The FUSION’s high power output carries the polymerizing photons further into the composite, making the active working distance longer and allowing deeper bulk curing of the composite restoration. In fact, as composites with ever lower polymerization shrinkage properties are developed, the FUSION curing light may allow single-step bulk curing of these materials (as opposed to the slower, Â sequential curing of individual thin layers).
