Gingival Embrasure M

A 67-year-old woman has multiple restoration (difficult for guide preparation).  The tooth #6 fractures equigingival with a separated file (Fig.1 <).  Because of missing #7, the gingival embrasure between #6 and 8 is large (*).  To reduce it, the mesial crest will be trimmed by using 6 mm profile drill after placement of a 3.5x13 mm FC implant (low bone density) and a narrow temporary abutment is going to be used to squeeze the papilla coronally and mesially.  In a coronal section, osteotomy will be initiated in the middle of the palatal slope of the socket (Fig.2).  A 4 mm x15 degree ~3 mm cuff angled abutment may be used before impression.  Take preop photos to show the large gingival embrasure between #6 and 8. The other way to reduce the gingival embrasure is to place an implant mesially.  It appears that a 3.5 mm implant is too large for the mesial ridge (Fig.3), while a 2.5 mm one is proper (Fig.4,5).
