Sticky bone is placed to bury the implant at #14 (Fig.3 *).  After placement (incomplete, Fig.3 <) of a 4.5x7.5(4) mm pair abutment, setting acrylic is applied around the abutment, over the bone graft at #14 (to prevent loss) and pressed into the undercuts of the proximal surfaces of the neighboring teeth for retention (Fig.4).  The bone/implant gap reduces at #13 five months postop (Fig.7 (complete abutment seating)).  There is no implant thread exposure at #13 (immediate), while minor exposure mesial to #15 (delayed).
