The opacity of aura bulk fill is a function of the difference in the refractive index of its two components, the filler and the resin. The curing process alters the refractive index of the resin marginally, to match the refractive index of the filler. This lowers the opacity temporarily, allowing deeper light penetration for a high depth of cure. Upon curing, the indices move apart again to arrive at the ideal opacity for aura bulk fill’s brilliant chameleon-like finish.
Features & Benefits:
- Natural-looking finish with just one universal shade
- High depth of cure without the need for a capping layer
- Easy placement in a matter of seconds
- The waxy consistency is packable and non-sticky to optimize handling
