Hello dentists,

As both a future dental student and a current patient of Invisalign,
I'm curious about something. My dentist let me spend a lot of time
looking at the 3D model of my teeth moving (the "clincheck") and I
noticed something strange. In the final three steps, it seems like my
bite gets corrected too far -- my protruding upper incisors get pulled
in just a bit farther than I expected, and my rotated lower canines get
rotated farther than it seems like they should. The software calls
these last three stages "overcorrection" and that seems to sum up what
I saw.

But what exactly is overcorrection and what is the purpose? While I
want my teeth right, I don't want my upper incisors pulled back in too
far so they look like reverse-bucked or something. Am I correct in
guessing the idea is that you move the teeth farther than you want
them, and then they start to go back a little bit and end up in the
correct place?
