Digital vs. goo: which dental impression method leads to more accurate implants?
NCT ID NCT03764176
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This trial investigates whether taking a digital scan of the mouth is as accurate as traditional putty-like impressions for planning dental implant surgery. About 40 adults needing dental implants will be randomly assigned to either a digital or conventional impression method. Researchers will then compare how closely the final implant position matches the planned position, as well as any early implant problems.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If digital impressions prove as accurate as conventional ones, dental implant procedures could become faster and more comfortable for patients.
- What could go wrong
- This is a small, early-stage trial with only 40 participants, so results may not apply to all patients or implant types. The study focuses on accuracy, not long-term implant success.
