The initial osteotomy deviates mesial (Fig.3). To avoid perforation into the Incisive Canal, the trajectory is changed (Fig.4). After use of the final drill (3 mm), the coronal Incisive Canal is perforated. Following placement of a 3.5x13 mm implant and 4.5x5.5(4) mm abutment, Vanilla Graft is placed (Fig.5 *) to repair the perforation. Retrospectively, the coronal end of the Incisive Canal is revealed at incision (Fig.1 *).
