i got old style impression. will that be inaccurate?
Byon 17 Jun 2012
i thought the provider would use the computer to directly get the 3D image of my teeth, and then make sets of my invisilgn. however, they use the old style impression to get the modle of my teeth first and mail to somewhere eles,then based on my teeth modle they get 3d and make invisilgn. i am super worried if this way will lead the invisilgn sets to be unmatched to my teeth? should i stop and change to another provider with better technology? i paid already : (
