From Micerium® (Italy)
ENA HRi® Bio Function is a composite material with unique characteristics for all direct and indirect restorations in the anterior or posterior. It does not contain co-monomers, bis-GMA or bisphenol-A. It does not release free nanoparticles.
Its unique formulation is highly wear-resistant, offering a wear rate similar to that of natural dentin or gold, making it ideal for direct or laboratory fabricated posterior restorations, such as restorations on implants, onlays, single crowns or full arches.

NEW Biocompatible Composite
Bio Function offers a perfect integration in harmony with the human body without releasing any toxic substances. It cures in the highly stability resin matrix that does not releases and free nanoparticles in the powders generated by finishing and polishing that can be absorbed by the body.
