Application of a 3D fusion model to evaluate the efficacy of clear aligners: A clinical study

Clear aligners have become a popular orthodontic treatment alternative due to their aesthetic and hygienic advantages. A prospective clinical research was conducted on 30 patients undergoing aligner therapy. Mesiodistal and vertical movements showed minimal discrepancy (mean <1 mm), with no significant differences. However, rotation, angulation and torque demonstrated significant deviations (p < 0.05), with over 40% of teeth showing severe discrepancies in these categories. A 3D fusion model enhances clinical accuracy by identifying movement-specific discrepancies, aiding in treatment planning and refinements.
