.

Referring to fig. 7 to 10, taking an arch wire with a rectangular cross section as an example, when the arch wire is pressed into the receiving groove 511 in use, the arch wire presses the stopping portion 830 down towards the receiving groove 511, the elastic portion 820 is elastically deformed, and the stopping portion 830 moves towards the receiving groove 511 under the pushing of the arch wire.

When the stopping portion 830 is pressed down, the stopping portion 830 deflects towards the side of the third mating zone 930, the second elastic member 850 enters the third mating zone 930 and abuts against the third mating zone 930, when the arch wire continues to move into the receiving groove 511, the arch wire cannot directly "cross" the stopping portion 830 due to the blocking of the stop block 840, at this time, the stopping portion 830 continues to approach towards the third mating zone 930 under the pushing of the arch wire, the second elastic member 850 is further elastically compressed, and the stop block 840 gradually moves away from the arch wire until the arch wire "crosses" the stop block 840.

After the archwire "clears" the stop 840, the stop 830 springs back toward the side of the archwire and against the archwire surface under the influence of the second resilient member 850 to facilitate advancement of the archwire into the first mating zone 910. In addition, the archwire also resiliently compresses the first resilient member 512 as it enters the receiving slot 511. When the arch wire is smoothly matched with the first matching area 910, the arch wire is simultaneously subjected to the abutting force of the stopping portion 830 and the elastic force of the first elastic member 512, and due to the special position structure design of the stopping portion 830, the first elastic member 512, the stopping block 840 and the first matching area 910, the stopping portion 830 and the first elastic member 512 simultaneously exert the abutting force thereon, and the arch wire is stably abutted against the first matching area 910 and is attached to the stopping block 840, so that the arch wire is stably locked in the accommodating groove 511.

And for the arch wire with a circular cross section, the arch wire is accommodated in the second matching area 920 after being locked, and the first elastic element 512 and the stopping part 830 are abutted with the arch wire, so that the arch wire is fixed. As shown in fig. 11 to 14.

Through the above design, the stability of the fit between the novel bracket 500 and the company is greatly improved. Because the novel bracket 500 is very well fitted to companies, the archwire can also in turn help to improve the stability of the novel bracket 500, so that the stability of the overall structure becomes higher.

In the orthodontic assembly of compound dentistry, maintenance part 100, arrow point card 200, little circle curve 300 and the arm 400 of holding down can provide basic mechanics for orthodontic work and support, and novel support groove 500 is gone up in the cooperation, can improve the cooperation stability between arch wire and the novel support groove 500 effectively, because the cooperation effect of novel support groove 500 and company is very good for the arch wire can also help improving the stability of novel support groove 500 in turn, thereby makes overall structure's stability become higher, has reduced the risk that novel support groove 500 drops effectively. In this way, the composite orthodontic assembly can better perform orthodontic treatment during use.
