What the trial is, and whether it could suit you

The goal of this randomized clinical trial is to compare distalization of maxillary first and second molars achieved with a device supported with mini screw implants in the palate (Advanced Molar Distalization Appliance, AMDA®) with distalization of maxillary first and second molars achieved with clear aligners (Spark®) supported by Class II elastics. The main questions it aims to answer are: Is there any difference in achieving upper molar distalization with the Advanced Molar Distalization Appliance (AMDA®) supported by miniscrew implants and with clear aligners (Spark®) supported by Class II elastics at the end of active distalization phase? Is there any difference between the two groups in the anchorage loss at the end of total treatment? Additionally, the differences in the movements of premolars, canines and incisors will be analyzed in all three planes of space (sagittal, tran
