In orthodontics, how do you control tooth movement torque to prevent unwanted root tipping?

• A. Ignore torque during treatment and rely on esthetics.
• B. Use bracket prescription and precise wire sequencing; apply torque with archwires and consider torque accessories; monitor with periodic radiographs.
• C. Use elastics only.
• D. Adjust torque randomly.

Answer: (B)

Torque control is about delivering a deliberate twisting force to the tooth so the root moves in concert with the crown, preventing unwanted tipping as teeth move. The best way to achieve this is by combining a bracket prescription that provides the desired initial root orientation with precise wire sequencing that progressively engages torque. Rectangular archwires deliver a stronger torque moment when they fill the slot, and torque accessories or bends can augment this control, guiding the roots while the crowns align. Periodic radiographs let you verify root positions during treatment and adjust mechanics early if tipping tendencies appear.

Skipping torque, or relying only on aesthetics, won’t manage root inclination. Elastics mainly influence vertical or horizontal alignment and bite without giving reliable root torque. Random or unfocused torque adjustments are unpredictable and can worsen root angulation.
