NCT06011382

Brief Summary

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.

Study Arms (2)

patients treated with amda®

ACTIVE COMPARATOR

two different treatment groups will be evaluated, from initiation of treatment until completion of maxillary molar distalization.

Device: Advanced Molar Distalization Appliance (amda®)

patients treated with buccal mini-implants

ACTIVE COMPARATOR

from initiation of treatment until completion of maxillary molar distalization.

Device: Buccal mini-implants

Interventions

AMDA is a prefabricated device anchored to the palate by miniscrews and it is a noncompliance appliance for maxillary molar distalization
