Prevention of Mandibular Third Molar Extraction- Associated Periodontal Defects Using Platelet-Rich Fibrin

After loco-regional anesthesia was administered, a full-thickness mucoperiosteal flap was raised. The flap incision was extended from the vestibular side of the retromolar trigon to the second molar, corresponding to its distolingual cusp. The incision continued intrasulcular at the second molar and proceeded with a release incision distally to the papilla between the first and second molars, on a 45° angle. An osteotomy using a Lindemann burr under constant irrigation, followed by an odontotomy using a diamond burr was performed, if necessary
