Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the present prospective observational study is to evaluate the accuracy of dental movements in the three planes of space, assessing the correspondence between the virtual planned movements and the clinical outcomes achieved using thermoformed or 3D printed orthodontic aligners. The study will include patients who are candidates for aligner orthodontics treatment. After having acquired the standard initial diagnostic data (clinical examination, intra- and extra-oral photographs, intra- and extra-oral scans, orthopantomography and lateral-lateral teleradiography of the skull), the digital impressions of the arches will be used to plan the dental movements necessary for correction of malocclusion.

The aligners will then be designed using orthodontic CAD software and realized using a thermoformed and direct 3D printing process.

All patients will be treated following current recommendations relating to the orthodontic treatments in question. After delivery of the aligners, during each check-up, intra-oral and extra-oral scans will be acquired to evaluate the actual position of the teeth and, using special software will be compare the virtually designed position with tooth with the clinical outcomes. Any discrepancies will be recorded and statistically analyzed.There are no additional invasive procedures. Intra- and extra-oral scans will be acquired regularly to monitor the extent of tooth movement over time.
