Orthodontic treatment goals can be expressed as achieving ideal tooth alignment, esthetic, functional occlusion and stability. Various occlusal changes occur after active phase of orthodontic treatment, these unwanted changes are called relapse. Reitan pointed out that major percentage of changes following active phase of treatment is seen within 24 hours. To alleviate the effect of relapse, retention is needed. There is little agreement among clinicians about orthodontic retention protocol due to insufficient evidence in the literature on 1. time of retainer delivery 2. unexpected post- treatment changes. 3.quantification of relapse tendency. The present study will be undertaken to assess the changes and compare if there is any difference in the movement of teeth in post orthodontic treatment cases with immediate and delayed (post 24 hours) retainer delivery. Thus help in deciding when should the retainer delivery is preffered.
