Summary

This study compares two ways of making dental onlays (custom tooth restorations) for damaged molars: milling from a solid block versus 3D printing. Thirty adults with cavities, broken teeth, or old fillings will receive either a milled or 3D-printed onlay. Researchers will check how well the onlays fit and function over one year using digital scans and clinical exams.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: dental onlay (milled or 3D-printed ceramic restoration)
What this could lead to: If successful, this could show that 3D-printed onlays are as good as milled ones, offering a faster or cheaper option for dental restorations.
What could go wrong: This is a small, early-stage trial with only 30 participants, so results may not apply to everyone. The study focuses on short-term fit and function, not long-term durability.
