Fig.3 (Intraop PA): Protocol for placing 3 mm one piece implant is to use 1.5 mm pilot drill (Fig.3) to the depth of osteotomy and 2.0 mm pilot drill half distance of the osteotomy. There is moderate to severe bone loss around the neighboring teeth.  The patient is a heavy gagger.  #1 sensor is used to take intraop PA.  The tip of the pilot drill is not revealed.

Both the buccal and lingual plates are severely lost.  In fact the lingual wall is lower than the buccal.  The proximal walls are also low.  Bone graft is anticipated.
