Abstract
Purpose: The purpose of this study was to compare color correspondence of different sizes of Vita Mark II and TriLuxe Feldspar blocks.
Methods: The three commercially available shades(1M2, 2M2, 3M2) of Mark II & TriLuxe blocks for the CEREC CAD/CAM system were examined. For each of three colors, three different sizes were tested, 5 blocks each. The measurements were made using a spectrophotometer equipped with an integrating sphere using the CIE , , colorimetric system.
Results: The , , value of Vita Mark II ceramic block showed significantly higher than TriLuxe ceramic block(p<0.05). In comparing the Vita Mark II specimen of the three different shade, color differences between materials() showed the lowest value of 2.09, and the highest was 2.24. values of the materials of Vita Mark II were higher than 2. As the size of ceramic block differed, the color correspondence of Vita Mark II showed statistically significant difference but, this result is clinically acceptable.
Conclusion: All the different sizes of the different shades of Vita TriLuxe blocks for the CEREC system showed the high degree of color correspondence necessary in industrially prefabricated CAD/CAM blocks. The results of the present study suggested that it would be necessary to establish the reproducible and constant color specification system for an esthetic restoration.
