UT Dallas researchers report reducing zirconia crown processing time from up to 100 hours to under 30 minutes.
The work could enable same-day permanent 3D-printed restorations instead of relying on weaker resin prints or milled zirconia.
Commercialization efforts are underway with NSF support for crowns, bridges, veneers, and related dental applications.
