A relatively smaller implant should be able to achieve primary stability in the septum (Fig.4, as compared to Fig.2). The deeper portion of the sockets will be filled with collagen plug, while bone graft is used to cover exposed implant threads. If the 17 mm long implant has questionable stability, longer one will be placed (Fig.5). A 5x5 mm abutment will be most likely used for the shorter implant, whereas a shorter abutment for the longer implant.
