Referring to fig. 1-5, the present invention provides an embodiment:

an auxiliary device for the distal movement of molar teeth comprises a transmission rod 1 and a force-adding accessory 8, wherein the transmission rod 1 comprises a plurality of arch wire sleeves 11, a connecting rod 12, a traction hook 13 and a lingual button 14, a buccal tube A42 is attached to a second molar tooth 7, a buccal tube B43 is attached to a first molar tooth 6, a bracket A41 is attached to a cuspid 5, a plurality of arch wire sleeves 11 are respectively arranged close to the middle of a buccal tube A42, close to the middle of a buccal tube B43 by 0.5mm and close to the middle of a bracket A41, and a bracket B44 is attached to a first bicuspid 9. The bracket device 4 comprises a bracket A41, a buccal tube A42, a buccal tube B43 and a bracket B44. Wherein the archwire slot 11, which is attached to the bracket a41, is fixedly attached with a lingual button 14 in a direction away from the gum.

When the transmission rod 1 is used, a model or oral cavity scan needs to be taken from the mouth of a patient to obtain the three-dimensional information of the dental arch and the related bracket device 4. The arch wire sleeve 11 is arranged at the middle position close to the buccal tube A42, the middle position 0.5mm close to the buccal tube B43 and the middle position close to the bracket A41, the molar teeth are moved far and middle in batches, after the second molar tooth 7 moves far and middle 0.5mm, a space is reserved for the movement of the first molar tooth 6, at the moment, the arch wire sleeve 11 in the middle position of the first molar tooth 6 can play a role, and then the first molar tooth 6 and the second molar tooth 7 are moved simultaneously. The computer is utilized to simulate the tooth correction to obtain the space required by aligning the teeth, and the far-middle amount of the molar teeth can be relatively accurately controlled by adjusting the position of the arch wire sleeve 11 in the far-middle of the canine 5. The method can also be divided into large, medium and small models for batch production, and the manufacturing process is not limited to 3D printing. The towing hook 13 is placed in the gingival position of the archwire slot 11 distal to the cuspid 5. A rubber band can be hung between the tongue side buckle 14 and the anchorage nail 2, which plays an auxiliary role in the orthodontic process, and the patient can take the rubber band according to the requirement.

The transmission rod 1 can be used for the upper jaw teeth and the lower jaw teeth, and the using methods of the upper jaw teeth and the lower jaw teeth are the same.

The traction device also comprises an anchorage nail 2, wherein the anchorage nail 2 is connected with the traction hook 13 through a force-adding accessory 8. The use of the towing hook 13 in conjunction with the anchorage pin 2 to urge the first and

second molars

6, 7 to move distally, allows the amount of movement of the molars to be controlled by customization, wherein the mesial spacing of the cuspid 5 bracket a41 to the first bicuspid 9 bracket B44 translates into maximum work for the drive rod 1, and the precise distal movement of the molars is achieved by designing the distance of the cuspid 5 bracket a41 to the mesial spacing of the first bicuspid 9 bracket B44.

The arch wire sleeve 11 is a square tube or a round tube. The square arch wire 3 or the round arch wire 3 can be selected according to the treatment requirement, and the arch wire sleeve 11 is selected to be a square pipe or a round pipe, wherein the arch wire sleeve 11 of the square pipe can slide on the square arch wire 3, so that the transmission rod 1 does not rotate on the square arch wire 3.

One side of the towing hook 13 is serrated. The towing hook 13 needs to be connected with the force-applying accessory 8, and the sawtooth shape is convenient to be connected with the force-applying accessory 8 and is not easy to fall off.

The archwire slot 11 is flared distally. The bell mouth shape is smooth, so that the arch wire 3 can conveniently penetrate through the bell mouth shape.

The number of arch wire sleeves 11 is 3. 3 archwire sleeves 11 are respectively placed mesially against buccal tube A42, mesially against buccal tube B43, 0.5mm, and mesially against bracket A41.
