What are elastics used for in orthodontics?

Elastics in orthodontics serve a specific purpose. They are primarily used to connect different components of the orthodontic appliance and are crucial for providing the necessary force to move teeth into the desired positions. The correct function of elastics relates to their role in creating coordinated movement within the dental arch and aligning teeth properly.

When it comes to connecting the archwire to the tooth, elastics help to maintain tension, allowing the movement facilitated by the archwire to take effect. They are placed over brackets or bands and enhance the overall effectiveness of the orthodontic treatment by ensuring everything works together harmoniously.

In terms of securing bands or brackets, while bands might be held in place primarily by adhesive and not elastics, elastics do indeed contribute to keeping the brackets functioning effectively during treatment by ensuring proper alignment and facilitating the movement of teeth more reliably. Thus, while primarily associated with connecting components, their overall function in an appliance system is crucial in supporting teeth movement.
