Root Resorption and Alveolar Bone in the Maxillary Canine Retraction Using Injectable Platelet-rich Fibrin: A Split-Mouth Trial

After the leveling and alignment phase, the canines were retracted with 150gm forces. The i-PRF was prepared from the blood of each patient then injected immediately before canine retraction on the buccal and palatal aspects of the extraction sites. All patients in this study were submitted for Cone beam computed tomography (CBCT) scanning before and after canine retraction. Cone beam computed tomography (CBCT) was used before and four months after retraction, with imaging conducted using the Orthophos SL 3D X-ray machine (Dentsply Sirona, Charlotte, CA, USA) while adhering to As Low As Reasonably Achievable (ALARA) guidelines to minimize radiation exposure
