Morphological aspect of Filtek Supreme XT after 6 years of
simulated wear (8,000). A similar pattern can be observed
compared to 1, 2, and 4 years suggesting maintenance of
roughness as presented in Figure 4.15 .

The wear resistance depends upon the filler weight content (as described in Section 4.6), organic
phase, and silanization. In 2002, Kim et al. [25] suggested the use of smaller particles in order to
improve the filler load, reducing the exposure of organic resin to wear that was confirmed later by
Yesil et al. [26] . The effect of this wear ( Figure 4.20 ) in a nanofilled composite (Supreme XT) is mea-
sured by surface roughness (μm) and is presented in Figure 4.21 .
4.9 CLINICAL APPLICATIONS
The following clinical report ( Figures 4.22-4.26 ) illustrates an interproximal restorative procedure in
a 20-year-old male patient with nanofilled composite resin.
