- 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 L*, a*, b* colorimetric system.
Results: The L*, a*, b* 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(ΔE*) showed the lowest value of 2.09, and the highest was 2.24. ΔE* 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.
