Abstract: The birth of clear aligner technique (CAT) has satisfied people’s need for aesthetic and comfort orthodontics. At present, CAT has been widely used in clinic and become a good method for adults and adolescents. At the beginning, the clear aligners could only be used for simple orthodontic treatment, such as aligning the dentition. However, with the constant study of clear aligner manufacturers and the clinicians, the clear aligner technique has been improved and gradually refined, in which the premolar extraction treatment tends to mature. This article reviews the anchorage design and clinical control of premolar extraction treatment with the clear aligner technique.

Key words: clear aligner technique, premolar extraction, anchorage design, clinical control
