Fig.4: A 2 mm pilot drill in place (8 mm deep).  The upper center of the pilot drill is 5.41 mm from the distal root of the tooth #30, which is ideal.  But the trajectory of the pilot drill needs be adjusted, while the depth will be increased to 10 mm.

Changes which need to done (mentioned above) are shown in Fig.5 (4.5x10 mm drill with stopper (^).
