H. BRAUNER1, S. REICH1, and M. HERRGUTH2, 1Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany, 2Nürnberg, Germany Objectives: The aim of this study was to examine whether machinable monochromatic Cerec™ Vitablocs™ can compete in color match with an individual layering technique (Cergogold™). Methods: Twelve single anterior crowns in 11 patients needed to be restored. The color determination was conducted using the respective shade guide. Then full-ceramic crowns made of Cergogold™ [CERGO], Cerec™ Vitablocs™ Mark II in classical [MKCL] and 3D-Master® [MK3D] colors and, additionally, stained Cerec™ Vitablocs™ [MKST] were tried in. Three independent examiners assessed the color match using marks from 1 to 6, and a mean mark out the three was computed. Results: The acceptability range was up to 3.5. [MKCL] showed marks from 2.3 up to 5.4 (two restorations below 3.5) and [MK3D] from 2.3 up to 5.0 (six below 3.5). The [MKST] and [CERGO] crowns were below 3.5. Conclusion: The results of these clinical cases showed that machinable ceramics can compete with layered ceramics by the use of staining pastes. | ||
