Abstract:

Clear aligner technique has developed rapidly in the past few years. Patients prefer clear aligners because of superior esthetics and comfort, while the effectiveness and stability of anchorage control in clear aligners are still controversial. Molar mesial tipping and anchorage loss are easy to manifest in clinical treatment. This article reviews recent published studies based on six factors including posterior teeth anchorage preparation, anterior teeth intrusion overtreatment, tooth movement pattern, intermaxillary traction,intramaxillary traction and vertical facial type. The review aims to provide reference for clinical treatment design.

Key words: clear aligner, extraction case, anchorage control, research advance
