During fixed orthodontic treatment, ligation is used to keep the arch wire in the slot of the bracket. It can also be used to move the tooth in a particular direction depending upon the type of ligature used and its method of ligation. Ligation can be done using Stainless steel (SS) ligatures or elastomeric modules. SS ligature wire provides secured tie of arch wire to bracket slot, lesser friction and slower rate of force decay compared to elastomeric modules. Elastomeric modules are easier to place and take lesser chair side time. Elastic ligature does not have sharp edges and they exert lesser force on the bracket. So, they are preferred in those situations where there is higher tendency for debonding of brackets. Elastic ligature may be a substitute for the wire ligatures in most situations. In various treatment mechanics ligation ties are modified to accomplish variable tooth movement or to maintain arch form integrity during finishing of an orthodontic case. This article will highlight different ligation ties used in different bracket systems and their indications as well.
