A third order bend is used to?

  1. tipping

  2. torque

  3. center of rotation

  4. torque teeth in buccolingual direction

The correct answer is: torque teeth in buccolingual direction

A third order bend is used to torque teeth in the buccolingual direction. When adjusting orthodontic wires, a third order bend is applied to produce controlled rotational movement of the tooth around its long axis. This bend helps to address any buccolingual or lingual root torque discrepancies and align the teeth properly within the dental arch. The other options are not correct as they do not refer to the specific purpose of a third order bend in orthodontic treatment.
