CONTAINMENTS USED IN ORTHODONTICS AND THEIR RELATIONSHIP WITH OCCLUSAL STABILITY OVER THE TIME

Francisca Keith Álvarez, Andrés Santoni Lavarello, Aldo Véliz Zapata

Abstract


One of the great challenges for the orthodontist is to keep the teeth in their correct position after the active phase of the
treatment, since it is described that, without retention, there is a tendency for the teeth to return to their initial position,
called recurrence. In this document we review the scientific evidence on the function of the different types of posttreatment
retainers, in addition to describing their efficacy and results.
Publications were searched from 2010 and with a follow-up of at least 6 months. The lack of protocols was observed as to
what type of retainer to use and its time of use, and evidence of failure rates was found in all types of retainers.
Currently, there is not enough scientific evidence on what is the best type of retention protocol.
