What is the primary function of the archwire in orthodontic appliances?

The primary function of the archwire in orthodontic appliances is to serve as a guiding mechanism that applies forces to the teeth. The archwire connects the brackets that are bonded to the teeth, creating a continuous pathway for the application of orthodontic forces. These forces are crucial for moving the teeth into their desired positions over time.

The archwire is designed to be flexible yet strong enough to exert the necessary pressure, working in conjunction with the brackets and elastic bands to ensure controlled movement. By manipulating the positioning and configuration of the archwire, an orthodontist can effectively guide the alignment of the teeth, making it an essential component of any orthodontic treatment plan.
