Abstract

Using stainless steel auxiliary ligatures in conjunction with fixed orthodontic appliances is of paramount importance in many stages of orthodontic treatment. There is a lack of articles in the literature that provides a comprehensive review of the uses of different methods of ligation in orthodontic treatment. The aim of this article is to provide an illustrated review of their use with fixed appliances; moreover, it will provide practical tips for their appropriate use.

CPD/Clinical Relevance: This article aims to provide a review, with detailed illustration, of the use of stainless steel ligatures in orthodontic treatment.

Article

Orthodontic techniques have evolved significantly over the past three decades. The use of stainless steel auxiliary ligatures with fixed orthodontic appliances contributes significantly to the efficiency and the effectiveness of tooth movement, largely due to the so-called frictionless or low-friction mechanics,1,2,3 much more effective engagement of the archwire into the bracket slot and the advantage of being a much less plaque retentivearrangement.4,5

Elastomeric modules are by far the most popular method of ligation of archwires; they are preformed, convenient and allow rapid archwire engagement, yet they have disadvantages: mainly saliva/bacteria absorption causing reduced effectiveness with time, and limited elastic properties that sometimes compromise full archwireengagement.6

The uses of stainless steel ligatures with fixed appliances include the following:
