Résumé

Depuis leur apparition, les systèmes auto-ligaturants ont fait l’objet de nombreuses études. Celles-ci ont permis de mettre en exergue les multiples avantages d’un traitement réalisé à l’aide des brackets auto-ligaturants, en comparaison avec un traitement avec des brackets classiques.

Parmi ceux-ci, ont été essentiellement avancés : une moindre résistance au glissement, une mise en place de l’arc et sa dépose plus rapides, un engagement total de l’arc ainsi qu’une diminution de la douleur ressentie par le patient.

Néanmoins, la réalisation d’autres travaux est nécessaire afin d’asseoir définitivement leur supériorité sur les brackets classiques.

Abstract

Since an early stage in the development of self-ligating brackets, authors have proposed advantages in relation to treatment efficiency. Increased efficiency can be defined as achieving a result that is as good or better, with an increase in factors that are valued by the provider or the recipient of a service. In orthodontic treatment, these factors could include fewer appointments, shorter appointments, more comfortable treatment, practical procedures that are technically easier for the clinician or the patient, less need for extractions, and less pain or anxiety for the patient. There could also be factors relating to outcome, such as less decalcification or root resorption, and more certain or better results. All of these have been proposed by some authors in relation to self-ligation. The core assets of self-ligation, which form the basis of any such proposal, can be summarized as follows: secure, full archwire engagement; lower resistance to sliding between bracket and archwire; faster ligation and archwire removal; and less need for chair-side assistance.
