3D printed aligners may offer more precise tooth movement than traditional ones
NCT ID NCT07496892
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will compare how accurately 3D printed aligners move teeth versus standard thermoformed aligners in people with mild crowding of the lower front teeth. Twenty-eight participants aged 12 to 25 will be randomly assigned to one of the two aligner types. The main goal is to see if the 3D printed version achieves the planned tooth positions more precisely.
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 aligner and thermoformed aligner
- What this could lead to
- If 3D printed aligners prove more accurate, this could lead to more predictable and efficient orthodontic treatment for mild crowding.
- What could go wrong
- This is a small, early-stage trial with only 28 participants. Results may not apply to more severe cases or other populations. The study compares accuracy, not long-term outcomes.
