Using a virtual diagnostic set-up, the OrthoCAD iQ system places brackets, not to make the teeth straight, but to maintain the desired end result. How does it work with the end in mind?

Imagine a bracket on the LL1 and the LL6.

iQ conceptually draws a straight line from the slot of LL1 back to the LL6.

iQ places the slots of the prescribed brackets following the straight drawn line.

Voila! You see the resulting post treatment result before treatment even begins.
