Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Group I: Patients will be treated by Carriere Motion Appliance using passive lingual arch.
Group II: Patients will be treated by Carriere Motion Appliance using direct mini-screw.
For each patient, two CBCT will be obtained: one preoperatively and another after completion of distalization.
Comparing skeletal and dental measurements obtained from CBCT radiographs obtained prior to treatment (T0) and immediately after correction of class II and remval of the appliance (T1).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group I: Patients will be treated by Carriere Motion Appliance using passive lingual arch .
Conventional mandibular anchorage During the first month, 1/4-inch heavy elastics will be used. In the following months, 3/16-inch heavy elastics will be used. The patients will be instructed to wear the elastics 24 hours per day, except during mealtimes, and to change them daily
Carriere Motion Appliance
Patient will be randomly allocated into two groups:
Group I: conventional mandibular anchorage using passive lingual arch. Group II: anchorage by direct mini-screws. In the group I, Class II elastics will be attached from the maxillary canine to the mandibular first molar bilaterally with passive lingual arch in the lower arch as anchorage means.
In the group I, Class II elastics will be attached from the maxillary canine to mandiular miniscrews bilaterally.
For each patient, two CBCT radiographs will be obtained: one preoperatively and another after completion of distalization.
Group II: Patients will be treated by Carriere Motion Appliance using direct mini-screw.
