Abstract
Purpose: CAD/CAM feldspathic ceramic (FC) materials remain used for their low cost and ease of chairside production. The purpose of this study was to describe preliminary clinical results, reporting the success and survival of FC dental crowns in a high-demand service using a simplified CAD/CAM technique.
Materials and methods: A calibrated dentist fabricated indirect restorations using the CEREC method and intraoral scanning (Cerec Omnicam, Cerec MCXL) for high-demand dental care. Forty crowns were seated adhesively and evaluated after 24 months using the newly validated UERJ criteria. Statistical analysis was performed with the McNemar test (p⟨.05).
Results: The survival clinical rate of FC CAD/CAM crowns after 24 months was 100%. However, 65% of indirect restorations presented reparable complications. No failure with loss of restoration was detected. Within the complications, most parts were in the proximal contact point, with statistically different significance in follow-up.
Conclusion: This study demonstrates that FC CAD/CAM crowns made using a simplified technique have a high clinical survival rate after 24 months, which is crucial for high-demand service. A more extended clinical evaluation period using the same criteria is necessary to draw further conclusions.
