After implant placement (Fig.2), sticky bone is placed at #18 (Fig.3 red dashed line (yellow: superior border of the Inferior Alveolar Canal)). PRF membrane and an immediate provisional FPD (#18-20) further keep the bone graft in place for healing. The crest may interfere with abutment seating. The abutment at #19 is incompletely seated and will be later changed to the one with 3 mm cuff.
