Crown Came off While Making Invisalign Molds - Will That Happen with Trays?
asked 2 years ago by sundevilgirl in Hawaii

Tags: combination, crown, recommendation
Yesterday I had my molds for Invisalign done. I have a crown on the upper left molar (tooth next to the wisdom...wisdom tooth was pulled years ago). When they pulled the hardened mold off, my crown came out with it. Went to my dentist (not the same dentist who did the crown) to glue the crown back. He said I will probably pop that tooth off every time I pop out the invisalign trays. I can't go everyday with that happening are there any other options? Is invisalign not an option for me? Please any advice, I just paid yesterday.

Invisalign and crown
You can cut the Invisalign tray where it fits over the crown. This will allow you to seat the Invisalign tray even if there is a new crown.

Invisalign does not create suction similar to impressions
You likely will experience nothing like when the crown came off, so I would not worry too much. Unless the dentist that feels it will continue to come off knows something about this specific tooth that is not being shared here, I would not anticipate a problem with the Invisalign treatment.

Shouldnt be a problem
For one thing when your Invisalign dentist does the treatment online he can actually exclude that tooth from your aligners, or even cut the aligners each time from that crown area and not loosen your crown. Also the aligners will probably not pull the crown off...just doesnt seem likely to me.

Crowns shouldn't come off with alignment trays
Impressions have much more "suction" or grab on the crown. I would anticipate that if it is a simple recementation you shouldn't have to worry about the crown coming off with the aligners. That said, if I were to do an examination of your mouth I may come to a different conclusion.
There may be good reasons to wait until Invisalign treatment is completed to finalize a new crown. For example if it is a front tooth, you may expose the margins of the crown if there is significant...

Crown needs to be secured before Invisalign
It is definitely an issue that your crown comes off every time you change an aligner. It is practically impossible to have it put back in the exact same place, and this may compromise the fit of the aligner.
In a more global dental view, the crown should not come off that easily. This show an underlying problem with either the crown, the cementation process, or the preparation of the tooth. It's a good idea to have this issue corrected before moving onto more "elective"...

Change the crown first
If the crown came out with an impression it obviously does not have enough retention. I would have your dentist remake the crown PRIOR to making the Invisalign trays. Invisalign will tell all dentists to make sure all dentistry in done prior to taking impressions.

Invisalign and crowns
It is hard to say whether your crown coming off during the invisalign impression is a one-time thing or if it will happen repeatedly, (since I have not examined your mouth).
I would speak with your invisalign doctor about your dilemna as there are a few options. It may be that the crown is not a good fit and needs to be redone. Permanently cemented crowns that fit right should not come off during the invisalign impression or when removing the invisalign trays. It may happen once, but if if...

Patient with loose crown undergoing Invisalign treatment
It concerns me that your dentist thinks the crown is going to continue coming off. I never expect my restorations to come off...and when they do, there is an underlying problem that needs to be fixed.
Are you seeing an orthodontist for Invisalign? It may be a good idea to find a skilled dentist and get a second opinion about that crown and your mouth/smile in general. Make sure the dentist is experienced and is up to date with technology.
