Following block anesthesia, the initial osteotomy depth extends to 8 mm (Fig.3,4).  Without 4.9 mm clearance (red dashed line: apparently the superior border of the Inferior Alveolar Canal), the osteotomy is further extended to 10 mm.  The osteotomy walls are apparently intact without severe hemorrhage after each drill.
