Custom-made versus ready-made Carriere Motion appliance for correcting Class II bite

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional comparison tests a custom-made Carriere Motion Appliance assembled from brackets, buccal tubes, a stiff wire, and NiTi coil springs against a commercially ready-made Carriere Motion Appliance. Participants are adolescents aged 12–15 with full permanent dentition and a bilateral end-on Class II molar relationship treated at the Faculty of Dentistry, Mansoura University. Patients with systemic conditions, harmful oral habits, transverse discrepancies, or prior orthodontic treatment are excluded. The study will compare the two appliance types for their effects on Class II correction, including distalization outcomes and appliance performance.
