Fills micro-gaps and lessens sensitivity. Protects against the recurrence of caries. Dual-cure; hardens by self-cure or light-cure. Resilient to fractures and breakage. Activa BioActive Cement bioresponsive resin contains calcium, phosphate, and fluoride that help maintain oral health. The absence of Bisphenol A, Bis-GMA, and BPA derivatives from this cement makes it ideal for indirect restorations, including zirconia, ceramic, and various metal copings.Activa is an insoluble resin that stimulates the natural remineralization process by forming a connective mineral apatite layer that bonds the restoration and the tooth. It minimizes sensitivity and chemically bonds with tooth, dentin, and enamel replacements to protect against decay and caries.The shock-absorbing component makes this adhesive resilient and fracture-resistant and results in tight seals against microleakage and failure. Activa BioACTIVE Cement is moisture-tolerant and triple-cured.Each Single Pack includes a 5 ml Syringe, 20 Automix Tips (15 Straight Black, 5 w/Bendable Metal Cannula).
