Abstract
BACKGROUND: This study aims to compare the 'Nuvola®' system with 'Fantasmino®' 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® aligner and Fantasmino® 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® system has elastic properties of high performance, but its size does not encourage compliance throughout the day. Nuvola® 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.
