Five weeks post 2nd implant placement, the osteotomy opening has healed. After Cetacaine topical application, use an explorer to penetrate the gingiva and remove the underlying healing screw. A 4.5x7(3) mm cemented abutment is placed. Clearance from the lower incisor is provided by grinding the palatal surface of the abutment at the cervix (Fig.15, taken 1 week after provisionalization.). In addition, the palatal cervical extension is intentionally trimmed short of the early provisional (crown shell).
