Table 3 Accuracy of premolar derotation according to the amount of planned tooth movement

From: Treatment outcome and efficacy of an aligner technique – regarding incisor torque, premolar derotation and molar distalization

Planned movement Mean accuracy (%) Highest accuracy (%) Lowest accuracy (%) Mean standard deviation
Premolar Derotation < 15° 43.3 72.5 16.8 0.24
Premolar Derotation > 15° 23.6 76.9 -2.9 0.15
