When 2.5x10 mm 1-piece implant is placed in the middle of the edentulous area mesiodistally, the clearance from the Mental Nerve is 1 mm (Fig.2 (B: buccal).

When 2.0x10 mm 1-piece implants are placed evenly (mesio(M)distal(D)ly), the clearance from the Mental Nerve is more, ~2 mm (Fig.4,5).  It would be safer to place the implants slightly above the crestal bone.
