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.
Editors' take: the background
A crown is a cap that covers a damaged tooth. Common materials are porcelain fused to metal, all-ceramic and zirconia. Traditionally the tooth is shaped and scanned or moulded, a temporary crown is fitted, and the final crown is placed at a later visit.
3D printing and chairside milling (making the crown in the surgery) are both part of digital dentistry. New methods need clinical testing and regulatory approval before they reach clinics.
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

Questions readers ask
How many visits does a crown take now?
Usually two or more: one to prepare the tooth and take a scan or mould, another to fit the final crown. Some clinics offer same-day crowns, with fewer material choices.
What's good about zirconia crowns?
They are strong, hard-wearing and tooth-coloured, so they are often used on back teeth. Whether one suits you depends on your bite and the tooth.
