The abutment is removed again; with a small piece of gauze in the implant well, the buccal and palatal plate defect is repaired with PRF and allograft (Fig.6 *) internally (through the socket, flapless).  The angled abutment is re-inserted, hand tightened, prepared and adapted to the crown shell (Fig.9).  Twenty days postop, the implant is found to be loose and removed.  It appears that deep bite, short implant (11 mm), osteoporosis and change in implant position in the previous placement are unfavorable factors.  What can be changed now is an increase in the depth of osteotomy (Fig.10: 20 mm) and implant diameter (Fig.11-13:4 mm).
