Should attachments be left on when impressions are made for Invisalign mid-course correction?

Question

I am on Invisalign aligner 19 out of 29 for my uppers and my teeth stopped tracking so my ortho said I needed a mid course correction. When his assistant took a new set of impressions for my teeth the attachments were left on and not removed prior to the impressions. Was this proper procedure?

Odds are strong that the dental office knows what they are doing. If you have doubts, you should talk to them.

Normally , dentists would take the attachments off as teeth have not moved the way they were supposed to. So the new positions could be different. But still they are the best people to determine your exact tooth movement and so devise your treatment plan. So trust them or ask them if in doubt, not the assistant.

Yes a lot of times the attachments are left on the teeth
when new impressions are taken, unless your doctor wants to change their position.
It is also possible for new attachments to be added later.

Lawrence Singer, DMD (in memoriam) · Answer

Yes the attachments should be left on.  Presumably the movements you are trying to accomplish are still the same.  Removing the attachments at the time of impression might entail putting them right back on.  Invisalign is aware of what is tooth and what is attachment.  Have faith, stay the course and good luck!!!
