After mesial clearance is created (Fig.7 ^) and the crown/abutment is reseated, X-ray has to be taken for seating confirmation before pick up impression.  The abutment appears to remain completely seated when it is reseated with the repaired crown (Fig.8).  Then the crown is cemented.  After curing, the crown/abutment is removed for cement removal.  The screw is torqued at 20 Ncm.  The access hole is closed with plumber tape and composite.  If the screw is loose, please trim the mesial contact until it does not prevent passive seating (03/19/2021).
