Dental material showdown: which overlay lasts longer against natural teeth?
NCT ID NCT07689032
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This trial compares how two types of dental overlays—a CAD/CAM hybrid ceramic and a nano-hybrid composite—wear down over 24 months in root-treated molars. It also measures wear on the opposing natural teeth. Participants are adults aged 22–45 with good oral health and normal bite. The goal is to see which material holds up better and causes less damage to natural teeth.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- CAD/CAM hybrid ceramic overlay (SHOFU Hard blocks) and nano-hybrid composite overlay (BRILLIANT Crios)
- What this could lead to
- If one material wears less, dentists may choose it for longer-lasting tooth restorations 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. Wear is measured digitally, but real-world performance could differ.
