Summary

This study tested a custom 3D-printed PEEK shell placed under the gum in the upper jaw to reduce excessive gum display (gummy smile) in 10 patients. The shell was inserted through small incisions using a tunnel technique. The goal was to see if it could decrease the amount of gum showing when smiling, while also measuring pain, lip movement, 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: 3D-printed PEEK shell placed via tunnel technique
What this could lead to: If successful, this could offer a new, minimally invasive option to reduce a gummy smile without major surgery.
What could go wrong: This is a very small case series (10 people) with no control group, so results may not apply to everyone. Long-term safety and effectiveness are not yet known.
