Evaluating the impact of attachment designs on canine derotation in clear aligner therapy: a finite element analysis

Key Points

• This research aims to evaluate how different attachment designs influence canine tooth derotation during clear aligner therapy.
• Used finite element analysis to simulate attachment designs
• Compared force outputs of VLPPP and VLP designs
• Assessed biological stress and tooth movement efficiency
• VLPPP generated the highest force but also increased biological stress
• VLP with dual surface attachments effectively facilitated tooth movement with reduced stress
• Multi-surface force application improves biomechanical control in canine derotation
