How do you tie an orthodontic ligature wire to hold an arch wire in place?

To tie an orthodontic ligature wire to hold an arch wire in place, first, cut a length of ligature wire about 5-7 cm long. Using a ligature tie tool or tweezers, wrap the wire around the bracket and the arch wire, making sure it secures the arch wire firmly in the bracket slot. Twist the ends of the ligature wire together to secure it, ensuring it is snug but not overly tight to avoid damaging the bracket or arch wire. Finally, trim any excess wire to prevent irritation to the patient's cheeks.
