INFILTRATED
All procedures were performed under local anesthesia and standardized as much as possible. Oral hygiene education was given to all patients. Patients were asked to rinse with chlorhexidine 0.2% chlorhexidine three times a day, starting from the day after surgery to the day of suture removal. Mouth washing with 0.2% chlorhexidine solution was also performed preoperatively. A local anesthetic containing a vasoconstrictor (articaine hydrochloride) was infiltrated into the retromolar region, ascending ramus, and masseter area to block cervical innervation. When the donor and recipient sites were on the same side, the incision was made like the wisdom tooth incision, extended as distally as necessary, and the full-thickness flap was removed. When the recipient and donor sites were in different quadrants, the incision was similar to the sagittal split incision. The masseter was reflected laterally using the Minnesota retractor. Four osteotomies were performed as described by Misch (Fig.
