After immediate implant at the site of #19, pain is getting worse at #15 (Fig.1 CT sagittal section through the buccal roots).  The patient requests extraction, although the etiology of the pain remains unknown.  The tooth #14 has been missing (with loss of the sinus floor) for 13 years.  The tooth #15 has tilted mesially.  If an immediate implant is placed along the long axis of the tooth, it is 14 mm long (e.g., 6x14 mm).  This leaves short dimension for the future crown at the site of #14.
