The edentulous ridge at the site of #2 is wide. Magic split is used to gain access, test bone density and start osteotomy for 9 mm (gingival level). A 1.6 mm drill is used to extend the osteotomy for depth of 13 mm. The osteotomy position and trajectory is confirmed with a parallel pin (Fig.1), which is ideal.
