A Tie Wire (also called a Wire Ligature or Metal Ligature) is a thin metal wire used in place of an elastic ligature. It is tied and twisted over the arch wire and around the braces bracket. Orthodontists might use a tie wires instead of an elastic ligature to try to move a tooth faster or to hold spaces together after using a power chain.
