What are the advantages and disadvantages of a clear retainer?

With the advent of new, clear plastic materials in orthodontics, patients can benefit from more aesthetic options during the retention phase of orthodontic treatment. Clear retainers are comfortable, aesthetic, and require no adjustment. However, they can be severely worn or broken if subjected to heavy biting forces. In our office, patients receive clear retainers as a backup retainer and for social convenience during the first 3-6 months. If the Hawley retainer is lost or broken, the clear retainer can be used as a backup, while our lab fabricates a new Hawley retainer.
