Parallel PA (taken with sensor I) shows proximity of the healing abutment with the crestal bone (Fig.3). In spite of using a smaller cemented abutment, there is a gap between it and the implant, suggesting incomplete seating (Fig.4 < (use of sensor II)). If the screw becomes loose in function, a 6.0 mm profile drill has to be used.
