Initial Displacement and Stress Distribution of Upper Central Incisor Extrusion with Clear Aligners and Various Shapes of Composite Attachments Using the Finite Element Method
Folding Canes A clear aligner is an esthetic and more comfortable option for patients who need orthodontic treatment.However, some types of tooth movement, such as extrusion, are difficult with this tool.Therefore, composite attachments have been suggested to improve tooth movement.This study aims to evaluate the initial displacement and stress dis
