Hi Dr. Brooks and all,
Try the canal for the anterior superior alveolar nerve/artery (branching off the infraorbital branch of V2). See if you can trace it back to the infraorbital canal. I've seen a couple of cases like this where I've had to steer the dentist clear of placing an implant through that canal :S
May I suggest an excellent anatomy book that came out last year: Netter's Head and Neck anatomy for dentistry. I truly indispensible reference when looking at CBCT scans, or any imaging for that matter.
