Summary

This study compares two types of dental restorations for molars that have had root canal treatment: one made by milling from a solid block and the other by 3D printing. About 142 adults will receive either a milled or 3D-printed partial crown and be followed for three years to see which holds up better. The goal is to find out if the newer 3D-printed option works as well as the established milled version.

What this could mean

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

Active substance: Milled composite resin onlay/overlay or 3D-printed composite resin onlay/overlay
What this could lead to: If successful, this could show that 3D-printed restorations work as well as milled ones, offering a more affordable or faster option for dental crowns.
What could go wrong: This is a small, early-stage trial with only 142 participants, so results may not apply to everyone. Both types of restoration can chip or fail over time.
