Summary

Patients at the Orthodontic Department of the University of Damascus Dental School will be examined, and subjects who meet the inclusion criteria will be included. Then, initial diagnostic records (diagnostic gypsum models, internal and external oral photographs, and radiographic images) will be studied to ensure that the selection criteria are accurately matched.

This study aims to compare two groups of patients with mild to moderate skeletal Class II malocclusion (ANB angle between 5° and 7°), a normal to slightly increased vertical growth pattern (Björk's sum \> 390° and \< 406°), and an overjet of 5-10 mm. Experimental group: the patients in this group will be treated in the canine retraction phase with a sliding on a round-section archwire of 0.020 inch Control group: the patients in this group. Maxillary canine distalization was carried out using sliding mechanics on a 0.019 × 0.025-inch stainless steel archwire.

Conditions

  • CLASS II DIVISION 1 MALOCCLUSION
