Torque correction of maxillary central incisors and rotational correction of most of the teeth showed significant differences.

The digital impressions of 21 subjects treated with Invisalign Lite were taken and analysed. Subjects were white with a mean age of 20 years. Patients were analysed at T0 (before starting therapy) and T1 (after 28 weeks of treatment), with a two-week change interval. The changes that occurred between T0 and T1 were compared to the predicted changes between T0 and Ts (setup/ClinCheck). The teeth that exhibited the least accurate expression of torque were the central incisors. Tip was not accurate on maxillary central incisors and canines, mandibular central incisors, lateral incisors, first premolars, second premolars and first molars. Rotations were under-expressed on maxillary lateral incisors, canines and second premolars and on mandibular central incisors, canines, premolars and first molars. Overall, angular changes showed a tendency to underperformance. Transverse linear changes were accurate with a significant overperformance on all first molars.
