At surgery, the mesiodistal space for #11 is found to be narrow, 5 mm.  To prevent buccal plate collapse, socket shield is planned.  Due to limited space, incision is attempted so that the lower end of the shield (Fig.1 S) can be trimmed slightly subcrestal.  It is also good for visibility for osteotomy (1.2 mm drill for 12 mm).  A 2.5x14(2) mm 1-piece implant is placed with <35 Ncm (Fig.2,3 (*: allograft)).  There is no bone loss 3.5 months postop (Fig.4).
