In fact, there is no gross buccal plate defect. No blood is collected for PRF. Osteotomy is difficult due to limited space with a parallel pin in place (Fig.9). After a 5x10 mm bone level implant is placed (~35 Ncm), allograft (mixed with autogenous bone and Osteogen) is packed in remaining socket (Fig.10 *). A 5.8x4(3) mm abutment is placed for an immediate provisional. There seems to be bone regeneration or reorganization around the implant 8 months postop (Fig.12 *). In fact the bone has grown into the threads of the implant.
