INTRODUCTION: The V-loop bonded lingual retainer is an innovative design that allows the patient to floss with ease, a significant advantage over the conventional straight wire design for interproximal plaque control. The aim of this retrospective study was to compare the efficacy of straight wire and V-loop fixed retainers with respect to detachment rate when used to stabilize maxillary or mandibular anterior teeth after orthodontic treatment. METHODS: Fixed, customized retainers were placed in 300 patients and followed for 6 months. The conventional retainer system was a .0175-in stainless steel multi-stranded wire placed as a straight, bonded lingual retainer. The newer system was a .016-in stainless steel black Australian wire placed in a V-loop design. RESULTS: The detachment rates were 14.3% for the V-loop design and 12.4% for the straight wire retainer. The difference was not statistically significant. CONCLUSIONS: The V-loop retainer system addresses cleanability and physiologic adaptability, both critical for the clinical success of bonded lingual retainers used for long-term retention. The interdental wire span of the V-loop design allows easier access for flossing and sufficient flexibility for independent tooth movement in the periodontal space. Patient acceptance of the V-loop bonded lingual retainer was excellent, and most patients in this study found the retainer comfortable and easy to floss.
