Researchers at Japan’s Tohoku University Graduate School of Dentistry have found Digital Light Processing (DLP) 3D printing to be a more effective means of producing dental crowns than conventional milling.
In a recent study, the dentists 3D printed and wet-milled crowns from the same dataset, before superimposing their intended design over resulting models. Through several testing cycles, the team said their 3D printed dental restorations showed “higher accuracy” and “fewer marginal discrepancies” than milled alternatives, thus they see DLP as a more “promising technology” for permanent crown creation.
Time to move on from milling?
As the wear-resistance and color stability of dental materials continue to improve, some dentists are turning to milled…
