Dentists may soon be able to deliver durable, high-quality zirconia restorations within a single appointment, thanks to a breakthrough in 3D printing technology developed by researchers at the University of Texas at Dallas. Zirconia remains the benchmark material for permanent restorations due to its exceptional strength, durability, and biocompatibility. However, while 3D printing has advanced chairside dentistry, same-day restorations have so far relied on weaker ceramic resins or time-consuming milling processes.
Milling zirconia crowns can limit design flexibility and carry risks of micro-cracking during fabrication, while conventional 3D printing of zirconia has been slowed by one key obstacle: the lengthy “debinding” stage. In traditional processes, debinding—the step that removes resin binders before sintering—can take anywhere from 20 to 100 hours. The extended heating period…
