Retention begins when orthodontic treatment is completed. Retention is the phase of treatment responsible for keeping the teeth straight after the active phase of orthodontic treatment is completed.
The human body is a biological environment that is constantly undergoing change and the teeth are also subject to these changes. The forces acting on teeth alter over time, which leads to tooth movement. Retention is carefully planned with the full awareness that these biological changes will occur and attempt to minimise the effects and maintain the gratifying orthodontic treatment outcome.
The gold standard of orthodontic retention is a thin metal wire glued to the back of the front teeth and a plastic retainer for night time wear. The wire is not visible and is very comfortable. The new zig-zag design improves the oral hygiene and the ability to floss.
