Biomechanical effects of different staging and attachment designs in maxillary molar distalization with clear aligner: a finite element study

ConclusionsA step distance of moving two molars to 0.130  mm can achieve the same reaction force on the anterior teeth as moving one molar 0.250 mm without effects on horizontal or vertical rectangular attachments.Clinical relevanceOur results provide a theoretical basis and guidance for simultaneously moving two molars backward in clinical practice using a clear aligner.
