CMC for 2 mm Sinus Floor

A 42-year-old man is interested in restoring the missing teeth #3 and 9 with implants after that at #14.  It appears that the bone density at the ridge of #3 is low (Fig.1 *).  Sinus lift may be accomplished directly with Magic Sinus Lifter.  If not, use short Magic Drill with 1 and then 2 mm stoppers (Fig.2,3).  Since the sinus floor is thicker mesially (Fig.2), establish osteotomy as mesial as possible.  Lean Lindamann bur or Magic Drill mesially if needed.  Place PRF and Vanilla Graft before insertion of a 4x9 mm dummy implant.
