Dental distalization techniques with clear aligners: a narrative review

Abstract

Clear aligners (CAs) have revolutionized orthodontic care, offering aesthetically pleasing, comfortable, and practical solutions for correcting malocclusions. Among their various applications, dental distalization, a crucial movement for treating Class II malocclusions and managing dental crowding, has become a focus of modern orthodontics. This review synthesizes evidence on the predictability of distalization using CAs, highlighting their benefits, challenges, and advancements. Research indicates that aligners achieve distal molar movement with an accuracy of approximately 70%, dependent on factors such as patient adherence, technological advancements, and auxiliary tools like temporary anchorage devices (TADs). Despite these advancements, challenges like insufficient control over transverse movements remain. Future innovations integrating artificial intelligence and enhanced digital planning tools offer promising prospects for improving outcomes and expanding the capabilities of aligner therapy.
