A 4x14 mm implant is placed with insertion torque of 35 Ncm (Fig.6 I).  It is deviated distally.  The immediate provisional is difficult to be fabricated because of the deviation of the implant.  The provisional is dislodged by the evening.  The problem is due to using a short abutment (A: 3 mm).

The deviation of the implant should have been fixed by overcorrecting the position (not just angle) of the initial osteotomy (Fig.7 red arrow).
