Maxillary arch expansion in different dentition stages using clear aligners: a three-dimensional finite element analysis
The efficacy and biomechanics of CA maxillary expansion differ by different dentition stages in adolescent patients. In mixed dentition, expansion mainly occurs at the mid-arch, with palatal molar displacement and labial incisor tipping. Permanent dentition achieves more effective posterior arch expansion with better torque control compares to mixed dentition. The clinical applicability of these findings requires cautious interpretation.
