I'm doing invisalign, I'm on the second week of tray 3 and Doc had me come in for attachments and IPR and then continue wearing tray 3 for one more week before switching to tray 4. He shaved off .3mm between my top two front teeth, incisor, canine, and first premolar (on each side). The tx was to fix my overjet, crowding and my bite. I apologize, I didn't take any "before" pictures so I just included some close up's of my smile before the IPR, and then of course the aftermath.
