Summary

This study tested a fully digital method for gum reshaping (gingivectomy) to fix a gummy smile, comparing it to the conventional technique. Twenty-four adults with excessive gum display due to altered passive eruption took part. The digital approach used 3D scanning and printing to create a surgical guide, aiming for better accuracy and patient satisfaction.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Fully digital guided gingivectomy procedure
What this could lead to
If successful, this digital approach could offer a more precise and satisfying option for correcting a gummy smile, reducing the need for manual guesswork.
What could go wrong
This is a small, completed study with only 24 participants, so results may not apply to everyone. The procedure is cosmetic and does not treat a medical condition.
