Evaluation of Accuracy of 3D Printed Aligners in Comparison to Thermoformed Aligners in Orthodontic Patients

The goal of this randomized clinical trial is to compare the accuracy of tooth movement achieved by 3D printed aligners versus thermoformed aligners in patients with lower anterior crowding. The study aims to evaluate whether directly printed aligners provide more accurate and predictable orthodontic tooth movement compared to conventional thermoformed aligners.
