Same-visit crowns ahead? New method cuts a key 3D-printing step for zirconia crowns from days to under 30 minutes

Researchers at the University of Texas at Dallas have shortened the "debinding" stage of 3D-printing zirconia crowns from 20–100 hours to under 30 minutes. Zirconia is a strong material widely used for permanent crowns; today's same-day crowns mostly use weaker ceramic resins. The method still needs clinical validation and regulatory approval.

What it means for you

In future a strong crown might be made in a single visit, cutting time in a temporary crown; for now crowns usually take several visits.

Key points

• One step cut from 20–100 hours to under 30 minutes
• Still needs clinical validation and approval
• Crowns today usually take several visits
