Purpose: To explore the efficiency of posterior teeth extrusion with clear aligners by 3-dimensional model superimposition, which provides a reference for the design of clinical programs.
Methods: We selected 24 patients with clear aligners whose posterior teeth were designed to extend more than 0.5 mm, and a total of 126 teeth were included.
Article Synopsis
- * Twenty-five patients, aged 15 to 29, were analyzed to assess factors like midpalatal suture density and maturation, finding that older age negatively impacted bone and alveolar expansion.
- * Results suggest that age, midpalatal suture maturation, and suture density should be considered for optimizing MARPE treatment outcomes.
