Why were my impressions rejected?

We ask you to redo your impressions when they don’t capture the position and shape of your teeth in enough detail. For example, your impressions would be rejected if they were too shallow to show the line where your teeth meet your gums, or if your teeth scraped against the side of the tray and ruined the impression when you pulled them out of the putty.

The impressions are intended to serve as the basis for a digital model your orthodontist will use to create your custom treatment plan. The fidelity of that model — the level of anatomical detail it provides — is a key factor in your care: If it isn’t a precise rendering of your teeth and gumline, your orthodontist won’t be able to design and engineer a truly individualized plan. So the quality of the initial impressions is crucial.
