How does a scan work if the patient can't open their mouth fully, and/or we can't access all the molar regions?


We require that all interproximal spaces are able to be scanned in order to position jets there; additionally occlusal surfaces should be scanned as this area provides a biting surface for teeth to key into the mouthpiece during use.

The mouthpiece does have some volume to it, so if a scanner tip cannot reach, there may be some challenges with having the mouthpiece fit comfortably in that region. That being said, the distal surface of the terminal molar does not need to be scanned.
