A complication with orthodontic fixed retainers: a case report

Abstract

Fixed retainers are a popular method of maintaining incisor position following orthodontic treatment. This paper reviews the complications reported with fixed retainers and reports a case in which suspected activation in a multistrand bonded retainer had caused severe unwanted movement of two teeth in the upper labial segment. Clinical Relevance: This paper stresses the importance of passive fixed retainers and the need for long-term review of patients wearing bonded retainers.
