One-Visit crowns: stronger ceramic could change dentistry
NCT ID NCT04604301
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new high-strength ceramic material for dental crowns that can be made in a single appointment using a computer technique, avoiding the need for a temporary crown. 48 adults with a decayed, fractured, or poorly restored molar or premolar will receive the crown and be followed for up to 5 years to see how well it holds up and whether it causes tooth sensitivity.

Active substance
Celtra Quatro ceramic crown
What this could lead to
If successful, this could lead to stronger, longer-lasting dental crowns that can be made in a single appointment, reducing patient visits.
What could go wrong
This is a small, early-stage study with only 48 participants. The crowns may still fail or cause tooth sensitivity over time.
