An alternative for postorthodontic labial retention in an unusual case.

An integral part of sustaining long-term orthodontic results is a lingually bonded retainer. These retainers have been established as a standard retention protocol, as they combine efficiency and esthetics. Increasing patient demands for improved esthetics and maintenance of good health of dental and periodontal tissues have led to the development of new techniques and materials involving reinforced polyethylene fibers. In this case report, retention featuring the use of a reinforced polyethylene fiber retainer, placed labially to avoid irritating the tongue, is presented. Three-year posttreatment records indicated no relapse and that the integrity of soft and hard tissues had remained intact.
