[0002] Teeth that have passed the tooth eruption period but still fail to erupt in the jaw tissue are called impacted teeth. The unerupted teeth need to be surgically combined with a traction device to be pulled out. Conventional impacted tooth traction methods and tools include fixed bracket traction, modified Nance arch traction, and anchorage screw traction, etc.

[0003] The above-mentioned traction methods have the following problems:

[0004] Brackets need to be bonded to other teeth in the oral cavity and arch wires need to be placed, which are likely to cause ulcers and pain, and the comfort level is relatively low. Moreover, the brackets are prone to falling off and the arch wires are prone to piercing, bringing inconvenience to the patient's life and aesthetics.

[0005] In addition, due to its high comfort and high precision, invisible orthodontic appliances are increasingly favored by orthodontic patients. However, invisible orthodontic appliances need to wrap the teeth with a membrane to achieve tooth movement. Therefore, the current invisible orthodontic appliances cannot play the role of traction for impacted teeth, and the aforementioned conventional impacted tooth traction methods and tools cannot achieve the functions of the beauty and comfort of invisible orthodontic appliances and tooth alignment.

[0006] Therefore, it is necessary to design a device that can achieve impacted tooth traction while wearing an invisible orthodontic appliance for tooth alignment in the dental arch. Content of the Utility Model
