Can 3D printing make dentures fit better than traditional molds?
NCT ID NCT07795983
First seen Aug 31, 2026 · Last updated Sep 01, 2026 · Updated 1 time
Summary
This trial tests four ways of making upper denture bases to see which fits the mouth most accurately. Thirteen adults with no teeth in their upper jaw receive dentures made by conventional molding, fully digital 3D printing, and two hybrid methods. Researchers scan each denture and measure fit at 22 points across the palate and gums. The goal is to guide dentists toward the most reliable fabrication approach for better comfort and stability.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Comparison of four denture-making workflows: conventional, fully digital, hybrid early, and hybrid late
- What this could lead to
- If one method proves more accurate, dentists may adopt it to improve denture comfort and stability for patients.
- What could go wrong
- The trial is small with only 13 participants, so results may not apply to everyone. Fit accuracy does not guarantee patient satisfaction or long-term success.

Who is studied
Participants were randomly selected from the waiting list of patients scheduled for complete denture treatment at the Department of Prosthodontics, Faculty of Dentistry, Istanbul University. All fabrication workflows were performed for each participant; therefore, allocation indicated the fabrication workflow rather than participant assignment to different groups.
