Ambulator-tooth traction device: after the ambulator-tooth is exposed through flap bone removal, one end of the device adheres to the tooth surface, and the other end is ligated on the nickel-titanium main bow wire or auxiliary bow wire, or the bow wire passes through the chain hole.

Advantages: 1. Strong tooth surface adhesion, not easy to fall off.2. Adjust the strength through the length of the chain.The strength of the rubber chain tends to decay.The metal chain is not easy to damage.Soft tissue resistance is low.5. Easy to clean.
