Implication

Finite element analysis evaluates the impact of attachment shapes and positions on tooth movement in clear aligner therapy, indicating potential clinical recommendations.

Key Points

The highest tooth displacement of 0.013 mm was recorded with a horizontal beveled rectangular attachment.
Von Mises stress reached 0.021 MPa in the same model, demonstrating effective stress distribution in the PDL.
Models with attachments consistently showed greater tooth movement compared to those without attachments.
The study suggests that specific attachment designs can enhance the efficiency of molar derotation in orthodontic treatment.
