When the tooth #19 is extracted, the mesial socket is larger than the distal one.  The initial osteotomy is set up mesial to the septum (Fig.1 <), 8 mm from the septal crest, 6 mm from the bottom of the mesial socket.  There will be 6 mm new bone to support an implant.  When a 5x10 mm implant is placed (Fig.2 with 50 Ncm), the coronal threads are exposed circumferentially.
