At the sites of #11 and 12, the knife-edged ridge is trimmed prior to initiation of osteotomy (Fig.12,13).  With the flattened ridge, it is easy to start osteotomy and control the mesiodistal position.  When the position and the trajectory are not correct, they can be changed (Fig.14-16) with 2.5x14(4), 2.5x12(2) and 3x10(2) mm implants placed at #11,12, and 13, respectively.  With relatively correct position of each implant, it would be easy to fabricate a splinted 6-unit provisional.
