Estelite Bulk Fill Flow composite by Tokuyama Dental America
It seems that nearly every day another bulk-fill composite is introduced, whether as a packable or a flowable resin. So what made me stop to give this one a look and try it on several cases? For one, it carried Tokuyama’s Estelite name, and I have high regard for Estelite Sigma Quick, a great packable composite resin.
This new bulk-fill flowable composite is based on Tokuyama’s supranano technology with 200-nanometer particles. This spherical filler technology allows for strength and durability. In fact, the manufacturer reports that the compressive strength is approximately 50% higher than other bulk-fill flowables. I also liked the esthetics since I didn’t find that I needed a capping layer over the material. This flowable can be placed in 4 mm increments, and like all other flowables, it adapts nicely to the cavity walls.
But perhaps a key factor to consider in choosing this product is the ability of the material, due to the supranano spherical filler technology, to provide a natural look to the restoration by diffusing and refracting light. When you first place Estelite Bulk Fill Flow, it will appear translucent, but once it has been light cured, it will become more opaque and blend to a more natural-looking restoration. This is accomplished with only five shades: A1, A2, A3, B1, and Universal.
Couple this with Tokuyama’s very good seventh-generation bonding agent, Bond Force, and you’ll have a simple and fast method for achieving a highly esthetic and strong bulk-filled restoration.
