| Introduction Clear aligner therapy (CAT) is one of the treatment methods that orthodontists use to treat different malocclusions. Initially, CAT was recommended for mild malocclusions, such as minor crowding, slight spacing, buccolingual tipping of teeth, and arch expansion. However, with the growing demand for and popularity of CAT and advancements in biomechanics, many orthodontists are now using CAT to treat more complex cases, including extraction cases, severe crowding, distalization, and surgical cases. The effectiveness of CAT is influenced by various factors, such as the complexity of the required tooth movements, the patient’s level of compliance with wearing the aligners as prescribed, and the orthodontist’s expertise. The quality of the aligner material and the precision of the treatment planning process can also impact the success of CAT. Despite the increasing popularity of CAT aligners provided by different companies, data in the literature remain limited regarding their predictability. Aim The aim of this article is to review the available data in the literature regarding the accuracy of CAT in achieving different tooth movements. Conclusion The predictability of tooth movement by CAT is multifactorial and depends on the type of tooth movement, the patient's compliance, and the orthodontist's experience. The recent advances in the biomechanics of CAT have improved the accuracy of its outcome. Buccolingual tipping is the most accurate movement when using CAT. Severe spaces (≥6 mm) have significantly lower predictability than mild spaces. CAT is more predictable in treating open bite by extrusion of the incisors and intrusion of the molars. | ||||
