Retention is an essential phase of orthodontic treatment without which there is a tendency for teeth to return to their initial position. The aim of this review was to compare the effects of Hawley retainers (HRs) and vacuum-formed retainers (VFRs) Searches were conducted in Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, ISI Web [read the full story…]

No randomised controlled trial evidence on effective methods to treat relapse of lower front teeth following orthodontic treatment


The tendency for teeth to return to their pre-treatment following orthodontic treatment (relapse) is more common for the lower front teeth.  Ten years after orthodontic treatment between 30-50% of patients no longer have the initial post-treatment alignment and after 20 years only 10% maintain that alignment. The aim of this review was to assess the [read the full story…]

No difference in survival of mandibular lingual orthodontic retainers placed with chemically and light-cured adhesives


Long-term stability following orthodontic treatment required long-term retention. Compliance with removable retention regimens is variable so some practitioners favour fixed retainers.  The aim of this study was to compare the survival of mandibular lingual retainers placed using either chemical or photo polymerization after orthodontic treatment. Patients who had completed orthodontic treatment with no active caries, [read the full story…]

Trial found little difference between three post orthodontic retention methods

Following orthodontic treatment almost every patient will require a period of retention without which there is a tendency for teeth to return to their initial position.  The aim of this trial was to compare three different retention methods. Patient s completing a first course of orthodontic treatment were randomized into three retention methods: vacuum-formed retainer [read the full story…]
