Comments
  • Dr explained to put that everything is exactly where he wants it to be except one tooth the upper right 6 which is a crown. Explained that the way the arches work the upper should be slightly broader than the lower keeping the cheeks away while we chew, etc. The pt’s Upper right 6 crown does not stick out farther than the lower (crossbite , which is where pt started.) pt understood and was ok with this. Dr explained that if he ever got his crown replaced they could make it that way.
