In spite of a shorter implant (3.8x13 mm) placed deeper, approximately 7 mm implant threads are not covered buccally by the native bone (Fig.6 red dashed line).  If the implant were placed deeper, the crown/implant ratio would become more unfavorable (abutment screw loosening, Fig.7).  Since a mill abutment (4.5(2) mm) is inserted before Vanilla Graft, the deepest portion of the socket is unfilled (Fig.7 *).  With meticulous use of a long explorer and additional allograft, the space is closed (Fig.8 *).
