Digital showdown: which impression technique fits the resorbed jaw best?
NCT ID NCT07764640
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This study compares three common dental impression techniques for people with severely resorbed lower jaws who need complete dentures. Using 3D scanning and deviation analysis, researchers will measure which technique produces the most accurate final impression. The goal is to identify a method that could lead to better-fitting dentures and improved comfort for patients with significant bone loss.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Three dental impression techniques: conventional (alginate and zinc oxide eugenol), wax, and compound, each followed by alginate.
- What this could lead to
- If one technique proves more accurate, it could improve the fit and comfort of dentures for people with severely resorbed lower jaws.
- What could go wrong
- This is a small study with only 8 participants, so results may not apply to everyone. The findings are about accuracy, not long-term denture success.
