Alveolar Bone Dehiscence and Fenestration Following Accelerated Maxillary Canine Retraction

PRP (0.7 ml = 70 unit) will be injected submucosal disto-buccal and disto-palatal to the maxillary canine like the local anesthesia injection in group I experimental sides

Experimental sides will receive PRP injection after performing decortication. After administration of local anesthesia, two-line flap will be performed from the mesial surface of the maxillary second premolar to the distal surface of the maxillary canine Mucoperiosteal flap will be reflected in the buccal side. Two millimeters of marginal crestal bone will be held intact and using a high-speed drill and a round carbide bur (1mm diameter) under copious saline irrigation, the cortical wall will be penetrated to reach marrow spaces. Multiple perforations (10 holes for standardization) in the cortical bone will be created. The surgical site will then rinsed, and the flap will be repositioned and sutured.
