Which is the main purpose of using elastic chains in orthodontics?

The main purpose of using elastic chains in orthodontics is to close spaces between teeth. Elastic chains are utilized to apply continuous pressure on the teeth, facilitating the movement required to close gaps effectively. This is particularly useful in cases where a tooth has been extracted or when spaces exist due to developmental issues.

The design of these chains allows for a consistent force to be exerted over time, which is essential in orthodontic treatment to achieve desired tooth positioning. This method is efficient in reducing the duration of treatment by gradually moving the teeth into their proper alignment, ultimately leading to improved occlusion and esthetics.

In contrast, while elastic chains may support brackets or hold arch wires in place, their primary role is not centered around these functions. Adjustments in orthodontics typically involve changes to the arch wire or other components of the appliance rather than the elastic chains themselves. Understanding the specific purpose of elastic chains highlights their critical role in the overall orthodontic treatment plan.
