When a 5x12 mm bone-level implant is placed (Fig.4), there is a gap mesiobuccally, which is later filled with bone graft (Fig.5 *). A large abutment (7.8x4(3) mm) is placed immediately (Fig.5 A) for an immediate provisional (P) to close the sockets.
As expected, the lingual margin of the abutment is suprgingival 2 months postop. The immediate provisional is fractured (Fig.6).
The bony defect appears to be repaired 1 year 9 months post cementation (Fig.9).
