Could 3D-Printed grafts make dental implants more precise?
NCT ID NCT07774052
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This trial tests whether a patient-specific 3D-printed polylactic acid (PLA) graft can improve the stability and accuracy of immediate dental implants in lower molars compared to the standard xenograft method. Participants needing a molar extraction and immediate implant will be randomly assigned to receive either the 3D-printed guide and scaffold or the conventional freehand approach with xenograft. The study measures implant stability and how closely the final implant position matches the digital plan, with follow-up over six months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Patient-specific 3D-printed polylactic acid (PLA) socket guide and root-form scaffold
- What this could lead to
- If successful, this could offer a more precise and potentially safer method for immediate dental implants, reducing the need for animal-derived grafts.
- What could go wrong
- This is a small, early-stage trial with only 17 participants, so results may not be generalizable. The PLA scaffold may not integrate as well as xenograft, and there is a risk of implant failure or complications.
