The present study will be a single-center, split-mouth, randomized controlled clinical trial. Patients undergoing orthodontic treatment with Invisalign aligners will be enrolled after signing the informed consent. Two different flowable composite resins will be evaluated for the performing of attachments using a split-mouth design: * group A: Filtek Supreme Flow (3M Unitek, Monrovia, Calif) * group B: Grandioso Heavy Flow (VOCO GmbH, Cuxhaven Germany) Digital impressions with iTero intraoral scanner will be performed. The resulting 3D images will be superimposed onto the reference STL model, representing the pre- planned ideal attachment configuration. Digital scans will be used to assess any changes in shape of the attachments. Each tooth will be separated from the others and superimpositions of the single tooth will be performed with ZEISS Inspect software.
