The Invisalign system has been used in the clinic for nearly two decades and its invisible, comfortable and beautiful features are increasingly favored by doctors and patients. In recent years, Invisalign technology is constant⁃ ly innovating from mild crowding (G1), relatively complicated tooth movement (G2), anterior tooth torque control (G3), anterior open bite (G4), deep overbite (G5), first four premolar extraction (G6), and posterior open bite (G7) to the correc⁃ tion of skeletal class Ⅱmalocclusion in adolescents. Its indications has covered almost all areas of traditional fixed or⁃ thodontics. However, as this technology is in the developmental stage, there is a discontinuity between the computer⁃de⁃ signed positioning and the clinical results. Although Invisalign has manifested excellent performance in correcting tooth intrusion, tipping movement and distal movement, its ability to correct tooth rotation and extrusion still needs improve⁃ ment. This paper reviews the characteristics of Invisalign G1⁃G7 and Invisalign MA and the efficacy of these systems in correcting different types of tooth movement.
