Comparing digital mouth scans with traditional denture impressions
Official title: Accuracy of Intraorally Scanned Denture Impressions Compared to Conventional Border-Molded Impressions: An In Vivo Study
Run by Mohammed Bin Rashid University of Medicine and Health Sciences · NCT07377890 · Data updated 2026-11-12
We're testing whether digital mouth scans are as accurate and consistent as traditional border-molded impressions for adults who have lost all their teeth.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults (18+) who are fully edentulous, in good general health (ASA class 1 or 2), speak Arabic or English, and are seeking complete dentures at Dubai Dental Hospital.
✕Probably not a fit
Patients with remaining natural teeth, implant-supported complete dentures, severe gag reflex, or unstable mental health/substance use are unlikely to benefit or be eligible.

What this trial studies
This study compares intraoral digital scans with conventional border-molded impressions in fully edentulous adults. Participants will attend Dubai Dental Hospital for two visits, receive three repeated digital scans with an intraoral scanner, and then have a conventional impression taken using a custom tray and high-accuracy material after border molding. Researchers will quantify how closely each method captures the mouth's shape, including movable gum areas, and will measure the consistency of repeated digital scans. The goal is to see if digital workflows can match the traditional gold-standard technique for denture impressions.
Why it matters
Potential benefit: If successful, digital scanning could make denture fittings quicker, more comfortable, and reduce the need for repeat impressions or adjustments.
How similar studies have gone: Previous laboratory and some clinical studies have shown promising but mixed results for digital impressions in edentulous arches, so this in vivo comparison builds on emerging evidence.
