Relapse Clinical Trial
Official title:
"Comparison of Retention Characteristics of Immediate vs Delayed Retainer Delivery Using 3 Dimensional Digital Model Analysis : A Prospective Clinical Trial "
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.The present randomised controlled trial will be undertaken to assess the changes and compare if there is any difference in movement of teeth in post orthodontic treatment cases with immediate and delayed (post 7 days) delivery using beggs retainer and change in level of bone biomarker over 6 months period of retention .
