This article aims to study, measure and verify through Reverse Engineering techniques and 3D analysis, the results obtained by an orthodontic treatment for the alignment of the teeth, using clear aligners (CA). A case study of a patient who followed orthodontic treatment using a set of 19 CA was analyzed: dental impressions by intraoral scanner were made before and after treatment; the study also analyzed the project planned by Invisalign ClinCheck® software, comparing it to the results clinically obtained, using specific software and hardware. The analysis of the obtained results shows that the measurements carried out are affected by a residual error respect to the final situation designed for the patient, caused by several factors here investigated; moreover, it is very determinant to do a correct diagnosis, to formulate an adequate treatment plan and to correct wear the chosen orthodontic appliances.
