Since the commencement of this orthodontic specialty, it is a grueling and portentous task to maintain the orthodontically treated teeth in their corrected and desired position. Retention of what has been achieved is the goal and the most clamant phase of any orthodontic treatment as well as the orthodontist. To maintain the stomatognathic system’s esthetics, function, and stability, orthodontic retainers play a vital role in precluding post-treatment tooth movement. The predetermination of retention goals is critical to that achieved while accomplishing the biomechanical objectives of dentoskeletal movements. The overall success of the orthodontic treatment is contributed by the compliance of the patient, diurnal oral hygiene maintenance, durability and effectiveness of the appliance that has been worn, and routine follow-up visits and generalized oral health of the patient. As a trend of suggesting lifetime usage of retainers is important, imperceptible and visually beautiful vacuum-formed retainers have gained significant popularity. In this rising period of an individual being more confident, aesthetically pleasant appliances are a treatment of choice.
