When the guide with 10.5 mm offset is seated at #11 after extraction, it looks buccal. Pointed drill creates an entry point in the mesial portion of the socket. PA, taken following 2.2x11.5 mm drill, shows acceptable mesiodistal trajectory (Fig.1). When a 3.5x11.5 mm implant is placed, it is difficult to withdraw the driver from the metal tube (Fig.1 *).
