What does a second order bend aim to provide?

torque
position teeth in proper horizontal buccolingual position
provide proper angulation
center of rotation

The correct answer is: provide proper angulation

A second order bend in orthodontics refers to the angulation of the wire to properly align the teeth in the desired position. Torque (A) refers to the force applied to rotate a tooth, which is different from angulation. Positioning the teeth in proper horizontal buccolingual position (B) is important, but it is not specific to a second order bend. Center of rotation (D) refers to the point around which the tooth moves during orthodontic treatment, which is also not specific to a second order bend. Therefore, the correct answer is C provide proper angulation.
