The aim of this study is to evaluate the center of resistance of the maxillary central incisor during intrusion. The study employed the following steps: pre-processing, which involved creating a geometric model, mesh generation, and boundary conditions; and post-processing, which involved analyzing tooth movement and determining the center of resistance. The results showed that the center of resistance for the maxillary central incisors was measured to be 6.67 mm and exhibited maximum resistance to movement from the applied force. This study provides a sound mechanical method of analysis that is sufficient to provide insight into the interactions between orthodontic forces and dental tissues, and it is reliable. Clinically, this study can be used to precisely locate the center of resistance in single-rooted teeth during orthodontic treatment.
