dc.description.abstract OBJECTIVES: To investigate the predictability of transverse changes with Invisalign®. MATERIALS AND METHODS: Sixty-four adult Caucasians patients were selected to be part of this retrospective study. Pre and post-treatment digital models created from an iTero® scan were obtained from a single orthodontist practitioner. Linear values of upper and lower arch widths were measured for canines, premolars and first molars. RESULTS: For every maxillary measurement, there was a statistically significant difference between Clincheck® and final outcome. (P < .05) For every lower arch measurement at the gingival margin, there was a statistically significant difference between the Clincheck® planned expansion and the final outcome. (P < .05) CONCLUSIONS: The mean accuracy of expansion planned with Invisalign® for the maxilla was 72.8%, (82.9% for the cusp tips and 62.7% for the gingival margins.) Lower arch presented an overall accuracy of 87.7%, (98.9 % for the cusp tips and 76.4% for the gingival margins.) en_US
