Dental crown showdown: which design fits best?
NCT ID NCT06500845
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests two different preparation designs (bevel vs. butt) for Peek endocrowns, which are tooth-colored caps for molars that have had root canals. Researchers will check how precisely each design fits the tooth, using a replica technique and microscope. The goal is to see which design gives a better fit, potentially improving dental restorations.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance

What this could lead to
If successful, this could help dentists choose the best preparation design for durable, well-fitting dental crowns after root canal treatment.
What could go wrong
This is a small, early-stage trial with only 24 participants, so results may not apply to everyone. It focuses on fit, not long-term success or patient outcomes.
