With a filler weight of 82% (71% volume), the spherical fillers provide a uniform diffusion of light, allowing for a more forgiving shade match and superb blend to surrounding teeth. In addition, the spherical fillers provide low composite wear over time and are safe for opposing dentition while causing less wear on opposing teeth.
