The abutment margin is completely subgingival 3 months postop (Fig.8 (white dashed line: gingival margin)). It appears that the implant is placed ~ 1 mm deeper than ideal (Fig.9). Diode laser is used for gingivectomy prior to impression.
It seems proper to place an implant at most 3 mm subgingival for flapless approach, since the gingiva may rebound in thickness postop.
