Correction of the curve of spee using clear aligner therapy: A finite element analysis of three lower anterior intrusion protocols

Key Points

• Simultaneous intrusion of canines and incisors effectively corrects the Curve of Spee.
• This biomechanically efficient method minimizes stress and related side effects in orthodontic treatment.
• Analysis focuses on three protocols for lower anterior intrusion using clear aligner therapy.
• Careful treatment planning is crucial for managing anchorage control and secondary movements.
