What holds dental arch wires securely in place during orthodontic treatment?

Ligature ties and elastomeric ties are specifically designed to hold dental arch wires securely in place during orthodontic treatment. These ties come in various materials, including stainless steel and elastic, and are essential for maintaining the correct positioning of the arch wires within the brackets attached to the teeth.

Ligature ties generally consist of thin, flexible wires that are wrapped around the bracket and the arch wire, providing a snug and secure fit. Elastomeric ties, on the other hand, are made of rubber-like material, which allows for easy application and removal while still effectively securing the arch wire. The use of these ties is critical to ensure that the forces applied by the arch wire are directed appropriately to achieve the desired tooth movement.

The other options do not serve this purpose. Cement is utilized for bonding brackets to the teeth but does not hold the arch wires. Temporary crowns are used in restorative procedures and do not relate to orthodontic wire management, and composite resin is used primarily for fillings or bonding but is not involved in securing arch wires within orthodontic treatment.
