In spite of underprep (4.0x8.5 mm last drill), a 5x8.5 mm implant is placed at #2 with insertion torque ~ 15 Ncm (Fig.1).  In addition to the large defect post implant removal with 4.5 month bone graft, he is a heavy gagger with limited mouth opening.  Drill cylinders may not engage the metal sleeve precisely.  A 5.5x4 mm healing abutment is placed with low emergency profile.  PA taken 1 month postop shows slightly subcrestal placement (Fig.2).  When a cemented abutment is placed 4 months postop, there is tenderness.  In fact the implant is mobile.  A 8x5 mm healing abutment is placed.  Nine months postop, the implant remains slightly mobile (Fig.3); a healing screw is placed.  Low Torque Last Next Xin Wei, DDS, PhD, MS 1st edition 11/27/2018, last revision 12/16/2019
