A 60-year-old man has worn an upper partial denture for a while.  We are in a process replacing it with implants.  Next step is for #3 and then #2.  It appears that bone density in the edentulous region (Fig.1 (CT sagittal section) *) is low; the height is also limited (between 3.78 to 6.02 mm).  A cylindrical or tapered soft tissue level implant (4.5 or 5x11 mm) is planned.  Sinus lift is anticipated (red circles).  What instruments should we prepare in dealing with low bone density and sinus lift?  This patient does not like osteotomes.
