The tag (Fig.2' *) is incised palatally (black line) and reflected buccally (Fig.3 *) to reveal the 3 sockets. Osteotomy is initiated in the center of the sockets, i.e., the convergent point of the 3 thin septi (Fig.3' black circle). Since the bone is dense and the septal top is pointed, the osteotomy has to be enlarged with Magic Drills sequentially (until 5.3 mm in diameter, 7 mm in depth).
