Question – What else is a concern when it comes to tooth pairs in contact, apart from stability of the bite?

Answer – We have to consider static and functional occlusion (bite).  From a static standpoint, as long as teeth are in complete interdigitation with a class I canine relationship, even contacts upon bite closure with an adequate amount of overjet and overbite, that is our goal.  From a functional standpoint, when the jaw is in motion, it is preferred to have anterior guidance upon protrusion and canine guidance upon lateral excursion.  The posterior teeth should never touch during any jaw movements.
