IPS Empress Direct,###50.2% Barium glass filler, mixed oxide, Nanohybrid###Ivoclar Vivadent, AG,
This can be attributed to the composition of the IPS Empress Direct composite which contains 50.2% Barium glass filler, mixed oxides and Ba-Al-fluorosilicate glass and 20.0% Dimethacrylate (Table 1).
This is the first ruby we have seen in our laboratories that has been filled with a high-refractive-index barium glass. Depending on the Ba content, such glass can have a refractive index above 1.7 (the RI of the glass in this sample could not be determined since the cavities were not large enough to measure it).
The Panavia F 2.0 contains 10-MDP as functional monomer; filler particles composed of silica and barium glass and hydrophobic aromatic dimethacrylate, hydrophobic aliphatic methacrylated, and hydrophilic aliphatic dimethacrylate monomers to form a highly cross-linked cement matrix after polymerization.
