3D-printed dentures using digital vs hybrid workflows in full-arch dentures
Official title: Clinical Success, Oral Health-Related Quality of Life, and Relationship Between Maximum Masticatory Force and Denture Wear in Complete Dentures Fabricated by Additive Manufacturing Under Digital and Hybrid Workflows: A Prospective Randomized Crossover Clinical Trial
Run by Universidad de Especialidades Espiritu Santo · NCT07626827 · Data updated 2026-11-12
This study tests two 3D-printed denture fabrication methods (digital and hybrid) in adults who are completely without teeth to see which setup provides better fit, comfort, and quality of life.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are completely edentulous adults aged 50–90 who need bimaxillary complete dentures and can provide informed consent.
✕Probably not a fit
Patients with unimaxillary edentulism, certain tissue conditions, no prior denture experience, or cognitive issues may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
In this randomized crossover trial, adults 50–80 with complete edentulism receive two sets of dentures: one made with a digital workflow (direct intraoral scan, CAD design, 3D printing) and one with a hybrid workflow (digitized functional impressions, CAD design, 3D printing). Each participant uses each denture set for about 2 months in a randomized sequence, with no washout period, for a total follow-up of roughly 4 months per participant; a longer follow-up of 12 months after the second insertion assesses longer-term outcomes. The study aims to compare clinical performance and patient-reported oral health-related quality of life between the two fabrication methods. The trial is designed as prospective, controlled, randomized, double-blind for participants and outcome assessors, and conducted at UEES in Samborondón, Ecuador.
Why it matters
Potential benefit: If successful, the digital workflow could offer more precise, reproducible dentures that improve patient comfort and oral health-related quality of life.
How similar studies have gone: Existing work suggests potential benefits of digital and hybrid CAD-CAM denture fabrication, but robust comparative evidence remains limited.
