Q: I have a class II case that will slide his mandible forward on closing to spot. That’s not OK, right?!
A: If it is a severe Class II, they probably should not be seen until it is corrected orthodontically or surgically if necessary. If it is not too extreme, remember that we explained in class that they will have to place their tongue tip a bit further back and maybe even slightly behind the spot; otherwise, when they close, they will be biting the tongue! Hopefully you can find a place where they do not have to slide forward since that is not something that can be interwoven into the treatment program and it cannot lead to habituation of new resting postures of the tongue, mandible and lips. Good luck with that severe class II.
