Plier Arch Bending, Arched Lingual

The Plier Arch Bending, Arched Lingual 678-309 is an orthodontic instrument specifically designed for creating precise bends in lingual arch wires. Here are the uses based on various sources:

1. Creating Bends in Wires: It is used to create double back and triple back bends in lingual arch wires. These types of bends are crucial for adjusting the wire to the correct shape and position along the lingual side (the side of the teeth that faces the tongue) of the dental arch​​​​.

2. Accommodating Various Wire Sizes: The plier is capable of handling lingual arch wires up to .036" (.91 mm) in diameter. This allows for a range of wire sizes to be manipulated, providing orthodontists with the versatility needed for different treatment requirements​​​​.

These pliers are an integral tool in the practice of orthodontics, aiding in the formation of complex wire shapes required for the individualized treatment of patients.
