There is no buccal plate at #8 or 9 when the teeth are extracted as well as severe soft tissue defect at #8.  Osteotomy is initiated as palatal as possible (Fig.1).  When 3.5x13 mm implants are placed initially, the one at #8 is supracrestal (Fig.2 ^).  To reduce the chance of peri-implantitis, the implant is placed deeper (Fig.3 (~2 mm implant threads exposed buccally)) with placement of sticky bone around the implants and 4.5x5.5(4) mm abutments (Fig.3 *).
