A 65-year-old woman cracks the tooth #14 prior to #4 implant (Fig.1). The height of the septum is ~ 10 mm; initial osteotomy depth will be 8.5 mm; 1-2 mm from the sinus floor. While increasing the drill size, check whether there is perforation on the side of the osteotomy apically. Since the patient is small, start low dose of X-ray.
