This paper focuses on adolescent orthodontic treatment. It should be stressed that a retainer appliance, of whatever sort, is only useful once the planned result, and especially the occlusal objective, has been achieved. A review of Tweed technique objectives is also presented.
Prognosis depends on quality of finishing, acquisition of normal function and neuro-muscular adaptation, to minimize risk of relapse. Nonetheless, relapse seems inevitable in the long term as regards individual crowding, except if retention is maintained for a very long time. Many clinical situations, in different pathologies and with 5 to 22 years’ follow-up after active treatment will be described illustrate progress in retention strategy, as it is difficult to assess real stability after only 1 year's retention, as can be seen from the orthodontic literature.
Key words: Retention / prognosis / stability / relapse / occlusion / treatment goals
