Digital showdown: which scan is best for toothless patients?

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.
