Study Comparing Predicted and Real Tooth Crown Movements Using 3D Direct-Printed Aligners in Adults with Teeth Spacing

What this Trial Is About

Researchers are evaluating the efficiency of direct 3D printed aligners in moving the crowns of upper and lower front teeth in adults with spacing issues during orthodontic space closure. This study focuses on comparing the actual tooth movements achieved with these aligners to the predicted movements planned before treatment. The trial will include adult patients aged 18 to 45 years with specific dental conditions, such as Angle Class I or mild Class II malocclusions and spacing between anterior teeth. Participants will receive direct 3D printed aligners designed after intraoral scans and 3D digital simulations of their teeth. Patients will be instructed to wear the aligners and to activate their shape memory by placing them in warm water before use. Aligners will be changed every 10 days throughout the treatment period, which lasts between 9 to 12 months. At the end of treatment, a new 3D scan will be taken to compare the actual tooth movements with the planned movements using digital superimposition techniques. During the study, patients will undergo intraoral scans before and after treatment, and 3D digital models will be created to measure crown movement in millimeters. These measurements will be analyzed statistically to determine the aligners effectiveness in achieving planned tooth movements. The study includes careful monitoring of dental health and malocclusion status, with no blinding or control group. The total duration of treatment and observation will be 9 to 12 months.
