The aim of this study was to evaluate and compare the costs for the three orthodontic retention methods using a cost-minimisation analysis (CMA). The cost analysis was based on previous randomised controlled trial data (Dental Elf 22nd Jan 2013). Patients were randomised into 3 groups with retention appliances being placed within 1 hour of debonding.  [read the full story…]

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…]

Long -term retention is necessary to avoid relapse following the completion of orthodontic treatment. The lingual retainer can be a useful method of retention. The aim of this study was to investigate the effect of liquid resin on the survival of fixed lingual retainers and to evaluate the incidence of calculus accumulation and discoloration adjacent [read the full story…]

Long term studies have shown that relapse occurs  in around 70%  of  orthodontic treatment.  However it is difficult to predict either those cases that will relapse or the degree to which it will occur. The aim of the this study was to compare the effectiveness of vacuum-formed and Hawley retainers in maintaining arch width as [read the full story…]
