Can a 3D-Printed tooth preserve your gum line after extraction?
NCT ID NCT07748871
First seen Aug 06, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This trial tests two methods for sealing the socket left after a tooth is removed, with the goal of preserving the gum and bone for a future replacement. One method uses a fixed, 3D-printed temporary tooth that supports the gum tissue, while the other uses a removable plastic guard with a collagen seal. Both groups receive a bone graft to maintain the ridge. The study measures how well the gum height between teeth is maintained at 5 months, using digital scans.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Fixed ovate pontic provisional restoration (3D-printed) versus removable Essix provisional with collagen matrix seal, both with socket grafting using Bio-Oss Collagen (deproteinized bovine bone mineral with collagen)
- What this could lead to
- If successful, this could point to a better way to preserve gum and bone shape after tooth extraction, potentially improving the fit and look of future dental implants.
- What could go wrong
- This is a small, early-stage trial with only 40 participants, so results may not apply to everyone. The fixed provisional may cause discomfort or require more maintenance, and the outcome depends on individual healing.
