These suspension fibers, similar to thick rubber bands, can stretch and twist as teeth are moved. However, this elastic property changes slowly. Even if teeth are moved rapidly into place, these fibers can get stretched or twisted, and their elasticity can persist. If no force is applied to them, these fibers may gradually return to their original state, moving the teeth back to their initial positions.

Orthodontic elastic chains are a commonly used orthodontic accessory, utilized in clinical practice for traction, correcting rotations, closing extraction spaces, and closing scattered gaps. They are simple to use and hence widely applied in clinical settings. So, how should we choose and use orthodontic elastic chains in daily practice? Today, we'll discuss these two aspects.

Brackets are important components of fixed teeth orthodontic technology, which are directly bonded to the surface of the dental crown with adhesive. The deformed archwire applies various types of orthodontic forces to the teeth through the bracket, thereby moving the teeth and achieving the effect of orthodontic treatment.
