Delivers all the advantages of glass ionomers in a strong, resilient resin matrix that will not chip or crumble. It chemically bonds to teeth, seals against bacterial microleakage, releases more fluoride and is more BioACTIVE- than glass ionomers. More durable and fracture resistant than composites, glass ionomers and RMGIs. ACTIVA is the first BioACTIVE- base/liner with an ionic resin matrix, a shock-absorbing resin component and BioACTIVE- fillers that mimic the physical and chemical properties of natural teeth. It releases and recharges with calcium, phosphate and fluoride ions, delivering long-term benefits and better oral health care for patients. Contains no Bisphenol A, No Bis-GMA and no BPA derivatives. The material is dual cure.
