Brief Summary

After orthodontic treatment, relapse is inevitable and is defined as a movement towards the initial state which is undesirable. To prevent relapse, a phase of retention is required. Retention has been defined as "the holding of teeth following orthodontic treatment in the treated position for the period of time necessary for the maintenance of the result". Controversies regarding retention regime exist due to lack of high quality evidence regarding duration, type and timing of different type retainer. There is an unusual delay after debonding in retainer delivery as the retainer is fabricated at the laboratory. Such the present study will help us to find out within which time period the retainer should be delivered.
