Estelite Bulk Fill Flow is a light-cured, flowable bulk fill composite that utilizes spherical filler technology (70% by weight/ 56% by volume) to deliver simpler restorations with superior final results – no additional layers or composites needed up to 4mm. Higher shade, opacity, and glossiness offer greater esthetics, while higher compressive and flexural strength, higher wear resistance, lower shrinkage stress, and excellent cavity adaptation provide worry-free restorations that last.
