Following 1.5 mm drill for ~ 17 mm, a 3x16(2) mm 1-piece implant is placed >40 Ncm (Fig.3). After bone graft through limited access and abutment preparation, an immediate provisional is fabricated with clearance.  The provisional dislodges repeatedly, mainly due to palatal perforation of the provisional.  It gets lost while the patient travels to his home country.  Although there seems to be bone loss around the implant 2.5 months postop (Fig.4), the gingiva looks healthy.  A new provisional is fabricated without impression.  The bone loss remains 4 months postop when impression is taken (Fig.5).
