After 4.1x12 mm SM implants are placed (Fig.4), they are placed .5-1 mm deeper (Fig.5); allograft (*) placed before and after insertion of 3.9x5.5(3) and 4.8x5.5(3) mm abutments.  The existing porcelain crowns (splinted) are hollowed and relined as provisional restorations.  The buccal papilla is slightly torn intraoperatively and sutured.  Three weeks postop, the provisional will be modified to make incisure between the 2 crowns so that the papilla can grow down.  In spite of modification, the patient complains of air leak between the crown.  Temporary abutments were used with new provisional on November 7, 2017.  The gingiva is healthier 8 months postop (Fig.8).  The sockets have disappeared.  The crowns are cemented without access holes 8.5 months postop (Fig.12, immediately post cementation (<: residual cement, which is to be removed)).
