Abstract
The Ceram·X including nanofillers has been developed recently by Dentsply-DeTrey Co. The Ceram·X has the two series of the “Ceram·X mono” for bulk restoration and the “Ceram·X duo” for layering restoration. Seven shades (M1-M7) are lined up for the Ceram·X mono, and three enamel shades (E1-E3) and five dentin shades (D1-D4, DB) are lined up for the Ceram·X duo. The aim of this study was to observe the polished surface of the set Ceram·X under the FE-SEM with the Ar-ion etching technique. Furthermore, a clinical performance of the Ceram·X restoration in combination with the Absolute was examined. The filler composition of the Ceram·X was the glass fillers of5μm in maximum diameter, nanofillers of10nm in diameter, and the nanoparti-cles of 2-3 nm in diameter. The Ceram·X was classified into the category of traditional small filler+nanofiller. According to this clinical application, the Ceram·X showed a good clinical performance with no post-operative accident. It was suggested that the Ceram·X was very useful for anterior and posterior restorations.
