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).
