Dental scan showdown: which method saves time and reduces problems?
NCT ID NCT07446790
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two ways of taking digital dental impressions for people getting full-arch implant-supported teeth: intraoral scanning and photogrammetry. Researchers will measure how long each method takes and track any problems like screw loosening or chipping over 6 months. The goal is to find which approach works better for patients needing a full set of replacement teeth.
