TADs Anchored vs Conventional Anchored Carriere Motion Appliance

Not Applicable

Completed

• Conditions: Class II Malocclusion
• Interventions: Device: Carriere Motion Appliance

• Registration Number: NCT05631353
• Lead Sponsor: Al-Azhar University

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.

Detailed Description

Twenty class II malocclusion patients with age (11-16) years will be randomly allocated in the two groups:

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).

Arm && Interventions

Group	Intervention	Description
Group II: Patients will be treated by Carriere Motion Appliance using direct mini-screw.	Carriere Motion Appliance	TADs 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
Group I: Patients will be treated by Carriere Motion Appliance using passive lingual arch .	Carriere Motion Appliance	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
