IMPACTION
(A) The first corticotomy procedure involved drilling a series of circular holes (1 mm in diameter, 1-2 mm deep and spaced about 1.5 mm apart) in the cortical bone. (B) The second corticotomy procedure performed using piezosurgery. Two to three vertical gingival incisions with a height of 8 mm were made at the buccal side of the impaction area using a surgical scalpel. Then, the cortical cuts were created using BS1 tip with a cutting depth of 2 to 3 mm and 2-mm spaces between the cuts. Each cut was 1-mm width.Two months after the first corticotomy intervention, the second flapless corticotomy procedure was performed using piezosurgery (Mectron PIEZOSURGERY
