Avoid IPR by Widening Arch?
Can IPR be avoided by widening or reshaping the arch of top and bottom teeth during refinement? I already had over 4 mm of IPR total done during the initial express treatment to address protrusion and crowding that did not work as well as expected and would like to avoided any further IPR. Is this an valid option I could let my ortho know? My arch is of a V shape now. Can it be changed to a U shape - in other words are there any limitations of arch widening with Invisalign?
Yes arch widening reduces IPR requirments.but
Upper jaw widening can be accomplished with dentofacial orthopedics.
