Digital showdown: which scan is best for toothless patients?
NCT ID NCT07211022
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested how accurate two digital scanning techniques are for making dental impressions in people who have lost all teeth and received implant-supported bridges (All-on-4 or All-on-6). Eleven adults were scanned with both a special camera (photogrammetry) and a wand-like intraoral scanner. The goal was to see which method better captures implant positions, which can help dentists choose the best approach for fitting permanent teeth.
