Introduction: Clear aligners have emerged in the field of Orthodontics in an attempt to change the face of Orthodontics. With the increased awareness of aligner treatment options, it is important that the present day Orthodontist is well aware of the biomechanics and limitations of the same. The growth of aligners in the field of Orthodontics has made it vital that Orthodontists are well versed with the workflow of aligners and are able to successfully treat at least mild to moderate malocclusions. Aim and Objective: The aim of this study was to evaluate the knowledge, awareness and attitude about clear aligner therapy amongst post-graduate orthodontic students. Materials and Method: A google form questionnaire of 18 questions were designed and distributed amongst 120 Orthodontic post-graduate students via WhatsApp messenger and email. The responses were recorded, organised and evaluated. Results: Students were aware of the type of tooth movement exerted with clear aligners, materials used, workflow, anchorage system, types of attachments used in clear aligner therapy. However, they were unaware of the tooth movement caused by power ridges, placement of precision bite ramps and order of staging in terms of distalization. Majority of the students agreed that clear aligners have a definite aesthetic advantage over other modalities of treatment. Conclusion: There is adequate knowledge and awareness about clear aligner therapy amongst Orthodontic post-graduate students.
