Round wires in orthodontics are typically used for what purpose?

In orthodontics, round wires primarily serve the role of facilitating initial movement and addressing intermediate corrections of crowding. These wires are designed to be flexible, which allows them to apply an appropriate amount of force to the teeth as they are gradually shifted into more desirable positions. This initial phase is essential for aligning teeth properly before more rigid wire options are used to achieve final adjustments.

The nature of round wires also makes them effective in creating a gentle, continuous force, which is crucial for the delicate process of moving teeth. As the treatment progresses, orthodontists may switch to rectangular wires for final alignment or to create the desired arch form, as these provide more control and are better suited for precise adjustments. Therefore, the use of round wires is particularly advantageous during the earlier stages of orthodontic treatment for managing crowding and facilitating initial movement.
