ABSTRACT
The aim of this study was to evaluate the accuracy and adaptation of all-ceramic zirconia crowns fabricated by stereolithography (SLA) compared with computer-aided design/computer-aided manufacturing (CAD/CAM) milling technology. Ten all-ceramic zirconia crowns each were fabricated with SLA (experimental group) and CAD/CAM numerical control milling technology (control group). The accuracy (including trueness and precision), and the internal and marginal adaptation of the crowns were measured with the optical impression and silicone rubber film method and the three-dimensional deviation analysis software Geomagic studio, and the results were statistically analyzed. The results indicated no statistical difference in trueness and the occlusal, axial and marginal adaptation between groups (p>0.05), and the precision in the SLA group was better than that in the milling group (p<0.05). Thus, crowns fabricated with SLA meet clinical application requirements.
