1) Round
2) Square
3) Rectangular
4) All of the above

Answer 1

Round arch wire would not be used to position the crown and root of the teeth in the final stages of treatment.

Step-by-step explanation:

The type of arch wire that would not be used to position the crown and root of the teeth in the final stages of treatment is Round. Round arch wires are usually used at the beginning of orthodontic treatment to level and align the teeth, but they are not ideal for final positioning because they do not provide as much control over individual tooth movements as other wire types.
