Digital dental scans may beat goopy impressions for speed and comfort
NCT ID NCT07705009
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This trial compares two ways of taking dental impressions: the traditional method using alginate (a goopy material) and digital scanning with two different intraoral scanners. The study involves 171 dental students aged 18 to 24, who are randomly assigned to one of the three techniques. Researchers measure how long each procedure takes and ask participants about their comfort, nausea, pain, and overall satisfaction right after the impression is made.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- intraoral scanning (TRIOS 3 and Medit i700) compared with conventional alginate impressions
- What this could lead to
- If digital scanning proves faster and more comfortable, it could become the preferred method for dental impressions in young adults.
- What could go wrong
- This is a small, single-center study in healthy dental students, so results may not apply to older patients or those with complex dental conditions.
