What is the movement of torque in orthodontics?

Mesio-distal
Buccal-lingual
Vertical
Occlusal

The correct answer is: Buccal-lingual

The movement of torque in orthodontics refers to the rotational force applied to a tooth which influences its long axis. This motion is specifically characterized by a buccal-lingual movement—where the tooth can be rotated towards the buccal (the cheek side) or lingual (the tongue side). Torque allows orthodontic devices, such as brackets and wires, to treat the tooth's angulation and improve its alignment within the dental arch. This functional aspect of torque is essential for achieving desired treatment outcomes, such as correcting anterior tooth angulation or addressing a deep bite. Understanding this movement is crucial for orthodontic assistants as it helps them comprehend how adjustments to appliances can lead to more effective tooth positioning and alignment over time.
