The aim of this article is to show the effectiveness of Vivera retainers (Align Technology, San Jose, CA, USA) after orthodontic treatment to favour long-term stability. Vivera retainers are produced as a final retainer option following nearly invisible orthodontic treatment (Invisalign, Align Technology). The use of removable plastic appliances is currently gaining popularity among orthodontists thanks to their ability to encapsulate and retain both posterior and anterior teeth. However, traditional thermoformed appliances display some limitations regarding wear resistance and fitting. This article describes the technical features of Vivera retainers and presents a clinical case with a 10-year follow-up to emphasise the effectiveness of Vivera retainers.
