Dental overlay showdown: which cavity design lasts longer?
NCT ID NCT07614451
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at two different ways to prepare a tooth for a dental overlay after a root canal. Fifty adults with treated molars will get either a traditional retentive design or a newer, less invasive non-retentive design. Over two years, dentists will check how well each restoration fits, wears, and holds up. The goal is to see which approach works better for everyday dental care.

Active substance
hybrid ceramic overlay
What this could lead to
If successful, this could help dentists choose the best cavity design for durable, long-lasting overlays on root-canal-treated molars.
What could go wrong
This is a small, early-stage trial with only 50 participants, so results may not apply to everyone. The study only lasts two years, so long-term performance remains unknown.
