Invisalign ABSOLUTELY corrects over - bite faster and with far, far, less discomfort then the use of conventional braces.There are several irrefutable reasons for this: the first is that being a "pushing " appliance (it works as you bite into it) the dual benefits is that over- bite is easily corrected by depressing (intruding) your front teeth,while simultaneously elevating (extruding) your back teeth. However, mantaining (keeping) this over- bite reduction HAS ABSOLUTELY NOTHING TO DO WITH WHETHER INVISALIGN,OR REGULAR BRACES ARE USED! The sole determinant of post treatment stability appears to be essentially genetic, as most studies have resulted in one irrefutable conclusion:40% of all orthodontic cases treated (whether by Invisalign or conventional braces) will have a tendency to revert to their original tooth positions.granted this return is usually only a partial one,to minimize this tendency in my practice, 100% of all of my invisalign cases are given retainers. their use and duration is the topic of another question
