A comparative study of two different clear aligner systems

Background: This study aims to compare the 'Nuvola (R)' system with 'Fantasmino (R)' system, examine their material properties, and define the indications for use of the aligners. Methods: Two groups of patients were selected and were respectively treated with Nuvola (R) aligner and Fantasmino (R) system. Results: The goal of treatment has been achieved with the two systems. Conclusions: The two types of aligners have shown differences during the treatment. Fantasmino (R) system has elastic properties of high performance, but its size does not encourage compliance throughout the day. Nuvola (R) system determines good tooth movement and its size facilitates the patient's collaboration. In both aligner systems, difficulties were found in the correction of torque information and rotations.
