Can a 3D-Printed plastic guide make dental implants more precise?
NCT ID NCT07826039
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers compare two computer-guided surgical guide systems for placing dental implants immediately after removing a lower molar. One guide is custom 3D-printed from polylactic acid (PLA), the other is a modified resin guide. Twenty adults with a non-restorable lower first molar receive one of the two guides. The trial measures how closely the actual implant position matches the digital plan, how stable the implant is right after placement, and how long surgery takes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a patient-specific 3D-printed polylactic acid (PLA) surgical guide for dental implant placement
- What this could lead to
- If the 3D-printed PLA guide proves accurate and stable, it could offer a cheaper, faster way to place dental implants right after a molar is removed.
- What could go wrong
- This is a small, single-center study of 20 people with healthy mouths and enough bone, so results may not apply to patients with gum disease, bone loss, or other health conditions. Guide accuracy also depends on how well the digital plan matches the actual jaw.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 20-50 years. * Non-restorable mandibular first molar indicated for extraction. * Sufficient bony support for implant placement without the need for significant bone augmentation. * Good oral hygiene and motivation. * Adequate prosthetic space. * Ability and willingness to undergo the surgical procedure and follow-up. * Suitable for computer-guided, tooth-supported implant placement. Exclusion Criteria: * Uncontrolled systemic diseases that may impair healing (e.g., uncontrolled diabetes or hypertension). * Severe periodontal disease. * Patients undergoing chemotherapy or radiotherapy. * Insufficient prosthetic space. * Heavy smokers.
