4.0 Composition
KALORE consists of a matrix, fillers, photo initiator and pigment (Table 1).
4.1 Matrix
The matrix contains a mixture of urethane dimethacrylate
(UDMA), dimethacrylate co-monomers and DX-511 monomer.
4.2 Filler
newly developed high-density radiopaque (hDR) pre-
polymerized fillers are at the core of the KalORe filler
system. These fillers contain 60% wt. 400 nm nano-sized
modified strontium glass and 20% wt. 100 nm lanthanoid
fluoride. The modified strontium glass reinforces the filler’s strength and surface hardness, provides
high polishability, and matches the refractive index of the UDMA resin matrix, thereby offering
improved esthetics (the barium glass commonly used in composites has a higher refractive index
than uDma resin, resulting in decreased translucency and poorer esthetics). lanthanoid fluoride is
added to increase the radiopacity. the combination of 17 µm particle size hDR filler and 30% wt.
volume guarantees optimal handling. 700 nm strontium glass particles, fluoroaluminosilicate glass
and nano-sized silica are dispersed between the hDR fillers (Fig. 1). the modified strontium glass
and fluoroaluminosilicate glass each have slightly differing refractive indices to provide complex
light reflection and light scattering for a chameleon effect.
