Abstract

Abstract: There is a growing amount of literature describing the benefits of self-ligating brackets; one such benefit is their low friction properties. A clinical case is described in which dental extractions were avoided to alleviate severe crowding and the conclusion is drawn that this may, in part, have been due to the decreased friction in the orthodontic appliance afforded by the use of self-ligating brackets.

CPD/Clinical Relevance: This article discusses the benefits of self-ligating brackets and describes a clinical case in which, potentially, the low friction properties of self-ligating brackets helped avoid dental extractions.

Article

The first self-ligating bracket (SLB) was described by Stolzenberg in the 1930s1 and introduced as the Russell lock edgewise attachment. The concept of the SLB has not changed much since that introduction. However, the use of the design has become much more mainstream in the last three decades, so much so that the success of the Damon type bracket is almost synonymous with a form of treatment. Due to this growing demand from both the orthodontist and the patient, many new bracket types have been described. These are all based around having a spring clip which ‘locks’ the archwire in position, ie excluding the use of elastics or wire ligatures. These brackets can further be subdivided into their ‘active’ or ‘passive’ variants. The active form has a spring clip which presses against the archwire and in the passive form the clip does not come into contact with the archwire.
