Trueness of three-dimensional printed zirconia prosthesis with digital light processing as a build angle

Results:The root mean square (RMS) values for the internal segments were 40.23 (0), 53.01 (30), and 82.49(60) m.The marginal segments recorded RMS values of 34.63 (0), 59.97 (30), and 84.16 (60) m.Statistical analysis revealed significant differences among the groups (p<0.001). Conclusion:The results indicate that a 0 build angle with uniform height support struc- tures provides the highest accuracy in digital light processing of 3D printed zirconia crowns.
