Efficacy of Biological Technique in Upper Canine Retraction and Levels of Discomfort
Malocclusion, Angle Class II, Division 1
About this trial
This is an interventional treatment trial for Malocclusion, Angle Class II, Division 1 focused on measuring i-PRF (injectable platelet rich fibrin), canine retraction, pain and discomfort

i-PRF assisted upper canine retraction
conventional upper canine retraction
I-PRF assisted upper canine retraction will be performed in one side of patients with Class II Division 1 malocclusion patients requiring therapeutic extraction of the maxillary first premolars
Conventional upper canine retraction will be performed in the other side of patients with Class II Division 1 malocclusion patients requiring therapeutic extraction of the maxillary first premolars
