I'm on tray 3 of 44 for my invisalign treatment. I just got attachments put on today
A passive aligner would mean that it is not actively moving any teeth. This is a great feature as you don't have to wear your previous aligner an extra 2 weeks (or more) until the movement is active again. So, basically, you will be changing to a new set of upper and lower aligners even if no movement is happening in one of them. Best,Dr. Pam
A passive aligner in Invisalign does not cause teeth to move. Your dentist may just want you to get use to the attachments before more pressure is added. Taking the aligner on and off with the attachments on has a learning curve to it. As it gets easier the added pressure won't bother you as much. Hope that helps!
