When a narrower abutment with longer cuff is placed at #15, there is no gap between the implant and abutment.  In contrast there is one at #13 (Fig.6 <) when a 4x4(4) mm abutment is seated following removal of a healing abutment.  After use of a 4.6 mm profile drill, the gap disappears (Fig.7).  Impression is taken.
