The aim of this randomized controlled clinical trial is to evaluate the dentoalveolar and skeletal treatment effects of the AMDA when used for distalization of the maxillary first molars in patients with Class II malocclusion in the permanent dentition.
The primary aim is to evaluate two different treatment groups from initiation of treatment up until completion of maxillary molar distalization of: * Group I: patients treated with amda® * Group II: patients treated with buccal mini-implants More specifically to evaluate the efficiency of the AMDA using lateral cephalograms and digital 3D model casts of the patients under investigation at the following time points: * point T0: baseline data - before initiation of the treatment * point T1: immediately after distalization (8-12 months)
