HEMPEL SOUPER, Germán; SAT YABER, María Ignacia; VARGAS AGUILAR, Valeria  y  DIAZ MUNOZ, Alejandro. Evidence-based comparison of self-ligating and conventional brackets. Odontoestomatología [online]. 2021, vol.23, n.38, e302.  Epub 30-Sep-2021. ISSN 0797-0374.

Self-ligating brackets include a locking mechanism that holds the archwire in the bracket slot. They were created primarily to create a lower friction system, allowing for more efficient sliding mechanics and reducing treatment time.


This review aims to present all the information available on different self-ligating devices, whether active or passive, in a structured and organized way. This paper sets out to compare their qualities with each other and with conventional devices.


A search was conducted in PubMed and Epistemonikos, regardless of language or year of publication.


Comparisons were made of both active and passive self-ligating brackets and self-ligating brackets with conventional brackets in different clinical situations.


No statistically significant difference was found in most clinical situations, except for torque expression, where conventional brackets have a more significant advantage.

Palabras clave : Orthodontic brackets; Self-ligating brackets; Conventional brackets.
