2nd Option for Narrow Ridge

is to place an implant deep with sinus lift.  Although the final implant is Tatum (4.5x14 mm), use IS 4 or 4.5x10 mm dummy implant to finish sinus lift.  Also prepare BW for implant placement level.  Trim the mesial bone if necessary.  Or start osteotomy depth first, probably until 8.5 mm, increase the diameter and check the sinus floor each step.
