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

Abstract

VLPPP generated the highest force output, but also induced the greatest biological stress. In contrast, VLP with dual surface attachments effectively facilitated tooth movement while minimizing biological stress. Multi-surface force application enhances biomechanical control in clear aligner canine derotation.
