After extraction of the tooth #24 with vertical root fracture (loss of buccolingual plates), osteotomy is initiated with 1.2 mm drill free hand; the trajectory seems satisfactory (Fig.1). With sequential osteotomy, a 2.5x14(2) mm 1-piece implant has difficulty being placed deep (Fig.2), apparently associated with dense bone. *: bone graft placed mesiodistal to the implant.
