Abstract: The plastic aligner is favored by many doctors and patients due to its advantages of aesthetics and comfort. Due to the particularity of correction force loading, its clinical indications are relatively narrow. How to solve the problem of overall tooth movement is the most important task to broaden the indications. However, there is a lack of systematic research on the root control movement at present. This paper will summarize relevant studies on the basis of overall biomechanics of movement, the types of root control attachment and the optimization measures, so as to provide a reference for the plastic aligner in clinical practice.
