Effect of build orientation on marginal and internal discrepancies of zirconia crowns fabricated by using digital light processing 3D printing: A clinical study.
Zirconia crowns fabricated at 0-degrees build orientation using the TD-6 DLP printer and 3DCera 3Y TZP slurry exhibited marginal and internal discrepancies comparable with those of Ceramill Zolid FX 4Y PSZ conventionally milled crowns, whereas 45- and 90-degree build orientation resulted in inferior adaptation, particularly at the occlusal surface.
