The aim of the study is to evaluate the long termudresults of ribbond retainer after orthodontic treatment. One hundred and thirty patients who were orthodontically treated satisfied the inclusion criteria of having received a semipermanent retention were treated with FRC lingual retainers (Ribbond®). It was performed a follow up evaluation after 2 years average from the retainer application and any complication or failure was recorded. udData from 119 remaining patients that met the inclusion criteria were analyzed and no instances of loosening were observed. It may be concluded that orthodontic udcanine-to-canine FRC retainers provide aneffective means of retaining realigned anterior teeth for at least two years.
