Use heavy body and light body material to get the best results.
Teeth cleaning before impression taking is recommended.
Always dry the teeth with air to remove saliva bubbles in the impression.
The impression material should be of the right consistency otherwise inaccurate molds can result in improper fitment for the aligner.
Double imprints should be avoided at all costs.
The gumline impression should be accurate. It should be free of voids, bubbles, thin walls, shifts, tears, and double imprints.
Mold made from impressions can be scanned using a digital desktop scanner and used for import into dental aligner software.
