What shape of arch wire is indicated for correcting malaligned teeth?

  1. Circular wire

  2. Square wire

  3. Rectangular wire

  4. Triangular wire

The correct answer is: Rectangular wire

Rectangular wire is indicated for correcting malaligned teeth because it provides more control and precision in guiding the teeth to their desired positions. Circular wire is not recommended because it does not provide enough control and can lead to less predictable outcomes. Square and triangular wires are also not recommended as they do not have the same level of precision as rectangular wire. They may also cause discomfort for the patient and can take longer to achieve the desired results.
