Orthodontic treatment stability is a major concern for the orthodontist. Which orthodontist has never had the displeasure of assessing a case over the retention phase and inding out that formerly well-positioned teeth are now rotated or have diastema? In the attempt to prevent relapse, the orthodontic literature recommends that retention, whether removable or ixed, be used for a certain period of time. Fixed retainers installed in all teeth are advantageous because they do not rely on patient’s compliance. On the other hand, they favor bacterial plaque which, in turn, may lead to tooth caries and periodontal damage. They might be spiralwire or iber-reinforced retainers. In this context, the following question arises: Which ixed retainer elicits less detrimental periodontal response? Iranian researchers1 conducted a study to assess the periodontal efects of two diferent retainers: spiral-wire and iberreinforced. Results revealed that spiral-wire retainers elicit less detrimental periodontal response than iberreinforced ones within a short period of 6 months. The authors highlight that radiographic assessment of both retainers did not reveal statistically signiicant and conclusive diferences.
