What is the difference between thick steel wire and thin steel wire used in orthodontics?

It is normal to use thick steel wire and thin steel wire when correcting teeth. Thin steel wire is used in the initial stage of correction and can be used to forcibly correct the shape of teeth. Later, the shape was fixed with thick steel wire to keep the shape of teeth.

When fixed orthodontics is used to correct teeth, it is necessary to apply force to the arch wire, transmit it to the teeth, and drag the teeth to the target position. The arch wires include nickel-titanium round wires (5 groups), nickel-titanium square wires (4 groups), Australian wires (2 groups), stainless steel round wires (2 groups) and stainless steel square wires (2 groups). Usually, the diameter of arch wire changes from thin to thick. After 4-6 weeks, all the teeth in the last group are aligned, and the arch wire can be replaced without resistance in the bracket, which needs to be replaced about 15- 16 times. The principle of wire orthodontics is to attach and fix metal, ceramic brackets, buccal tubes and other accessories to the labial side of teeth. After the Ni-Ti archwire is ligated and fixed, the traction force is generated by the superelasticity of the archwire, so that the alveolar bone around the root changes, one side of the alveolar bone is absorbed, and the other side is deposited to form new bone, thus making the teeth move gradually. After the teeth are arranged neatly, slowly close the gap, adjust the occlusal relationship between the upper and lower teeth, and finally achieve relatively extensive contact with the cusp fossa. After the correction is completed, remove the appliance and put on the retainer to prevent the teeth from rebounding and shifting.
