New treatment option for Distalization
Official title Comparison of Distalization of Maxillary First and Second Molars Between a Miniscrew Implant Supported Device and Clear Aligners.
ClinicalTrials.gov ID: NCT07040176
What this study is testing
- What it's testing
- 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?
