The crown/abutment is loose 2.5 years post cementation due to incomplete abutment seating (Fig.8 < (no clearance between the abutment (A) and the mesial crest (C))).   In fact the abutment has been incompletely seated since day one (Fig.5) and remains so 4 months postop (Fig.7).  A 6x3 mm healing abutment is placed.  When the patient returns, try in the smallest abutment with 2 mm cuff in the Planning Kit and place probably a 4x4(3) mm pair abutment from 5x4(2) mm existing one.  Torque and take PA with sensor 1 to confirm seating before impression. Or use 5.5 mm profile drill before reseating the crown/abutment.
