Abstract:

In recent years, clear aligners have been widely employed in clinical treatment because of its esthetics and comfort. However, due to the complexity and unpredictability of tooth movement, the preset displacement cannot be fully achieved. And the efficiency varies with types of movement. Hence overcorrection is applied in clear aligners to enhance the efficiency. This article reviews the application of overcorrection design in arch expansion, intrusion, derotation, and extraction cases with clear aligners and provides reference for clinical practice.

Key words: clear aligner, overcorrection, tooth movement efficiency, application
