ABSTRACT

Aim & Objective

All ceramic materials have been the most popular aesthetic restorations since the advancements in CAD CAM technology. Very limited evidence is available on marginal discrepancies of these materials when used to fabricate fixed restorations. The purpose of the study is to assess the vertical marginal discrepancies of the zirconia-based tooth supported fixed dental prosthesis, fabricated using ceramill® (M1), lava® (M2), and zirkonzahn® (M3) CAD-CAM milling materials.

Materials & Methods-

The vertical marginal discrepancy of these three groups was assessed using the one-way ANOVA test using the statistical software. There was no statistically significant difference (P≥0.05) in the vertical marginal discrepancies measured among all three groups.

Results & Conclusion-

Within the limitations, it is concluded that all the three CAD-CAM milling materials, when fabricated using a 5 axis CNC milling machine have provided a range of clinically acceptable vertical marginal discrepancy providing strong evidence towards their longevity.
