Patients at the Orthodontic Department of 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, as well as radiographic images) will be studied to ensure that the selection criteria are accurately matched. The aim of this study is to compare flapless bone cutting by mechanical drills to evaluate the acceleration of the retraction of upper canines versus traditional bone cutting by piezo-surgery in comparison with a control group without bone cutting after extraction of upper first premolars in class II type I patients.
