Trajectory of site looks off. How do you test to ensure it is correct?

Assemble the spoon and drill and show the trajectory all the way to the bone. Often the sleeves seems lingual, but the sleeve is just the trajectory not the stopping point of the implants. In other words, the guide may look lingual, but it is in the position as designed.

Clinical judgement must be made if the guide clearly shows a wrong trajectory. Free-hand may be needed.
