TADs Anchored vs Conventional Anchored Carriere Motion Appliance

NCT05631353 | Completed

Brief Summary

Carriere Motion appliance (CMA) was designed to correct a Class II molar relationship into a Class I relationship by distalizing the whole posterior maxillary segment by means of class II elastics and mandibular anchorage. To revoke the adverse effects of CMA with class II elastics, we can use the CMA to distalize the maxillary posterior segment with TADs anchorage using miniscrews. The aim of this study is to evaluate TADs anchored CMA vs. conventionally anchored CMA for distalization of the maxillary buccal segment.

Study Arms (2)

Group I: Patients will be treated by Carriere Motion Appliance using passive lingual arch .

ACTIVE COMPARATOR

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

Device: Carriere Motion Appliance

Group II: Patients will be treated by Carriere Motion Appliance using direct mini-screw.

Interventions

Carriere Motion Appliance DEVICE

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.

Also known as: Passive lingual arch., Mini-screw.

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.
