First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a custom digital surgical guide helps dentists perform crown lengthening more accurately than the usual method. Twenty-four adults with gummy smiles due to a condition called altered passive eruption took part. The digital guide uses 3D scans and imaging to plan both gum and bone removal, while the traditional method relies on the dentist's visual judgment and manual measurements. The researchers measured how much tooth showed after three months, along with surgery time, pain, and satisfaction.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Dual digitally fabricated surgical guide (procedure)
- What this could lead to
- If successful, this digital guide could make crown lengthening surgery more precise, faster, and less painful for patients with gummy smiles.
- What could go wrong
- This is a small, early-stage trial with only 24 participants, so results may not apply to everyone. The digital guide may not improve outcomes enough to justify its cost or complexity.
